Building static libraries on Mac using CMake and GCC?

Question

Greetings all,

I have a static library which I later link with my application. My development environment is CMake, GCC (Linux, Mac), MinGW (Windows).

I can

The warnings from ranlib indicate that those object files contained no operational code. You need to review each corresponding source file to see whether the code it contains should be compiled on Mac. It may be that the code was ported elsewhere but the conditional compilation doesn't recognize Mac correctly.

It isn't a 'slam dunk' diagnosis; the missing symbols are clearly in two groups - those related to trnk and those related to crv - and the files are likewise in two groups (prefixed trnk and crv), but it could be that the files define different functions. So, I would go looking at the source files corresponding to the empty object files and see if you can see the missing functions (probably ignore the leading underscore on the reported missing symbol names). If those functions are defined in those files, then you have to look at the complaints from ranlib.

Occasionally, if you ran out of disk space at an inconvenient moment, you could have zero-size object files (which contain no symbols, therefore). In that case, simply remove the empty object files (and free up some space, but you must already have done that) and build again.
