Re: Hello World and 405GP with my gcc cross compiling.

My current position is:

I have no problem for creating the object file, say, HelloWorld.o by
using my gcc for powerpc-elf under a solaris.

And then I moved the object file from solaris to a PC and used the IBM
High c/C++ linker to link my Helloworld.o with the sample "usr_samp"
codes provided by IBM 405GP reference kit. It works fine after being
loaded with the tftp... In other words, it is running on my 405GP
reference board and print out my inserted "hello world..."!

I never had much luck linking GCC generated objects with IBM's High C/C++
linker and libraries.

I think your effort would be better invested if you grabbed the Hard Hard
Linux kernel for the 405GP from MontaVista and set-up an associated NFS
root disk and attempted your development from there.

If you follow the instructions at:

	http://www.borg.umn.edu/~grant/Linux/cross.html

The applications you create will run with Monta Vista's kernel and NFS
root file system.

So, my conclusion is: my gcc for powerpc-elf works, at least for
creating object file part.

Now, why I can't direct creat the executable file but get the above
compain? Looks like it can't find correct libc codes, for example, the
__start and printf symbol and so on.

What my environment is: I used newlib to creat my libc.a. However, I
am not sure if my native gcc use gnulic or newlib. does this matter?

Any clue, folks,
