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:

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:

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):

I would appreciate any help on getting OF 2.1 run.
