Installation experiences

[svenskmand]

I have pkg-config installed. It is when I want to build the binary and source packages inside of pbuilder (it is kind of a virtual Ubuntu install to determine dependencies) that I get the error, and it is shurely because I have done something wrong or am missing to do something, but I do not know what :S

So in other words it is not a compilation bug resulting from a normal compilation of the game on my system, but from me trying to package the game :S

[oln]

Adding pkg-config (and a bunch of other stuff) to build-dependencies worked, but we hit other problems after that.

Oh yeah, forgot to say that. Thanks oln

When building current from sources git clone git://opendungeons.git.sourceforge.net/ ... endungeons, I get :

LDFLAGS='-lpthread' make -j5

I thoguht its something with the pthread lib , but a few tricks I know failed. Please help me

[oln]

I think you are right about the adding "-lpthread", though I think LDFLAGS gets overridden by cmake. I would guess there has been some change to glibc/gcc or something that requires explicit linking to pthreads.

I pushed a commit adding the commands for linking to pthreads in the cmake script, so try updating from git and see if that helps. (Make sure you are on the development branch.)

[paul424]

After upgrading from the devel branch, I got similar errors :

Linking CXX executable OpenDungeons.bin

[oln]

Strange. It should link against pthread now.

[paul424]

Can you show which line is responsible for linkage of pthreads under linux , here's the current CMakeLists.txt : http://dpaste.com/hold/695600/ . I see only explicit lines for Win32 system.

[oln]

Line 375 here, seems you haven't got the latest version from the repository.

[paul424]

Ok Finally build the current branch.
Well there is one another problem , namely :
============================================
./OpenDungeon.bin

svn co https://opendungeons.svn.sourceforge.ne ... eons/media OpenDungeons


Here are the SVN logs :

thats all what goes into gui directory.

SO what I do wrong ?
regards

[oln]

Hm, that file isn't used on my system, so I assume it depends on what XML parser CEGUI is compiled with. It is present in the CEGUI source package; http://sourceforge.net/projects/crayzed ... z/download. (In datafiles/XML_Schemas) So you could try to drop that in the gui folder and see if that works. (If it does I will add it to the svn repo.)

[paul424]

I had to copy paste the foloowing files :

Imageset.xsd
Font.xsd
Falagard.xsd
GUIScheme.xsd

BUt after all the Xerces parser crashes :

Thing is I use CEGUI in version CEGUI-0.7.5 - the one avaliable from the openSuse repos. SO what do we do now ?

[oln]

The problem is that we've used CEGUI with a different XML parser (TinyXML) in the past which doesn't validate the xml files. This has resulted in some bugs in the XML files which the Xerces parser which is more strict is picking up. The problem here seems to be a misspelling, it should read layoutOnWrite. I haven't been able to work much on the project lately due to arm/shoulder problems, so I haven't had the chance to go through and fix these issues. (So if you can get it to run that would be really nice, then we could commit the changes to the repository.)

[oln]

I fixed the XML errors and commited to svn and git. The game runs with the xerces parser on my machine now.
I got a std::bad_alloc exception after running the game for a short while, but I assume that's unrelated.

[svenskmand]

Nice work

[paul424]

After disc crash and rebuilding whole thingie again from git branch development and svn I get those after compile and run :
*** Initializing OIS ***
*** FrameListener initialized ***
*** Initiliasing Console ***
*** Initialising script engine AngelScript ***

And its not a April Fool's joke, sadly .

[StefanP.MUC]

Hmm, I have no idea what's the reason for that. For me everything works fine with the latest git, also when I do a total rebuild.

Did you do anything else than checking out and compiling?

No idea what to post else .... the only modfication is SFMT library from unstable repo ( SUSE FACTORY ) + edit in plugin.cfg

PluginFolder=/usr/lib64/OGRE-1.7.4

[StefanP.MUC]

Strange... It seems that the AS compiler is not able to compile the sripts for some reason (that's the error message suggesting). I have no idea why, however. AngelScript is in our repo and the scripts, too. So we should use the same versions of both, for me it's working fine. Really no idea where to look for the error...

Maybe someone else with Linux can check if that happens for him, too?

[oln]

Doesn't happen for me (ubuntu 11.10).

Have you tried simply recompiling?

[oln]

I am getting the crash now as well, I didn't get it before because I hadn't put the scripts in the build folder so they never got compiled.

[oln]

Fixed the issue in the latest git.

[StefanP.MUC]

Nice. But I wonder why I never got this crash... I always run the game with the script files.

[oln]

Could be compiler differences or optimisations, looking at what I had to change (found an old post with a similar problem with a const function with a const reference, but it's not needed here anyway.):

{l Code}: {l Select All Code}

-        inline const unsigned int& getMaxAIThreads() const {return maxAIThreads;}
-        inline void setMaxAIThreads(const unsigned int& maxThreads) {maxAIThreads = maxThreads;}
+        inline const unsigned int getMaxAIThreads() const {return maxAIThreads;}
+        inline void setMaxAIThreads(const unsigned int maxThreads) {maxAIThreads = maxThreads;}


[StefanP.MUC]

Ah, yes, I remember. There are some left of this (const reference on primitive types) at a few places, I had this on my personal TODO list, but always forgot about it...
