Hello Raphael.
You are right. Folder /usr/share/sdcc/non-free does not exists. I build again
SDCC with this parameter:
non_free_lib_dir_suffix="non-free/lib".
Builds all, inclusive non-free lib and include, but 'make install' does not
copy non-free folder to /usr/share/sdcc.
Got the right path: /usr/local/share/sdcc and this folder has other three:
include, lib and non-free. I notice that libc18f is not in
/usr/local/share/sdcc/non-free/lib/pic16 but in but in
/usr/local/share/sdcc/lib/pic16 folder.
Issue remains, after changing parameters to right path.
This is what I get without making a string copy:

This is weird because libraries are there... Don't no what else I can do.
