unable to link an executable image

Thanks jofasa,

got it...

with this solution, the elf2flt function will work properly.I try to do the DEBUG Apps " nios2-linux-uclibc-gcc -g hello.c -o hello -elf2flt" again and it should work this time..

do you think this is also the reason why I couldnt run properly the

make gcc elf2flt gdb-host on building the toolchain?

some clarification.. ALL of below should be all in my .bash_profile.. correct?
