问题
I'm going through a Makefile. Found this interesting bit of code, LIBS = -l:libevent.a. Was digging through gcc documentation but didn't find anything relevant. Does anyone know what it means?
回答1:
It instructs the linker to find and link a library with the exact name libevent.a,
in the specified (-Ldir) or default linker search directories, as opposed to
the usual convention whereby -lfoo instructs the linker to find and link either libfoo.so (shared library)
or libfoo.a (static library), preferring libfoo.so if both are found in the same search directory.
See the documentation of -lnamespec | --library=namespec in the linker manual
