Dear all, I'm using OF ver
Dear all,

I'm using OF ver 1.3 and I got into a problem related to compilation of a modified source file. I've been searching for relevant threads here and I found many tips that I thought might solve my problem, but in fact I haven't got the compiling right.

Before doing more substantial change of a solver, I just simply want to see if I can compile a slightly-modified source correctly and can observe the change in FoamX. So I chose to modify icoFoam, as follows:

(1) I added Info syntax into "createFields.H":

Info<< "Testing Here !!\n" << endl;

dimensionedScalar nu

I did this in hope to see "Testing here" in the log file after executing the solver.

As far as I know from this forum, I also have to do something with "Make/files" and "Make/options" as follows:

(2) I replaced FOAM_APPBIN with FOAM_USER_APPBIN in Make/files:



(3) My Make/options is unchanged and looks like:



After compiling with wmake I got the following:

Making dependency list for source file icoFoam.C

collect2: ld returned 1 exit status
make: *** [/home/zaki/OpenFOAM/zaki-1.3/applications/bin/linuxGcc4DPOpt/icoFoam] Error 1

Judging from the above message, I think there's a problem with the writing of path in Make/options. So I checked the LIB_SRC directory:

echo $LIB_SRC

but all I got is an empty line.

And also, when I checked the following directory:

cd ~/OpenFOAM/zaki-1.3/applications/bin/linuxGcc4DPOpt/

no further directories nor files exist.

Any idea of how I should tackle this problem?

Thanks a lot,

It looks like a confusion in y
It looks like a confusion in your environment set-up: do you have WM_64 set on or off?

Currently, the compile line says you are trying to compile a 32-bit version and the path vhere libraries are sought looks 64-bit to me. You will need to sort out your environment veriables - there is nothing wrong with your code.

Thanks for your quick reply,
Thanks for your quick reply,

I checked the following file:

and I found that WM_64 is set as on.

I tried to turn it off and do . ~/.bashrc again. But after compiling, similar message occured.

Am I on the right track or not?

Thanks again,

whooops, Sorry for the last

Sorry for the last message. I got it right now. I should've set WM_64 as on. After setting it as off and re-setting it as on, and do . ~/.bashrc, I had no compiling error.

I can now view the change in FoamX.

Thanks Hrv!
