So my AMD64 books have been burning a hole in my bookshelf for so long,
I finally went out and got a athlon 64 and installed fedora core 2. much
to my dismay, ghc does not seem to work out of the box.
I took the following steps.
; yum install gmp.i386 readline.i386
now a
rpm -U
of the ghc rpms works great.
ghci works properly, and ghc seems to almost work when compiling.
the expected happens when I try to compile directly.
;ghc Main.hs -o main
# ~/tmp/x-03 10:26PM [EMAIL

/usr/bin/ld: skipping incompatible /usr/lib/ghc-6.2.1/libHShaskell98.a when searching
for -lHShaskell98
/usr/bin/ld: cannot find -lHShaskell98
collect2: ld returned 1 exit status
however, what I expected to work, doesn't.
;ghc -optl-m32 -opta-m32 -optc-m32 Main.hs -o main
# ~/tmp/x-03 10:36PM [EMAIL
PROTECTED] 1
compilation IS NOT required
/usr/bin/ld: skipping incompatible /usr/lib64/libgmp.so when searching for -lgmp
/usr/bin/ld: skipping incompatible /usr/lib64/libgmp.a when searching for -lgmp
/usr/bin/ld: cannot find -lgmp
collect2: ld returned 1 exit status
everything seems to work perfectly however, if I take the gcc command
that ghc would have run (gotten via ghc -v) and simply replace
-lgmp with /usr/lib/libgmp.so.3
so, any idea what the problem is? in -m32 mode linux seems to get
everything else right, but it can't seem to find that gmp without help.
Also, it would be nice if ghc automatically passed -m32 when it was in
x86_64 mode and wanted to create i386 code, once this happens, (and the
gmp thing is worked out) then x86_64 should work perfectly when creating
i386 binaries and I can get started on what I really want to do, which
is create a native x86_64 ghc :)
It would also be quite important for ghc to support a -m32 flag itself,
so I can continue to create i386 and x86_64 builds from the same ghc
binary. but one problem at a time..
