But as soon as, i try to use a c-caller block with some optimised functions this errore happens :
Error(s) encountered while building custom code simulation target for model 'PFC_cla'. Fix the errors in your custom code or disable 'Import custom code' if your custom code has incompatibilities.
c:\local_module\models\pfccont_br_adb_vienna_01\pfc_cla_\CLAmath.lib: member c:\local_module\models\pfccont_br_adb_vienna_01\pfc_cla_\CLAmath.lib(CLAsqrt.obj) in archive is not an object collect2.exe: error: ld returned 1 exit status
The problem is not the.h because i'm able to see the prototipes of the function.
The problem is that i don't have the .c files but some custom libraries so .lib.
