Re: [Tinycc-devel] tcc_relocate is missing in libtcc.dll

I'm sorry for my own stupidity. Both msvc and gcc implicitly generated i386 output, but I'm using x86_64 windows so the TCC_IS_NATIVE flag wasn't defined. That's why tcc_relocate wasn't exported. Sadly, I discovered this after few days of digging into the code.

Best wishes,

I can't say much about this as I'm not using Windows, but AFAICS
tcc_relocate isn't defined or declared different from (say)
tcc_compile_string or tcc_add_file, which I assume you're using as well.
So I would be surprised if one is exported but the other isn't.  Are you
100% sure the problem is libtcc.dll not exporting a function, and not
something like a missing declaration or the like?

libtcc_test.c is there just fine:
