Not reproducible with 1.3 (previous version). It affects me, too. Think this is a bug affecting many people. Created attachment 218627 [details]
patch that fixes the problem
The displayed error does not come from the dlopen call but from the last dlsym call in the icd loader.
Including a patch that solves the problem.
The problem was caused by the change from libltdl to libdl in version 1.4. Therefore, the dependency on libltdl.so in the Makefile is actually superfluous.
