Re: problems during installation of XEmacs 21.0

Any Heiko> ideas how to test that? I recommend building a NON-shared personal version of libpng, then using --site-includes and --site-libraries to link with that. No runtime problems that way. Most external libraries have an option to be built non-shared. If you DO decide to link with a shared library, you can use the poorly named --site-runtime-libraries flag to specify the exact path to search at runtime. Under Linux, there may be some disagreement in different distributions about whether the RPATH baked into the executable overrides the system default in /etc/ld.so.conf. Martin
