I made some progress with the Problem, linking of the pthead-lib is not correctly done by G++. I managed to improve the situation describe by Hag by adding the path to the pthread.a to the linker command.

It looks like this: 


nios2-linux-c++ -o ijpis -elf2flt="-s 65536" include/tinyxml.o include/tinyxmlparser.o include/tinyxmlerror.o include/tinystr.o opt/nios2/lib/libpthread.a

After that, it is able to link the invocation of pthread_join() and the objectdumb shows: 


0001b170 g     F .text	0000010c pthread_create

The situation is improved, but after starting the program it still hangs after pthread_create...

A note at the end: I use the gcc version 3.4.6. I haven't tried to use another, yet.

Best regards
