Hello to all,

I would like to install OpenFOAM v2112 in debug mode in Ubuntu 22.04. The compiler used in Ubuntu 20.04 is GCC 9.4. In Ubuntu 22.04 the default is GCC 11.2.0.

This is giving me problems with the installation. I have installed GCC9 with:

sudo apt install gcc-9 g++-9

How can I specify the the GCC version I would like OF to be compiled with?


The error I am getting is:

primitives/functions/Math/erfInv.C: In function ‘Foam::scalar Foam::Math::erfInv(Foam::scalar)’:
primitives/functions/Math/erfInv.C:45:21: error: ‘numeric_limits’ is not a member of ‘std’
   45 |         return std::numeric_limits<scalar>::infinity();

Well,

I added to src/OpenFOAM/primitives/functions/Math/MathFunctions.H

#include <limits>

and it has been compiling.


Edit:
After compilation when running the pitzDaily tutorial with simpleFoam, I get the error:

--> FOAM FATAL IO ERROR: (openfoam-2112)
error in IOstream "sha1" for operation Foam::Ostream& Foam::operator<<(Foam::Ostream&, int32_t)

[tRock]

Any idea, on how to solve this?

I also tried compiling with g++-9 and gcc-9

sudo apt install build-essential sudo apt-get install gcc-9 g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 9 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-9 9
sudo update-alternatives --config gcc # To select gcc version [9.4.0]
sudo update-alternatives --config g++ # To select g++ version[9.4.0]

After compilation, I still get:

--> FOAM FATAL IO ERROR: (openfoam-2112) error in IOstream "sha1" for operation Foam::Ostream& Foam::operator<<(Foam::Ostream&, int32_t)

When running the pitzDaily tutorial.

How can I solve this?

I'm struggling gcc version, too.

today, I tried to compile openfoam for Ubuntu 20.04, and somehow, I would like to install 9.3.0 instead of 9.4.0, but I found it's so hard to change. I tried multiple ways, all failed.

Have you ever compile openfoam in ubuntu 20.04? I got error ".../OSspecific/POSIX/POSIX.o] Error 1.

Hi,
On Ubuntu 20.04 I never experienced any installation issues.

[tRock]

has anyone been able to install OF through the source in Ubuntu 22.04?


What procedure did you use to make it work?


Best regards

For me it worked out to complile with gcc-10. To do this you first have to install it by:

sudo apt install gcc-10 g++-10

After this you can add the following line to /etc/bashrc:

export WM_COMPILE_CONTROL="version=10"

With these changes it should compile without any errors.
