  • Btw. I should have mentioned before: You only need to add the *_DIR line if the library is not in one of the system paths. Libraries in system paths are always found - adding them to *_LIBS is enough.

Actually if the library is in the system path then it needs to be added to SYS_LIBS, not _LIBS.


That is correct, of course. My bad.

Note that for _LIBS, Make does the linker line extensions based on wildcard expressions in the file system (see RULES_TARGET in Base), which means that the linker line only gets extended correctly if the library with the specified name is found in the specified place. Having a typo in the _DIRS setting (or the library in a different location, like in .../lib64 instead of .../lib) may have that library not show up correctly in the linker command.

Libraries in _SYS_LIBS are added to the linker line without Make checking for their existence, assuming the linker will find them.

Glad you have it working.
~Ralph
