[solved] 4.6.0 keeps using an old SDL build on my computer

'SDL_vulkan.h' file not found
I have no idea what dependency I'm missing. I'm assuming the wiki is not up to date.

You will need a newer version of SDL. And yes, the wiki is really out of date.

Downloaded, installed, attempted to run, and got:

Code: Select all

/opt/gzdoom/gzdoom: symbol lookup error: /opt/gzdoom/gzdoom: undefined symbol: SDL_GetWindowBordersSize
I'm guessing this is going to require that I update SDL one way or another?

Well - you might be able to self-compile a version without Vulkan support.

When inside your build folder try running cmake -DHAVE_VULKAN=0 and then see if you have any luck building that with your current SDL version.

If that doesn't work then unfortunately yes you may have to update your SDL version.

Thanks, I'll give it a try...

Code: Select all

make[1]: *** [CMakeFiles/Makefile2:811: src/CMakeFiles/zdoom.dir/all] Error 2

The first definitely looks Vulkan-specific so I'm not sure why it's there now? But I guess that SDL_GetWindowBordersSize is one of those things that's in the new SDL.

If only I could update just that without it getting me to completely overhaul or uninstall a huge amount of other stuff...

SDL2 in buster definitely has SDL_vulkan.h. The official deb is compiled against Ubuntu 18.04 which is using an older version of SDL2, 2.0.8 vs 2.0.9, just fine.

Then nothing is working and I have no idea why.

I've even resorted to Google to look up

Code: Select all

undefined symbol: SDL_GetWindowBordersSize
and literally the only result is this thread...


I've found /usr/include/SDL2/SDL_vulkan.h while searching my entire system on Seamonkey. No idea why it can't be found by the compiler. I'm guessing this file would contain whatever the blob is complaining about with that hapax legomenon error message, in which case no idea why it can't be found by GZDoom either.


And trying to add the full path for SDL_vulkan.h to sdlglvideo.cpp just gives me this unspeakable mess:
Spoiler:
Looking at this more closely it seems to be finding two files that do the same thing?


For what it's worth, I have not seen anything else break running anything else that looks like it involves SDL, so it's probably not a corrupt installation but something related to paths GZDoom is using to search for the SDL Vulkan header. I have no idea how to configure that stuff.

You seem to have SDL headers in both /usr/include and /usr/local/include and obviously they are from different SDL versions if one is incomplete.

Missing SDL_GetWindowBordersSize() declaration has not nothing to do with Vulkan support. It means that SDL2 version is older than 2.0.5. Please post output of the following command

Code: Select all

apt search libsdl2-dev

Apparently, another installation of SDL2 was picked by CMake somehow. Please run the following command instead of just make, and post command line that triggered compilation error.

Code: Select all

make VERBOSE=1

Turns out the one in /usr/local/include has a last modified date of 2015. :shock:

Moving it out of /usr/local/include into somewhere nonsensical (my home folder) did not fix it. wait.......

Here's the error with VERBOSE=1:

By deleting that old SDL2 folder I manage to get to 100% on the compiling but it ends like this:

Code: Select all

You obviously also have an old SDL binary lurking around.
