Cannot cross compile guile 1.8.3 on Ubuntu

Cannot cross compile guile 1.8.3 on Ubuntu

[Igor Chudov]

I am on a 64bit Ubuntu Hardy installation. I am trying to build Guile
1.8.3 but to build a 32 version thereof. (cross compile). 

So I did

   ./configure --host=i386

but this seems to have no effect and builds a x86_64 version of guilt,
which is NOT what I want. 

Any idea how I can cross compile and build a 32 bit version on a 64
bit platform Ubuntu Hardy?

thanks

I haven't actually done this, but try:

  CC='gcc -m32' ./configure

Also, as long as you're compiling from source, perhaps you should use
the newest release :)

If I do this, then I get in trouble with libtool, which still demands
that I link against 64 bit libraries:

Hello,

I suppose the problem is that /usr/lib/libgmp.so is 64-bit ELF.

Assuming the 32-bit version is under /usr/lib32, you can try something
like this:

  CC="gcc -m32" LDFLAGS="-L/usr/lib32" ./configure

Hope this helps,
Ludo'.

Yep.

And the real issue is that libtool finds the 64 bit version and forces
me to link against it.

Does not work:

Can you post the exact linker invocation, the one with "libtool
--mode=link" and the one with "gcc -shared" that follows?

Thanks,
Ludo'.
