Known Build Issues
Intel MPI (Gcc/Clang)
Either I_MPI_ROOT or MPI_ROOT can be used to specify the Intel-MPI
installation directory path.
The ThirdParty build of ptscotch uses `mpiicc` for Intel-MPI
instead of the usual `mpicc`.
When gcc or clang are used, it is highly likely that the
I_MPI_CC environment variable also needs to be set accordingly.
See `mpiicc -help` for more information about environment variables.
Intel Compiler
Since OpenFOAM uses C++11, a fairly recent version is required.
The Intel compiler - icc (ICC) 17.0.1 20161005 is ok, but the
initial release - icc (ICC) 17.0.0 20160721 - has a bug that
will result in these types of error messages.
MatrixSpaceI.H(492): error: no instance of overloaded function
"Foam::MatrixSpace<Form, Cmpt, Mrows, Ncols>::Block<SubTensor,
BRowStart, BColStart>::operator=" matches the specified type
If using the runTimePostProcessing to create on-the-fly images, you
can simply just compile ParaView and these libraries will be used.
If you elect to use a separate VTK compilation (for example for
off-screen rendering), it is advisable to reuse the VTK libraries that
are provided with ParaView by making an appropriate symlink
prior to using makeVTK. This doesn't just reduce disk-space, but works
much better than using the VTK tar file.
Using runTimePostProcessing with the 'plain' VTK libraries does
generally work, but does not exit cleanly:
symbol lookup error: .../linux64Gcc/VTK-7.1.0/lib/
undefined symbol: _ZN33vtkFilteringInformationKeyManager13ClassFinalizeEv
symbol lookup error: .../linux64Gcc/VTK-7.1.0/lib/
undefined symbol: _ZN49vtkInformationQuadratureSchemeDefinitionVectorKeyD1Ev
This error appears to be suppressed if VTK is compiled with a Debug build-type.
Building on older systems
If the system gcc is too old for building OpenFOAM, a third-party gcc or
clang/llvm installation can be used. If building clang/llvm, note that
there are also minimum gcc/g++ requirements there:
Min gcc/g++
=========== ==========
4.4 llvm-3.4.2
4.7 llvm-3.5.2 - llvm-3.7.0
If your system compiler is too old to build the minimum required gcc or
clang/llvm, it is just simply too old.
ThirdParty clang without gmp/mpfr
If using ThirdParty clang without gmp/mpfr, the ThirdParty makeCGAL
script will need to be run manually and specify that there is no
gmp/mpfr. Eg,
./makeCGAL gmp-none mpfr-none
Subequent compilation with Allwmake will now run largely without any
problems, except that the components linking against CGAL
(foamyMesh and surfaceBooleanFeatures) will also try to link against
a nonexistent mpfr library. As a workaround, the link-dependency can
be removed in wmake/rules/General/CGAL :
