Hello,

ERROR:: ReadAndTrim: LUA not included, cannot continue
STOP 1

I suspect that lua is not active, how can I activate lua?

Thank you and looking forward to an answer.

John.

It is done at installation or compilation.

Hi,

But why ElmerSolver shows while running?,

"ERROR:: ReadAndTrim: LUA not included, cannot continue

STOP 1"

And it does not continue running, which means it stops the expected results of the code as the message shows, "STOP 1". ¿Is there a way to active lua within de code program? or a linux command to active lua before running de sif file?

Thanks and looking forward to an answer.

What system OS and how/when did you install Elmer?

The OS is Ubuntu 18.04.4 LTS and Elmer version is 8.4. I installed lua using the following commands,

sudo apt install lua5.3
sudo apt install build-essential libreadline-dev

curl -R -O http://www.lua.org/ftp/lua-5.4.3.tar.gz
tar zxf lua-5.4.3.tar.gz
cd lua-5.4.3
make all test

According to wikipedia, the lua stable version is 5.4.3.

Thanks and looking forward to an answer.

How and when did you install Elmer version 8.4?

Hi

Lua needs to be included at the time of compilation. So you cannot just add it to an existing installation. In the cmake files you should have something like: The lua source files are bundled so this usually goes smoothly. The various pre-compiled versions of Elmer should have this. Then you see something like:

MAIN: HYPRE library linked in.
MAIN: MUMPS library linked in.
MAIN: Lua interpreted linked in.
MAIN: Zoltan library linked in.

Version 8.4 is probably 2-3 years old. You should rather use a version that is up to date.
