Before these errors, I overcome the error below: 

gcc: c-parse.c: No such file or directory gcc: no input files make: *** Error 1 make: Leaving directory `/nios2-linux/toolchain-build/build/gcc-bootstrap-build/gcc' make: *** Error 2 make: Leaving directory `/nios2-linux/toolchain-build/build/gcc-bootstrap-build' make: *** [/nios2-linux/toolchain-build/bui   by doing what Magog said   --- Quote Start ---   We had the same problem. It can be solved by modifying file nios2-linux/gcc3/gcc/c-parse.y. From the line 1650, 1661, 1670 and 1675 modify $$ to $<ttype>$. For example change the line 1650 from { $$ = start_struct (RECORD_TYPE, $2); to { $<ttype>$ = start_struct (RECORD_TYPE, $2);   --- Quote End ---   in http://www.alteraforum.com/forum/showthread.php?t=22528
