[Solved] Install CEED on ubuntu. Problems with PyCEGUI

[nao]

Hi.

I trying to install CEED/CEGUI on ubuntu but I get a sigfault. Here my steps:

Read http://cegui.org.uk/wiki/CEED. After that I did:

Code: Select all

hg clone https://bitbucket.org/cegui/cegui
hg clone https://bitbucket.org/cegui/ceed
cd ceed
hg update v0-8
cd ../
cd cegui
hg update v0-8
cd ../
mkdir cegui/build
cd cegui/build
cmake -DCEGUI_BUILD_PYTHON_MODULES=ON -DCEGUI_BUILD_RENDERER_OPENGL=ON -DCEGUI_BUILD_RENDERER_OPENGL3=ON ../

And then:

Code: Select all

cd ../ceed
cd bin
./runwrapper.sh
./ceed-gui

It doesn't works because of the cd .., so I did:

Code: Select all

cd ../../ceed
cd bin
./runwrapper.sh
./ceed-gui

Still doesn't work so I tried a little bit more I went to the folder cegui/build previously created and i did "make".

Then I tried again but I got:

/usr/lib/python2.7/dist-packages/cegui-0.8
Following problems found:
PyCEGUI package is missing! PyCEGUI provides Python bindings for CEGUI, the library this editor edits assets for, see cegui.org.uk. (exception: No module named PyCEGUI)
Your environment doesn't meet critical prerequisites! Can't start!

After that I edited the runwrapper.sh and I changed

Code: Select all

CEGUI_BUILD_PATH="$PARENT_DIR/../../cegui-v0-8"

by

Code: Select all

CEGUI_BUILD_PATH="$PARENT_DIR/../../cegui"

And then I get the segment fault. I had a look at prerequisites.py and it's just when it try to do __import__("PyCEGUI")

I have read the followings links but without success , any ideas?

PS.1: I'm on ubuntu 14.04 32bits with these dependences:

Code: Select all

cmake python-opengl pyside-tools libboost-python-dev libboost-python1.54.0 libboost-python1.54-dev

there isn't

Code: Select all

 boost-python

on my system.

PS.2: I don't get any error after cmake or make.

PS.3: If I don't change the runwrapper.sh and i put PyCEGUI.so in the same folder as ceed-gui, I get the same segment fault.

Thanks.

You need to call 'make' after you called CMake:

Code: Select all

[...]
mkdir cegui/build
cd cegui/build
cmake -DCEGUI_BUILD_PYTHON_MODULES=ON -DCEGUI_BUILD_RENDERER_OPENGL=ON -DCEGUI_BUILD_RENDERER_OPENGL3=ON ../

make -j4

[...]

Thank you lucebac but actually I did it.

Still doesn't work so I tried a little bit more I went to the folder cegui/build previously created and i did "make".

My post is so long and maybe you didn't notice it. the only difference is that I used make instead of make -j4

[TheSHEEEP]

The make "-jX" command is just a command to allow parallel building.
-j4, for example will use 4 threads for that. Makes building a lot faster.
And using only "-j" will allow the building to use as many threads as it wants (not sure what is the limit there), which can really slow down your machine.

Do you have python3 installed? There is a well known issue with CMake/FindPython finding the wrong python paths it happens to me on Ubuntu. It shouldn't seg fault but you never know.

If so did you check that you that the build is not picking up the wrong version of python? Go to the /cegui/build dir and either double click on CMakeCache.txt and check via the cmage-gui or open CMakeCache.txt and check the paths for PYTHON_INCLUDE_DIR etc. You can pass the correct paths via the command line as per one of the links you provided.

Otherwise got to the cegui/build/lib dir and see if you can import the modules manually.

Hi. No, I don't have python 3 but after trying to import manually a get:

Code: Select all

I guess that's a problem with boost. I started again so see if there is something missing. I see two lines related to boost. What do you think?:

It looks like boost python developers package isn't installed. I just looked at your commands again you should be running apt not cmake and install libglfw-dev as well you may need that to ensure the OpenGL module is built and the OpenGL demos run.

Code: Select all

###cmake python-opengl pyside-tools libboost-python-dev libboost-python1.54.0 libboost-python1.54-dev
sudo apt-get install python-opengl pyside-tools libboost-python-dev libboost-python1.54.0 libboost-python1.54-dev libglfw-dev


Edit: maybe also check you have the boost headers install /usr/include/boost - libboos1.54-dev.

[dermont]

Also run your cmake command with boost debug to see exactly what is being searched for and post the results.

Code: Select all

cmake -DCEGUI_BUILD_PYTHON_MODULES=ON -DCEGUI_BUILD_RENDERER_OPENGL=ON -DCEGUI_BUILD_RENDERER_OPENGL3=ON -DBoost_DEBUG:BOOL=ON ../


Also double check you have libpythonX.X-dev installed for whatever version python you are running.

Edit you'll probably need libglm-dev for the OpenGL renderer and a xml parser such as libexpat1-dev / libxml2-dev / libexpat1-dev or xerces if you don't already have one installed.

When I wrote that my dependences are

Code: Select all

cmake python-opengl pyside-tools libboost-python-dev libboost-python1.54.0 libboost-python1.54-dev

I meant cmake was one of them.

I did what you said, I installed libglfw-dev and also libboost-dev. I already had libpython2.7-dev, libglm-dev, libexpat1-dev and libxerces-c-dev but not libxml2-dev

Now it seems to work. I try and then I'll let you know if everything is working.

[nao]

It works!

Thank you dermont!

I mark the thread as solved.

Yeah, sorry about that I didn't read your original post post properly. Anyway glad you got it sorted.
