Add support for RHEL/centos to installdeps. There is no SFML package.
Add some string compatibility stuff so that everything builds on wx 2.8
unicode builds.
TODO: add travis slaves for 2.8, with and without unicode
Disable the game frame spacer code on 2.8 because it does not work (the
frame does not expand.)
cmake improvements:
- set ENABLE_LTO=OFF for Debug builds by default
- set ENABLE_LINK=OFF if SFML cannot be found and continue
- use better logic for finding wx utilities wx-config and wxrc

Closes#395Closes#297
Do some reformatting towards the more modern cmake style.
Clean up some code.
Support linking to gcc compiled wxWidgets by setting
`-D__GXX_ABI_VERSION=` appropriately for clang.
Use the new method of calling `FindwxWidgets.cmake`, the old method
causes some problems now.
Set all necessary policies in both cmake files.

Ninja requires `-fdiagnostics-color=always` instead of
`-fdiagnostics-color=auto` with gcc because it pipes output from the
compiler unlike regular makes.
Use `-fcolor-diagnostics` for clang, which also works correctly with
ninja to show colors.

Use vcpkg to build deps when Visual Studio on Windows is detected, this
only happens on first build, but does take a while because things like
wxWidgets need to be built. Building from the developer command line is
also supported.
I considered making a pre-built tarball available, but the resulting
files are just too big for this to be practical.
Make the necessary cmake code changes for this to work and to use the
vcpkg packages, which work just like on linux or have other cmake glue
code available.
To do this, we make vcpkg a submodule, use git to checkout all
submodules, then just build and use the `vcpkg.exe`. Then we set the
CMAKE_TOOLCHAIN_FILE to the vcpkg toolchain and also include it
directly, why this is necessary I don't know, without it it doesn't work
in the IDE but does on the command line.
All of this requires no vcpkg integration with either the user or the
project. A user-wide `ENV{VCPKG_ROOT}` is also supported.
Fix the dynamic arrays in the GBA core, MSVC follows the C++ standard on
this and gcc does not.
TODO: add the necessary gcc flags to make this an error in cmake.
Use `wxArrayString` instead of `std::vector<wxString>` in
`src/wx/strutils.cpp` which is used in options parsing. This was
necessary because of a bizarre linker error with wxWidgets when using
Visual Studio:
https://trac.wxwidgets.org/ticket/10884#comment:46
In `src/wx/panel.cpp` make sure the unimplemented D3D renderer code does
not get compiled if it's actually `OFF`.
Also fix the new spacer code for the drawing panel to not combine
`wxEXPAND` with `wxALIGN_CENTER`, which is an error on wxWidgets 3.1.2,
which is what vcpkg uses. The drawing panel seems to be automatically
stretched to the max size automatically anyway.
TODO: if all of this works, we'll need an Appveyor set up for visual
studio.

When using msys ccache with a mingw ninja, the compiler fails to
execute.
Don't try to detect ccache when using the Ninja generator on msys2, it
can still be specified through cmake variables.
Do not check for the mingw ccache because it is broken and I will assume
not being used.

Test for the -fdiagnostics-color=auto compiler option supported by gcc
and probably clang, and turn it on if it's available.
This option colorizes compiler warnings/errors/etc. when output to a
terminal.
Also fix a typo above when adding the -fopenmp flag.
Older versions of mingw64 do not have the versionhelpers.h header, add
it to the dependencies submodule include/ directory and add it to
include_directories() for mingw in cmake.
In cmake on Win32, don't try to find librt or libpthread using
find_library(), and on mingw just include -lpthread.
For some reason the msys versions of librt and libpthread were being
picked up when find_library() was being used.
Make gcc -fstack-protector-strong and associated options controlled by
the cmake option ENABLE_SSP which defaults to OFF.
This option causes a segfault on startup with gcc 8.2.0.
Remove -fpermissive from the list of flags passed to gcc and clang.
Remove -fpermissive from the cxxflags from wxWidgets config as well.
When checking wxWidgets ABI compatibility version, temporarily add
-fpermissive to compiler flags on Win32 because minhook requires it.
