[Ubuntu Daily PPA] Transitioning to OCCT7, VTK7...

[triplus]

Didn't test it yet but just wanted to say thanks.

In the lines of the established culture of crediting in FreeCAD community thanks especially to you @gdo35. As without your help it wouldn't have happened.

Interestingly, I found on the Debian git repository for the netgen package a debian/5.1.dfsg tag for building a netgen 5.1 package. It dates back 3 years ago. Why the heck haven't they completed the work?

I'll try to see if it can be of use with 5.3.1.

https://anonscm.debian.org/cgit/debian- ... n/5.1.dfsg

Link isn't working tonight. Their whole Git system appears to be down.

EDIT: ok they're back. Now too late to do anything...

[NormandC]

@ blacey I'm in need of help on netgen again

EDIT: see my reply below, it seems to require patching, I'll try that tomorrow...

For those not on Gitter, you can apply netgen nglib patch set for OCCT 7.x as follows:

Code: Select all

tar xvzf netgen-5.3.1.tar.gz
cd netgen-5.3.1
curl -L https://github.com/FreeCAD/homebrew-freecad/releases/download/0/nglib-occt7.patch | patch -p1

Done, now I try to compile it against my libopencascade debian packages. The development files are in /usr/include/opencascade/, while the libs (*.so*) are in /usr/lib/x86_64-linux-gnu/.

In his compilation script, bernd does this:

Code: Select all

./configure --prefix=/opt/local/FreeCAD-0.17 --with-tcl=/usr/lib/tcl8.5 --with-tk=/usr/lib/tk8.5 --enable-occ --with-occ=/opt/local/FreeCAD-0.17 --enable-shared --enable-nglib CXXFLAGS="-DNGLIB_EXPORTS -std=gnu++11"

Here's one of the things I tried:

Code: Select all

./configure --with-tcl=/usr/lib/tcl8.5 --with-tk=/usr/lib/tk8.5 --enable-occ --with-occ=/usr/lib/x86_64-linux-gnu --enable-shared --enable-nglib CXXFLAGS="-DNGLIB_EXPORTS -std=gnu++11"

But the occ path doesn't look right.

Maybe this is the problem?

Any pointers would be appreciated.

Just had a look at the debian packaging of netgen-4.9.13, it requires a patch to solve the occ-dir issue. Seems like this is still the case with 5.3.1.

configure-occ.patch

Code: Select all

Change OCC include directory and the Togl lib name to Debian's.

I'm in need of help on netgen again

EDIT: see my reply below, it seems to require patching, I'll try that tomorrow...

Any pointers would be appreciated.

Thanks!

Happy to give it a go...

1) First, make is failing to find the OpenCascade include file BRepAlgo_AsDes.hxx. The author hardwired the include paths in the configure.ac/configure script so the nglib formula on macOS mutates the configure script because the include files are not installed into one of the author's hardwire paths. It seems you need to do the same on Linux. Perform a find to locate the header file to determine the proper include prefix.

Code: Select all

find /usr -name BRepAlgo_AsDes.hxx

It should find the include file somewhere under /usr. If find is unable to locate BRepAlgo_AsDes.hxx then you will need to double-check that the opencascade package installs all the header files. Record the full prefix for the include file BRepAlgo_AsDes.hxx...

2) Below is the section of the netgen configure script that you will want to examine and possibly change:

Code: Select all

if test a$occon = atrue ; then

        OCCFLAGS="-DOCCGEOMETRY -I$occdir/inc -I/usr/include/opencascade"

        OCCLIBS="-L$occdir/lib -lTKernel -lTKGeomBase -lTKMath -lTKG2d -lTKG3d -lTKXSBase -lTKOffset -lTKFillet -lTKShHealing -lTKMesh -lTKMeshVS -lTKTopAlgo -lTKGeomAlgo -lTKBool -lTKPrim -lTKBO -lTKIGES -lTKBRep -lTKSTEPBase -lTKSTEP -lTKSTL -lTKSTEPAttr -lTKSTEP209 -lTKXDESTEP -lTKXDEIGES -lTKXCAF -lTKLCAF -lFWOSPlugin"

If step 1 reveals /usr/include/opencascade is the full prefix for BRepAlgo_AsDes.hxx, then you should be able to build netgen using --with-occ=/usr/lib/x86_64-linux-gnu because the author hardwired /usr/include/opencascade as one of the include paths and it will set occ-dir to /usr/lib/x86_64/lib. I doubt that is the case though because it failed to find BRepAlgo_AsDes.hxx. So just add "-I/usr/<full_include_prefix_from_step_1>" to the OCCFLAGS line in configure and run configure again.

