Hello,everyone!
i have a problem when I install the toolchain ! when i do this step(./bld-all.sh --force --prefix /opt/openrisc/openrisc --or1ksim-dir /opt/openrisc/or1ksim --uclibc-dir uClibc --linux-dir linux ),the compilation explain that libsim.a is incompatible.I don't know how to solve it!
My platform : ubuntu12.04 gcc4.4.7

gcc -DHAVE_CONFIG_H -DPROFILE=1 -DWITH_PROFILE=-1 -DDEFAULT_INLINE=0 -I/opt/openrisc/or1ksim/include -I. -I../../.././gdb-7.2/sim/or32 -I../common -I../../.././gdb-7.2/sim/or32/../common -I../../include -I../../.././gdb-7.2/sim/or32/../../include -I../../bfd -I../../.././gdb-7.2/sim/or32/../../bfd -I../../opcodes -I../../.././gdb-7.2/sim/or32/../../opcodes -g -O2 -o run \

Hi,

did you build and install or1ksim as explained in the Prerequisites here: http://opencores.org/openrisc,gnu_toolchain ?

Franck.

Thank you,Frank!
I'm a new bird to study or1200,so I will have a lot of problems. Now I compiled the or1ksim ,and the problem of or1ksim has been solved .But now i have another probelm.

I have the stdio.h in /usr/include/
iI don't know why.
thanks!

I used orbuild and successfully installed the GNU toolchain in Ubuntu 12.04 (gcc 4.6.3)
