Hi there,

I'm having an issue linking the library to my executable:

This might well be an issue on my side but I have no clue. Any dependencies I'm not ware of? The library is compiled into a static library right?

Help is very much appreciated.

Kind regards,

Erwin

Erwin, I recompiled the feedstock conda-forge recipe and was successful to create the library.

git clone git@github.com:conda-forge/clapack-feedstock.git 
cd clapack-feedstock
conda build recipe -c conda-forge

Looking at your error message, it seems that you are missing F2CLIBS. This is where s_cat, s_copy, s_cmp,... are defined.

F2CLIBS comes with the clapack library. cmake and then make will compile it.

Thank you that fixed... I knew it was on my end ;)
