Since 'make' finished without error, you may now proceed to run the testsuite. Suggestion: Increase the stack size prior to running the tests using the following command: $ ulimit -s 32768 Then, run the tests using the command below: $ make -j 2 -k check 'make -j 2' is for parallel build. Replace '2' with the number of processor cores available on your system. Currently, the gcc 4.9.1 'c' compiler executable for your build will be in 'objdir/gcc' with name 'xgcc'. In your case, exactly in the folder '/home/david/scratch2/objdir/gcc'. The path you specify in '--prefix=<path>' is the installation path for the toolchain. After the successful build of the toolchain, you can install it using the command below: $ make install All executables will be installed in '<path>/bin', where <path> is the folder specified in --prefix. Also, directories 'lib' for libraries and 'include' for header files will be created appropriately in <path>. Hope, this clarifies. Best Regards, Raghunath Lolur.
