Sorry, I didn't look into the package details. salome-smesh is the same of the source package, the binary packages are actually libsalome-smesh and libsalome-smesh-dev. Is the dev package necessary? I guess so.
sudo apt install libsalome-smesh-dev

will automatically install both packages.
Ah, thanks this works.
Any idea? That file is on my system, in /usr/include/smesh/SMESH_Gen.hxx
I have this variable in the conda-recipe:

-D SMESH_INCLUDE_DIR

I also tried to build with flatmesh and netgen and failed, and after a search found that both require pybind11 2.2, while Ubuntu 18.04 provides 2.0. Goody, I didn't remember that.

I'm not sure, I recall running into problems using this package back when I packaged it but nobody else was using it so I didn't continue troubleshooting. Glad to see it's getting some attention now.
Like my FreeCAD work? I'd appreciate any level of support via Patreon, Liberapay, or PayPal! Read more about what I do at my blog.

Looking in the cmake-output it seems find_package(SMESH CONFIG) was not successful:
-- Could NOT find SMESH (missing: SMESH_DIR)
ERROR================
SMESH not found.
================
So I guess either the cmake-configuration file is not found (maybe placed in a wrong dir) or the configuration file doesn't work for ubuntu without patching. This is the file:

That one was not listed in cmake-gui... Is it possible to create it manually?

BTW I think you need to add this as well:

There is only one single variable in CMake for smesh, SMESH_DIR and I set it to /usr/lib/cmake/salome-smesh.
I use cmake-gui, but based on what you wrote, you need to add this:

Code: Select all

      -D SMESH_DIR=/usr/lib/cmake/salome-smesh

Should be a "+ Add Entry" button upper right.

Thanks, it's pretty visible too. :oops: In my defence, I asked that on my phone this morning.

Okay, I added it, no change, the build fails with the same error.

regarding external smesh:

The problem is that the libsalome-smesh stores the SMESHConfig.cmake in /usr/lib/cmake/salome-smesh/ . But in the FindPackage(smesh CONFIG) looks for a directory smesh/*Config.cmake (At least I guess this is how things work). So we need to rename /usr/lib/cmake/salome-smesh/ to
/usr/lib/cmake/smesh/

Doing this worked for me (at least the cmake-detection of external smesh)

Code: Select all

sudo cp -r /usr/lib/cmake/salome-smesh /usr/lib/cmake/smesh
and then using this variables for cmake:

Code: Select all

cmake -D BUILD_QT5=ON \
      -D PYTHON_EXECUTABLE=/usr/bin/python3.6 \
      -D FREECAD_USE_PYBIND11:BOOL=ON \
      -D USE_BOOST_PYTHON:BOOL=OFF \
      -D BUILD_ENABLE_CXX11:BOOL=ON \
      -D BUILD_PLOT:BOOL=OFF \
      -D BUILD_SHIP:BOOL=OFF \
      -D FREECAD_USE_OCC_VARIANT="Official Version" \
      -D BUILD_FLAT_MESH:BOOL=ON \
      -D BUILD_FEM_NETGEN:BOOL=ON \
      -D ENABLE_MED:BOOL=OFF \
      -D FREECAD_USE_EXTERNAL_SMESH=ON \
      ..

In the long run it would be nice to rename the smesh-cmake-directory directly in the package. Or are there any conventions about the naming for this which prevent us from this?

edit.: we also have to patch the SMESHConfig.cmake:

replace line 9 and 10:

Code: Select all

set(SMESH_INCLUDE_PATH "${SELF_DIR}/../include/smesh")
set(SMESH_LIB_PATH "${SELF_DIR}/../lib")
to

Code: Select all

set(SMESH_INCLUDE_PATH "/usr/include/smesh")
set(SMESH_LIB_PATH "/usr/lib/x86_64-linux-gnu/")
