Install OpenFOAM 2.1.x on ubuntu 22.04

Dear all,

I am trying to reactivate some self-made rather old OF solver, originally implemented with OF 2.1.x.

My rough plan is first to compile OF 2.1.x to ensure the solver is working prior to thinking of re-implementation the solver in a up-to-date OF framework.

Since my current system is Ubuntu 22.04 and since OF 2.1 is pretty old, I experience several complications. Several per-requisite packages available for Ubuntu 22.04 seem to be way too modern for OF 2.1. Since I couldn't find precompiled packages old enough for OF 2.1, I decided to locally compile the required packages. Therefore I used following list: https://github.com/OpenFOAM/ThirdParty-2.1.x

I tried to compile GCC 4.6.1 and also the latest GCC-4 version 4.9.4 and both wasn't successful.

Trying to compile GCC 4.6.1 failed on my system with following error:

Code:

In file included from /home/ilya/OpenFOAM/ThirdParty-2.1.x/gcc-4.6.1/libgcc/../gcc/unwind-dw2.c:333:0:

/home/ilya/OpenFOAM/ThirdParty-2.1.x/gcc-4.6.1/libgcc/../gcc/config/i386/linux-unwind.h: In function ‘x86_64_fallback_frame_state’:

 /home/ilya/OpenFOAM/ThirdParty-2.1.x/gcc-4.6.1/libgcc/../gcc/config/i386/linux-unwind.h:54:47: error: dereferencing pointer to incomplete type

Does anyone have an idea, how to overcome this issue?

Trying to compile GCC 4.9.4 as an alternative failed with following error:

Code:

checking for gmp.h... no

 configure: error: gmp.h header not found

I do not really understand the header error since gmp was already locally compiled at this moment, but the GCC installer seems to look for system-gmp intead of the local one (s. previous log enties):

Code:

---------------

Already built: gmp-5.0.2

---------------

Already built: mpfr-3.0.1

---------------

Already built: mpc-0.9

---------------

Starting build: gcc-4.9.4

I would appreciate any help on getting OF 2.1 run.

Good morning,

I have tried this with Ubuntu 20.4 and wasnt able to solve that. It was really time consuming and the outcome was nothing.

One thing I would give a try, is to use a virtual machine with an older ubuntu version and installing OF on that version

I used OpenFOAM 2.1.1 in Ubuntu 16.04 and it worked fine. Versions higher than 16.04 cause serious compatibility issues.*
Install compatible Ubuntu versions for OF 2.1.x in the virtual box.*

Thanks a lot überschwupper and Kummi,

Could you please also explain what are the advantages and the disadvantages of installing 16.04 in a virtual machine versus usual installation on a separate partition?

Cheers

Assuming you're running Windows or a Linux-based higher-version operating system on your computer. So, instead of installing and rebooting Ubuntu 16.04, install a software called Virtual Box. This software is a separate machine that helps you install any OS within the software without affecting your main computer. However, you need to allocate some memory space and RAM for it.

Thank you

Both options have their advantages and disadvantages, you can find them via a quick google research.

Lower ubuntu versions may be out of support and there are some security risks because of that. I would go for a VM set up, especially when you are calculating on a different device. Far more comfortable and you are able to work on your main OS with your applications

You can install openfoam and gcc with apt-get see https://openfoam.org/download/8-ubuntu/. beset
