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

[Christian Jullien]

Antoni,

 

If it helps, I maintain https://sourceforge.net/projects/wintcc/

Which easily builds a tcc multi-arch standalone archive for Windows.

It bootstraps tcc from Cygwin gcc and finally generates tcc buit by tcc Windows build (i.e. a reproducible build).

 

It contains only a Makefile you just have to drop on win32 tcc directory.

 

The generated dll contains in this case tcc_relocate you were looking for.

 

It can also generate small zip and tar.gz you can then deploy on any Windows machine wo. C compiler.

 

C.

Hi,

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,

Antoni Nowinowski

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?

No.

libtcc_test.c is there just fine:

% ls -l tests/libtcc_test.c
