nios2-gcc ld cannot open crt0.o after recompiling

nios2-gcc ld cannot open crt0.o after recompiling

[Liu Haibin]

Hi,

I recompiled the nios2-gcc on cygwin and got an error when I executed

#cd /usr/local/bin
#./nios2-elf-gcc.exe -v t.c

But when I used the original nios2-gcc, everything was ok.

#cd /cygdrive/c/altera/kits/nios2/bin/nios2-gnutools/H-i686-pc-cygwin/bin
#./nios2-elf-gcc.exe -v t.c

I'm very confused here. Why does the recompiled nios2-gcc try to use
ld while the original one doesn't (at least doesn't explicitly use it
with -v option) ? How can I solve the problem here? Thanks.
