Thread: c function - undefined symbols
Sorry in case of double posting, wasn't registered when I tried it the first time! Hi! I am currently trying my first steps in writing my own functions in C. I read through the documentation and tried the most simple examples as shown in <http://www.postgresql.org/docs/8.3/static/xfunc-c.html>. Sadly this was already the point where I stumbled. I luckily compiled and tested the add_one integer variant. But as soon as I added the add_one_float8 I couldn't link no more. My linker dies with. Undefined symbols: "_Float8GetDatum", referenced from: _add_one_float8 in foo.o ld: symbol(s) not found collect2: ld returned 1 exit status Following the documentation I only added "/Library/PostgreSQL/8.3/include/**" to my header search path. What else do I need to configure? Thanks for your help! steffn Environment used: OS X 10.5.5 XCode 3.1 Postgres 8.3.4
