Hello,
I compiled the game yesterday and this is what appears in my terminal when I try to launch it :

Code: Select all

wesnoth: symbol lookup error: wesnoth: undefined symbol: Mix_FadeInChannel

And an extract of the log (I have removed the download, extract and install log) : https://c.gmx.fr/@1091385412309489919/K ... CUdiaKX41g

What version of SDL_mixer (sometimes called SDL2_mixer) do you have installed on your system? Do you perhaps have two different versions installed (maybe one compiled, one from an operating system package)? It looks like Wesnoth was compiled with version 2.6.2 but it might be using an older version (probably 2.0.4?) at runtime.

[alberic89]

Yes, I use the libsd2-mixer 2.0.4+dfsg1-3 on my main OS.
The game work on my compilation OS.
I have update to sid my compilation OS, it is for this?

The documentation for the function Mix_FadeInChannel says:

Code: Select all

 * Note that before SDL_mixer 2.6.0, this function was a macro that called
 * Mix_FadeInChannelTimed() with a fourth parameter ("ticks") of -1. This
 * function still does the same thing, but promotes it to a proper API
 * function. Older binaries linked against a newer SDL_mixer will still call
 * Mix_FadeInChannelTimed directly, as they are using the macro, which was
 * available since the dawn of time.

So in version 2.0.4 the function Mix_FadeInChannel does not actually exist because it was a macro and not a function. If you compile with version 2.6.x it's going to try to use the function version, but then if you run it with a version 2.0.4 shared library the function will not be there.

Thanks you, I will try to recompile with 2.0.4 libsdl2.

[alberic89]

It's work now.
