[mapserver-users] 3.5 build problem

[Daniel Morissette]

Stephen,

It seems that you have 2 versions of regex installed on your system: the
default system regex in /usr/lib, and rxposix in /usr/local/...

The problem is that MapServer only cares about the system regex (and
regex.h), but libwww which is used by the --with-wmsclient does detect
your rxposix.h and use it in priority over regex.h if it's found... and
then you end up with conflicting declarations.

I don't think there is a nice and easy fix... here are some options:

1- Remove rxposix from your system and recompile libwww and the conflict
will go away.

2- Make MapServer aware of rxposix... we may do that down the road, but
I suspect that this will have implications with PHP as well, so I won't
do that now.  I filed a bug about this and might make that change
eventually: http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=82

3- Try playing with libwww's --with-regex configure option to try to
force it to use the system regex in priority.  If that doesn't work then
edit libwww's configure.in to remove rxposix.h in the line that reads:
  AC_CHECK_HEADERS(rxposix.h regex.h)
... then run autoconf and reconfigure.

I hope that helps,

Daniel
