Linking shared objects such as openblas

[wdeshazer]

I am working on a project and need to use openblas. Documentation for the server that I am working on suggests using:

-L$(BLAS_DIR)/lib -lopenblas

Where BLAS_DIR is an environment variable

BLAS_DIR=/fusion/usc/c8/opt/env/gcc-8.3.1

I have tried many approaches but my most recent and best attempt was the following:

$(BUILDDIR)/gtnpydep: gtn/main.F gtn/calctransm.F gtn/gtn.v
	$(FORTHON) -a $(INSTALLARGS) -a $(FCOMP) $(DEBUG) --fargs  "-LUMFPACK2 -lumfpack -L$(BLAS_DIR)/lib -lopenblas" --interfacefile gtn/gtn.v -f gtn/main.F gtn $(GTN_SRC) 
	touch $@

What is the correct syntax for incorporating a library?

The error that I am encountering is that python can't find the symbol dgesv_, which I have confirmed is in libopenblas.so

(gtneut_env) [deshazere@omega-a pygtneut_develop]$ python gtneut_run.py
