buildroot to build toolchain on Linux

hi nippo

I can find nios2-linux-uclibc-gcc in ~/buildroot/build_nios2/staging_dir/bin dir and check the "PATH=$PATH:/buildroot/build_nios2/staging_dir/bin" follow.

[jay@localhost ~]$ cd ~/buildroot/build_nios2/staging_dir/bin

[jay@localhost bin]$ ls

bash: nios2-linux-uclibc-gcc: command not found

Occur the same question again.
