Title: (Solved... kinda) Undefined reference to '_imp_{manythings}' (Code::Blocks)
Post by: HollaFoil on February 28, 2019, 05:42:12 pm

Even though it's my third time linking SFML, I just keep on getting new linker errors. I downloaded the source code, compiled it (static) for both release and debug. I don't think I forgot any linker/compiler paths, dependencies or flags, or whatever else there is to remember. Though, obviously I screwed up somewhere and I have no clue where..

Can you show your new command line and compiler log please?

Okay, honestly, I have no idea what is happening. It works... but...

After restarting C::B I found the release target build working. Did some work there. Closed C::B, came back after an hour, now it didn't work, but the debug one did. Literally made 0 changes appart from switching build targets. Hey, it works, I'll leave it.

Btw, -DSFML_STATIC always updated back to SFML_STATIC. -D simply did nothing.

-D is the command line flag. But if you add the symbol from the Code::Blocks GUI then you don't need it; I guess if you put it anyway then it's smart enough to ignore it.
