In a construct such as:
```cmake
if($ENV{FOO} MATCHES bar)
...
endif()
```
if the environment variable is not set, the if statement becomes a
syntax error because there is nothing being compared.
Fix this by quoting the environment variable like so:
```cmake
if("$ENV{FOO}" MATCHES bar)
...
endif()
```

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.

Use `clang -print-prog-path=<tool>` to find the locations of llvm
toolchain utilities such as `llvm-ranlib` and set the appropriate cmake
variables to the resultant paths.

Generalize regex and glob against `wx/config` scripts in
`Toolchain-cross-m32.cmake` to work on gentoo, which can append the
`-gtk3` suffix.

For some reason on Ubuntu 14 (trusty) cmake translates `<INCLUDES>` in
`CMAKE_ASM_NASM_COMPILE_OBJECT` as a literal `INCLUDES` which produces
an error, remove it because we are not using it anyway.

Support the gentoo crossdev mingw environment for the mingw cross
builder:
- For the cmake toolchains, add /usr/<arch>/usr to root paths, as this
is the mingw root for crossdev.
- -Wno-error=all no longer works with gcc 8.2, instead remove all
-Werror flags in dist_post_configure().
- Also remove all -I/usr/include flags in dist_post_configure().
- Don't prepend ROOT/host/bin to the PATH globally, only in
set_host_env(). This way the target config scripts are correctly found
in PATH.
- Bump openssl 1.0.2o -> 1.0.2p, cmake 3.10.3 -> 3.13.0-rc1, gd 2.2.4 ->
2.2.5 and glib 2.57.2 -> 2.58.1.
- Add libicu unicode handling library, needed by some deps. Put into the
list of dists that must be built for both the host and the target. Use
a whole bunch of patches from MSys2 for it.
- Make openssl build in parallel by using a sed script to prepend a + to
the appropriate make rules.
- Replace fontconfig EXTRA_LIBS with MAKE_ARGS: LIBS="-lintl -liconv"
because these libs were being stripped out from LIBS and LDFLAGS.
- Add V=1 VERBOSE=1 to all make invocations for extra verbosity (to see
compile/link invocations.)
- As a consequence, use dist_ninja_args() for ninja, it will still take
options in DIST_MAKE_ARGS.
- Add CONFIGURE_TYPE "cmakeninja" which is like the "cmake" type except
with -G Ninja to use the ninja generator and built with ninja. Nothing
uses this yet.
- Fix dist_patch() output for already applied patches.
- Add -L/usr/<arch>/usr/lib64 to CFLAGS/CXXFLAGS/OBJCXXFLAGS/LDFLAGS,
because crossdev libpthreads.a is in that directory and it's not in
gcc search paths. It cannot go into CPPFLAGS because those are used
for windres invocations, and windres errors out with non-cpp flags.
- Add -DMINGW_HAS_SECURE_API to all flags to fix a problem with the
mingw headers in crossdev.
- Add -lpthread to a default LIBS env var so that it's often linked last
against any libraries that may need it, at least for autoconf.
- Set the PKG_CONFIG env var to the path of the built pkg-config binary,
not exactly sure why this was necessary.
- Overhaul environment variable saving/restoring for set_host_env() so
that more variables are covered and have good host defaults.
- Add the dlfcn-win32 for mingw for dependencies that need -ldl.
- Add some MSys2 patches for fontconfig.
- Use a sed script to fix the native tools compilation when cross
compiling openal.
- Replace the fedora glib patches for mingw with MSys2 ones for the
newer glib.
- Add --with-threads=posix --disable-libelf to glib DIST_ARGS.
Update the po files with the transifex client and do a msgmerge.
Replace cmake/FindGettext.cmake with the current version, and fix a bug
in it that would not allow files with multiple periods such as
zh_TW.Big5.po. Also disable msgmerge in GETTEXT_CREATE_TRANSLATIONS
otherwise it would create too many very spammy commits.
Replace language list in po/wxvbam/CMakeLists.txt (where the .pot and
.po files are) with a list made with file(GLOB ...), so that all the new
languages are pulled in.
- Add the cross root from the mingw-w64 mac brew to the cmake toolchain
files.
- Remove strerror_r/strerror_s from ConfigManager.cpp because the
mingw-w64 brew does not support strerror_s for some reason.
- Strip the vbam executable from the builder script in the build_project
phase.
- Change the bzip2 URL to the github mirror because the bzip.org domain
expired.
- Add libuuid as it's required by the new fontconfig, use the mingw
version for mingw builds, for mingw also set UUID_LIBS to
'-luuid_mingw -luuid' in mingw.sh for fontconfig, the mingw version
is called uuid_mingw because uuid is a core win32 library.
- Lower glib version to 2.57.2 stable.
- Update wxwidgets version to current master sha.
- Fix a bug in flex-2.5.3 post_build where it tries to build flex
current but flex has been removed, and it was just rebuilding 2.5.3.
- Fix "aggressive" relocation and the relocation of .l[ao] and .pc files
in install_dist to ignore /usr/local, and only match /usr.
- Add a "project" pre_build and post_build hooks.
- Add getopt to host-only dists in mingw-cross.sh.
- Use perl instead of readlink -f to get the absolute path of the cmake
toolchain files in mingw-cross.sh, as readlink -f is linux-only.
- In mingw-cross.sh, replace the glib post_build to rebuild
gettext-target instead of gettext --without-included-glib.
- Add overridable functions set_host_env_hook and unset_host_env_hook in
mingw.sh to override in other scripts, in this case mac-cross-builder.
- Update mingw glib patches to current fedora versions.
- Add tools/win/mac-cross-builder script to build mingw windows binaries
on mac, it borrows some necessary parts from the mac native builder
for host dists, and inherits from mingw-cross.sh.
TODO: currently the resulting mac-built binary segfaults due to gcc
8.2.0, just as the msys2-built binary does, this is a separate issue.
Update mingw cmake toolchain files to work-around a bug in cmake where
find_program() would return the current working directory instead of the
executable path if CMAKE_C_COMPILER and related are passed on the
command line.
Fix $CC/$CC_ORIG and $CXX/$CXX_ORIG handling for the core and
mingw-cross (_ORIG is without ccache.)
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.
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]`.
Run just one `git tag` command instead of two (with tags and refs) and
break it into the form [tag0, ref0, tag1, ref1, ...]. Iterate over the
list with two counters for tag and ref.
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".
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.
