I'm building a pure 64 bit instance of the current dev version of LFS, and in chapter 6 it calls the tests for gcc critical - and I'm getting a lot of unexpected failures in the gcc test suite - I've pasted an abstract down below.
The failures are all time outs around the cilk functionality. The virtualbox vm I'm building on is running a clean install of Ubuntu 15.04 server (no ui), with 1G ram, one cpu ( it's an Ivy Bridge Intel i3320m) Is this OK, or am I wasting my time going forward from here? --Larry root:/sources/gcc-build# ../gcc-5.1.0/contrib/test_summary | more cat <<'EOF' | LAST_UPDATED: Obtained from SVN: tags/gcc_5_1_0_release revision 222317 Native configuration is x86_64-unknown-linux-gnu === g++ tests === Running target unix WARNING: program timed out.
