I was trying to rebuild wxGTK-2.8.12.1-r2 in order to change a USE flag (specifically, to remove the "gstreamer" flag because then I can get rid of gstreamer:0.10 entirely). I encountered an odd build error: ----- x86_64-pc-linux-gnu-g++ -m32 -c -o basedll_threadpsx.o -D__WXGTK__ -DWXBUILDING -I/var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/src/regex -DwxUSE_GUI=0 -DWXMAKINGDLL_BASE -DwxUSE_BASE=1 -fPIC -DPIC -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -I/var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1-abi_x86_32.x86/lib/wx/include/gtk2-unicode-release-2.8 -I/var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/include -pthread -I/usr/include/gtk-2.0 -I/usr/lib32/gtk-2.0/include -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/libdrm -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/glib-2.0 -I/usr/lib32/glib-2.0/include -pthread -Wall -Wundef -Wno-ctor-dtor-privacy -O2 -fno-strict-aliasing -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -march=native -O2 -finline-functions -ftracer -pipe -flto -fuse-linker-plugin -ffat-lto-objects -fno-strict-aliasing /var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/src/unix/threadpsx.cpp x86_64-pc-linux-gnu-g++ -m32 -c -o basedll_event.o -D__WXGTK__ -DWXBUILDING -I/var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/src/regex -DwxUSE_GUI=0 -DWXMAKINGDLL_BASE -DwxUSE_BASE=1 -fPIC -DPIC -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -I/var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1-abi_x86_32.x86/lib/wx/include/gtk2-unicode-release-2.8 -I/var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/include -pthread -I/usr/include/gtk-2.0 -I/usr/lib32/gtk-2.0/include -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/libdrm -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/glib-2.0 -I/usr/lib32/glib-2.0/include -pthread -Wall -Wundef -Wno-ctor-dtor-privacy -O2 -fno-strict-aliasing -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -march=native -O2 -finline-functions -ftracer -pipe -flto -fuse-linker-plugin -ffat-lto-objects -fno-strict-aliasing /var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/src/common/event.cpp /var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/src/unix/threadpsx.cpp:51:24: fatal error: thread.h: No such file or directory compilation terminated. make: *** [Makefile:21662: basedll_threadpsx.o] Error 1 ------ I examined that file /var/tmp/portage/x11-libs/wxGTK-2.8.12.1-r2/work/wxPython-src-2.8.12.1/src/unix/threadpsx.cpp and this appears to be the problematic section: ----- #include <stdio.h> #include <unistd.h> #include <pthread.h> #include <errno.h> #include <time.h> #ifdef HAVE_SCHED_H #include <sched.h> #endif #ifdef HAVE_THR_SETCONCURRENCY #include <thread.h> #endif ----- My standard /usr/include directories have a pthread.h, but not a thread.h. Some /usr/include subdirectories have a "thread.h" but they're for things like libevent and llvm - not what wxGTK is seeking. I discovered a workaround - by setting the PCH USE flag (precompiled headers), it builds successfully. However, I still can't understand 1) why I was ever able to build without PCH in the first place in the past, and 2) where the past thread.h file came from (previous version of glibc??), what provided it, and why it's gone. As it stands now, PCH is now a mandatory USE flag for this package and no longer optional. I use Audacity and other packages that depend on wxGTK:2.8 so removing it wasn't an option for me.

Created attachment 476534 [details] Failed build log of x11-libs/wxGTK-2.8.12.1-r1
one must try -std=c++0x
What for do you guys need wxGTK:2.8 at all over 3.0 anymore?
Audacity stable.
wxGTK:2.8 is p.masked for removal (bug 661284), thus this bug is now obsolete (and audacity stable uses wxGTK:3.0 by now)
