#8498: gcc hardcoded in build scripts! (ignores the --with-gcc= flag in configure) ------------------------------------+--------------------------------- Reporter: carter | Owner: Type: bug | Status: new Priority: high | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Keywords: | Operating System: MacOS X Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+--------------------------------- NB: this may be a dupe of another issue, but reporting is separately for now i'm on OS X 10.8 (mountain lion) with xcode 5, ghc comit 23fb7f3b7987d7b3fa445e54680a8a00a37e714d, I've got a gcc-4.8 installed, though gcc in my path is actually clang (as is typical for xcode 5), so I configured as {{{ ./configure --with-gcc=gcc-4.8 }}} and then I noticed as i'm building, some warnings that mean clang is being called rather than gcc! heres a relevant snippet of the build transcript {{{ cp" utils/hsc2hs/template-hsc.h inplace/lib/template-hsc.h "/usr/bin/ghc" -hisuf hi -osuf o -hcsuf hc -static -H64m -O -fasm -package process -package containers -package-db libraries/bootstrapping.conf -i -iutils/deriveConstants/. -iutils/deriveConstants/dist/build -iutils/deriveConstants/dist/build/autogen -Iutils/deriveConstants/dist/build -Iutils/deriveConstants/dist/build/autogen -no-user-package-db -rtsopts -odir utils/deriveConstants/dist/build -hidir utils/deriveConstants/dist/build -stubdir utils/deriveConstants/dist/build -c utils/deriveConstants/./DeriveConstants.hs -o utils/deriveConstants/dist/build/DeriveConstants.o "inplace/bin/mkdirhier" utils/deriveConstants/dist/build/tmp//.
