Whats the difference of lib and libo?

Hello guys!

In UG, we have:

Code:

lib Build a statically-linked library

libo Build a statically-linked object file library

So what is the difference between lib and libo? Thanks very much!

Quick answer:

"lib" creates for example "libOpenFOAM.a", which can be linked as is it were a dynamic library: http://en.wikipedia.org/wiki/Static_library
"libo" essentially merges several "*.o" files into a single "*.o" file. Then you have to explicitly include the "libOpenFOAM.o" file by full name in the binary being built.
