Cmake fails - picking up OCCT inside PrusaSlicer?

[BDL42]

Thought I would update my version of FreeCAD from git and have run into a snag. git pull was fine. I have built FreeCAD about 5 times now, without issues.

For some reason, cmake is pulling OCCT stuff out of PrusaSlicer, rather than out of my installed libraries. This is alpha sw and in it's own directory, with it's own occt libs. How do I get cmake to stop pulling stuff out of a "private alpha test sandbox" area?

Any insights would be appreciated. Thanks.

You should be able to explicitly set "OpenCASCADE_DIR" to the path you want it to use. Make sure you give it the path to the cMake file, not just the installation. e.g. "/usr/local/opencascade/lib/cmake/opencascade/" (or wherever yours is installed).

[BDL42]

How would one do this with cmake? It's apparently an argument to pass, but it's not clear (to me) how to do this.
I don't understand your instructions. occt-draw is in /usr/bin

[chennes]

Are you using the cMake GUI, or running on the command line?

[BDL42]

Using cli.

I am following the instructions on https://wiki.freecad.org/Compile_on_Linux in the section: Updating the source code

Code: Select all

The CMake system allows you to intelligently update the source code, and only recompile what has changed, making subsequent compilations faster.

Move to the location where the FreeCAD source code was first downloaded, and pull the new code:

cd freecad-source
git pull

Then move into the build directory where the code was compiled initially, and run cmake specifying the present directory (denoted by a dot); then trigger the re-compilation with make.

cd ../freecad-build
cmake .
make -j$(nproc --ignore=2)

A few months ago these instructions worked. 6 months ago, they worked as well.

About one month ago I compiled some alpha PrusaSlicer software in it's own sandbox, and tonight cmake went into the sandbox!

[chennes]

Yeah, cMake remembers things it probably shouldn't.

Try searching your system for OpenCASCADEConfig.cmake -- if you have it (for the version you actually want to use), you should be able to:

Code: Select all

cmake ../FreeCAD-src -DOpenCASCADE_DIR=/path/to/that/cmake/file/

If you don't have it, then you will (probably) need to manually set the OCC paths:

Code: Select all

cmake ../FreeCAD-src -DOCC_INCLUDE_DIR=/usr/include/opencascade -DOCC_LIBRARY=/path/to/libTKernel.so

[BDL42]

The only OpenCASCADEConfig.cmake in my system is the one in the alpha PrusaSlicer. So I need to use the second option.

For pointing to libTKernel.so, do I simply use -DOCC_LIBRARY=/path/to/libTKernel.so which is the base library, rather than
-DOCC_LIBRARY=/path/to/libTKernel.so.7.5.1? The actual path is /usr/lib/x86_64-linux-gnu

Thank you for being so helpful. As you can tell, I'm not a wizard at this...

[BDL42]

This is what I executed at the command line:

Code: Select all

$ cmake ../freecad-source -DOCC_INCLUDE_DIR=/usr/include/opencascade -DOCC_LIBRARY=/usr/lib/x86_64-linux-gnu/libTKernel.so

It seems that the "sandboxed alpha code" wasn't sandboxed, since I am still picking up the following:

Code: Select all

-- OCC:                         .. [/home/xxx/Apps/PrusaSlicer/deps/build/dep_OCCT-prefix/src/lib] [/home/xxx/Apps/PrusaSlicer/deps/build/dep_OCCT-prefix/src/include/opencascade]
-- OCC_Libs:                    [TKFillet;TKMesh;TKernel;TKG2d;TKG3d;TKMath;TKIGES;TKSTL;TKShHealing;TKXSBase;TKBool;TKBO;TKBRep;TKTopAlgo;TKGeomAlgo;TKGeomBase;TKOffset;TKPrim;TKSTEPBase;TKSTEPAttr;TKSTEP209;TKSTEP;TKHLR;TKFeat]

Seems my system is messed up, darn.

[chennes]

You can try deleting your CMakeCache.txt file and running the command again, to see if your local cache is messing things up. You can also try (again deleting your cache first) setting CMAKE_IGNORE_PATH, e.g.

Code: Select all

cmake ../freecad-source -DCMAKE_IGNORE_PATH=/home/xxx/Apps/PrusaSlicer/

[adrianinsaval]

what OS are you running? is there a package something like occt-dev available in your package manager that would provide the cmake config file?
