who can help me save my memory?

Our nios2linux Cross Compiler:

1. bin files from Altera nios2 tools CD under redhat , and we copied them to proper directories.

2. build some nessary tools according "hippo_mini_nios2linux",such as elf2flt

3. modify config.arch to export CROSS_COMPILE, CC...

So we guess there are some mistakes happens.

Here we copy our modified config.arch

there is one big difference:

we find that "-elf2flt" in LDFLAGS has no effect in original Makefile, so we modified Makefile to ELF2FLT explicitly in one step according to Microtronix's did in Nios2IDE.

here are messages in compling:
