Re: Failure to make grap 1.30 under cygwin 1.5.5

Fergus,

This is a general Cygwin question, not a Cygwin/XFree86 question.  It 
should have been sent to cygwin@cygwin.com, not cygwin-xfree@cygwin.com.

However, I happen to know the answer you want to hear.  The problem is 
that 'flex' 2.5.31-1 sucks; it can't build anything in the XFree86 tree. 
 Something is horribly wrong with it, but I don't care to get involved 
in fixing it.  As such, I have upgraded flex to the 'test' version 
2.5.4-2.  You can do this in Cygwin's setup.exe, but you have to keep 
manually reselecting that version each time you run setup.exe because it 
will always try to replace it with the 'curr' 2.5.31-1 version.

Good luck, I hope that helps,

Harold
