How to adjust Make/options

Hi all,

I have re-written triSurface library (MytriSurface) and placed them in FOAM_USER_LIBDIR. How I want a application to use this library. How do I need to adjust Make/options:

Code:

-I$(LIB_SRC)/MytriSurface/lnInclude

Where is LIB_SRC set and how do I need to change it? It obviously points to FOAM_SRC_DIR but I can not find any environment variable LIB_SRC?

Thanks Bastian

I also don't see any environment variable LIB_SRC. Where is it defined?

Greetings to all!

(:eek: the initial post was a year and a half ago...)

OK, these kinds of variables that aren't in the shell environment, are usually defined somewhere in the wmake folder, also known as $WM_DIR:

Code:

echo $WM_DIR

Now, if you want to find out where it's located in one of those files, you can either use an advanced text editor (such as Kate or Eclipse IDE) or use the following commands:

Code:

cd $WM_DIR

find . | xargs grep 'LIB_SRC' -sl

The second line will use find to list all of the available files and folders; pipe "|" it to xargs for using each item on the list from find on grep. grep will then list the files that have the string we are searching for. Have doubts? Run:

Code:

man find

man xargs

man grep

For the lazy, the answer is as follows: it's defined in "$WM_DIR/Makefile".

Bruno

Thank you Bruno,

I saw, that the original post is very old, but since there was no answer and I was interested in, I thought I'll take the existing one instead of starting a new one.

Best regards,

Hi Illya,

No problem :) I was more stunned by the fact that the thread didn't receive any answers back then :(

Best regards,

Hello Bruno,

sorry for reopening again this years-old thread but I didn't find much about these matters in the forum.

Suppose I'm writing a small custom library with some solvers and a few additional features, let's say boundary conditions or function objects. Using a tree structure similar to the OpenFOAM one now I'm able to compile such features into a single library, to the $(FOAM_USER_LIBBIN) from a customPath/src/myLibrary/ source folder.
To access such functionalities and to link the library to my solvers, now the Make/options file of my solvers should look like:

Code:

EXE_INC = \

    -IcustomPath/src/myLibrary/lnInclude \

    -I$(LIB_SRC)/TurbulenceModels/turbulenceModels/lnInclude \

    -I$(LIB_SRC)/TurbulenceModels/incompressible/lnInclude \

    -I$(LIB_SRC)/transportModels \

    -I$(LIB_SRC)/transportModels/incompressible/singlePhaseTransportModel \

    -I$(LIB_SRC)/thermophysicalModels/radiation/lnInclude \

    -I$(LIB_SRC)/finiteVolume/lnInclude \

    -I$(LIB_SRC)/sampling/lnInclude \

    -I$(LIB_SRC)/meshTools/lnInclude



EXE_LIBS = \

    -L$(FOAM_USER_LIBBIN) \

    -lmyLibrary \

    -lturbulenceModels \

    -lincompressibleTurbulenceModels \

    -lincompressibleTransportModels \

    -lradiationModels \

    -lfiniteVolume \

    -lsampling \

    -lmeshTools \

    -lfvOptions

Now, the -L$(FOAM_USER_LIBBIN) line specifies to look for library .so files into the $(FOAM_USER_LIBBIN) directory, such that -lmyLibrary allows to find the compiled libmyLibrary.so file. This works just fine so far.

What if I decide to compile more custom libraries separately, and I want to define something like $(LIB_USER_SRC) to point to the customPath/src base folder automatically without having to specify the whole path for each -I line?

I understand that $(LIB_SRC) is defined when calling wmake, and that to define an analogous $(LIB_USER_SRC) I could in principle either modify the wmake folder or create a custom one in my library, but this seems quite overkill.
Another possibility is maybe to define it somehow in the customPath/Allwmake script, but this would prevent me to compile solvers separately during development and testing.

Is there some possibility to define a variable pointing to the base folder within the Make/options file, just as it can be done in the Make/files file?
I know, it's more a curiosity than a real necessity, but I was wondering about it and since you are one the OpenFOAM pros around here maybe you know the tricks!

Thank you!

You can set environment variable usign export command in linux. You can set LIB_USER_SRC to path you want.
