[mapserver-users] SOLVED: MS 3.5 PHP3 MapScript Install

[Stephen Woodbridge]

Dan,

I finially got this to install. I could not get the instructions on
dmsolutions.ca site to work so you might want to try them yourself.

Here is what did work.

Redhat 6.2 with Linux 2.2.18
apache_1.3.22
php-3.0.18
mapserver 3.5 released code

I configured apache with:
./configure \
--enable-module=all \
--enable-shared=max \
--with-layout=RedHat

I configured php3 with:
# PHP must be configured --without-ttf because we are using a
# conflicting version in MapScript! see:
#
http://www2.dmsolutions.ca/mapserver/php_mapscript/php_mapscript_faq.html#4.4

./configure \
--prefix=/usr \
--with-apxs=/usr/sbin/apxs \
--with-config-file-path=/etc/httpd \
--enable-safe-mode \
--enable-versioning \
--enable-force-cgi-redirect=yes \
--enable-discard-path=yes \
--with-exec-dir=/usr/bin \
--with-system-regex \
--disable-debug \
--with-zlib \
--with-gdbm \
--enable-debugger \
--enable-magic-quotes \
--enable-track-vars \
--enable-sysvsem \
--enable-sysvshm \
--enable-track-vars \
--with-xml \
--with-ftp \
--with-jpeg \
--without-ttf \
--with-gd \
--with-mysql=/usr

When you run make the last command to execute is /usr/sbin/apxs which
echos two lines starting with gcc. The first is to complie mod_php3.c
and the second is the important one which links libphp3.so as a shared
object. Unfortunately, the APXS command does NOT use the LDFLAGS
variable.

My fix was to copy the last line of output (in my case):

gcc -shared -o libphp3.so mod_php3.o libmodphp3-so.a -L/usr/local/lib
-lpng -lz -ljpeg -lgd -L/usr/lib/mysql -lmysqlclient -lgdbm -lz -lgdbm
-lpam -ldl -lcrypt -ljpeg -lttf -lpng -lgd -lresolv
-Wl,--version-script=/home/woodbri/linux/php-3.0.18/php.map -Wl,-rpath
/usr/lib/mysql

and added -rdynamic in front of -shared  (THIS DID NOT WORK)
so I tried -export-dynamic (THIS DID WORK):

gcc -export-dynamic -shared -o libphp3.so mod_php3.o libmodphp3-so.a
-L/usr/local/lib -lpng -lz -ljpeg -lgd -L/usr/lib/mysql -lmysqlclient
-lgdbm -lz -lgdbm -lpam -ldl -lcrypt -ljpeg -lttf -lpng -lgd -lresolv
-Wl,--version-script=/home/woodbri/linux/php-3.0.18/php.map -Wl,-rpath
/usr/lib/mysql

I then su; make install; and restarted apache and the
phpinfo_mapscript.php3 script works and shows the MapScript config info.

The strange thing with php3 is that I removed the -shared from LDFLAGS
and did a make clean; make > log then check for "shared" and it only
shows up in the APXS command which means that LDFLAGS is not being used
by the make all targets.

I hope this helps someone else.
