Adding cruft to your filesystem when you could simply fix the makefile is a silly suggestion. Maintaining a site-specific patch to the Makefile temporarily until the project Makefile is changed is more work than just leaving the symlink in place until the project Makefile is changed. Peace...

More precisely: what is the difference between an .a and an .so library? I detailed this a few posts ago. .a is a static library, .so is a shared library. How on earth does -lpcap point to /usr/lib? -lpcap tells the linker to look in every directory in the library search path to find either libpcap.a or libpcap.so. This library lives in /usr/lib on most systems, but the simh makefile hard-coding that path (and hard-coding it to only find the static library) is a big mistake. It is, but why not just symlink it for the time being? Peace... Sridhar