3) Once you have a working configure script, you can use something like sed to edit the configure script before running configure or create a patch file for the configure and apply it before running configure.

[NormandC]

Thanks Bruce.

Code: Select all

find /usr -name BRepAlgo_AsDes.hxx
/usr/include/opencascade/BRepAlgo_AsDes.hxx

Below is the section of the netgen configure script that you will want to examine and possibly change:

But it's not the same content after applying your patch, re:

For those not on Gitter, you can apply netgen nglib patch set for OCCT 7.x as follows:

Which I applied:

Code: Select all

if test a$occon = atrue ; then
 
-	OCCFLAGS="-DOCCGEOMETRY -I$occdir/inc -I/usr/include/opencascade"
+	OCCFLAGS="-DOCCGEOMETRY -I$occdir/inc -I$occdir/include"
 
-	OCCLIBS="-L$occdir/lib -lTKernel -lTKGeomBase -lTKMath -lTKG2d -lTKG3d -lTKXSBase -lTKOffset -lTKFillet -lTKShHealing -lTKMesh -lTKMeshVS -lTKTopAlgo -lTKGeomAlgo -lTKBool -lTKPrim -lTKBO -lTKIGES -lTKBRep -lTKSTEPBase -lTKSTEP -lTKSTL -lTKSTEPAttr -lTKSTEP209 -lTKXDESTEP -lTKXDEIGES -lTKXCAF -lTKLCAF -lFWOSPlugin"
+	OCCLIBS="-L$occdir/lib"

So I need to go back to the original unpatched configure file at least for that section because it's an undesirable change on Ubuntu.

Thanks.

Ah, sorry about that. I have regenerated and re-uploaded the patch set for you but this time without patching configure. Give it a shot and let me know how it goes.

[NormandC]

No problem, thanks for updating the patch, I'll try it over the weekend.

@ HoWil and bejant
Glad you find it useful, I'm happy that the PPA is now on par with OS X and Win regarding OCC, now I hope we can update netgen and vtk.

Compiling netgen is proving a pain...

I had to make a change in the configure file:

Code: Select all

if test a$occon = atrue ; then

        OCCFLAGS="-DOCCGEOMETRY -I$occdir/inc -I/usr/include/opencascade"

        OCCLIBS="-L$occdir/lib -lTKernel -lTKGeomBase -lTKMath -lTKG2d -lTKG3d -lTKXSBase -lTKOffset -lTKFillet -lTKShHealing -lTKMesh -lTKMeshVS -lTKTopAlgo -lTKGeomAlgo -lTKBool -lTKPrim -lTKBO -lTKIGES -lTKBRep -lTKSTEPBase -lTKSTEP -lTKSTL -lTKSTEPAttr -lTKSTEP209 -lTKXDESTEP -lTKXDEIGES -lTKXCAF -lTKLCAF -lFWOSPlugin"

The last library referenced, "FWOSPlugin", was removed from Open CASCADE 7.0.0. bernd hasn't removed it from his patched netgen repo, I'm surprised it manages to compile!

So after this slight change it seems to build fine with make, but afterwards the make install step is where I trip. Actually I don't want to do make install because I have no idea if I'll be able to remove it afterwards. So I used checkinstall instead, because it creates a basic .deb package I can easily uninstall.

But no matter what I do, it does not install all the required files. When I try to configure FreeCAD with BUILD_FEM_NETGEN enabled, I get bunches of errors about missing files. I also have to manually set a lot of paths for netgen which is pain, because I'm not even sure these paths are correct.
