Hey all,

Just downloaded the Horde3D lib and noticed it was windows only

. So I created a simple Makefile to compile it. Here are the results:

Code:

[kcbanner@infiltrator Source]$ make

As you can see windows is quite lazy with its newlines at the end of files (it doesn't comply to POSIX

).

Anyway I can see there were quite a few headers not found. I assume these are windows only headers?

Anyway thats my results.

Oops! I didn't realize I needed to include the Shared folder for .h files.

Here is the results:

Hello,

Marc Schuba, a student researcher from the University of Bielefeld, has recently successfully ported Horde3D to Linux. Luckily only a few changes were necessary. We are currently integrating these to the Horde main branch, so the next version should be much easier to compile under Linux and other platforms.

Hi.

Good to hear of the port for Linux. I have been trying to port it myself, but now I guess I'll drop it and wait for the next release. :wink:

If you need any help integrating code and/or seting up a build for Linux, I would be happy to try and help.

By the way, is there a IRC/other channel set up for Horde3D?

Thanks for offering your help! I myself have only little experience with Linux programming, but at the moment everything looks quite good. If there are still problems I will come back to your offer.

Currently there is no chat system set up for Horde. With the community still being quite small at the moment, I think the forums should be enough.

BTW, I am abroad for five days now and so I probably won't be able to post here...

Hey marciano.

Just thought I'd ask, what build system are you thinking of using for Linux? I reakon it would be good to use something relitvely simple and compact to match the engine.

Maybe just simple Makefiles? I reakon it would be pretty simple/compact, at least for a start. But then it might get overly complex to maintain (and large) in the future?

Automake? It might be the most complex/bloated. It's a pretty good build system in general I reakon, just maybe not suited to Horde3D?

Or maybe another one like Jam, Cmake, or Scons? With somewhat limited experience with Jam, so far, it seems pretty good to me (more simple, less files) compared to Automake. I haven't really got into the other two (or any thing else).

Just wondering out of interest.

Also, what build system(s) for Linux does everyone else think would be a good match for the engine?

Hi.

As a windows and Visual Studio user I don't have any experience with build systems so I can't say much about that. I hope someone else will take care of that, my goal now is to make the code completely platform independent. But as you already said it should be something that fits the project, thus lightweight and easy to use. Might be a simple make file would really be a good start. Horde will still grow a bit but one of the goals is that it should always remain lightweight and uncomplicated.

It would be nice to use a meta-build system like MPC.
We use MPC at my work to generate Visual Studio project/solution files, but AFAIK it can also produce makefiles for *nix and workspaces for other IDEs.

I'm glad to announce that Horde is officially cross-platform now

The new version compiles fine under Linux (at least our Ubuntu test system). We just use simple make files which were quite easy to write after reading some good tutorials...

Hi

Tried to build the 0.12 release on a 7.10 Ubuntu installation and got a lot of messages like this :

eirik@pcubuntuamd:~/Builds/Horde3D SDK [0.12.0]$ make all
#
#
#

g++ -c egRendererBase.cpp -oegRendererBase.o -I../../Dependencies/Include -I../Shared -fPIC
utOpenGL.h:153: error: ‘void (* glBlendColor)(GLclampf, GLclampf, GLclampf, GLclampf)’ redeclared as different kind of symbol
/usr/include/GL/gl.h:1662: error: previous declaration of ‘void glBlendColor(GLclampf, GLclampf, GLclampf, GLclampf)’

/usr/include/GL/gl.h:1659: error: previous declaration of ‘void glBlendEquation(GLenum)’

...

Looks like there are some functions that have been redeclared with different notation. Any idea hove to resolve this ?

Regards
Eirik

Hello, the code was working on Ubuntu 7.04; obviously there must have been some changes to the GL headers.

I have completely removed dependency from gl.h now. Luckily I had the chance to test it on Ubuntu 7.10 and it is working now. Here is the updated file:

http://www.nextgen-engine.net/tmp/utOpenGL.h

Hope that helps!
