It seems as if the GameServer.cpp needs Debug.h which needs <execinfo.h>  
Unfortunatly it is not working to simply delete that line. 

the complete build.log is attached.

[Comment 2 Felix Janda 2015-09-17 22:17:16 UTC]

musl does not have the backtrace functionality from <execinfo.h>. So we
will need to stub out that functionality to make it compile.

After removing the include, is it enough to replace
"backtrace(stacktrace, maxTrace)" by "0" in order to make it compile (or
at least to get to a different compile failure)?

patch to make it compile

Thank you for the information. I found the odd part in Debug.h, changed it as suggested, and it compiles fine. 

The only problem now is the localisation, which is falling back to english for no obvious reason. I guess I should ask upstream for help in this case?

[Comment 4 Felix Janda 2015-09-20 05:22:29 UTC]

I have some suspicion about what the problem might be. rttr uses its
own gettext library[1], whose implementation for some strange reason
tries by default to convert all strings to ISO-8859-1 using iconv().
This does not work with musl because musl's iconv() can only convert
to UTF-8.

[Comment 5 tt_1 2015-09-20 06:27:21 UTC]

there seems to be a references to ISO-8859-1 in mygettext/src/gettext.cpp 

so, what can be done to fix this? obviously the solution must be a bit more complicated than simply to edit these few lines?
