Hello all,

I have issues building foam-extend 3.2 on my Gentoo-box. I have installed several OF-versions on it without any problems.

The error occurs when buidling metis. The problem is that decompositionMethod.H is not found even though the file is present.

Thanks.

Quick answer: Without a complete output log with error listing, I'm unable to diagnose what might be the problem.

Append the following to the command you used:

> log.make 2>&1

For example:

./Allwmake > log.make 2>&1

Then please attach the compressed file, e.g. "log.make.gz":

gzip < log.make > log.make.gz

Quick answer: OK, there are few errors and hopefully the solutions are simple enough:

1. The rpm and rpmBuild applications are not installed in your system. I don't know if Gentoo provides it.
2. There are a few problems with the Flex version. The following commands should solve the problem:
   

   cd $WM_PROJECT_DIR
    
   find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='

Ok, I don't think I need rpm and rpmBuild. I have all required dependencies on my System and OpenFOAM3 is able to use them without any problems. The same is true for the installed flex.
I will try to fix the flex problems as described. What is the correct way to tell foam-extend to use the system packages? Thanks.

Quick answer: Run:

foam
cp etc/prefs.sh-EXAMPLE etc/prefs.sh

Then:

1. Manually edit the file "etc/prefs.sh";
2. uncomment the lines respective to the packages you have in your system and don't forget to update the paths to said packages/libraries.
