#11211: Please add initial platform support for sparc64 --------------------------------+---------------------------------------- Reporter: glaubitz | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Linux Architecture: Other | Type of failure: Building GHC failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: --------------------------------+---------------------------------------- Hello! I have successfully bootstrapped ghc for sparc64 on Debian unstable by cross-compiling it on amd64, then installing it manually into a build root and rebuild the Debian package. Unfortunately, the buildds can currently neither compile ghc itself nor any Haskell packages as gcc always passes "-relax" to the GNU linker which will fail as ghc passes "-Wl,-r" [1]: "/usr/bin/ghc" -hisuf hi -osuf o -hcsuf hc -static -H32m -O -lffi -optl- pthread -package-db libraries/bootstrapping.conf -this-package-key termi_6iVf4EBnOgfIaaOCLRs8jl -hide-all-packages -i -ilibraries/terminfo/. -ilibraries/terminfo/dist-boot/build -ilibraries/terminfo/dist- boot/build/autogen -Ilibraries/terminfo/dist-boot/build -Ilibraries/terminfo/dist-boot/build/autogen -Ilibraries/terminfo/. -optP-include -optPlibraries/terminfo/dist- boot/build/autogen/cabal_macros.h -package-key base_HQfYBxpPvuw8OunzQu6JGM -Wall -XHaskell2010 -no-user-package-db -rtsopts -odir libraries/terminfo/dist-boot/build -hidir libraries/terminfo/dist- boot/build -stubdir libraries/terminfo/dist-boot/build -c libraries/terminfo/./System/Console/Terminfo/Base.hs -o libraries/terminfo /dist-boot/build/System/Console/Terminfo/Base.o /usr/bin/ld: --relax and -r may not be used together collect2: error: ld returned 1 exit status make[3]: *** [libraries/terminfo/dist- boot/build/System/Console/Terminfo/Base.o] Error 1 libraries/terminfo/ghc.mk:3: recipe for target 'libraries/terminfo/dist- boot/build/System/Console/Terminfo/Base.o' failed This issue has already been fixed in ghc but that was for sparc only and not sparc64 [2]. Thus, in order to be able to apply the same fix from [2], ghc needs to add sparc64 to its list of known architectures (currently "sparc64" matches to "ArchUnknown" in aclocal.m4") and then extend the fix from [2] to match *both* sparc *and* sparc64 (please don't drop sparc here). In particular, I suggest adding sparc64 in the same way that Alpha, Mipseb and Mipsel were added [3], thus matching "sparc64" to "ArchSPARC64", then extending the if-clause from [4] to set "-Wl,-no-relax" for *both* ArchSPARC *and* ArchSPARC64. Thanks, Adrian
