Hi all,

sorry for that late response! It took, quite a while to find the solution.

Yes, it is the UMN Mapserver and yes it the php-mapscript part which needs
php to be compiled as a cgi. BTW, I don't get the mapscript-part from
mapserver 4.0 compiled. They changed the php-mapscript Makefile a little,
so that older workarounds don't help anymore. Right, that's for another
list. Sorry :-).

I found out, how get php as cgi running on FreeBSD using ports/www/php-cgi.

To start with: The following lines are required in apache httpd.conf. I
never had something else! Lucas mail with the Windows example showed, that
these entries always were correct and I was able to get that running on a
debian machine:

ScriptAlias /cgi-bin/ /usr/local/www/cgi-bin/
<Directory /usr/local/www/cgi-bin>
    AllowOverride None
    Options ExecCGI
    Order allow,deny
    Allow from all
AddType  application/x-httpd-php .php
Action application/x-httpd-php /cgi-bin/php

I downloaded the original source code and compiled it, having configured
it just with ./configure. I copied the php-binary to
/usr/local/www/cgi-bin and I couldn't believe it, php was running as a
So it was just a thing to find out which option causes this error. It is
the "--enable-discard-path" which is used as a default by
Having compiled php with this option on debian causes the same symptom!

But I want to use ports. I edited the ports/lang/php4 Makefile like this:

CONFIGURE_ARGS= --enable-versioning \
                --enable-force-cgi-redirect \ # recommended for cgi
                --with-regex=system \         # needed by mapserver*
                --enable-memory-limit \
                --with-layout=GNU \
                --with-zlib-dir=/usr \

*Actually the following part would do the same, but I couldn't find out
how to tell 'make' WITH_REGEX_TYPE=system. So I changed the Makefile a
There is another knob 'WITH_LZW' but it's the same problem. I don't know
how to tell 'make' this. Does somebody know?

#.if !defined(WITH_REGEX_TYPE) || ${WITH_REGEX_TYPE} == "php"
#.if ${WITH_REGEX_TYPE} == "system"
#.if ${WITH_REGEX_TYPE} == "apache"

this the major part to get php4-cgi running on FreeBSD:

#.if defined(WITHOUT_APACHE)
#PLIST_SUB+=    APACHE="@comment "

Finally I of course would like know what it's all about 'discard-path' why
does the maintainer Alex Dupres use this as a default and why conflicts my
httpd-configuration with 'discard-path'!?
