Issue with gsl #6

rx_dmfit_makefile.txt Hi,

I am very interested in using your software, but am having compilation issues.

I am using DarkSusy 6.3.1 and followed https://github.com/alex-mcdaniel/RX-DMFIT/issues/1 to deal with the issue of this version being newer than whay RX-DMFIT was initially designed for. I had to change -lisospin to -lsuperiso since that github issue concernes the older DarkSusy 6.2.0.

My makefile is attached. The issue I have is with rather with the gsl package. Doing

make example1

creates the executable example1. But then running %./example1 in the terminal gives

./example1: error while loading shared libraries: libgsl.so.27: cannot open shared object file: No such file or directory I installed with a prefix from https://www.gnu.org/software/gsl/. After unzippping, I followed the install instructions in gsl-2.7.1/INSTALL. I did:

./configure --prefix=path_to_gsl_2.7.1_install
make
make install

where path_to_gsl_2.7.1_install is an absolute path. and 'make check' shows that all checks pass, so I believe I installed the gsl package correctly. I do have a line in the RX-DMFIT makefile

prefix_gsl = path_to_gsl_2.7.1_install Following the suggestions about shared libraries in https://www.gnu.org/software/gsl/doc/html/usage.html#shared-libraries, I tried in the linux terminal:

LD_LIBRARY_PATH=path_to_gsl_2.7.1_install/lib
export LD_LIBRARY_PATH
./example1

which then gives 

creating Target...
