Description collette 2009-07-02 13:32:16 UTC 
when flex is not installed, configure detects that flex is not installed but doesn't emit an error.
Flex is required to build gcc-4.5 (to produce gengtype-lex.c).
So, if no flex, no gcc :-)

flex is only required to build svn checkouts or snapshots.  Release tarballs
contain the generated files.
Comment 2 collette 2009-07-02 17:39:02 UTC 
It should be relatively easy to make configure emit an error when it can't find flex. I have lost a couple of hours before figuring out that flex was missing.