Make mac builder use -m32 in CFLAGS etc. to produce a 32 bit binary
targetting 10.7 (Lion.) This provides the greatest backward
compatibility for older macs, and also allows for asm filters.
Fix an issue with m4 on 10.13 using a patch from macports.
Support `-pX` patch level args in DIST_PATCHES in builder.
Fix an issue with bison on 10.13 by bumping the version to 3.0.5.
Build libxslt `--without-crypto` so that it doesn't try to link the brew
libgcrypt.
Invoke cmake for dists with -DCMAKE_C_COMPILER_LAUNCHER=ccache and
-DCMAKE_CXX_COMPILER_LAUNCHER=ccache to use ccache, and set
CMAKE_C_COMPILER and CMAKE_CXX_COMPILER to the actual compilers not
prefixed by ccache.
When checking for ccache in vbam cmake code, check that
CMAKE_CXX_COMPILER_LAUNCHER and CMAKE_C_COMPILER_LAUNCHER were not
already defined (generally on the command line.)
Remove align attributes from sections in 2xSaImmx.asm, macho format on
mac does not support this and the filter works fine without them.
In the Quartz2D renderer, pass the NSRect view.bounds through
NSRectToCGRect when calling CGContextDrawImage(), this is necessary for
the 32 bit API.
Bump openssl to 1.0.2o.
Bump libxml2 to 2.9.8.
Update URL for urw fonts, and improve the dist downloading/unpacking
code to handle URLs that do not contain the filename (for .tar.gz and
.zip as identified by `file`.)
Change post-build for harfbuzz from `rebuild_dist freetype;` to
`rebuild_dist freetype --with-harfbuzz=yes;` as it was supposed to have
been.
Build cmake itself with --parallel and --enable-ccache.
Silence errors from killed jobs due to tmp directory being gone.
Write a couple of string functions, rtrim() and gsub().
Make path_exists() handle globs with spaces in them, by escaping the
space.
Use --host and --build args to autoconf configure to "cross-compile" for
32 bits, this is necessary for some dists, and does not work for others,
remove it for dists where it does not work.
Add COMMAND_MODE=unix2003 to the build environment, this is necessary to
fix some build errors, why I have no clue, found it on stackoverflow.
Pass -Wl,-no_compact_unwind in LDFLAGS to openssl, this is necessary for
32 bits.
Force sfml to compile as 32 bit, it normally does not allow this.
Remove shared-mime-info from this build, it's not necessary for anything
and there are issues XML::Parser linked to our expat and brew perl that
need to be resolved.
Use a matrix of 4 jobs, linux (ubuntu trusty), mingw i686, mingw x86-64
and mac.
Automatically detect ccache in the cmake config and cache the
`~/.ccache` directory for faster rebuilds.

Change build status badge in README.md to Travis.
under `tools/` add some scripts to invoke the build system to build all
deps for vbam and vbam itself:
- `tools/linux/builder`
This builds a mostly static linux binary with a few dynamic deps for
xorg and wayland. Using gtk3. This will run on just about any dist.
- `tools/osx/builder`
Builds a static mac app targetting 10.7.
- `tools/win/linux-cross-builder`
Builds a static windows binary using the mingw-w64 toolchain.
- `tools/win/msys2-builder`
Builds a static windows binary in the MSYS2 environment, this may be
suffering from a few regressions.
Change some cmake code to support the build system, refactor a few
things in it.
`git submodule update --remote --recursive` must be called with `--init`
if the submodules have never been initialized, add the flag to the cmake
code that does this. If they are already initialized, it will not cause
any harm.
Improve, refactor and clean up `tools/osx/builder` to build a relatively
full-featured ffmpeg as well. This requires lots of other dists. It's
kind of like a mini port system now. Will generalize it shortly to a
sourced library for using with both the mac and the mingw builds. Will
hopefully become a separate repo on github at some point.
Add perl dist support to the builder.
Add an `--env` flag to the builder to print the build environment
variables so that they can be read in with `eval` for debugging
purposes.
