Installation directory setting

[connorourke]

In the User guide its says, with reference to the installation folder:

A good location for rheoTool is, for example, directory $WM PROJECT USER DIR, which is defined by default when OpenFOAM⃝R or foam-extend is installed.

It isn't clear how to define the installation folder. At the moment it gets put in $FOAM_USER_APPBIN.

How do I tell Allwmake where to put rheoTool?

Thanks

One thing is the directory to where you clone/download the repo, which will contain the code source, user-guide and tutorials and from which you run the installer. Your transcription of the user-guide refers to that. Another thing is the directory to which the binaries (apps and libs) are written, which are $FOAM_USER_APPBIN and $FOAM_USER_LIBBIN. This is a logic choice, since they both are sourced by default by openfoam. Can you change them? Yes, in all Make/files included in the repo, but you will then have to tell the compiler and loader where to find them, unless they are already included by default.

Thanks for the answer - so to be clear: to define the installation directory all I need to do is to export the required directories to $FOAM_USER_APPBIN and $FOAM_USER_LIBBIN before compiling, and then make sure they are included in the $PATH and $LD_LIBRARY_PATH?

Yes, it is more or less like that. More info here: https://cfd.direct/openfoam/user-guide/v6-compiling-applications/.

Note: you just need to proceed as with any other c++ program, but instead of defining things in a makefile or in the terminal, you define them in Make/options and Make/files of each lib/app. Thus, you just need to understand how things are defined there.

Great - thanks.
