CEGUI (Crazy Eddie's GUI) Forums

Hello,

Meanwhile I'm frustrated. Since three days I try to setup anything for the CEGUI & OGRE Tutorial, but fail with CEGUI on Windows in the MinGW environment. So far, I installed MinGW & OGRE (c:/mingw & c:/ogresdk), and both work nicely. Then the trouble began ...

As CEGUI-SDK for MinGW does not contain the CEGUIOgreRenderer.dll I came to the conclusion to build CEGUI myself. The given Building CEGUI Tutorial seem useless, as those steps are for VC. I modified the project/premake/config.lua anyway:

Appears like I have to install MSYS (MSYS, msysDTK) to c:/msys/1.0 (what I never have done before). Next, I downloaded the CEGUI sources, and installed them into the home folder.

1. Bootstrapping

The bootstrap script did not work properly, so I updated autoconf, automake, libtool, m4. After running again, I was recommended to add AC_CONFIG_MACRO_DIR([m4]) to configure.ac & ACLOCAL_AMFLAGS=-I m4 to Makefile.am, what I have done.

Unfortunately I don't get further, and get following output (note, though you can just run bootstrap, for clarity I break it's commands down here):
I ommit the other commands (autoheader, automake, autoconf), as bootstrap doesn't display their error messages I have.

2. Configure

Somewhere I read to directly start with configure is okay, so I skipped bootstrapping after I didn't come any further with the above errors. Indeed, after installing pkg-config, glib, freetype-dev, and pcre-bin configure works so far, but ...
... as you see the Ogre Renderer is NOT enabled, but that's what I need.

I'm not sure if Lua is needed (because of config.lua), but I downloaded, build, tested, and installed it anyway:

Still no luck. Lua is installed to local by the way .

3. Make

Though I am not satisfied with the above cofiguration I gave it a try, and started to make it (requires pcre-lib). Successfully, but as anticipated without the Ogre Renderer.

I stuck here, and appreciate any help - getting this done or binaries - to continue with the CEGUI+OGRE tutorial.

Thanks

Hi, Laz. It seems pkgconfig isn't finding the metadata for OGRE. Try adding the path to the OGRE's *.pc files to PKG_CONFIG_PATH variable before you run configure.

Edit: I forgot, in order to use the ogre renderer in the samples you need OIS:


This is in acinclude.m4 in case you are wondering.

The fact the SDK is missing the CEGUIOgreRenderer DLLs is a mistake, so I apologise for that. I'll try and make sure that 0.7.3 includes all the files!

Unfortunately I don't have any experience with MinGW + MSYS, so can't advise much on that specifically, unless we just treat it the same as linux.

I can confirm that unless you do certain things, there is no need to run bootstrap on the source release packages, and should just run the provided configure script.

Lua is not needed unless you want to use the Lua script module. Those lua files in projects/premake are unrelated to that, and are not used anyway for configure / make command line builds.

With the above clarifications and IE3uL's advice, hopefully you can move forwards

Thank you very mucho! That helped me a lot.

1. pkg-config

As I couldn't find any OGRE*.pc & OIS.pc files, I copied them from Linux into the lib/pkgconfig directory of MSYS, and adjusted them a little to my installation. I know it's ugly, but I had to change the Cflags as below (instead of Cflags: -I${includedir} -I${includedir}/OGRE -pthread) to successfully configure with Ogre Renderer enabled.



2. Make

The compilation needs Boost, which can be found in the OgreSDK, and just copied it to MinGW (boost to include/boost, lib to lib).

Also pthreads is required, and I renamed it to libptread.dll.a in MinGW's lib folder.

Now, make and drink a beer

3. CEGUI & OGRE Tutorial

With the new files I am able to build the tutorial, pass the 'OGRE Engine Rendering Setup', and then it fails.

Here are the error messages of Ogre.log:

CEGUI.log has no error messages, but on the command line:

Argh ... so close - but I am tired and sloppy now.

I think you did not properly initialize CEGUI. Have a look at http://www.cegui.org.uk/docs/current/rendering_tutorial.html

OGRE doesn't generate the pkg-config files on msys (I've attempted a couple of times to fix this but never got it working 100%). I usually send up telling CEGUI about ogre using Ogre_CFLAGS, etc.

I wasn't aware of that, i made the assumption they were available, he found a workaround tho =D

Indeed, had to add CEGUI::System::create(*mRenderer); after bootstrapSystem.

Still not through (CEGUI.log):

This confuses me again. Ogre did create the resource groups (Fonts, Imagesets, Layouts, LookNFeel, Schemes) and adds their location. The pathes in resource.cfg should be correct (tested absolute & relative).

When I hardcode the path in my source code TaharezLook.scheme is found, but have to edit pathes inside there. Of course this isn't desired by me.

Anyway, it's late enough here. Have a nice weekend.

You don't have to call System::create() yourself, the bootstrap function do it for you. I don't know how OgreResourceProvider works, my only advice is to check the spelling (i had issues a lot of times before with this) of the paths and resource groups names. Also, idk if is necessary with OgreResourceProvider, but with the Default RP you have to set the default resource groups



Take a look at http://www.cegui.org.uk/docs/current/resprov_tutorial.html for more details. Also, i recommend you closely read (more than once if it's needed) all the beginners tutorials at http://www.cegui.org.uk/docs/current/index.html

If you can't find the way, post the initialization code and i will take a look.

Have a nice weekend too =D

So, one bad and one good news. The bad one first: the CEGUI-OGRE tutorial still doesn't work here. The good one: CEGUIs demos do (don't know why I haven't tested them earlier).

Just want let you know that it's no CEGUI-OGRE issue. IMO the thread is solved.

Yeah, I knew that. My excuse is that those two keys are right next to each other
