so then i installed libpulse-dev, which helped. but then:

Mhhhh, I believe this is as a result of our linux support for sdl2 being still a tad hacky.
We generate a bsconfig with the "correct" (hardcoded) linux linking flags here: https://github.com/bsansouci/SDL-mirror/blob/fast/postinstall.js#L135

But since on linux we run the configure script and build from scratch, these link flags might end up being wrong for some platforms (seems like yours is one of them). We need to instead pull the right static linking flags from the generated pc files (https://github.com/bsansouci/SDL-mirror/blob/SDL12/sdl.pc.in#L14)

@bsansouci

[Schmavery]

@raould can you paste the contents of node_modules/sdl2/sdl2.pc?

[mciparelli]

In my case I get a bunch of these

can not be used when making a shared object; recompile with -fPIC

Any idea how to workaround this?

[Schmavery]

@mciparelli unless sdl is mentioned explicitly in the error message, that unfortunately looks like another occurrence of bsansouci/bsb-native#35 (and likely isn't related to this issue).

[bsansouci]

@mciparelli Could you paste the contents of node_modules/sdl2/sdl2.pc so we can figure out if you have different generated linker flags on your machine?

[mciparelli]

yeah it looks like this

# sdl pkg-config source file

@raould the dependency on libpulse-dev should be removed for cases where your distro doesn't use pulseaudio.
Please reopen or otherwise let us know if you're still having issues, and if the error looks like this, please include the contents of node_modules/sdl2/sdl2.pc just so we can check what sdl2 wants us to link :)
