Hello, I'm unable to compile DSDA-Doom on Ubuntu Linux, this is the error log:

I've tried 0.27.5, 0.28.3 and master branches. Always I got the same error. GCC/G++ 10.3.

Well, we do CI on Ubuntu. So, which version of Ubuntu is this and which version of the fluidsynth library?

[wlcif]

Ubuntu 18.04 i686, FluidSynth 1.1.9.

Looking at FluidSynth's repo, it seems to me that new_fluid_defsfloader() is only available since version 2.0.0: FluidSynth/fluidsynth@f55e90a

[ceski-1]

Loading a soundfont from memory (for SNDFONT support) requires at least FluidSynth 2.0.0. If this source port continues to support FluidSynth 1.x.x, I think that requires an #if FLUIDSYNTH_VERSION_MAJOR == 1 block that writes the SNDFONT lump to a temporary file and then loads it.
