Linking errors

[Matthias Hofmann]

Hello,

i use a crosscompiler toolchain for compiling and linking programs from
cygwin to linux.
Currently, i try to figure out some informations about the following
linking errors, but i did not had any succes yet.

Linking...

what does these error messages mean? any suggestions how to fix them?
compiling and linking an other programs works well.

thank you very much,
