Cross Compiling problems

In short, I'm trying to get EPICS ported to linux over NiosII. The folks at Argonne National lab already have EPICS running on linux over x86 architectures. Among the many cross compiling probl...

Ken,

Thanks for the feed back.

I am running from the command line, but I'm not working on my Kernel right now. I'm trying to get this application built to run on linux over Nios.

What I meant by "-S" was my compiler flag.

nios2-elf-gcc -S foo.c, instead of nios2-elf-gcc -c foo.c

The compiler was passing the assembly file to the HOST assembler. By using "-S," I was able to generate the assembly file "foo.s," then call nios2-elf-as direclty and generate the object file.

I'm now over this hurdle. I updated GCC_EXEC_PREFIX with the correct path to cc1, and cc1plus. I was also calling nios2-elf-gcc, when I needed to be calling nios2-elf-g++. A cut, copy, and paste error!!!

The assembler is happy now that I'm calling the correct one. And for about 2 minutes, so was I. The flavor of the afternoon is with basic_string.h being called out of the ....../c++/3.4.1/bits/ directory.

I'm getting errors like '_Atomic_word' does not name a type, and

'__exchange_and_add' is not a member of '__gnu_cxx'
