Problems with header files for KO

Peter

While trying to build KO I get this error but I have bullet-dev installed on my Xubuntu:

In file included from ../KO/src/luckey.h:76,
                 from ../KO/src/mastercontrol.h:22,
                 from ../KO/src/kocam.h:22,
                 from ../KO/src/game.cpp:19:
/usr/local/include/Dry/Physics/PhysicsWorld.h:33:10: fatal error: Bullet/LinearMath/btIDebugDraw.h: No such file or directory

This might be an error of my Xubuntu rather than of KO. But I don't know. Maybe you have this error, too?

Greetings

I don't think I've seen this error before, and no idea where it stems from.

Peter

魔大农 Ok I have the vague feeling this is caused by my Linux system. I will try to fix that.

Peter

OK I installed a "new" (re-installed) Xubuntu and tried it there. But the same result. During the installation process several header files are missing, for example from SDL.

Peter But Dry builds fine?

Peter

Yes. I built and installed it from the Dry repo.

Edit: The Dry build inside of the KO repo works fine, too.

魔大农

Peter What about other projects, like heXon, LucKey Park or Open Saucer?

Peter

heXon: Builds completely (running "install", not "install.sh") without errors, but running it gives the following error:
ERROR: Failed to add resource path 'Resources', check the documentation on how to set the 'resource prefix path'

And Park doesn't build:

make
g++ -c -pipe -std=c++11 -O2 -O2 -Wall -W -fPIC  -I. -Icyberplasm/include -IDry/include -IDry/include/Dry/ThirdParty -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++ -o airplane.o src/airplane.cpp

                 from src/world.h:5,
                 from src/airplane.cpp:2:

   26 | #include <../Container/HashMap.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:528: airplane.o] Error 1

OpenSaucer: I don't know how to build it.

Peter Ah, so heXon builds.
cd heXonBuildTree; ln -s heXonRoot/Resources should fix that error. When no Resources folder can be found next to the binary, it will look for them in the application preferences directory, e.g. ~/.local/share/luckey/hexon.

The Field has now been removed (unused, might rewrite later) from Dry:git pull on the engine (and rebuild to rid it from the include) should get you further with LucKey Park.

What's different about Open Saucer that it leaves you clueless?

Peter

魔大农 What's different about Open Saucer that it leaves you clueless?

I have no makefile, install script, install instructions in readme or cmake file or autotools file.

魔大农 cd heXonBuildTree; ln -s heXonRoot/Resources should fix that error. When no Resources folder can be found next to the binary, it will look for them in the application preferences directory, e.g. ~/.local/share/luckey/hexon.

I don't know how to do that. There are no directories heXonBuildTree and heXonRoot. Copying the Resources directory to ~/.local/share/luckey/hexon didn't help.

魔大农

Peter Open Saucer should work the same with a different project name. The .pri file provides the required linkage, which can be found in the src folder.

"heXonBuildTree" and "heXonRoot" should not be taken litteraly:

With heXonBuildTree I actually mean the folder the binary is run from
With heXonRoot I mean the folder you git cloned it to

The command ln -s PATH creates a symlink to PATH within the current folder.

Peter

Ah, it's that simple! 🙂

I am in the git main dir when I type hexon. And there already is the directory "Resources". (I don't know where the executable "hexon" is.)

I can't find a .pri file in OpenSaucer/src. Edit: I tried "qmake OpenSaucer.pro". That seems to work. But now I get:

/usr/local/include/Dry/Physics/PhysicsWorld.h:33:10: fatal error: Bullet/LinearMath/btIDebugDraw.h: No such file or directory

魔大农

Peter When heXon can't find a folder called Resources it will (in my case) use ~/.local/share/luckey/hexon/ as it's resource folder; not a subdirectory. The location of the application preferences directory (~/.local/share/) may differ. Try locate luckey/logs and see what it returns.

Hm, so same error for Open Saucer as KO.
Did you try building LucKey Park again? If it gives the same error I'll see how I can make these projects more like heXon.

Peter

Cloned Park again and tried to build it. Got this error:
/usr/local/include/Dry/Container/Field.h:26:10: fatal error: ../Container/HashMap.h: No such file or directory

魔大农

Peter As mentioned the relevant change there was made to the engine, not the game: A git pull within the Dry folder and recompiling it should solve this issue.

Peter

OK, I didn't understand that. I will try that.

Sorry, but now I get:
/usr/local/include/Dry/Input/InputConstants.h:32:10: fatal error: SDL/SDL_gamecontroller.h: No such file or directory

Peter

bump

I added the error message to my last posting.

魔大农

Peter Well that's a lot of errors all over the place which I'm not experiencing. If you have any ideas on how to improve this situation I'd be happy to follow your advice and/or merge your efforts.

Peter

魔大农 Well, if you don't experience these errors I suspect that's something related to my distro. I don't know; it's just a guess. I think the problem with many headers not found means either the build scripts or the distro has bugs. Do you use Ubuntu, like I do? And which version?

Tomorrow I'll buy DVD-Rs and then I try out Manjaro. I am unsatisfied by my Xubuntu anyway.

Greetings

Peter Environments differ, but heXon builds. One difference I noticed is that heXon does not include Dry/Dry.h anywhere, maybe it's causing conflicts. I modified Open Saucer so it doesn't include it either. Could you try one more git pull and see if it builds now? You may have to clean the build folder.

I run 64-bit Linux Mint Una, Xfce edition. Also, I tend to install Linux from a USB flash drive using mintstick. In Xubuntu you can install usb-creator-gtk which does the same.
Thanks again for your time and efforts.

When you feel like testing again, I still wonder if the latest Open Saucer builds for you.
