Can libraries be opened?

McCarra · November 16, 2010, 14:38

Hello

I tried to open a library file and my computer returned an error: not able to detect character encoding. Does it mean that libraries can't be opened? I wanted to read one while trying to understand the whole code of a tutorial.

All the best

Hi,

can you tell me the path of the library: Do you try to open a file with some *.so ending?
If you tell me which library you are interested, maybe I can tell you how to find it.

I'm looking for "libfvmotionsolver.so" which is in /opt/
openfoam171/lib/linux64GccDPOpt/. Perhaps it ios a binary file and that's why I couldn't see it.

Are all ".so" files binary?

Hi,

yes they are.

If you want to access the sourcecode you have to find the correspondig file in OpenFOAM-1.7.?/src

In your case you will find the corresponding source code in fvMotionSolver/fvMotionSolvers/fvMotionSolver/. There are three files which define the class.

What do you mean by the corresponding file? Is the one in src the same as the one in lib? What is the relationship between them?

Many thanks Kathrin!

The "corresponding file" is the source code from which th *.so file was build.
so is short for shared object.

You might want to check out some literature on compiling. Usually there are some chapters on it in the programming languages books.

Yes, that would be the answer. I'm trying to find an information source to better understand OpenFoam code.

Thanks for your help!

all the best
