Hello,
I’m working on compiling Panda3D in beagleboard with ubuntu9.10 environment(128MB RAM, 1GB swap).
By issueing the ‘./makepanda/makepanda.py --everything’ command at the top of the source directory, the compilation started and it took about 32 hours for me to reach to the following status
[ 92%] Generating ‘pandac’ tree
Importing code library: libpandaexpress
Found extensions for class: Ramfile
[i]bla bla bla
Found extensions form class: OdeBody
[ 92%] Compressing built/models/misc/Dirlight.egg.pz

getcontext failed!

And the build terminated.
For your information, I installed the following packages manually with 'apt-get install' command
[i] gcc, build-essential, bison, flex,
libavutil-dev, libswscale-dev, fftw-dev,
libgl1-mesa-dev, libglu1-mesa-dev, libode-dev,
libopenal-dev, libcv-dev, libtiff4-dev,
libjpeg62-dev, pythod-dev, libxft-dev,
libosmesa6-dev, libpng12-dev, libx11-dev,
libxxf86dga-dev, libxrandr-dev, libavcodec-dev,
libavformat-dev, libopenal-dev, libcvaux-dev[/i]
By googling the 'getcontext failed', I could find little information. :frowning:
Is there anybody having any idea what I should do?
I don’t advise compiling Panda3D on the BeagleBoard itself. It’s a slow process and it doesn’t surprise me that you ran into weird errors. I went through the same process but eventually gave up - and you got a lot further than me.
It’s easier install a cross-compilation toolchain (I got one from CodeSourcery, I used the arm-none-linux-gnueabi one.), and compiling Panda3D on your development (Ubuntu amd64, in my case) machine.
I compiled Panda3D using the ppremake system, as makepanda currently doesn’t support building for EGL / OpenGL ES. I copied various thirdparty packages that I wanted from the beagle to my host system, and stored them in a “tparty” subdirectory in my source. (Be sure to remove /usr/lib, /lib, etc. from your library path before building.)
It will build a libpandagles and libpandagles2. The former is OpenGL ES 1, supports the fixed-function pipeline only. The latter only supports the programmable pipeline, meaning you have to use shaders for everything.
(You can specify which one to use by use of “load-display pandagles” in Config.prc.)
This is the Config.pp I used for the build, it won’t work plug’n’play in your case but it should give you some hints.
It’s been a while since I built for the BeagleBoard myself, so you may run into issues, but I’d be happy to guide you through those.
Alternatively, if all you want is a working Panda3D install that you don’t want to hack with or if you don’t want to go through the painful process of setting this up correctly, let me know and I can make and send you a build.
I should warn you that the process of correctly setting up a cross-compile environment is quite complicated - I’m about to dust off my own panda3d build for the beagle, if you want, I could roll out a build for you.
Thank you for your reply. Since my time is running 9 hours ahead of GMT, I wrote the post last night and found your reply in this morning. Amazing.
Yes, native compiling was very slow, as you mentioned. Since I’m quite new to Panda3D program, I just decided to follow the recommendation in the README file. It said makepanda script is a easier way for a beginner.
Anyway, if you can provide me the .deb file for installation, it would be much helpful for me at this moment. I’m eager to see what it looks like in my beagle board.
BTW, do I have to install the TI providing opengl driver in my beagle board prior to install your build(tarball, deb, whatever…)?
What kind of system are you on? I’m compiling for Ubuntu Lucid myself (as lucid boots quite fast on the beagle) but if you run a different system let me know.
Do you have any special requirements for the build? e.g. threading, OpenCV support, or something like that.
It’s all right. I don’t want to push you at all and I do appreciate your help.
O/S
My current environment for the beagleboard is karmic. I built it up according to the wiki instruction. However, I’ve heard that lucid is faster than others before, too. So, I will move to lucid as you worked.
Third party support
Since I don’t have much experience with Panda3D at this moment, I guess threading and opengl support will be sufficient. However, I would like to run the sample projects in the sample directory after the build/installation. So, if you have some recommendations for the third party functionalities to run particular samples, I will follow your guide.
I’m still fighting to the panda3d native compiling on beagleboard.
Background
I installed ubuntu 10.04 on my beagleboard and installed the following packages additively.
: g++, libjpeg62-dev, libtiff4-dev, libpng12-dev, libopenal-dev, libx11-dev, x11proto-xf86dga-dev, libxxf86dga-dev, libode-dev, libopenal-dev, libfreetype6-dev, libxft-dev, python-dev, automake, libtar-dev, flex, bison
I installed IT SGX SDK package and confirmed that their demo works fine.
My Config.pp are as bellow
ppremake compilation
I compiled ppremake with ‘./configure --prefix=/usr/local/panda3d’ configuration
dtool compilation
I compiled dtool to generate the dtool_config.h file bellow and installed it.
panda compilation
While I compile the panda source, I got the following error

