Created attachment 476516 [details, diff] Makefile patch When attempting to build app-emulation/playonlinux-4.2.11, I get the following error: gcc -O2 -pipe -march=haswell -Wl,-O1 -Wl,--as-needed -Wl,-z,now -Wl,-z,relro -lGL -lX11 ./src/check_direct_rendering.c -o ./bin/playonlinux-check_dd /var/tmp/portage/app-emulation/playonlinux-4.2.11/temp/ccEoJYO5.o: In function `main': check_direct_rendering.c:(.text.startup+0x28): undefined reference to `XOpenDisplay' check_direct_rendering.c:(.text.startup+0xe4): undefined reference to `glXChooseVisual' check_direct_rendering.c:(.text.startup+0x102): undefined reference to `glXCreateContext' check_direct_rendering.c:(.text.startup+0x112): undefined reference to `glXIsDirect' check_direct_rendering.c:(.text.startup+0x169): undefined reference to `XFree' check_direct_rendering.c:(.text.startup+0x182): undefined reference to `glXChooseVisual' The older app-emulation/4.2.10-r1 builds fine. I have traced the problem to the upstream Makefile including "-lGL -lX11" in CFLAGS, causing them to appear before the source file and get filtered by "-Wl,--as-needed" in LDFLAGS (Gentoo default). I have submitted a PR on the upstream Github to fix the issue, but in the meantime this patch fixes the issue.
fixed in .12
