Hello.

OK, I will check it, thank to note it.

By the way, do you know that uoslib is the library version of uos?

May I ask you what kind of library you want to produce: native or Java?

[fredvs]

Re-hello.

Hum, where did you find simpleplayer_noflat.lpr in /uoslib/example ?
It is normal that it does not compile because to produce a library, uoslib needs uos_flat.pas unit.

Please try the demos in uoslib/examples, for example /uoslib/examples/demos/fpc/simpleplayer.lpr

If you are a Pascal developer and want to use uos in your application, you should use uos instead of uoslib.
And there there is a simpleplayer_noflat.lpr example (that should work).

[gitarent]

Thanks for responding so quickly :)
What I did was:

• git clone https://github.com/fredvs/uos.git testuos
• start lazarus
• open project testuos/examples/simpleplayer_noflat.lpr
• run|build
  repeated again with same result...

[gitarent]

May I ask you what kind of library you want to produce: native or Java?
I'm looking for basic play/record features for use on windows/mac/linux

[fredvs]

Ha ok, so you are talking about uos project (here you are in uoslib project).

And yes, I just try now the demo uos/examples/simpleplayer_noflat.lpr and indeed, there is a problem.

Thanks to note it.

Do you have problems with other examples, is uos/examples/simpleplayer.lpr working?

I will check+fix it tonight.

Fre;D

Ha, ok, then you should use uos.

uolib is more for C, Python or Java developers that want to use a native audio library.

fpc developers may use directly uos, not via libuos.so.

[fredvs]

Hello.

OK, simpleplayer_noflat.lpr fixed in last uos commit.

Many thanks to note it.

Nice, it compiles without errors now. ;)

however, ...
I get no sound (player seems to load a file, indicator runs) and then, if I try to close the window:

Project SimplePlayer raised exception class 'External: SIGSEGV'.

I get no sound (player seems to load a file, indicator runs)

What demo are you using?

if I try to close the window:
Project SimplePlayer raised exception class 'External: SIGSEGV'.

Did you use the debugger?
Because it is a known problem with gdb, it raise a exception at at closing uos application.

[fredvs]

Please could you try the consoleplay.prj example and give the result here.

Do you have pulseaudio installed?

sudo apt-get install pulseaudio

There is indeed problem with last alsa library with some last new audio cards.

Also pulseaudio has a new audio driver that works much better than the old alsa driver.

[gitarent]

pulseaudio is already the newest version (1:13.99.1-1ubuntu3.3)
