• Update url location in XML
• Now requires Bison to build.
  1. Swap the build order of Bison and Flex in the final-system
     • Will be test suite failures for Bison due to the absence of Flex
  2. Add Bison to /tools
     • Flex doesn't appear to store the location for the Bison executable in its installed files so there shouldn't be any problems.

For Ch 6 Option of installing Bison:

• Unsure if we'll need 32-bit and 64-bit for multilib

  ./configure \
      --prefix=/tools \
      --build=${CLFS_HOST} \
      --host=${CLFS_TARGET}
  make
  make install
  

For Ch 10

• Check if M4=m4 is required in Ch 10 when installing Bison during Ch 6
• Use the following instead of a wrapper script:

  ln -sv flex /usr/bin/lex

I've tried putting Bison into /tools - Flex still failed. I think it needs libraries from Bison, so the best solution would still be to swap Flex and Bison in the final-system, and add a note to the Bison page that some tests will fail due to Flex's absence.

I put Bison into /tools and then built Flex with no problems and passed all it's tests, this is with a GCC-5.3.0 toolchain. However previously it didn't work on many tries before when building GCC snapshots this way. My suspect is/was a library linking problem with libstdc++, I've been removing .la files from the build as i go with redundant static libs and seems to be cleaner.
