#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
