[webkit-dev] Error while building webkit on windows

[Baskar CV]

Hi Brent,
Thanks for the reply.
I just checked with the CSSGrammar.y it seems to be fine for for me.
I checked with cygwin too and found grep, flex, and bison installed
Can someone help me on this?


Thanks in advance

Hi,
The problem is with the processing of the CSSGrammar.y file.

Things to check:
1. Is CSSGrammar.y complete? Make sure the checkout didn’t get messed up in some fashion.2. Do you have gperf, flex, and bison installed?  You need flex/bison to process the grammar file and turn it into the stub implementation.

This makes me think that you do NOT have gperf installed. Did you use our Cygwin installer package? Or are you using your own local install?
If you are using your own install from the Cygwin website, you should use the Setup.exe utility and make sure that flex, bison, and gperf are installed.
Thanks,
