But I have not been able to set up a working Cygwin build environment, so I can't try to rebuild it right now. It sure looks like it's the exec that's failing. cheers andrew -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Can you let me have the flex.exe and cygwin1.dll that I can try on a virgin WinS2k3 64-bit box? It will probably need to be configured with --disable-nls. cheers andrew -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

This is the version I am using (probably not newest one or anything, but I used it for testing all of my patches for 8.5 and I tried it successfully today on git head). http://pjmodos.parba.cz/temp/cygflex.zip -- Regards Petr Jelinek (PJMODOS) -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
