C Library project structure


Recommended Posts

I cannot find much help on how the C Libraries are implemented. I am now trying to structure a large project. The IDE manual says the libraries are for Background C Programs, there was a time they couldn't be used in CPLCs but I see they are linked to these now so I assume is fixed.


Before I go too far:


1) I am struggling to get one library to reference another:


I have a "network.c" library setting up sockets and containing standard read/write calls.

I have a "network_utils.c" library which contains some logging utils and other small methods.


I have a few Background Programs which call methods from both. This is fine.


Now my "network.c" library needs to call methods in "network_utils.c". I have #included the header but the build gives errors like "Error : undefined reference to `LogS'"



2) Do they work in rticplc or usrcode yet?
