#5337: mkRtsOptionsLevelObj should respect -optc standard headers -------------------------------+-------------------------------------------- Reporter: gnezdo | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.0.4 | Keywords: Testcase: | Blockedby: Os: Linux | Blocking: Architecture: x86_64 (amd64) | Failure: None/Unknown -------------------------------+-------------------------------------------- Our fancy compilation environment does not keep the standard C headers always in the same place. We always invoke gcc with --sysroot. Then we pass the same flag to ghc with -optc--sysroot=blah.
This works most of the time until I also do ghc -rtsopts. In that case GHC will try to build a small generated object file with a limited command line that fails to include -optc flags. That leads to failure: *** C Compiler: gcc -c /tmp/ghc15472_0/ghc15472_0.c -o /tmp/ghc15472_0/ghc15472_0.o -Ilib/ghc-7.0.4/include -fno-stack-protector In file included from /tmp/ghc15472_0/ghc15472_0.c:1:0: In file included from lib/ghc-7.0.4/include/Rts.h:23:0: lib/ghc-7.0.4/include/Stg.h:62:10: fatal error: 'math.h' file not found #include <math.h> ^ 1 error generated. This seems trivially easy to fix with the attached patch. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5337> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
