I’ve built Slicer and then SlicerRT from source several times in the past. I followed the online instructions. In the same computer, I recently updated (via git pull) the Slicer and SlicerRT repositories to master, and then rebuilt from scratch. The build of Slicer works fine, and I can start Slic…

Ok, I managed to compile now. Still aborts when starting the ExternalBeamPlanning module. Even if I edit by hand the init.py file you mentioned.

[image] ferhue: Still aborts when starting the ExternalBeamPlanning module It’s perhaps time to run in a debugger. The mentioned hack addresses a locale problem in Python, it’s doubtful it would lead to a crash.

[image] chir.set: +locale.setlocale(locale.LC_ALL, locale.getdefaultlocale()) Update: With this hack, Slicer starts but files are badly read (NRRD, DICOM…). This fix yields a functional Slicer: locale.setlocale(locale.LC_ALL, "C.UTF-8") NOTE: this is just a temporary hack for my Linux bui…

I just came back from vacation. I’m planning on working on SlicerRT related stuff later this week, at least fixing the build error. Please note that I’ll not be able to address Mac specific stuff, but hopefully it won’t come up. Can you give me more information on how to reproduce the crash when en…

[image] cpinter: Can you give me more information on how to reproduce the crash when entering the EBP module? Thanks! Hi, thanks! The crash does not happen when entering the EBP module, but rather when loading it at startup. In my case, I just do: /opt/SlicerRT_bld/inner-build$ ./SlicerWit…

Thanks for the info. By setting LD_DEBUG variable on Linux, I found: 1724316: find library=libvtkIECTransformLogic.so [0]; searching 1724316: search path=/opt/SlicerRT_bld/inner-build/lib/Slicer-5.9/cli-modules/.:/opt/SlicerRT_bld/inner-build/lib/Slicer-5.9/qt-loadable-modules/.:/opt/SlicerRT_bl…

I just run the debugger (linux) with latest Slicer and SlicerRT and I got (when loading the EBP module at startup): (gdb) run Starting program: /home/davide/Development/Slicer/Slicer-SuperBuild-Debug/Slicer-build/bin/SlicerApp-realPython Exception <class ‘AttributeError’>: module ‘_thread’ has no …

Thanks for trying! Sorry, one question, how do you run gdb? I tried with gdb --args ./inner-build/SlicerWithSlicerRT --no-splash and then run, but I did not get extra info. (I could not figure out how to call gdb SlicerAppReal and at the same time initialize the SlicerRT part.) Just to see if …

for running the debbuger, you can use QtCreator as descrived in C++ debugging with Qt Creator — 3D Slicer documentation (but with latest Slicer I am having issues with both QtCreator 17 and QtCreator 14.0.2: debugger does not start) using gdb from terminal (from the inner Slicer-build folder): ./S…

SlicerRT built from source cannot start

Thanks! It may be due to loading the dependencies (especially IECTransformLogic). I have seen this, but since there is no working debug build for Slicer I cannot debug it currently.
