Building bootimage fails on linux using riscv-gcc 5.3.0 #2

Closed bkoppelmann closed 8 years ago

When running make to build the bootimage I get the following error:

Changing the CFLAGS back to -O2 seems to fix the problem.

Most probably you're using mixed glibc libraries for soft-float and hard-float platforms. They are not binary compatible. Use gcc 5.1.0 toolchain that is available by link on main page of the repository.
