I'm currently trying to install some software (NUFEB) onto my home PC which is running Ubuntu version 19.10. This requires my computer to have the GNU C and C++ compilers gcc-5 and g++-5. I do not have these on this PC; I have gcc-9 and g++-9.

Does anyone know how I might be able to install g++-5 and gcc-5 on Ubuntu 19.10?

Please note that neither

sudo apt install g++-5

or

sudo apt-get install build-essentials

work!

  • Have you attempted building it with g++-9? – vidarlo Apr 02 '20 at 17:27
  • @vidarlo Yes I have. The issue occurs when I run ./install-sedifoam.sh, errors are thrown if I don't have g++-5 specifically installed. – Jack Dawson Apr 02 '20 at 17:32

    What error do you get on the g++-5 install? The install will not change the default g++ link, which will still point to g++-9. – ubfan1 Apr 02 '20 at 18:39
  • What errors do you get when you run ./install-sedifoam.sh? I don't have 19.10, but I just tried it on 18.04 with OMPI_CXX=/usr/bin/g++-9 and it didn't seem to complain (at least, not until after the link phase, when it complains about wmake and $WM_OPTIONS) – steeldriver Apr 02 '20 at 19:24
  • Jack Dawson : May be you got an old version of NUFEB ? Latest is https://github.com/nufeb/NUFEB → → $ git clone https://github.com/nufeb/NUFEB --recursive ... No issues, gcc -9.3.0 / mpixx -9.3.0 : $ ./install.sh – Knud Larsen Apr 02 '20 at 19:42
  • @ubfan1 I get the error when installing sedifoam - it gives me the error: make: *** [softParticleCloud.dep:4: Make/linux64GccDPOpt/softParticleCloud.o] Error 127 /bin/sh: 1: g++-5: not found – Jack Dawson Apr 03 '20 at 10:47
  • @steeldriver I think I needed to install OpenFOAM for make to work - you need to use 'of240' in terminal before you run other commands. I'll try changing OMPI_CXX though and see if that works - thanks for the suggestion. – Jack Dawson Apr 03 '20 at 10:50
  • @KnudLarsen I didn't have any issues with the early steps of installation, it was just when it came to using ./install-sedifoam.sh - I think this might be due to the version of OpenFOAM that is uses. I'll try recloning it though and see if it works. - Thanks – Jack Dawson Apr 03 '20 at 10:53
