[eq-dev] Equalizer on Ubuntu 13.04

[Simon]

Hello everybody,

Unfortunatly I'm unsuccessfull to compile a project using equalizer that has
compiled on Ubuntu 12.10 on Ubuntu 13.04.

On 12.10 I easily could install using your PPA
https://launchpad.net/~eilemann/+archive/equalizer/.
On 13.04 it does not work anymore, saying equalizer140 was not found.
Do you offer Equalizer for Ubuntu 13.04?

My second try was to compile equalizer by myself, but I got some weird cmake
problems.
When I cmake everything goes fine until this:

-- checking for module 'hwloc>=1.3'
-- package 'hwloc>=1.3' not found
-- Could NOT find osgDB (missing: OSGDB_LIBRARY OSGDB_INCLUDE_DIR)
-- Could NOT find osgUtil (missing: OSGUTIL_LIBRARY OSGUTIL_INCLUDE_DIR)
-- Could NOT find osg (missing: OSG_LIBRARY OSG_INCLUDE_DIR)
-- Could NOT find OpenThreads (missing: OPENTHREADS_LIBRARY
OPENTHREADS_INCLUDE_DIR)
-- Could NOT find OpenSceneGraph (missing: OPENSCENEGRAPH_LIBRARIES
OPENSCENEGRAPH_INCLUDE_DIR) (Required is at least version "3.0")

Full:
http://pastebin.com/TeUGcfxk

The strange is that I have installed hwloc and openscenegraph using apt-get
install.

I can make and make install Equalizer without those packages. (I do not use
openscenegraph in the project so its ok).

When I generate my Project, cmake finds Equalizer Version 1.5.1.

When I try to build and run the project the compiler gets two problems that
did not come on Ubuntu 12.10 using Equalizer 1.4.1.

The Code is:

void InitData::getInstanceData(co::DataOStream &os)
{
os.write(&data, sizeof(data));
os << _nodeNames;
os << _types;
os << _positions_x;
os << _positions_y;
os << _positions_z;
...
}
void InitData::applyInstanceData(co::DataIStream &is)
{
is.read(&data, sizeof(data));
is >> _nodeNames;
is >> _types;
is >> _positions_x;
is >> _positions_y;
is >> _positions_z;
...
}

And the erros the compiler throws are:

/home/simon/myProject/src/initdata.cpp:22:12: error: 'class co::DataOStream'
has no member named 'write'
/home/simon/myProject/src/initdata.cpp: In member function 'virtual void
vr::InitData::applyInstanceData(co::DataIStream&)':
/home/simon/myProject/src/initdata.cpp:43:12: error: 'class co::DataIStream'
has no member named 'read'

I checked out the current git branch. I would like to try to build Equalizer
1.4.1, because this version worked with the project.
But git gives me 1.5.1 and the site gives me 1.3.6.

Thanks in advance for any help.

Simon

Equalizer 1.4 predates Ubuntu 13.04. I can try uploading a source package on Monday, though that might not work. In any case, we'll release Equalizer 1.6 in a couple of weeks.

Don't worry, they are optional dependencies. Equalizer will compile without them at slightly reduced functionality.

Ah. :)

Made co::DataIStream::read private. Use 'is >> co::Array< T >( ptr, num )'
instead.

The same applies to write().

git checkout 1.4


HTH,
