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.
Regards,
Daniel Campos Ramos

Changes:
netgen (6.2.2606+dfsg1-3) unstable; urgency=medium
.
* Team upload.
* debian/tests Depends: dpkg-dev (for dpkg-architecture). Closes: #1150068
* netgen Depends: libnglib-dev instead of libnglib-6.2t64
(>= ${binary:Version}). Tcl is not smart about shared libraries,
treating "libnglib.so" literally, and is ignorant of the ABI.
Closes: #1150173, #1125008.
* move debian/menu to netgen.menu
