Hello All!

I have a strange problem - I was trying to introduce new pyrolysis model but could not compile the program. I wrote the code basing on a existing model but could not execute "wmake" command.
Afterwards I delete everything and wanted just to compile the models which is originally supplied with OF but the command "/opt/openfoam211/src/regionModels/pyrolysisModels/wmake" returns:

"......
noPyrolysis.C.text+0x4ed): undefined reference to `Foam::solidChemistryModel::New(Foam::fvMesh const&)'
Make/linux64GccDPOpt/noPyrolysis.o.data.rel.ro._ZTVN4Foam12regionMode ls15pyrolysisModels11noPyrolysisE[_ZTVN4Foam12regionModels15pyrolysisModels11noPyrol ysisE]+0x80): undefined reference to `Foam::regionModels::regionModel::evolve()'

collect2: error: ld returned 1 exit status
make: *** [OpenFOAM.out] Error 1
"
Any idea what can be reason of this? I run "wmake" command as a root.

You may have accidentally deleted the original implementation files.

Undefined reference to `Foam::solidChemistryModel::New(Foam::fvMesh const&)` means that the compiler is unable to find the implemenation of the New selector.

Try this:

git checkout /opt/openfoam211/src/regionModels/pyrolysisModels
wclean  /opt/openfoam211/src/regionModels/pyrolysisModels
wmake libso /opt/openfoam211/src/regionModels/pyrolysisModels

What happened?

Hello Tomislav,

Thank you for your answer. By "I deleted everything" I meant "I restored everything to and come back to the original settings, I did not remove or modify any files that were initially installed with OF. That is why I am so confused.

1. /opt/openfoam211/src/regionModels/pyrolysisModels# git checkout
fatal: You are on a branch yet to be born
2./opt/openfoam211/src/regionModels/pyrolysisModels# wclean
3."wmake libso" seems to do its job, It does not give any errors,
ending with "'/opt/openfoam211/platforms/linux64GccDPOpt/lib/libpyrolysisModels.so' is up to date."

However command wmake still return the error.

Very confusing...

`wmake` is used in the older versions to compile applications and `wmake libso` to compile libraries.

Since the version '2.2.1', the build system has been modified so that you can compile libraries using `wmake` without the `libso` option. You can find it in the release notes for the 2.2.1 version under Compilation. You are using the 2.1.1 version, so you must compile your libs with 'wmake libso'.

Thank you Tomislav, you are right - now I can compile everything.
