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

[赵旭]

Hi Gabriel,

Have you tried to comment the following line in Makefile.h ?

#----------------------------------------------------------------------------
# Fake existence of iso_c_bindings module to prevent unnecessary recompilations.
#----------------------------------------------------------------------------
#ifeq ($(FLASHBINARY),true)
#iso_c_binding.mod :
#       touch $@
#endif

This is works for me in FLASH 4.8

Hope this help,
Xu

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?
