Re: cross-compiling on 64 to 32-bit Linuxlocalhost/
You don't need to specify -m32 if you have a tool set prefixed with the cross tag. The reason for using -m32 is because the user wants to use his 64-bit gcc to compile 32-bit code, so he has to tell the compiler to switch to 32-bit mode also. (Incidentally, if you're running on Linux, might also be a good idea to tell the compiler you're running in a 32-bit environment by executing gcc with linux32). Another way to use your 64-bit gcc without special compiler flags is to create scripts, named with the cross prefix, in your bin directory that execute the compiler in 32-bit mode (and perhaps also executed by linux32). Then these tools will be preferred by Autoconf when you use --host=. Thanks for your answer John, In fact I believed autoconf could have done all the job for me: that is invoking 64bit gcc with -m32 after having detected there is no i686-pc-linux-gnu compiler available :) But maybe it's rare to be in this situation? I'm building a closed source shared library that only depends on libc which is why I don't really need a chroot environment. For now, to ease my coworkers life, I came up with a shell script that does a little analysis before invoking configure: based on uname and gcc --print-multi-lib, it creates several build directories like build/linux/i386 and/or build/linux/x86_64 and invokes configure from there with proper CC overrides. Regards, Gregory
Automake and AR
Automake somehow defines AR to 'ar'. I'm not sure where this comes from, but I do know that it's definitely not $host-ar, as I would expect. Is this an automake bug, or user error?

AM_PROG_AS
Using AM_PROG_AS seems to set AS to 'as' instead of $host-as. Is this another case of user error, or is this an automake bug?

And when cross-compiling, make check always fails with some cannot execute binary or so, so distcheck would always fail? NightStrike's package is very specialized: by default it will run on 64-bit Windows only, because it's part of the support package for MinGW64 (or so I assume). So, since the package already requires a cross compilation environment, it might as well also require an emulator to be able to execute tests for a successful distcheck. wine comes to mind for this, together with binfmt-support to automatically execute w32 binaries using wine. Correct. And 64-bit Wine actually works pretty well.

Well, for tools like ranlib which is optional and unneeded on many systems it is desirable that the build succeeds without it. If configure doesn't detect ar, you have a problem if you need it, and if you happen to additionally link against your in-tree static library using -L. -lfoo rather than recommended libfoo.a, then a missing ar might now even turn in a bad build, linking against a wrong installed libfoo. This thing is an option precisely because there is no one answer that is always correct. Cheers, Ralf
