You might try to install libesd0-dev

Sudo apt-get install libesd0-dev

[Sledgenet]

Aha, so it is libesd0-dev that I need -- thanks! Looks it is deprecated, updated installation instructions can be found here: https://askubuntu.com/a/1082739

However... that merely punts the problem a little further down the field:

In file included from /home/[ME]/Downloads/BlitzMax/mod/sdl.mod/sdl.mod/SDL/src/audio/nas/SDL_nasaudio.c:34:0:
/home/[ME]/Downloads/BlitzMax/mod/sdl.mod/sdl.mod/SDL/src/audio/nas/SDL_nasaudio.h:29:10: fatal error: audio/audiolib.h: No such file or directory

Likely this is just a chain-reaction of broken-ness so don't sweat it. I check NG probably once or twice a year to see if it is "just works" territory yet so I got my answer 😃

I am not on 18.xx yet...and for me it runs without further issues. Think Brucey needs to check it out in a 18.xx VM. Maybe SDL has some more instructions for the requirements with these audio backends.

[GWRon]

If you did not update the modules yet...maybe update brl.mod pub.mod sdl.mod ... from their repos. So an updated SDL mod might already solve your issue

[Sledgenet]

Appreciate the suggestion -- getting the same issue with the latest versions of those mods pulled unfortunately. Ubuntu Software Update ran an upgrade literally a couple of days ago so I think I've just picked the worst time possible to give this a go.

[GWRon]

Tried to replicate it:

• downloaded release
• error during extraction of the download (a file within sdl.mod was not found), manually unpacked everything else (drag n drop out of the archive manager), downloaded sdl.mod and placed it into the mod dir
• had to install "libwebkitgtk-3.0.0" too to get MaxIDE running
• error in sdl.mod/sdl.mod/SDL/src/audio/esd/SDL_esdaudio.c - "esd.h" not found.

So seem that audio backend needs to get disabled ?!

[GWRon]

For now you might continue your blitzmax-exploration by opening up "sdl.mod/sdl.mod/linux_source.bmx", scroll some lines down, and comment out the line importing the esd file:

replace:

?linux And Not raspberrypi
Import "SDL/src/audio/esd/SDL_esdaudio.c"
Import "SDL/src/audio/pulseaudio/SDL_pulseaudio.c"

with

?linux And Not raspberrypi
'Import "SDL/src/audio/esd/SDL_esdaudio.c"
Import "SDL/src/audio/pulseaudio/SDL_pulseaudio.c"

also replace two lines in each sdl.mod/sdl.mod/include/linuxx64/SDL_config.h and ../linuxx86/SDL_config.h:

#define SDL_AUDIO_DRIVER_ESD 1
#define SDL_AUDIO_DRIVER_ESD_DYNAMIC "libesd.so.0"

with:

#define SDL_AUDIO_DRIVER_ESD 0
#define SDL_AUDIO_DRIVER_ESD_DYNAMIC

(without this replacement you end up with some undefined references to "ESD_BOOTSTRAP")

The SDL dynamically links to backends, so if it (ESD, PulseAudio, ...) was not available, it uses another one. Means it should run without ESD too (on a client's computer).

Make sure to completely recompile the SDL.mod modules (not "quick") as you else end up with undefined references (it mixes cached precompilates with the new, esd-free, ones).

[GWRon]

@woollybah
SDL should be "reconfigured" to not use ESD for Ubuntu 18.04+ - it also seems that it is kind of deprecated (PulseAudio 2.0 drops support for ESounD, development of the lib seems ...dead). So it might not be a missed backend by the default BlitzMax-target-audience.

[GWRon]

Brucey updated sdl.mod ...please give it a try and close the issue if the commit solves your problem.

[Sledgenet]

Thought I'd swing by for another crack at it. Latest NG repo with latest pub.mod, brl.mod and sdl.mod:

In file included from .../BlitzMaxNG/mod/sdl.mod/sdl.mod/SDL/src/audio/nas/SDL_nasaudio.c:34:0:
.../BlitzMaxNG/mod/sdl.mod/sdl.mod/SDL/src/audio/nas/SDL_nasaudio.h:29:10: fatal error: audio/audiolib.h: No such file or directory

It is different at least :D

[GWRon]

Did you install the modules listed in the bmx-ng/sdl.mod readme.md file/project start page:

libasound2-dev libpulse-dev libaudio-dev libx11-dev libxext-dev libxrandr-dev libxcursor-dev libxi-dev libxinerama-dev libxxf86vm-dev libxss-dev libgl1-mesa-dev libesd0-dev libdbus-1-dev libudev-dev

? (was not able to check it on my own, not on 18.x yet and on my old Mint rig it compiles)

[Sledgenet]

I was missing libaudio-dev from that list -- everything building now. Thanks GWRon, much appreciated.
