A typo in step 6: cmake ..\trunk should read cmake ../trunk

Also, trying to install libgl-dev results in this:

Package libgl-dev is a virtual package provided by:

libgl1-mesa-swx11-dev 7.9~git20100924-0ubuntu2 libgl1-mesa-dev 7.9~git20100924-0ubuntu2

You should explicitly select one to install.

So I left it out and tried to build OpenNERO then got these errors:

I've tried libgl1-mesa-dev and also python-wxgtk2.8 instead of wxgtk, build was successful and application seems works OK

For the error noted by Dennis.I.89, the error is actually different - on 64-bit machines, you need to install libpng-dev in order to not get this error.

I'm getting the same error as Dennis.I.89. I have a 64-bit machine. The package libpng-dev is already installed on my computer.

It looks like in your case the error actually talks about libbz2, though I'm not sure where the longer version of your post went:

Linking CXX shared library ../../../dist/libIrrlicht.so
/usr/bin/ld: ../../../dist/libbz2.a(bzlib.c.o): relocation R_X86_64_32S against `BZ2_crc32Table' can not be used when making a shared object; recompile with -fPIC
../../../dist/libbz2.a: could not read symbols: Bad value

I'm getting the same error as Dennis when trying to make:

Linking CXX shared library ../../../dist/libIrrlicht.so
/usr/bin/ld: ../../../dist/libjpeg.a(jcmainct.c.o): relocation R_X86_64_32S against `.text' can not be used when making a shared object; recompile with -fPIC
../../../dist/libjpeg.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [dist/libIrrlicht.so] Error 1
make[1]: *** [external/source/Irrlicht/CMakeFiles/Irrlicht.dir/all] Error 2
make: *** [all] Error 2

I've double and triple checked the libraries you guys mentioned, and they're all installed and up to date. Was this ever officially resolved?

The error in your post is occurring when Irrlicht (which OpenNERO uses for rendering) tries to build its own version of libjpeg unsuccessfully. As with libpng, libgz2 and the others, the workaround for this is to install the development version of these libraries on your system when building OpenNERO. Do do so, use

$ sudo apt-get install libpng-dev libjpeg-dev libbz2-dev

The other part of the workaround is that these libraries have to be installed when running cmake - cmake can fail to notice that they have been installed if you just rerun it. To make sure, delete CMakeCache.txt in the directory you are building in and re-run cmake.

I opened Issue #83 for further tracking of this problem.

Ah, thanks much. I'll post further comments in the Issue 83 thread.

Hi, it may be worth mentioning that you want libpng 1.2. Irrlicht does not compile against 1.5:

For Fedora, the dependency rpms appear to be: boost-devel libX11-devel libXxf86vm-devel mesa-libGL-devel zlib-devel

On ubuntu 10.04 note that the libgl1-mesa-swx11-dev package puts the libraries in /usr/lib/mesa, where the cmake scripts won't find them. I manually added symlinks to /usr/lib, and then cmake seemed happy.

Using Ubuntu 10.10

for MacOSX 10.6, I'm getting an error

Does anyone have any clue?
