Question

Good morning,

I’m trying to build luabind using bjam binaries and g++ (mingw).

Lua root is in ‘D:\Dev\lua-5.1.4\’,

*.a file here: ‘D:\Dev\lua-5.1.4\lib\libluadll.dll.a’

*.dll file here: ‘D:\Dev\lua-5.1.4\lib\luadll.dll’

All these *.o files were compiled well, but when it started linking it, something went wrong:

gcc.link.dll bin\gcc-mingw-4.4.1\debug\libluabindd.dll.a
d:/programms/codeblocks/mingw/bin/../lib/gcc/mingw32/4.4.1/../../../../mingw32/b
in/ld.exe: cannot find -llibluadll.dll.a

...failed updating 2 targets...

So, I renamed libluadll.dll.a into lua5.1, lua5.1.a, but it’s still prints the same error message.

Thanks, beforehand.

Answer 1

Firstly, -l{name} directive searches for lib{name}.dll and lib{name}.a. So, yours should be -llua, not -llibluadll.dll.a.

Secondly, are Lua libraries compiled with g++ too? Object files and libraries compiled by different compilers are incompatible in general.
