Hi,
I am using ert code generation and would like to add a custom library for linking during building.
But i can only add options. Adding libraries is not possible. It will always be added before the -o files. Actually I want to add the pthread library for linux project
but I am getting an undefined reference:
Version:1.0 StartHTML:0000000100 EndHTML:0000004363 StartFragment:0000000100 EndFragment:0000004363

As I understood a Makefile is generatd which only gives the -lm as a library linking option. Which makefile I have to change?