Also add the `FFMPEG_STATIC` cmake option to link static ffmpeg
libraries correctly.
Move the codesigning and zipping of the `.app` bundle to the builder
script and out of cmake, as this is something most users don't need.
Add `tools/osx/builder`, a POSIX sh script to build all dependant
libraries as static, targetted to OS X 10.7, and build the project with
them (also targetted to OS X 10.7.)
ffmpeg currently does not link, as recording functionality is currently
non-functional anyway, this will be fixed later.
MISC:
- set WORKING_DIRECTORY and ERROR_QUIET for all git commands, for the
cases when the build directory is not under the git checkout
- #include <cerrno> in ConfigManager.cpp as it uses errno
- change `build*` in `.gitignore` to `build/*` so that files starting
with "build" are not affected
If git tags are not available, set the version and revision by finding
the first version tag in `CHANGELOG.md` of the form
```
```
Where N.N.N is the number version (number of components can vary) and
the revision (as speicified by -REV) is optional.
TODO: support named revision without a version number of the form
`[REV]`.
Fix `cmake/GitTagVersion.cmake` to not throw errors when in a shallow
git clone, or any git clone that has no tags.
And when either git or git tag version info is not available, set the
version variables to the defaults, which are:
```
VERSION = '2.0.0'
REVISION = 'unknown'
VERSION_RELEASE = 0
```
To get the version, find the last tag in git tag of the form "v2.0.0" or
"2.0.0". If this is the last tag and the current commit matches the ref
of this tag, the revision will be empty.
In the case that the current commit is not tagged with a version, to get
the revision, use the short sha unless the current commit is tagged with
something that is not a version string, e.g. "feature-foo", in which
case the revision will be "feature-foo".
If the current commit is tagged as e.g. "v2.0.1-foo" or "2.0.1-foo" then
the version will be "2.0.1" and the revision will be "foo". Tags of this
form are also checked when finding the current version.
This is all done in cmake. If there is no git detected, the version will
be "2.0.0" and the revision will be "unknown".
64 bit MinGW (e.g. msys2 64 bit) produces a binary that immediately
segfaults when built with LTO.
Make ENABLE_LTO default to OFF on 64 bit MinGW (32 bit will still
default to ON.)
Use the `cmake` `ProcessorCount` module to determine the number of CPU
threads, and set the `-flto` flag for gcc to `-flto=${num_cpus}` if the
number of CPU threads is detected and is greater than `1`.
clang does not support this.
Use `git submodule update --remote --recursive` instead of `git
submodule update --init --recursive` so that the latest version of the
repo is always installed.
Run the command from cmake instead of throwing an error if the submodule
is not checked out. Only throw an error if the checkout failed or the
source tree is not a git checkout.
Don't add the `mingw-xaudio` include directory if using MSVC.
Remove the submodule check from src/wx/CMakeLists.txt, having it in the
main CMakeLists.txt is enough.
gcc lto wrapper commands such as `gcc-ar` will segfault with some
versions of gcc 7.x when called via an absolute path, see:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80717
Generalize the mechanism for compiling a small C program on the host
(currently used for bin2c for Wx resources) and use it to wrap the gcc
wrappers in a little executable that prepends their dirname to PATH and
runs them with `execvp()`.
Make LTO default to ON again, except on win32 with gcc < 7, because
those toolchains produce broken binaries with LTO enabled.
Also add `-ffat-lto-objects` to compiler flags for gcc when LTO is
enabled, this will increase the chances that the LTO build will succeed
even if there are issues with the binutils wrappers. Clang does not
support this.
In 4e665ae I hardcoded -fabi-version=2 for g++ flags, and @ArtiiP
pointed out that this is wrong, because Wx may be compiled with other
ABI versions.
Add cmake check_cxx_source_runs() tests to determine the correct ABI
version flag to use with Wx.
Use the g++ `-fabi-version=2` compiler option, as suggested by @ArtiiP
to fix problems similar to:
```
Fatal Error: Mismatch between the program and library build versions
detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1002,wx
containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1009,wx
containers,compatible with 2.8).
