c++ - What is *.o file?

Question

I'm compiling own project. And it halted by this error:

LINK||fatal error LNK1181: cannot open input file 'objwin eleasesrcluaindings.o'|

Compiling using Code::Blocks with VS 2005/2008 compiler under win7. There are also lot of another empty directories where *.o files are missing.

What do they do?

Answer 1

A file ending in .o is an object file. The compiler creates an object file for each source file, before linking them together, into the final executable.
