Tutorilals fail to compile

[Anon.]

Hi,

I'm completely new to Irrlicht but I'm starting a project using it. I'm just trying to work through the tutorials before doing my own thing, but I can't compile them on my home machine. Its running Debian 3.0r1 with a vanilla 2.4.22 kernel. I've seen it compile on Redhat 7.2 machines (which I don't own so didn't setup) and a linux server (disto unknown). The errors I get are:

% make

I've got the latest download from irrlicht.sourceforge.net. Do I need to upgrade something within my setup or something?

Hi,

A quick update on my thought on this problem. I've tried compiling on my redhat 7.3 server, and it gets through to the linking stage.. hence I've deduced that g++ 2.95.4 doesn't like the syntax of the union{ struct{ ... }; bool[]; } } for field declaration, while 2.96 can handle it. I'm not sure about this linking problem.. I'll take a look.. probably after an upgrade of gcc... if I can stomach that!

Just in case you're wonderring about the linking issue:

/tmp/cc7ano1f.o: In function `main':
/tmp/cc7ano1f.o(.text+0x3a): undefined reference to `irr::createDevice(irr::video::EDriverType, irr::core::dimension2d<int> const &, unsigned int, bool, bool, irr::IEventReceiver *)'

This is on a redhat 7.3 server (again 2.4.22) tho I'm not too concerned until I get back to working on my main machine...

Cheers,

M

It sounds to me like it might be fixed by upgrading gcc

[niko]

Yes, it should work with g++3.2.. I should really write this down somewhere in the next version.

[mark]

Ouch... all the way up to gcc3.2. That's a big jump to put a linux box through (especially a debian box that shipped with a 2.2.20 kernel). Does it completely fail on all gcc2.9x's, or is it still possible to compile with gcc-2.96 or something?

I could switch to Gentoo linux to get a gcc3.2 system (and then finding a way to downgrade Gnome 2 to Gnome 1.4!) - but I can't do that the the other machine I need to run it on... I've got stacks of redhat 7.2 machines I could really do with working on (gcc2.96 I beleive).

Cheers for your help so far...

Well actually that wasn't as horrific as I imagined it would be.

Thanx for you help... Time for a little GUI tweaking (me and my crazy idea for circular windows... )

hello all,

it would really be good if there would be a note about the gcc version required in the readme - and even better if it could compile with gcc-2.95 as i.e. debian woody (the latest stable release) uses this version and other older linux installations.

i ended by installing gcc-3.3.2 in parallel of gcc-2.95.4 (write if you want me to post how i did...)
i can successfully compile all examples (except Techdemo which has no makefile :-(

but i tried to compile some other application and get
$ /opt/gcc-3.3.2/bin/g++-3.3.2 Camera.o Main.o -o test -L"/usr/X11R6/lib" -L"../../irrlicht-0.4/lib/Linux" -lIrrlicht -lGL -lXxf86vm -lXext -lX11 -lz -ljpeg

Main.o(.text+0xdd): undefined reference to `irr::createDevice(irr::video::EDriverType, irr::core::dimension2d<int> const&, unsigned, bool, bool, irr::IEventReceiver*, wchar_t const*)'

mark, what did you do to resolve your linking problem?
i know that the irrlicht library is found, because gcc complains when it does not find it.

Hi to all of you!

I've got the same problems like dbu. I'm using Suse9.0. The gcc version is 3.2 or something like that. To compile i use the command:

g++ -I"...path to my irrlicht includes..." -L"... Path to the irrlicht libs..." main.cpp

Hope that's quite all right. When compiling one of the tutorials
there's a similar text:
undefined reference to `irr::createDevice(irr::video::EDriverType, irr::core::dimension2d<int> const&, unsigned, bool, bool, irr::IEventReceiver*)'

Thanks for helping!!!!!

Well, my linking problems just went away :-)
If you just installed gcc , you maybe have to call ldconfig - and you have to make shure the right versions of the standard libraries are used.
