Tests fails with new glibc

Hi, the test section fro one of 'my' packages fails since the new glibc is active: [ 502s] [----------] 2 tests from SharedLibrary [ 502s] [ RUN ] SharedLibrary.Enumerations [ 502s] [ OK ] SharedLibrary.Enumerations (0 ms) [ 502s] [ RUN ] SharedLibrary.Basic [ 502s] E0926 16:45:19.856614 SharedLibrary.cpp:97] dlopen(libdl.so) failed: Error libdl.so: cannot open shared object file: No such file or directory [ 502s] unknown file: Failure [ 502s] Unknown C++ exception thrown in the test body. [ 502s] [ FAILED ] SharedLibrary.Basic (0 ms) was this libdl moved out? (sry, just packaging, but not programming C++) Thanks Axel
