Hi, I am trying to run gcc-4.4.5 testsuite , but everytime i run it, i got lots of failure e.g unexpected failures 13000 My configuration:- In my pc latest version of gcc-4.8 is install and i want to configure and run gcc testsuite for gcc-4.4.5 Ubuntu 14.04 Host = x86_64-linux-gnu Build = x86_64-linux-gnu Target = powerpc-linux-gnu These are the steps which i performed to run testsuite 1. I am trying to run configure with this script sourcedir.../gcc-4.4.5/configure --prefix=/tmp/gcc-4.4.5 --enable-languages=c,c++ --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=powerpc-linux-gnu --enable-languages=c,c++ --enable-long-long 2. And then to build gcc :- make all-gcc 3. To run the testsuite :- sourcedir.../gcc-4.4.5/gcc make check It generates lot of failures Dejagnu :- latest version Thanks & regards Mappy
