HI, im working with CW 9 for Mac on MacOSX. Im creating a static C++
library. I can compile it without any problems. Then i bring it into
another project, and use a few of its classes. It compiles fine. But i
get a few undefined symbols, that icannot seem to resolve. My settings
are the same in both projects. What should i look at to gget this to
link correctly.

thanks

Alex

Look for inlined functions, look for static functions, look for name
mangling problems. (probably it is name mangling) be sure you aren't
mixing any C and C++ files.

Are you using C++ templates?

Also, sometimes singleton-style classes will not get brought
in by the CW linker unless you make an explicit reference to
the object from a file which is definitely included. Usually I
set aside a section of my application startup code to point to
static singleton members so the linker will include them.
