Have you named the symbol(s) correctly in the module? They should be
prefixed with "modulename_LTX_"?
Check with "nm -D":
000af960 D pcl_LTX_stp_module_data
000af944 D pcl_LTX_stp_module_version
(in this case, the module is pcl.la and pcl.so, and the symbols I ask
for with dlsym() are "stp_module_data" and "stp_module_version").
See libtool.info, node "Modules for libltdl". This had me stumped for
a while, until I found a typo in the module name part of the symbol!
HTH,
