Thin archives contain pathnames pointing to the object files instead of
full copies of the object files. This significantly reduces the disk
usage when building Dolphin.

A similar change was implemented in the Linux kernel v4.8:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a5967db9af51a84f5e181600954714a9e4c69f1f
We have to decide if we want to link to
libGL.so -- legacy
libOpenGL.so -- GLVND
As we use xxxGetProcAddress, we don't care about feature
levels of the linked library, so we're very fine with the
new way.
Allows us to bring includes and relevant libraries into scope by explicitly declaring linkage against the target
as opposed to using a variable. Also removes the dumping of OProfile includes into the top-level directory.
We already use a custom CMakeLists file for xxhash, so we can just make it's headers
public as part of its target interface.
This way, only libraries that link in the xxhash target will see its headers, as opposed
to every target under the top-level directory.
Adjusts Common to use the ICONV_LIBRARIES variable directly and doesn't
append it to the LIBS variable.
After this, there's only one remaining usage where libraries are added
to the LIBS variable, after which it can be removed once the rest of
the targets are migrated off add_dolphin_library
The only place this library is needed (core) is already linked in the core target.
Also make the linkage private to create linkage failures if the dependency isn't
explicitly linked in elsewhere where it should be.
Reduces the dependency on the LIBS variable.
Makes our libraries explicitly link in which libraries they need.
This makes our dependencies explicit and removes the reliance on the
LIBS variable to contain the libraries that they need.
Both libusbhid (system library) and libhidapi (3rd party library)
provide a function called hid_init. Dolphin was being linked to both.
The WiimoteScannerHidapi constructor was calling hid_init without
arguments. libusbhid's hid_init expects one argument (a file path).
It was being called as if it was defined without arguments, which
resulted in a garbage path being passed in, and because of that,
the Qt GUI was failing to launch with the following error:
'dolphin-emu-qt2: @ : No such file or directory'
Use @Orphis's FindFFmpeg module from ppsspp:

From that commit:
> This new module should be able to handle both libraries in the regular
> paths and fallback to pkg-config.
> It is also able to find dynamic libraries, not just static libraries.
> It will generate imported targets with the name FFmpeg::<lib> that you

