This breaks the ABI, so you have to do it also for the debugging build. You cannot use the TLS headers with a non-TLS libpari. However, I would advise to install the debugging build somewhere and using the headers and the library from the debugging build. This would avoid this kind of issues entirely. Of course , you can use gp2c-dbg to compile your module. Cheers, Bill.