Yeah, sorry that I didn’t manage to get my cross-compilation to work yet - even though I got pretty far. I actually just happened to be trying to compile it this morning, but I ran into glibc incompatibility issues with Ubuntu Lucid’s libpng.
I may set up an automated qemu script soon - but hey, if you can get it working before I do, more power to you.
Did you get the latest CVS version of Panda3D? I think I checked in fixes for the issues you’ve mentioned already.
For the record, OPENGLES is defined in the case of both OpenGL ES 1.x and 2.x. There are individual OPENGLES_1 and OPENGLES_2 macros for those.
It doesn’t support both at the same time - it compiles the same module twice, once with OPENGLES_1 and once with OPENGLES_2 defined.
Yeah - I had these exact same problems when I tried building Panda3D on the beagle board, and then checked fixes to them. So these should be resolved if you make a CVS checkout of the Panda3D sources.
I checked out the latest CVS of panda3d the day before yesterday and compiled.
This time, the previous error did not showed up but I got similar one as follow.

I tracked down the code a little bit, but could not catch up in the middle of many 'ifdef’s and 'ifndef’s.
What should I do next?
Yeah, the ifdefs around that part are a bit confusing. I just checked in a fix - if you call ‘cvs up’ on glGraphicsStateGuardian_src.cxx, it should work fine.

I have two questions at this stage.
Can you tell me what package am I missing?
In case I have to change anything in the Config.pp file, do I have to build up ‘ppremake -> dtool -> panda’ process sequence from the beginning or I just start from dtool and panda build up (‘ppremake; make; make install’ at ‘panda3d/dtool’ directory and ‘ppremake; make; make install’ at ‘panda3d/panda’)?
Either ppremake is messed up and it is building the egldisplay tree before the x11display tree, or you have HAVE_EGL defined but not HAVE_X11, so the x11display tree is not compiled in the first place.
Can you verify that HAVE_X11 is correctly set, and that the ppremake call in dtool detects it?
Also, can you cd into panda/src/x11display and type “ppremake && make clean && make” it, and see if it builds anything? If so, the egldisplay compilation should be able to detect libx11display.
Yes, I defined both HAVE_EGL and HAVE_X11. (You can see my Config.pp file in my previous post.) And, I could build the panda/src/x11display directory locally as you instructed. After building up the library, I went back to panda directory and could successfully finish the compilation. Thank you.
Maybe, there must be some disorder in compilation sequence in ppremake…
I could compile even ‘direct’. However, I got the following error at the ‘pandatool’ compilation.

Do you have any idea on this?
Also, is it O.K. with me to run the samples without this file conversion tool? Since I don’t have a proper LCD monitor at this moment, I could not confirm it for myself. It would take several days to visit my friend’s lab to check it out.
You could easily compile Panda3D without pandatool, no problem. Pandatool is just a collection of model conversion and processing tools, you could just do model conversion on a different machine.
The libegg.so error is a bit disturbing, though. It would seem that it was compiled for a different architecture. Is this on the beagle board, or on your development machine? If the latter, are you sure you’re using a cross-compiling linker?
Oh, and FYI, before I got my HDMI monitor I just used an ordinary TV screen with an s-video to SCART cable. Worked just fine for testing.
I just couldn’t wait until weekend and visited my friend’s lab in the evening.

I do the compilation in the beagleboard. So, it is completely native.
Another error while adding ‘panda3d/lib’ to library path
When I add the lib directory of panda3d using ldconfig, I got the following error.
zooliet@beagleboard:/etc/ld.so.conf.d$ sudo ldconfig
/sbin/ldconfig.real: /usr/local/panda3d/lib/libegg.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/libpnmimagetypes.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/libdistort.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/libeffects.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/libpanda.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/libp3openal_audio.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/librecorder.so is not an ELF file - it has the wrong magic bytes at the start.
/sbin/ldconfig.real: /usr/local/panda3d/lib/libcftalk.so is not an ELF file - it has the wrong magic bytes at the start.
Considering the two symptoms above and the compile error message during the pandatool compilation, I am a bit suspicious if there is;
Any hardcoded parts in the files above that specifing the file format as X86 based one
Any compilation options that do similar.
Of course, when I run ‘pview’, it won’t run and complains that it cannot find ‘libpnmimagetypes.so’ file.
Hm, that’s really curious. I wonder if either one of those libraries is linked incorrectly, or if ldconfig is just expecting the wrong kind of libraries.
