Hello,

After building this, i can't execute xenia :

Can you help me please ?

Thank you for your work, it looks promising !

[mrcmunir]

Use gdb ./xenia

And put bt for more info depurate why crash it.

[Wirexuser01]

Thanks for your answer.

Here the result :

Reading symbols from ./xenia...(no debugging symbols found)...done

I built xenia without "travis-retry", is it serious?

[mrcmunir]

@Chrissis You missing run and not put bt command.

1. gdb ./xenia
   Reading done.
   After that
2. run
   When crash
3. bt command for backtrace .

Oh sorry, I never used the debug tool ^^

I have the same problem after updating xenia, except that the error seems a little different this time :

Linux is a WIP, and isn't functioning yet.
