[tlcoons@localhost ~]$ cd $WM_PROJECT_DIR
[tlcoons@localhost OpenFOAM-2.4.0]$ ./Allwmake > make2.log 2>&1
[tlcoons@localhost OpenFOAM-2.4.0]$ icofoam --help
bash: icofoam: command not found...
[tlcoons@localhost OpenFOAM-2.4.0]$

I attached the make2.log compressed as make2.log.gz
I'm not sure what to look for concerning icofoam command?
Thanks for your help.

I started getting errors when autoRefineMesh was being compiled.

Quick answer: Sorry, I didn't know that Fedora 23 had upgraded their Flex version. I've updated the instructions here: https://openfoamwiki.net/index.php/I...dora#Fedora_23

To fix the problem you're having, please run the following commands:

#Go into OpenFOAM's main source folder
cd $WM_PROJECT_DIR
 
#Change how the flex version is checked
find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='

And then you can try building again, by running:

#Go into OpenFOAM's main source folder
cd $WM_PROJECT_DIR
 
# This next command will take a while... somewhere between 30 minutes to 3-6 hours.
./Allwmake > log.make 2>&1
 
#Run it a second time for getting a summary of the installation
./Allwmake > log.make 2>&1

Thank you Bruno! Seems a recent update to my F22 system installed to offending flex version. This post got me going again.

Hello

I have tried the same with OpenFOAM 2.3.X in Fedora 26 and it works
