When brlcad 7.18.4 is built, it will link to /usr/lib64/itk3.4 but will fail to find the library libitk3.4.so from that directory. Don't know if the problem is considered being in brlcad or itk, so for the time being I name both of them. Developers will point their fingers in the desired direction... See my 'dirty' work-around below. Reproducible: Always Steps to Reproduce: 1. emerge media-gfx/brlcad-7.18.4 2. open terminal window 3. run mged 4. Read error messsage Actual Results: user$ mged mged: error while loading shared libraries: libitk3.4.so: cannot open shared object file: No such file or directory root# locate libitk3.4.so /usr/lib64/itk3.4/libitk3.4.so root# qfile /usr/lib64/itk3.4/libitk3.4.so dev-tcltk/itk (/usr/lib64/itk3.4/libitk3.4.so) root# eix -I dev-tcltk/itk [I] dev-tcltk/itk Available versions: 3.4_pre20090417 ~3.4_pre20090417-r1 3.4.1 ~4.0.0 ~4.0.1 {test} Installed versions: 3.4.1(05:24:01 PM 04/15/2015)(-test) Homepage: http://incrtcl.sourceforge.net/ Description: Object Oriented Enhancements for Tcl/Tk Let's use brlcad's built-in diagnose utility... user$ brlcad-config --cflags -I/usr/brlcad/include/brlcad -I/usr/brlcad/include -DBRLCADBUILD=1 -O2 -march=athlon64 -pipe -fno-strict-aliasing -fno-common -fexceptions -w user$ brlcad-config --ldflags -L/usr/brlcad/lib64 -Wl,-O1 -Wl,--as-needed -L/usr/lib64/itcl3.4 -L/usr/lib64/itk3.4 -L/usr/local/lib64 -L/usr/local/lib -pipe -fno-strict-aliasing -fno-common -fexceptions -w Obviously, brlcad as installed by default looks for libraries in /usr/lib64/itk3.4 but fails to find it. Apparently it also looks in /usr/lib64/ because if I do the following 'dirty' workaround, it will work: root# cd /usr/lib64 root# ln -s itk3.4/libitk3.4.so . user$ mged #And mged starts as expected. As I said, a dirty work-around, but it could/should help to pin-point the actual problem. Expected Results: mged should find the library and start execution without root having to create a local symlink in a non-standard way. root# emerge --info Portage 2.2.18 (python 2.7.9-final-0,

We need to either get the newer versions from sci overlay here (they will use :8.5 slot for tcl/tk) or this be treecleaned and push people to rely on sci overlay (as it seems this ebuild is really outdated compared with the one in overlay)
The sci overlay version of brl-cad is dependant on tcl/tk 8.5. This, for me, created a circular dependency problem where many packages om the system wanted tcl/tk 8.6 and brl-cad wanted 8.5 and tcl/tk doesn't slot. What I found was that brl-cad sources have a bundled tcl implementation that can be enabled at build time. I added the following to src_configure(): mycmakeargs+=( -DBRLCAD_ITCL=BUNDLED ) This goes just before the call to cmake-utils_src_configure in src_configure(). I was then able to remove the version lock on dev-lang/tcl and dev-lang/tk in $DEPEND. Obaviously, I did this from brlcad-9999.ebuild in my own custom overlay. YMMV
