Ok, this seems to be a bit more complicated as the linker settings have to be explicitly set in the ghc source code directly. I have tried building hscolour manually which initially works but eventually fails with: Language/Haskell/HsColour.hs:94:55: Warning: Tab character [ 1 of 16] Compiling Language.Haskell.HsColour.General ( Language/Haskell/HsColour/General.hs, dist-ghc/build/Language/Haskell/HsColour/General.p_o ) /usr/bin/ld: --relax and -r may not be used together collect2: error: ld returned 1 exit status make: *** [build-ghc-stamp] Error 1 /usr/share/cdbs/1/class/hlibrary.mk:147: recipe for target 'build-ghc-stamp' failed dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2 Full build log here [1]. Thus, we have to make sure that ghc does not just set "-Wl,-no-relax" when building itself but also when building any other Haskell sources. Or, alternatively, we could try to convince the gcc/binutils developers to fix the behavior of gcc/binutils when "-Wl,-r" are set. Apparently, this could be interpreted as a bug in gcc which actually sets "-no-relax" when "-r" is passed but not when "-Wl,-r" is passed. qemu is affected by the same problem, see [2]. Anyone on the Debian sparc mailing list with an idea?
