Hello, I stumbled in an dynamin linking issue while using gschem (circuit schematic editor frmo gEDA-gaf) built with guile 1.8.8 and libtool 2.4.2 on OX 10.7 using MacPorts [2].
The issue is due to the difference between guile's dynamic-link [1] default paths and MacPorts' prefix whose default value is /opt/local , while investigating how I could make guile look for libraries in the right path I've been told on #guile Freenode channel that 1.8.x behavior was totally dependent on libtool's, specifically libltdl. I then searched libtool's configure script for options about setting the dl search path, I wasn't able to find it so I manually patched lines sys_lib_dlsearch_path_spec='/usr/local/lib /lib /usr/lib' to sys_lib_dlsearch_path_spec='/macports/specific/paths /usr/local/lib /lib /usr/lib' in darwin* sections of configure script, there were four occurencies. Is it correct to patch the search path for non-standard paths? If so is there a configure flag for setting the search path? If not what's the correct approach? In the same darwin* sections there is the line shlibpath_var=DYLD_LIBRARY_PATH that suggested me the env variable would actually affetc the configuring, but it didn't happen, i.e. with DYLD_LIBRARY_PATH set to /opt/local/lib in the environment and/or passed to the configure script (tried all three combinations) the search path didn't include /opt/local/lib . Why is this? As reference you can see the actual trace of the issue and the patch at [3].
