[FIXED] SDL not linking properly (kos-ports)

[Corbin]

Okay, made this in the other thread but it was probably not an appropriate place.

Trying to build my program, it almost goes through the process until I get an issue at the linker phase when it links against my program:

/resample.o obj_dc/timidity/tables.o obj_dc/timidity/timidity.o -lm -Wl,--warn-common -lgl -lpng -ljpeg -lz -ltremor -lSDL -lm -lstdc++ -Wl,--start-group -lkallisti -lc -lgcc -Wl,--end-group

/usr/local/dc/kos/../kos-ports/lib/libSDL.a(SDL_audio.o): In function `SDL_AudioInit':

/usr/local/dc/kos/../kos-ports/lib/libSDL.a(SDL_video.o):(.rodata.bootstrap+0x4): undefined reference to `_DUMMY_bootstrap'
collect2: error: ld returned 1 exit status

As I said in the other thread, not sure what exactly is happening here. Any suggestions?

I only found this http://comments.gmane.org/gmane.comp.lib.sdl/21736 (reinstalling cygwin fixed it)
So maybe you tried some things to get KOS working and that botched the installation? Sometimes people update either kos or kos-ports but not the other and that leads to binary incompatibility.
Are you using the current versions of both kos and kos-ports from git?

Can you try a fresh start on kos-ports so we can exclude any issues there?

Code: Select all

. /opt/toolchains/dc/kos/environ.sh
cd kos-ports
git reset HEAD --hard
sh utils/build-all.sh

I just deleted the kos-ports and downloaded the github copy again - copy/pasted, ran build-all, same issue. The command git reset HEAD --hard didn't work for some reason so I just did it through Explorer.

I did have to install an additional file to libjpeg (jerror) but that's all. I don't think I had to do anything to KOS, other than deleting the original folder when I had some issues and downloading the github copy, pasting it in the directory, and re-installing it.

So yes, both copies are from Github.

Other than that, I suppose I could try re-installing Cygwin but it installed without a hitch the first time, so I don't think it has to do with that.

any other ideas?

It's entirely possible SDL is broken, as I did update it with the new kos-ports work. I never tried using sound or anything, so it's probably something I did. I'll take a look when I get a chance to see what's wrong.

[BlueCrab]

SDL should link properly now. Or, at least it does for the new example I just added to the KOS examples tree...

Make sure to pull an updated copy of kos-ports and do a "make uninstall install clean" on SDL in the kos-ports tree to pick up the changes that I made to the SDL code.

[Corbin]

Thanks Lawrence! That worked perfectly! I just uninstalled the copy, modified the SDL_config_dreamcast header myself to match your changes, re-installed, and re-built my program - success!

Thanks so much again for being quick!

[BlueCrab]

No problem. I'm glad that it was pretty easy to fix, after all (especially since I pretty much blindly updated the SDL version quite a bit).

[Corbin]

Don't beat yourself up, I super appreciate it! Sometimes I do that on the engine I work on, and forget overlooked errors like that can happen under specific circumstances according to what the end-user is doing/wanting out of it. Usually because I get really excited and my brain kind of explodes

Much obliged again! =]
