I try to use the srf API and I have a link error. When I did :
FuncCallContext *funcctx; ... if (SRF_IS_FIRSTCALL()){ funcctx = SRF_FIRSTCALL_INIT(); // If I remove this line, no link error ... } I have this link error : "undefined reference to 'init_MultiFuncCall(FunctionCallInfoData*)'". The init_MultiFuncCal function is in the funcapi.h file, but where is the associated library ? I try all the libraries of PostreSQL, but no success .
