Hi FOAMers,

I was trying to compile OpenFOAM7 on CentOS7 without root permission, by following https://openfoam.org/download/7-source/. However, I got error when
Code:
./Allwmake
The log file is shown below.

why do you think that the problem is related to the root permission? It seems to me that this is not the case since you were able to execute `./Allmake`.

Thanks for your reply!
I'm not sure whether they are related, lack of root permission is just the reason why I have to compile from source code...
I thought it might because that the path to flex was not in the system path, so I added $FLEX_INC to the path, however the error remained. Do you have any idea?
