I was working nicely with OpenFOAM v1706 but I tried to move to v1806 and I have some errors. When I write source ~/OpenFOAM/OpenFOAM-v1806/etc/bashrc I obtain the following error:

No completion added for /home/jorge/OpenFOAM/OpenFOAM-v1806/platforms/linux64GccDPInt32Opt/bin
... incorrect platform, or not yet compiled?

Although the error, I made the installation by adding to the bashrc the line source ~/OpenFOAM/OpenFOAM-v1806/etc/bashrc and I obtained a critical error:

Software Version Location
flex 2.6.0 /usr/bin/flex
gcc 5.4.0 /usr/bin/gcc
g++ 5.4.0 /usr/bin/g++
gzip 1.6 /bin/gzip
tar 1.28 /bin/tar
icoFoam *** not installed ***


Base configuration ok.
The foam installation contains 1 critical error(s).

Review the output for warning messages and consult
the installation guide for troubleshooting.


Finally, if I try to run any case such as Pitzdaily, OpenFOAM does not recognize any of the orders such as blockMesh, setFields....
Could anyone help me?

Thanks in advance

Greetings jormollo,

Requests so that anyone can try and help you with this:
  1. Please specify which installation instructions you are following.
  2. Please indicate which Linux Distribution you are using or which other Operating System you are using.
  3. Please indicate any steps that you did differently from the instructions you've followed, if you did anything different.
Most people are only to help when they pass by the forum on their free time, so if you don't first describe how you got to this point, it's not possible for people to be able help you as fast as possible... for example, I look into the forum around once each weekend, so only next weekend I might be able to look into your next post

For future questions, please keep in mind the instructions given on this thread: How to give enough info to get help

Best regards,

Thanks Bruno, I will keep yout recommendations in mind. Answering to your questions:

1. I was following the instructions provided at (both for the pre-requisites and the build guide).
2. The version of Ubuntu is 16.04 in a Virtual Machine VM VirtualBox
3. I did not change any of the instructions.

I was struggling more and more and finally I succesfully installed OpenFoam 1806 in Ubuntu 18.04.
When I first tried the installation on Ubuntu 18.04 with only 1GB of RAM, I could not install OpenFOAM 1806 (I had exactly the same problem as in Ubuntu 16.04).
However, when I put 2GB of RAM, the installation was succesfully completed.