Aborted
```
Turn LTO off by default until I fix it for newer gcc/binutils, currently
with gcc7 ar segfaults linking vbamcore.
This flags breaks the build on e.g. ARM, so only use it when a PC
architecture (x86 or amd64) has been detected. Thanks to ZachBacon for
spotting this.
ConfigManager does not use any version info, but is part of libvbamcore,
so removing the `#include` makes rebuilds after git changes much much
faster.
Remove the AutoBuild.h includes from ConfigManager.cpp and SDL.cpp (the
SDL port) because the information in that file does not seem to be used
and it also includes version.h, forcing those files to rebuild
unnecessarily.
Use cmake to generate the version.h from version.h.in which is a cleaned
up version of the old version.h with the git short sha into the build
directory, and include the version.h from there.
Continue to use the GetGitRevisionDescription plugin to make the cmake
configuration state depend on the current sha of HEAD, but throw away
the results (for the time being.)
This makes rebuilds after git changes such as a commit only recompile a
couple of files instead of the whole tree.
As cmake now warns when policies are set to OLD, change the CMP0005
policy to NEW.
What this does is have cmake escape -D preprocessor definitions passed
to e.g. add_definitions() starting in cmake 2.6 . This is fine since the
minimum cmake version we support is 2.8.12 . It also makes the code
cleaner since we don't have to escape quotes anymore ourselves. This
will also work better on different platforms, where different escapes
may be needed.
Remove all quote escapes from string params to add_definitions() for
this policy change to work.
The inline assembly in src/gba/GBA-thumb.cpp which is turned on with the
cmake ENABLE_ASM_CORES option, sometimes causes weird behavior on
windows (see: #54) and a crash on startup in linux (see: #98, confirmed
on both Fedora and Arch Linux.)
Previously the default for this option was ON for 32 bit builds, set the
default to OFF always for the time being, until it is either fixed or
replaced.
In 82c8a1e3 I made "--param ssp-buffer-size=4" one argument instead of
two because when added to CMAKE_REQUIRED_LIBRARIES the ssp-buffer-size=4
part was being recognized as a library, breaking the compile tests.
This broke the build on mac, which I fixed in 915e2d1e by using ssp
flags for gcc only and not clang.
Now apparently it is breaking mxe, so instead of adding this particular
parameter to the MY_C_FLAGS variable which is then added to
CMAKE_REQUIRED_* variables for compile tests, add it directly via
ADD_COMPILE_OPTIONS().
This should hopefully resolve any remaining issues with this compiler
flag.
In 82c8a1e3 I made "--param ssp-buffer-size=4" one argument instead of
two to fix another problem when passing compiler flags to
CMAKE_REQUIRED_LIBRARIES, clang cannot deal with this and this breaks
the build on mac.
Enable libssp related flags for gcc only, because clang does not support
them anyway. This fixes the build issue on mac.
Stop saving and restoring the CMAKE_REQUIRED_* variables for the compile
test, because the subsequent Wx header symbol tests need them set up for
Wx support as well.
Also --param foo=bar needs to be a single string in the list of compiler
flags, or cmake can misinterpret the second part as a library when it is
passed to libraries/link-options.
mxe leaves CMAKE_SYSTEM_PROCESSOR empty, so detect if mxe is being used
and set the variable based on CMAKE_TOOLCHAIN_FILE, this allows the
32bit asm to compile under mxe.
Also if no toolchain file is being used and CMAKE_SYSTEM_PROCESSOR is
empty, fall back to CMAKE_HOST_SYSTEM_PROCESSOR.
When determining gcc/clang flags, save resulting C flags as MY_C_FLAGS,
C++ flags as MY_CXX_FLAGS, and linker flags as MY_C_LINKER_FLAGS, then
use them in the Wx OpenGL compile test.
This fixes the test erroneously failing on git mxe on mac.
Also, don't use -fPIC on Win32, set Wx defines separately from the test,
and save all CMAKE_REQUIRED_* variables before the test and restore them
afterwards.
