SDL and MSEgui.

[fredvs]

Hello.

https://en.wikipedia.org/wiki/Simple_DirectMedia_Layer

There is a gem in MSEuniverse:
https://github.com/mse-org/mseuniverse/tree/main/sdl4msegui

The readme.txt:

---

Main concept of porting MSEgui to Windows, Linux, Mac OS, Android and iOS :

• Use SDL 2 for windowing, input event, thread management, networking, audio, and I/O management for all OS
• Use OpenGL context only for drawing from SDL2.0 (http://wiki.libsdl.org/moin.cgi/CategoryVideo)
• 2 options for 2D drawing engine, use cairo or mseopenglgdi.pas
• Use cairo for drawing engine, put pixels from cairo surface to opengl texture.

---

The project dates from 2012 and was not yet tested for Linux.

Here is the updated sdl4msegui testsdl for Linux:
[EDIT] Updated demo with image:
testsdl.zip

In Project_Options, Make tab, adapt the directories to target the patched source of mseide-msegui/lib

Here the patched version of mseide-msegui/lib for Linux:
[EDIT] Updated some SDL methods missing and fixed crash when closing the app.
lib_sdl_180524_2.zip

Note that this is absolutely not yet finished, but yes, some things are working yet.

Have lot of fun!

Hi Fred,
Can you tell which dependencies bring moving to SDL? So far strong point for fpGUI / MSEGUI was little footprint, basically only X-11. IIRC cairo is part of GTK no? Hmm, or not, maybe GTK is based on Cairo, yes that is I think

[fredvs]

Hello Dibo.
I am explorer in the SDL world but it seems to me that for SDL only one or two lib are needed (have to check).
Imho cairo is totally independent and can be used by many os.
Roland Chastain knows cairo and has done some demos using MSEgui.

Nice that you appear now, I just have finished the implementation of ICY tag from web-radio streams (like name of current song, picture, and other infos).
It was a old wish that finally is done.
I will commit it to uos very soon.

Here used by SWP:

[fredvs]

I used this:

sudo apt-get install libsdl2-2.0-0

[dibok]

On linux you can call command ldd <your app> on your SDL demo to see what are real dependencies

[fredvs]

I am not with my work-dev-laptop, this we I may have it and compile a MSE-SDL app to see what it needs.

[fredvs]

OK. (but SDL2 needs lot of dependencies...)

Nice that you appear now, I just have finished the implementation of ICY tag from web-radio streams (like name of current song, picture, and other infos).
It was a old wish that finally is done.
I will commit it to uos very soon.

I think it could be my wish some times ago, I'm glad that you implemented it

[fredvs]

The commit was done yesterday.
Added demo consolewebstream_icytag and updated demo simplewebplayer with ICY tag.
