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?
Cheers,
Adrian
