Hi all, I've been trying to cross-compile X11 for ARM. Unfortunately, the build runs in the preprocessor phase for a very very long time when preprocessing Graphics/X11/Types.hsc Upon passing -v to hsc2hs I saw many steps like checking XK_abrevebelowdot `GreaterOrEqual` Unsigned 17039360 executing: /usr/bin/arm-linux-gnueabihf-gcc -c /home/vanessa/git-builds/junk/X11-1.9/dist-newstyle/build/arm-linux/ghc-8.6.3/X11-1.9/build/Graphics/X11/ExtraTypes/XorgDefault_hsc_test37988.c -o /home/vanessa/git-builds/junk/X11-1.9/dist-newstyle/build/arm-linux/ghc-8.6.3/X11-1.9/build/Graphics/X11/ExtraTypes/XorgDefault_hsc_test37988.o -marm -fno-stack-protector '-fuse-ld=gold' -Wl,-z,noexecstack '-D__GLASGOW_HASKELL__=806' '-Dlinux_BUILD_OS=1' '-Dx86_64_BUILD_ARCH=1' '-Dlinux_HOST_OS=1' '-Darm_HOST_ARCH=1' -Iinclude -I/home/vanessa/git-builds/junk/X11-1.9/dist-newstyle/build/arm-linux/ghc-8.6.3/X11-1.9/build/include -I/home/vanessa/git-builds/junk/X11-1.9/dist-newstyle/build/arm-linux/ghc-8.6.3/X11-1.9/build/autogen -I/home/vanessa/git-builds/junk/X11-1.9/dist-newstyle/build/arm-linux/ghc-8.6.3/X11-1.9/build/global-autogen -include /home/vanessa/git-builds/junk/X11-1.9/dist-newstyle/build/arm-linux/ghc-8.6.3/X11-1.9/build/autogen/cabal_macros.h -I/usr/local/lib/arm-linux-gnueabihf-ghc-8.6.3/base-4.12.0.0/include -I/usr/local/lib/arm-linux-gnueabihf-ghc-8.6.3/integer-gmp-1.0.2.0/include -I/usr/local/lib/arm-linux-gnueabihf-ghc-8.6.3/include result: False which I assume are necessary or at least progressing... Is there any way to speed this up? Is it a bug of some sort in hsc2hs or X11? Is there any hope in reporting upstream to the appropriate project (and what is the appropriate project in this case?)?
