Dependencies when using gcc-generated object files in another compiler

Fri Dec 15 10:16:00 GMT 2006

Hi,
I am working on including java-code into an self-written operating system. The used tool chain is a Greenhills one, but it is not able to translate java to native code. For this reason I am using gcj to translate my java code to native mips code and then link with Greenhills the whole project. But the linker complains, as expected, about unresolved symbols, even when I include all the archives from the libs dir of my cross compiler. The Problem is I have no idea, where I could search for the rest of the objects I need. Perhaps someone could tell me if gcc searches somewhere else too for libs when cross compiling.
