hello,
new in OpenFOAM i have installed OF in W10 following the guide from József Nagy (guide).
i was trying to use a parametric blockMesh, (I am copying the code at the end of the post) where I use #calc in it and I gives me error when using it:

I am completly new to linux and from the error, if i understand correctly i have no writes or i have missing files... and dont know how to solve it.
if anyone could help i would appreciate it
Code:

well with some help, i found the solution! i leave the post for anyone else that has this issue:
I installed some things for ubuntu and solved everything:
sudo apt-get update -y

sudo apt-get install -y make

sudo apt-get install build-essential

I've met the same problem today, and the re-installation of make didn't help.

I solved this issue by using ' #eval{ }; ' expression replacing all the ' #calc " "; ' expressions in blockMeshDict.

uff.... quiet old thread... forgot to post the solution, yes i did the same. nevertheless, it is important to notice that #eval is only for the .com version
