Hi
On Centos-7 with GCC-4.8.5 and OpenFoam-7, I get this error for missing UPstream.H file while everything look normal and I have sourced etc/bashrc file.

and

[marzieh@hpc OpenFOAM-7]$ find . -name UPstream.H

Any idea to fix that?

Hey,
have you ever managed to remedy this issue ?
I´m facing it now as well ...

Since OpenFOAM compromises many source files in many different directories and subdirectories, it would be tedious and error-prone to have all of them listed as include directories. To get around this, when any OpenFOAM library is compiled, the first step is to create an "lnInclude" directory with soft-links to all of the headers. If these are missing, or have incorrect links, you will get the type of error that you are seeing.
I am not sure where you got your package (built it yourself, downloaded somewhere,..) but you will need to recreate these directories.
Try something like this :

cd src/
wmakeLnIncludeAll -update

BTW if you are using CentOS, you could also give the precompiled packages a try.
https://develop.openfoam.com/Develop...ompiled/redhat

In this case the '-devel' subpackage would contain the sources and the corresponding lnInclude directories

It works well!!! The code "wmakeLnIncludeAll -update" solves the problem about "Upstream.h not found"
