Re: error: cannot find -lXpm. But libXpm is in /usr/lib

Hi,

Assuming your system is a linux machine, the linker typically looks
for libraries with a suffix of either ".a" or ".so". Notice that your
libraries are not named in that fashion; there's versioning suffixes
*after* the ".so".

I've recently encountered this situation on an Ubuntu system, and I
don't understand the reasoning behind such a naming convention . Given
that, I'm not sure what the "proper" solution is. The man page for ld
indicates you might be able to replace "-lXpm" with "-l:libXpm.so.
4" (note the colon). Alternatively, creating a symlink named "libXpm.
4.so", pointing to "libXpm.so.4" might do the trick, but this likely
subverts the intent behind such naming, and may not be generally
advised.
