Dear all, We use matplotlib with Tkinter support. Until foss/2018a that worked just fine, but with foss/2018b it causes a module named LibUUID to be loaded. That library breaks a lot of programs, for example it causes Emacs to crash. It also causes errors like this from the MPI stack:
[x049.nifl.fysik.dtu.dk:12411] mca_base_component_repository_open: unable to open mca_mtl_psm: /home/modules/software/LibUUID/1.0.3-GCCcore-7.3.0/lib/libuuid.so.1: version `UUID_1.0' not found (required by /lib64/libpsm_infinipath.so.1) (ignored) I don’t know why this library is being loaded by X11/20180604-GCCcore-7.3.0 but not by X11/20180131-GCCcore-6.4.0 Somehow, I guess the underlying real problem is that EasyBuild relies on LD_LIBRARY_PATH to find shared libraries, instead of compiling with -Wl,-rpath=XXX. It will invariably cause breakage like this, where one module points to a folder containing a library with the same name as another program expects to find elsewhere. But that may be very difficult to fix, getting rid of LibUUID might be a good start. :-) Best regards Jakob -- Jakob Schiøtz, professor, Ph.D. Department of Physics Technical University of Denmark DK-2800 Kongens Lyngby, Denmark http://www.fysik.dtu.dk/~schiotz/