Stops CMake from saying "BlueZ NOT found, disabling bluetooth support"
on other OSes. Windows, macOS, and Android support Bluetooth using other
libraries. I'm not sure if non-Linux, non-Android Unices (like FreeBSD)
need another message?
This PR attempts to turn on `-fdiagnostics-color` by default when using
the CMake Ninja generator.
Ninja effectively turns off colored messages by not running subcommands
in a pseudo-terminal. The Ninja maintainers have decided that using
pseudo-terminals has more downsides than upsides, but have helpfully
taught Ninja itself how to parse and remove color codes if its parent
isn't a (pseudo-)terminal.
Colored messages make it easier to read warnings and error messages in a
large build log, and are pretty.
To use it, with a modern LLVM (3.9+), set your CMAKE_PREFIX_PATH
to point to the LLVM install folder or to a LLVM build folder.
We're linking ALL of LLVM libs since I don't really know which ones we need.
LTO will take care of sliming the binary size...
Fixes an issue where Dolphin's revision information could be incorrect
when:
1) CMake was run while HEAD was at commit A
2) HEAD was set to commit B, which didn't have differences from A
that would cause CMake to be re-run
This does not fix the issue with incorrect information about whether
Dolphin was built from a dirty working tree or not.
The built-in `configure_file` command correctly handles the case where
none of the variables change and scmrev.h doesn't need to be rebuilt.
This saves a full re-link of Dolphin any time CMake is re-run.
On macOS, we want them copied in the bundle directly, otherwise we will
install them later in the system folder.
Obviously not working for Windows, but that's not any different from before!
This is similar to add_definitions, but supports generator expressions.
It also has an optional argument to add only to Debug or Release
configurations.
This is an issue because CMAKE_SYSTEM_PROCESSOR is defined as the host
processor when not cross-compiling, and building for Win32 doesn't count
as cross-compiling.
Compilers are very picky and don't use PCH when they have been compiled
with different flags. I even got some ICE in MSVC, so removing them for now.
Modules are the solution.
CMake would have trouble with some configuration tests on FreeBSD (and
presumably other BSDs) due to installed libraries being in /usr/local, but
not being in the default search path. Adding these to the default search path
fixes mbedtls and portaudio not being found, and possibly more.
In newer versions of CMake, the variable is ON by default.
This generates imports like @rpath/libusb.dylib which the
packaging script doesn’t understand.
We don’t really need @rpath, so we can just disable it
at the global scope instead of fixing the script.
They are already disabled when the libraries can’t be found, this only
helps people who want to build without them despite having them
installed, for example to provide a package to someone else.
Based on ca0c2efe7a. Credits go to flacs.
However, unlike the original commit, hidapi does not completely replace
the current implementations, so we can still connect Wiimotes with 1+2
(without pairing).
Also, it is only used on Linux and OS X for now. This removes the
advantage of having only one implementation but there is no other
choice: using hidapi on Windows is currently impossible because
hid_write() is implemented in a way that won't work with Wiimotes.
Additionally:
* We now check for the device name in addition to the PID/VID so we can
support the Balance Board and maybe third-party Wiimotes too. This
doesn't achieve anything with the DolphinBar but it does with hidraw.
* Added a check to not connect to the same device more than once.
Let's stop pretending that we support Triforce emulation.
Keeping this code around just in case someone will make
major improvements in the future isn't really worth it.
I'm keeping the Triforce game INIs so users will know that
the compatibility rating for Triforce games is 1 star (broken).
On a case-sensitive filesystem, the "foundation" library can not be
found, as the framework starts with a capital "F". Because the
Foundation framework is required by other parts of the build, this
causes the build to fail.
Should help with future builds, too, as the upcoming APFS is
case-sensitive.
Most modern Unix environments use 64-bit off_t by default: OpenBSD,
FreeBSD, OS X, and Linux libc implementations such as Musl.
glibc is the lone exception; it can default to 32 bits but this is
configurable by setting _FILE_OFFSET_BITS.
Avoiding the stat64()/fstat64() interfaces is desirable because they
are nonstandard and not implemented on many systems (including
OpenBSD and FreeBSD), and using 64 bits for stat()/fstat() is either
the default or trivial to set up.
From wxWidgets master 81570ae070b35c9d52de47b1f14897f3ff1a66c7.
include/wx/defs.h -- __w64 warning disable patch by comex brought forward.
include/wx/msw/window.h -- added GetContentScaleFactor() which was not implemented on Windows but is necessary for wxBitmap scaling on Mac OS X so it needs to work to avoid #ifdef-ing the code.
src/gtk/window.cpp -- Modified DoSetClientSize() to direct call wxWindowGTK::DoSetSize() instead of using public wxWindowBase::SetSize() which now prevents derived classes (like wxAuiToolbar) intercepting the call and breaking it. This matches Windows which does NOT need to call DoSetSize internally. End result is this fixes Dolphin's debug tools toolbars on Linux.
src/osx/window_osx.cpp -- Same fix as for GTK since it has the same issue.
src/msw/radiobox.cpp -- Hacked to fix display in HiDPI (was clipping off end of text).
Updated CMakeLists for Linux and Mac OS X. Small code changes to Dolphin to fix debug error boxes, deprecation warnings, and retain previous UI behavior on Windows.
OS X uses a case insensitive filesystem by default: when I try to build,
a system header does #include <assert.h>, which picks up
Source/Core/Common/Assert.h. This only happens because CMakeLists adds
'${PROJECT_BINARY_DIR}/Source/Core/Common' as an include directory: in
an out-of-tree build, that directory contains no other source files, but
in an in-tree build PROJECT_BINARY_DIR is just the source root.
This is only used for scmrev.h. Change the include directory to
'${PROJECT_BINARY_DIR}/Source/Core' and the include to
"Common/scmrev.h", which is more consistent with normal headers anyway.
Our x86_64 recompilers don't support PIE and fail amazingly if enabled.
Disable it so package maintainers(!) or other randoms don't accidently enable it when we don't support it.
This PR installs an SVG icon to use as the main icon for dolphin in Linux
desktop environments (through the .desktop file) and removes the currently used
XPM icon. I've also added a 48x48 PNG for any desktops which don't support SVG
icons.
This has been the recommended way to ship application icons since forever
according to the Icon Theme Spec:
https://www.freedesktop.org/wiki/Specifications/icon-theme-spec/
This is also a prerequisite for dolphin appearing in the GNOME Software Centre
which does not support XPM icons.
- Change the path of the Sys folder to the executable's location
- Add LINUX_LOCAL_DEV flag to use relocatable version on Linux
- Add CMake definition for relocatable build
Currently only works on unix, but can be extended to other systems. Can
also be extended to do wiimotes.
Searches the Pipes folder for readable named pipes and creates a dolphin
input device out of them. Send controller inputs to the game by writing
to the file. Commands are described in Pipes.h.
miniupnpc.h provides MINIUPNPC_API_VERSION since 1.7 and we require 1.7
or later, so there is no reason to have version detection code for older
versions.
Adds a cmake module to correctly discover OProfile and adjusts the
corresponding CMakeLists to make use of it. Additionally removes
linking against the bfd library when compiling with OProfile because
Dolphin does not use it.
Dolphin uses threads, but never actually pulled them it. Normally
some library we depend on would pull threads in, but there are
potential builds that forget to pull in threads.
Not deleted, because it's the only option for some other operating
systems such as FreeBSD or any other slightly exotic operating
system someone might try and run dolphin on.
LIBAV_LDFLAGS has -L, LIBAV_LIBRARIES is just the names of the
I think this is not necessary for other dependencies because they
consist of a single library and go through a different path (check_lib)
that provides the full path to it. e.g. from my CMakeCache.txt:
ICONV_LIBRARIES:FILEPATH=/usr/lib/libiconv.dylib (good)
LIBAV_LIBRARIES:INTERNAL=avcodec;avformat;swscale;avutil (bad)
...by telling CMake to use -isystem for the static wx include directory.
AFAICT, this is already done by CMake's FindwxWidgets script in the
shared case.
The changes I intend to make are:
- supporting IPv6 by rebasing on https://github.com/freeminer/enet
- adding custom code for quick resending
Even if I manage to get the latter upstream (which I'd like to wait for
some testing before attempting), I don't know what the original author
might do with the former, so...
Leave an option to use it for the sake of Linux distros - this means any
changes must stay protocol compatible, and Dolphin must work around any
API incompatibilities (e.g. for IPv6).
This fixes detection of at least libenet via pkg-config, and I think
libpng via pkg-config pulseaudio via direct detection.
Also remove the NOT APPLE from the shared libenet check, because there's
no reason for it.
If we don't unset it, all the CMake checks will run with PortAudio
in the library list. This didn't affect those who had PortAudio,
but for select Debian systems without it, it breaks everything.
Since libcommon.a is also the last library to be linked, this has the
totally hacky but useful side-effect that it doesn't require people to
modify CMake files for temporarily adding VTune code to other Dolphin
libraries.
Changing PATH basically screws everything up, and while the attempt to
avoid MacPorts copies of system libraries was well-intentioned, it made
the OS X buildbot unable to pick up ffmpeg and libusb.
It's sufficient to put /usr first to make sure we use the system copies
of duplicated libraries.
