[FLASH-USERS] FLASH 4.8 not compiling - LAPACK library error

[Hansen, Eddie]

Hi Gabriel,

On some machines, this will work:
LIB_LAPACK = -llapack

You can also explicitly set the lapack path in your Makefile.h just like the HYPRE and HDF5 library paths. In other words, something like this:
LAPACK_PATH = /path_to_lapack
LIB_LAPACK = -L${LAPACK_PATH}/lib -llapack

Subject: [FLASH-USERS] FLASH 4.8 not compiling - LAPACK library error
Dear all,

I finally got FLASH 4.6.2 to run on my OpenSuse 15.6 machine. It is currently working in parallel and has shown no issues so far. However, when I try to run FLASH 4.8, using the exact same libraries and the same launching script, I run into a new error.

"ERROR: A Config in your simulation requires the lapack library”

Now, my machine has the lapack libraries installed, but I am unsure if for FLASH4.8 one needs to add the path to the LD_LIBRARY_PATH variable or similar. If I follow the compiler’s advice and add an empty LIB_LAPACK variable to my Makefile.h, then the code does not work either, and runs into a FatalError during make.

Any clues on how to fix that?

Best,
