Problems compiling TCC on OS X

Question

Has anyone successfully compiled TCC on OS X?

From what I know it should be possible but when I run make I get the following error:

$ make
gcc -o tcc tcc.c -DTCC_TARGET_I386 -O2 -g -Wall -fno-strict-aliasing -mpreferred-stack-                boundary=2 -march=i386 -falign-functions=0 -Wno-pointer-sign -Wno-sign-compare -D_FORTIFY_SOURCE=0 -lm -ldl
tcc.c:1: error: CPU you selected does not support x86-64 instruction set
tcc.c:1: error: CPU you selected does not support x86-64 instruction set
tcc.c:1: error: -mpreferred-stack-boundary=2 is not between 4 and 12
make: *** [tcc] Error 1

./configure runs fine and gives the following output:

$ ./configure

I'm pretty sure the issue is something simple, but I haven't compiled enough programs on OS X to be aware of the pratfalls...

The primary purpose for installing TCC was to get libtcc so I could start experimenting with dynamic code generation from Ruby (in case that makes a difference :-p)

Thanks!

Answer 1

I have just spent some serious time trying to make tcc run on osx. I have included several fixes, including the one from the answer above, and now they are all in the development repository at http://repo.or.cz/w/tinycc.git. Building, some tests and all examples should work.

I am not sure if you are aware, but http://bellard.org/tcc/ site that belongs to Fabrice Bellard who started this project, is not being updated very regularly. Mostly because there are not many 'official' tcc releases. tcc is one of those projects that mostly lives off of live sources and updates. So if you want to give this another try, please go to http://repo.or.cz/w/tinycc.git and get the 'mob' branch (not 'master'). Please see http://repo.or.cz/w/tinycc.git for details, and do join the mailing list to get involved.

Answer 2

I'll consolidate my comments now.

There seem to be several issues.

1. There has been a change in the naming scheme for the x86 register access as of Mac OS 10.5. See Access EIP and EBP via ucontext on OS X. This will require hacking the source until the maintainer can be convinced to support Mac OS X.
2. The executable formats supported by tcc do not overlap with those that Mac OS X will run natively. However, XBinary may address this. (I didn't find either a fink package or a MacPorts package, however and don't have it installed yet. Not sure that I will--this is deep magic, and could in theory do very bad things indeed.) Ah... this was already on SO too: Possibility of loading/executing ELF files on OSX.
