General / Re: Ye olde "undefined reference" errors.

« on: September 08, 2015, 01:50:34 am »

Windows 8.1, 64 bit. I was working off that tutorial, yes. The .txt file was not included in my distribution, which, looking at it now, was the wrong distribution. So that probably explains that.

In fact, that allowed it to build.

I'm still getting a startup error when I run the project, but I haven't learned how to debug yet, so I'll try my hand at that before asking around.

Thanks for the assistance, gentlemen.

General / Ye olde "undefined reference" errors.

« on: September 07, 2015, 02:19:15 am »

Trying to get 2.3.1 to work with CodeBlocks 13.12.

Just running through the tutorial here , as well as a few , unable to get the test program from the tutorial to build.

One point in the tutorial confused me, it differentiated between DW2 and SJLJ installations of GCC, but it doesn't seem to specify which is needed. Should I build my own SFML? I have libgcc_s_dw2-1

I'm using dynamic linking, as I read that's preferable so you can freely change the libraries without needing to screw with the executable. I do have include in the compiler tab, lib in the linker tab. Since I'm not using static linking or debug versions, my link libraries look like "sfml-graphics" and such. I believe have heeded the link order - graphics, window, system, audio, main network.

Apologies if I've left any crucial information out, the sooner I can get past this unpleasant know-nothing phase, the better. Thanks in advance.

Edit: it appears I have done all that careful tinkering in the debug rather than the release tab. Currently finagling, wish me luck.

Now we're looking at:

I have ensured that my build and build options are configured to release - no mixing and matching as far as I can tell. Tried putting SFML_DYNAMIC in #defines, but it didn't appear to have an effect.

Current course of action is install the latest version of MinGW and rebuild sfml for it. Should be fun!

Edit 2: I had the compiler selected which comes with Code Blocks rather than the one I installed. After selecting the proper one, I'm down to two errors:

Still trying to work out CMake. Grabbed a copy of CMakeLists.txt, put it in the SFML directory, and tried CMake again. It started to work, but is currently complaining "install FILES given no DESTINATION!"

Here's the log it left behind. Currently stumped.
