Hi all,

I am currently trying to compile the test examples mem_image.cpp with code::blocks software and I get some undefined reference problems:

undefined reference to `__getreent'
undefined reference to `__errno'
undefined reference to `fseeko'
undefined reference to `ftello'
undefined reference to `getc_unlocked'

I was wondering if there was any compiler flag I have to add to code blocks mingw compiler to resolve them, but I can't find any lib in CodeBlocks/MinGW folder that solves the problem.

I tried to add the libpthread.a lib of my cygwin/lib folder, that solves the _getreent reference but not the other ones; moreover, I'm using libraw_r.a which is supposed to be thread_safe...

So I was wondering if anyone already built a LibRaw example with code::blocks and could help me

Just in case, I give you the complete log (main.cpp is the renamed file mem_image.cpp) :
