when I do make rtl-tests in sim/run dir, the error like this:

Hi iayowu

I think you may have a tool chain incompatibility. It looks like the tests are now designed to use the latest version of the GCC compiler, gcc 4.5.1. Do you have this installed (if not, see the OpenRISC GNU tool chain page for details of how to install the release candidate tool chain).

Julius Baxter may be able to give more advice on this - you could try asking him on IRC at freenode.net, channel #opencores

Software included with ORPSoC now requires the more recent toolchain to compile.

See the release candidate toolchain install script (on the GNU toolchain page: http://opencores.org/openrisc,gnu_toolchain#1.0rc1install ) to get a version of GCC which will compile the software in ORPSoC OK.

I can't do 'yum install libmpc libmpc-devel' in my CentOS5.4, so I install the gmp-4.3.2, mpfr-2.4.2 and mpc-0.8.1 manually.

and changed build script crossbuild-1.0.sh like this:
-or32configure="--disable-checking --enable-fast-install=N/A --disable-libssp --enable-languages=c,c++ --with-or1ksim=$prefix/or1ksim --with-newlib"
+or32configure="--disable-checking --enable-fast-install=N/A --disable-libssp --enable-languages=c,c++ --with-or1ksim=$prefix/or1ksim --with-newlib --with-gmp=/usr/local/gmp-4.3.2 --with-mpfr=/usr/local/mpfr-2.4.2 --with-mpc=/usr/local/mpc-0.8.1"

but have another problem :
configure:5841: checking for version 0.10 of PPL
configure:5858: gcc -c -g -O2 -I/usr/local/gmp-4.3.2/include -I/usr/local/mpfr-2.4.2/include -I/usr/local/mpc-0.8.1/include conftest.c >&5
conftest.c:10:19: error: ppl_c.h: No such file or directory
conftest.c: In function 'main':
conftest.c:16: error: 'choke' undeclared (first use in this function)
conftest.c:16: error: (Each undeclared identifier is reported only once
conftest.c:16: error: for each function it appears in.)
conftest.c:16: error: expected ';' before 'me'

compile toolchian in centos is so hard, I have compiled it in ubuntu smoothly. Can I move it to centos environment?

thanks for your answer to my question.

This is a matter unrelated to ORPSoC, which the thread was initially about. Please start a new thread if you're having separate issues.

But to answer your question, I have installed on CentOS recently (64-bit version) and did the following to install the GMP and MPFR libraries from source:

For GMP:




For MPFR:



I believe I still installed the MPC stuff using yum, I could be wrong though - my bash history didn't go back far enough unfortunately. I definitely did not have to add the --with-gmp= --with-mpc= --with-mpfr= flags when configuring GCC; the script should work unedited.
