Bug 66087

Version:            (using KDE KDE 3.1.3)
Installed from:    Solaris Packages
Compiler:          SunProCC (Forte 7) : CC: Forte Developer 7 C++ 5.4 Patch 111715-09 2003/06/24 
OS:          Solaris

Hi

This bug has been reported several times, on different OS/Compiler combinations, but i believe this is the first time it's been reported on Solaris (SunOS 8) 32-bit.

Engine::initArts() fails when trying to instantiate a Noatun::Session object:

file kdemultimedia/noatun/library/engine.cpp:
Arts::Object session = d->server.createObject("Noatun::Session");
if (d->session.isNull())
{
    kdWarning() << "Couldn't instanciate artsobject Noatun::Session. "
// ... [snip]

This bug also exists in KDE 3.1, 3.1.1 and 3.1.2, also on SunOS 5.8 with the same (Forte 7) compiler.

It can be easily reproduced in the Solaris packages available for download at KDE.

It has also been reproduced on SunOS 5.8 (Solaris 8) with gcc3 (gcc3.3,REV=2003.07.22) at blastwave.org.

Incidentally, trying to instantiate an Arts::Synth_STEREO_COMPRESSOR (as seen in the test case enclosed below) also fails.

Here is the stack trace output from running Noatun inside dbx:

noatun: WARNING: Couldn't instanciate artsobject Noatun::Session. (This is normally caused by a broken package or compiling kdemultimedia in a --prefix different from arts.  It may also be from two conflicting packages, so uninstall every arts/artsd package you have installed and try againe.

This is probably not very useful, but it's the best i can get with optimized packages. :-)

Please let me know if i can be of any help.

I am enclosing a small test case which shows the exact same behavior.

Thank you!
