help with eclipse warning "error launching external scanner info generator"


i'm run into a eclipse error which i'm not able to solve myself on a fresh ubuntu/eclipse install.

i'm running ubuntu 11.10 with eclipse helios and self-compiled toolchain.

PATH variable is set in linux. i also tried setting PATH variable in eclipse... but also no success...

when i start a new project... i.e. simple hello world from doc, eclipse put warnings and i'm not able to compile (guess it's because eclipse cannot find the symbols)

the displayed warnings are

Error launching external scanner info generator (bfin-linux-uclibc-gcc -E -P -v -dD /home/pez3/workspace/.metadata/.plugins/org.eclipse.cdt.make.core/specs.c)

don't know howto solve it...

if i run this command via console i don't get any error, warning, etc.

can anybody help me here?

thank you

greets peter
