[SDL] configure doesn't find libpulse-simple

[Spencer Parkin]

Hi.

It's midnight and I'm ready to give up (and I'm going to be so groggy at
church tomorrow), but before I do, I'm going to try the mailing list...

On Unbuntu, using "sudo apt install libsdl-2.2.0-0" appears to install
something, but I have no idea what. No headers or library files for SDL
can be found after running this command, so I resorted to trying to compile
SDL myself. This appeared to work, but my application could never open an
audio device. After doing some research, I believe the problem is that
there are no useful audio-backends compiled into SDL. To confirm this, I
compiled one of the test programs that enumerated the backends (drivers)
and sure enough, "pulse", "ogg", "alsa", etc., are all missing from the
list. So I re-ran the configure script and checked the output and found
that it couldn't detect the libraries for these lower-level audio drivers.
Taking "libpulse-simple" as an example, I found this in my
"/usr/lib/x86_64-linux-gnu/" directory, but it's still not detected.
Oddly, I can't confirm the installation with "pkg-config --listall | grep
pulse". Running "autoreconf", whatever that does, doesn't help either.

I'm at a loss. I wouldn't bother with compiling SDL if I could just
install it. Is SDL a dead project? Does the SDL development team support
Ubuntu?

Thanks,

If using package management, you probably need to install the -dev
versions of SDL also. The one you installed only installs the dynamic
library. The dev package also installs the headers. This is not SDL
specific, but a general convention of how package management works on
Linux.

If you are building from source, you need to make sure you installed
all the -dev packages for all the libraries SDL wants, otherwise the
configure system will not find anything and not build those
components.

In the SDL source, read the docs/README-linux.md. It has explicit
instructions about which packages you should install for Ubuntu.

Thanks, Eric. Installing libsdl2-dev set everything straight. My
application is up and running and making sound effects through my
speakers..hurrah!

I do my main development in windows, because I just haven't found an IDE in
linux that I like. Developer studio has its problems, but it's still way
better than anything I've tried in linux. So when I want my stuff to run
in linux, I have to always port it over. Using cross-platform libraries
helps, of course, but there are always snags.
