Hi Gael,

Indeed, gdbserver does not support Solaris.  In an ideal world, 
gdbserver would support all the configurations of architectures and OSes 
that GDB supports, but in reality it's not the case.

For gdbserver to support Sparc/Solaris, someone would need to do the 
work of extracting the Sparc and Solaris bits out of GDB in the arch/ 
and nat/ directories, and then re-use that to implement the support in 
gdbserver.  I would love to see this happening, but to be honest I don't 
think someone will randomly jump on that task.  Generally, people 
contribute to the support of architectures and OSes they use, and I 
don't think many people use Sparc/Solaris these days.  If you would like 
to give it a shot, we we'll happily answer your questions (here or on 
IRC).
