#9421: magic number mismatch when installing 32bit on 64bit machine -------------------------------------+------------------------------------- Reporter: | Owner: MikolajKonarski | Status: new Type: bug | Milestone: Priority: normal | Version: 7.8.3 Component: Compiler | Keywords: Resolution: | Architecture: x86_64 (amd64) Operating System: Linux | Difficulty: Unknown Type of failure: Installing | Blocked By: GHC failed | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by MikolajKonarski): Here is the trivial workaround (perhaps I should add it to the wiki somewhere and then close the ticket?): {{{ CFLAGS=-m32 ./configure --prefix=..... }}} Now I can compile many packages and the 32bit executables work (e.g., alex, happy). I still struggle with gtk2hs and I haven't tried beasts like yesod, etc, though. The command I use is {{{ cabal install --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc- option="-optl-m32" --ld-option="-melf_i386" }}} == Long story == The workaround is inspired by https://ghc.haskell.org/trac/ghc/ticket/8910 and http://www.haskell.org/pipermail/glasgow-haskell- users/2012-February/022014.html I had to install many -dev:i386 versions of libraries on my Ubuntu to make it work. The most problematic was libgmp-dev, since my Ubuntu only tolerates amd64 or i386 version of this lib at once (zlib1g-dev:i386 didn't have that problem). I ended up adding a hacky symlink instead of the -dev:i386 version: {{{ sudo ln -s /usr/lib/i386-linux-gnu/libgmp.so.10.0.2 /usr/lib/i386-linux- gnu/libgmp.so }}} == The remaining gtk2hs problem == This is probably a bug in gtk2hs-buildtools (I reinstalled them for 32bits with many extra flags, but no improvement), but I won't report it on gtk2hs issue tracker until I research a bit more. I try monstrosities like {{{ CFLAGS=-m32 cabal install glib -j1 --ghc-option="-optc-m32" --ghc- option="-opta-m32" --ghc-option="-optl-m32" --ld-option="-melf_i386" -v3 --gcc-option="-m32" --configure-option="CFLAGS=-m32" --ghc-option="-optl- Wl,-melf_i386" }}} but I'm still getting {{{ /tmp/glib-0.13.0.1-1099/glib-0.13.0.1/dist/setup/setup configure --verbose=3 --ghc --prefix=/mikolaj/.cabal --bindir=/mikolaj/.cabal/bin --libdir=/mikolaj/.cabal/lib --libsubdir=i386-linux- ghc-7.8.3/glib-0.13.0.1 --libexecdir=/mikolaj/.cabal/libexec --datadir=/mikolaj/.cabal/share --datasubdir=i386-linux-ghc-7.8.3/glib-0.13.0.1 --docdir=/mikolaj/.cabal/share/doc/i386-linux-ghc-7.8.3/glib-0.13.0.1 --htmldir=/mikolaj/.cabal/share/doc/i386-linux- ghc-7.8.3/glib-0.13.0.1/html --haddockdir=/mikolaj/.cabal/share/doc/i386-linux- ghc-7.8.3/glib-0.13.0.1/html --sysconfdir=/mikolaj/.cabal/etc --configure-option=CFLAGS=-m32 --user --flags=closure_signals --extra-prog-path=/mikolaj/.cabal/bin --constraint=utf8-string ==0.3.8 --constraint=text ==1.1.1.3 --constraint=containers ==0.5.5.1 --constraint=bytestring ==0.10.4.0 --constraint=base ==4.7.0.1 --disable-tests --disable-benchmarks --gcc-option=-m32 --ghc-option=-optc-m32 --ghc-option=-opta-m32 --ghc-option=-optl-m32 --ghc-option=-optl-Wl,-melf_i386 --ld- option=-melf_i386 [1 of 2] Compiling Gtk2HsSetup ( Gtk2HsSetup.hs, dist/setup- wrapper/Gtk2HsSetup.o ) /tmp/ghc1232_0/ghc1232_4.s: Assembler messages: /tmp/ghc1232_0/ghc1232_4.s:43:0: Error: invalid instruction suffix for `push' }}} I haven't looked inside the generated files nor inside the gtk2hs- buildtools yet. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9421#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

But here is a slightly different suggestion. Inside `$PREFIX/lib/ghc-7.8.3` you will find a file `settings`, which contains (among other things) the options that GHC passes to the C compiler, linker, etc. GHC reads this file at startup, so you can change any of these settings just by editing the file. Can you see if it is possible to effect all of your needed options like `-optc=-m32` via changes to this `settings` file? Those options should be respected by other Haskell tools like cabal and hsc2hs, so this may fix your other issues automatically. (If those tools do not respect these settings, it is probably a bug in those tools that should be fixed.) If it's not possible because you need (for example) a new setting `"assembler flags"`, it should be fairly easy to add such settings to this file. If the needed changes can be made through the `settings` file, then we won't need to modify GHC itself at all, and we can have the binary distribution `configure` script automatically detect that you are trying to install an x86 GHC on an x86_64 system, and modify the `settings` file accordingly. (By the way I'm a bit confused by your option `-optl-m32`, because my linker doesn't have a `-m32` option, only `-melf_i386`. Does that `-optl-m32` really do anything?) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9421#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I've updated the wiki page. Re anticipating setting for all possible systems, how would it hurt, if i386 GHC, whenever if detected that TARGET /= HOST, always kept setting something like {{{ --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc-option="-optl-m32" --ld-option="-melf_i386" }}} It's not x86_64 specific, at least, isn't it? As a default, it's less clean but more effective than the optimistic empty list of options. Thank you for the {{{lib/settings}}} suggestion.

I tried modifying the file manually and, at least initially, "-m32" for "C compiler flags" is necessary and sufficient for GHC alone. It apparently gets passed through to gcc when it does {{{-x assembler}}}, so we don't need "assembler flags" nor "-opta-m32". Also, "-optl-m32" is not needed at all, at least for simple packages. This is all very encouraging. However, I need to manually pass {{{--ld-option="-melf_i386"}}} to cabal, because the "ld flags" are ignored by cabal. I will investigate. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9421#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The old GHC 7.6.3 has no "ld flags" nor "Ld Linker flags" in the settings file, but it somehow produces "Ld Linker flags" in the {{{ghc --info}}} output and this is what cabal expects. However, GHC 7.8.3 has "ld flags" in the settings file and doesn't produce "Ld Linker flags" at all in {{{ghc --info}}}. This may be a bug or a half-done transition to another convention, but right now it fools the newest cabal. BTW, I can't probably specify "Ld Linker flags" manually in the settings file, because it's supposed to be a list of options, not a string, as the other options. Perhaps "ld flags" was intended to let people extend "Ld Linker flags" manually via the settings file? Anyway, it doesn't work right now. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9421#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
