Created attachment 506210 [details, diff] ebuild patch to correctly disable wxwidgets dependency in games-emulation/dolphin-9999 I noticed that due to several bugs, games-emulation/dolphin-9999 does not currently build. I understand it's a bit complicated with LLVM, but I believe there's a rather small bug in the ebuild itself and how it interprets USE Flags and passes parameters to cmake. Situation: I've been attempting to compile games-emulation/dolphin-99999 without wxwidgets, since the version of wxwidgets it relies upon (3.10) is not in the tree yet. However, when I attempt to build it with USE="-wxwidgets", I get the following in my build: ----- - Could NOT find wxWidgets: Found unsuitable version "3.0.2", but required is at least "3.1.0" (found -L/usr/lib64;-pthread;;;-lwx_gtk2u_core-3.0;-lwx_gtk2u_aui-3.0;-lwx_gtk2u_adv-3.0;-lwx_baseu-3.0) -- Using static wxWidgets from Externals CMake Error at CMakeLists.txt:755 (add_subdirectory): add_subdirectory given source "Externals/wxWidgets3" which is not an existing directory. ------ From looking at my build logs, I can see that portage is adding -DDISABLE_WX=ON to the cmake invocation: --- cmake --no-warn-unused-cli -C /var/tmp/portage/games-emulation/dolphin-9999/work/dolphin-9999_build/gentoo_common_config.cmake -G Unix Makefiles -DCMAKE_INSTALL_PREFIX=/usr -DUSE_SHARED_ENET=ON -DENCODE_FRAMEDUMPS=ON -DFASTLOG=OFF -DOPROFILING=OFF -DDISABLE_WX=ON --- In reading through the CMakeList.txt file in the work tree, I found the following: --- option(ENABLE_WX "Enable wxWidgets (Default)" ON) --- Imo, the DISABLE_WX=ON flag *should* disable the dependency, but I'm no cmake expert. In looking through the cmake.eclass documentation, and doing some experimentation, I believe the following patch should be applied to games-emulation/dolphin-9999 and games-emulation/dolphon-5.0 to get the desired behavior: --- --- /usr/portage/games-emulation/dolphin/dolphin-9999.ebuild 2017-02-28 14:50:50.000000000 -0500 +++ /usr/local/portage/local-fixes/games-emulation/dolphin/dolphin-9999.ebuild 2017-11-23 14:13:53.629758536 -0500 @@ -119,2 +119,3 @@ + # Remove ALL the bundled libraries, aside from: @@ -158,3 +159,3 @@ $( cmake-utils_use profile OPROFILING ) - $( cmake-utils_use_disable wxwidgets WX ) + $( cmake-utils_use_enable wxwidgets WX ) $( cmake-utils_use_enable evdev EVDEV ) --- Initial testing on my configuration shows that it gets rid of the WX dependency, but it bombs out due to the other issues listed in bug 594940.
It seems that the WXWidgets frontend is being phased-out, which is why the dependency is set to a version that doesn't exist (even in git). Despite the error thrown, it actually _does_ build the WXWidgets frontend without further complaint. The actual flag should be -DENABLE_WX=OFF to only build the Qt5 frontend. Haven't built from the -9999 ebuild yet, but building straight from git requires the following extra packages: net-libs/mbedtls media-libs/libsfml dev-libs/hidapi I used "cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr -DENABLE_QT2=true -DDISABLE_WX=ON" and make didn't complain once. Built without any issues.
I think this can be closed since dolphin-wx has been removed: https://github.com/dolphin-emu/dolphin/commit/e22c5333ab50c3e84774ce831eaeba48bcea5901
Was handled in bug #598625. Thanks all! *** This bug has been marked as a duplicate of bug 598625 ***
