Unable to compile the engine with GCC 4.7
Hey,
I'm running Arch Linux. This is a rolling release distribution and so I'm running the latest GCC (v 4.7).
Unfortunately Cafu fails to compile now. The problem seems to be related to wxwidgets. If I replace wxwidgets with the latest version of it, it compiles, but afterwards Cafu fails again to build, because of compatibility issues.
I found this link and this seems to explain a solution to this problem: https://groups.google.com/forum/#!msg/w ... Fib2BZWP8J
If it would be awesome, if you could fix this asap.
Thanks alot,

PS: We created a ticket: http://trac.cafu.de/ticket/114

Ah, only now I'm seeing your post, after having replied to your ticket already.
I'll look into it later today.

Thanks for the quick fix! It has solved the described problem above.
Unfortunately another issue has occured in the MainCanvas.cpp now:
To be honest: I have no glue what this is supposed to mean... Have you any ideas, what might be causing the problem and how to fix this?
Still running Arch Linux 64bit .

Re: Unable to compile the engine with GCC 4.7
Does the solution proposed at http://trac.cafu.de/ticket/115 work for you?
And regarding the error about
(This isn't vanilla Cafu code, is it?)
And regarding the error about
close()
, can you fix this yourself?(This isn't vanilla Cafu code, is it?)

Re: Unable to compile the engine with GCC 4.7
Hi there,
I've encountered the same issue as the thread starter, and we are of the same distro, compiler and architecture (Arch Linux x86_64, GCC 4.7). The solution in http://trac.cafu.de/ticket/115 works. As with the thread starter is concerned, I've also encountered those "not declared" errors. I've managed to silence the errors by including unistd.h, though I'm not sure if that's the proper fix.
The compilation went smoothly after that. Btw, I'm compiling the vanilla source.

Re: Unable to compile the engine with GCC 4.7
Yes, the Ticket works. Thanks for that.
You are right, the error with close() is our fault, we'll look into that. The funny thing is, that Haimi is able to compile the code without facing the above error message. But I guess this might be again related to my system (GCC v4.7)...
I have installed GCC 4.4 parallelly now and I'm going to test, whether this might help.
Thanks again for your help!

Re: Unable to compile the engine with GCC 4.7
Thanks to you both. I've applied the patch in #115 and closed the ticket.
Regarding #115 / the dtor, with each new major release, GCC tends to provide more thorough warnings, which is usually a good thing.
Regarding
It's perfectly possible that including

Regarding
close()
, it may be possible that the error is a result of their cleaning up the header files as well; similar changes have happened in the past. If so, we'd need to include the proper header, but as I have no access to GCC 4.7 at this time, I really cannot tell anything specific about it.It's perfectly possible that including
unistd.h
is in fact the proper solution. If so, could you please post or submit a patch?Best regards,

Thanks, but why didn't you put the changes intotuldok89 wrote:ok then. here's my patch
Network/Network.hpp
?And why include
io.h
under Windows?Best regards,

Re: Unable to compile the engine with GCC 4.7
I should put it in the
network.hpp
then. About io.h
, it's the nearest win32 equivalent of unistd.h
(for the close()
, unlink()
, etc.). If it's uneeded for windows targets, then I should just include unistd.h
for linux systems.Who is online
