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

[GABRIEL PEREZ CALLEJO]

Dear Eddie, all,

By adding the line LIB_LAPACK = -llapack, the compilation works. However, a new error appears (this error is also particular of version 4.8, as there is no issue with version 4.6.2).

When doing “make -j” inside the object directory, At some point the error: "Fatal Error: Reading module ’iso_c_binding’ at line 1 column 1: Unexpected EOF” appears. The file iso_c_binding.mod is indeed empty, but that is also the case in version 4.6.2, where the same file is also empty.

I believe this error appears when the make command starts dealing with the file “gr_GCReleaseScratch.F90”, but I am unsure. I am attaching here the STDOUT and STDERR from the process.

Apologies for the reiterated problems, your help is much appreciated.

Best,

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,
