Package: netgen Version: 6.2.2606+dfsg1-1 Severity: important Dear Maintainer,
With only netgen installed, the graphical interface does not start: $ netgen NETGEN-6.2.2606 ... Error in Tcl-Script: result = couldn't load file "libnggui.so": libnggui.so: cannot open shared object file: No such file or directory ng/ng.tcl loads the GUI library by its unversioned name: load libnggui[info sharedlibextension] gui In the Debian packaging that name exists only in libnglib-dev (debian/libnglib-dev.install: usr/lib/*/libnggui.so), while the runtime package libnglib-6.2t64 ships libnggui.so.6.2 and libnggui.so.6.2.2606. Installing libnglib-dev makes the GUI start, which is why it is easy to miss on a development machine. A possible correction is a Debian patch that loads the library by its SONAME, so no -dev symlink is needed at run time: - load libnggui[info sharedlibextension] gui + load libnggui[info sharedlibextension].6.2 gui Note that the netgen binary does not read ng/ng.tcl at run time: the Tcl sources are compiled into ng/onetcl.cpp, which is committed pre-generated in the source tree. The same change has to be made in ng/onetcl.cpp (or onetcl.cpp regenerated during the build), otherwise the patch has no effect. Steps to reproduce, in a clean debian:testing container: apt-get install netgen xvfb xauth xvfb-run -a netgen Found while packaging a stereo 3D version of netgen for Sparky Stereo OS, an edition of SparkyLinux.
