#8880: Configured gcc not used for some build steps ------------------------------------+------------------------------------- Reporter: tibbe | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 7.9 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- The gcc passed to `./configure --with-gcc` isn't used for all gcc invocations, leadings to warnings (and potentially problems) on OS X where the default gcc is llvm. Here's an example, the call to `gcc -E` doesn't use my configure gcc, `/usr/local/bin/gcc-4.9`: {{{ sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.dyn_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.l_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.debug_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.thr_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.thr_debug_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.thr_l_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.debug_dyn_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.thr_dyn_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.thr_debug_dyn_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.l_dyn_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && sed -e 's|\\|/|g' -e 's| /$| \\|' -e "1s|\.o|\.thr_l_dyn_o|" -e "1s|^|rts/|" -e "1s|rts/|rts/dist/build/|" -e "1s|dist/build/dist/build|dist/build|g" -e "s|/Users/tibbe/src/ghc/||g" rts/dist/build/.depend-v-dyn-l-debug-thr- thr_debug-thr_l-debug_dyn-thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.tmp && true gcc -E -m64 -DPROFILING -DTHREADED_RTS -DDEBUG -Irts/dist/build -m64 -fno-stack-protector -Wall -Wextra -Wstrict-prototypes -Wmissing- prototypes -Wmissing-declarations -Winline -Waggregate-return -Wpointer- arith -Wmissing-noreturn -Wnested-externs -Wredundant-decls -Iincludes -Iincludes/dist -Iincludes/dist-derivedconstants/header -Iincludes/dist- ghcconstants/header -Irts -Irts/dist/build -DCOMPILING_RTS -fno-strict- aliasing -fno-common -DDTRACE -O2 -fomit-frame-pointer -DRtsWay=\"rts_v\" -Wno-strict-prototypes -MM -x c rts/WSDeque.c -MF rts/dist/build/.depend-v-dyn-l-debug-thr-thr_debug-thr_l-debug_dyn- thr_dyn-thr_debug_dyn-l_dyn-thr_l_dyn.c_asm.bit no checking for sigaction...
