Does the 4.1 version have some problem compiling on line 186. Linux

I have the same problem with two server.

Sure does but this isn;t something thats compiled

Between Apache and the Xojo app there is a CGI file written in Perl
And thats whats having issues

Did you upload everything ? (libs, resources dirs etc etc etc)
As binary ?
Correct permissions ?
Often its one of those things thats the problem on the server

None of which has anything to do with compiling the app

This typically means that the compiled app is crashing before it gets a chance to respond to the cgi script. I suggest going to that location and try manually launching the app from the command line. That usually reveals the problem. In this case, the binary named “titre”.
