Hi All,
I have developped a specific function code in my class volume defined as a "connected C Code function" in my proview release used on ARM.
I need to use this same module in my PLC so I just wanted to port a C code component from a class volume to another.
- I have redefined the class component in the class volume in term of input / output and this looks the same as the previous module.
- I have copied the C source code from my other installation to this one and compiled is successfully (corresponding .o object file is correctly generated in $pwpr_obj)
- I have added this object files in "object modules" attributes of a build option in my directory volume
- I have checked that the C code object file is correctly included in the related .opt file for my plc
Now I can build the volume without issue but the build node failed obviously due a linker error (see attchement ) but I can't find what I have missed ? Does anybody here can help me to troubleshoot my issue ?
Thanks in advance
Snarf
[EDIT] Cant succeed to add attachement so here after is the error feedback from the console:

Note:
The RegPIFo_init and exec function are defined in the RegPIFo.c file and can be successfully matched with a grep in the corresponding .o
