" The default compiler is nios2-elf-gcc, which comes with nios2eds. If you want to use nios2-linux-gnu-gcc to build u-boot, you may set, " I dont change the compiler to the "nios2-linux-gnu-" "nios2-linux-uclibc-"only use the "nios2-elf-gcc" compiler, then run like this " make my_nios2_config "
# make my_nios2_config

Is nios2-linux-uclibc-gcc instead of the nios2-elf-gcc compiler to be the default compiler in the nios2-linux-20100621 tarball ?
# nios2-linux-uclibc-gcc -v

gcc version 3.4.6
Does it mean using the "nios2-linux-uclibc" is right, "nios2-elf-gcc" is wrong ? PS: I use the "nios2-linux-uclibc"compiler compiling the u-boot successfully,but there's no u-boot.elf file! Using the "nios2-elf-gcc" compiler maybe generates the u-boot.elf?
