Host - Dreamhost
Shared Hosting environment (no root access)
Debian based

The idea is to create a local build area that is completly independent and will not require root access. All applications are installed into that local area through the use of the –prefix option at config time.
The use of RPATH in many instances gets around the need to modify the LD_CONFIG_PATH (or /etc/ld.so.config and /sbin/ldconfig)

Start by creating a build environment under the home directory of the shared host:

/home/racicot/usr /home/racicot/usr/local /home/racicot/etc /home/racicot/etc/httpd /home/racicot/var /home/racicot/var/www /home/racicot/var/www/cgi-bin

Next we start marching through all the installs…

1) Ming (optional)

cd ming-0.3.0 ./configure --prefix=/home/racicot/usr/local make make install
**Don’t forget to add ‘extension=php_ming.so’ to php.ini!

2) Pdflib (optional)

cd PDFlib-Lite-6.0.3 ./configure --prefix=/home/racicot/usr/local make make install

3) Proj.4

cd proj-4.4.9

cd nad/

cp ../../proj-datumgrid-1.3.zip .

unzip proj-datumgrid-1.3.zip

cd ..

./configure --prefix=/home/racicot/usr/local

make

make install

4) GDAL

cd gdal-1.3.1 ./configure --prefix=/home/racicot/usr/local --with-static-proj4=/home/racicot/usr/local/lib --with-local=/home/racicot/usr/local make ogr-all make install

5) GEOS

cd geos-2.2.1 ./configure --prefix=/home/racicot/usr/local make make install

6) READLINE

cd readline-5.1 ./configure --prefix=home/racicot/usr/local make make install

7) POSTGRESQL

NOTE the LDFLAGS here… this is to support GEOS for postGIS
setenv LDFLAGS -lstdc++ ./configure --prefix=/home/racicot/usr/local --with-libs=/home/racicot/usr/local/lib --with-includes=/home/racicot/usr/local/include

############### Had to change the sockets file location to keep the
############### reaper from getting the file in /tmp
edit ~/usr/local/src/postgresql/postgresql-8.1.4/src/include/pg_config_manual.h
< #define DEFAULT_PGSOCKET_DIR "/tmp"
> #define DEFAULT_PGSOCKET_DIR “/home/racicot/tmp”
rebuild….
###############

make make install

Run make install in the ./doc directory to install the documentation

../usr/local/bin/initdb -D /home/racicot/postgresql_data ../usr/local/bin/pg_ctl -D /home/racicot/postgresql_data -l logfile start

Finally add the following to the .cshrc profile file to make paths available:
setenv PATH ${PATH}:/home/racicot/usr/local/bin

Create a new postgres user:

[postgis@localhost pgsql]$ createuser aaronr Shall the new role be a superuser? (y/n) y CREATE ROLE

POSTGIS

Just make sure that the Postgresql is configured with the LDFLAGS variable set
and that the GEOS software is downloaded and installed from Refractions.

./configure --prefix=/home/racicot/usr/local --with-pgsql=/home/racicot/usr/local/bin/pg_config --with-proj=/home/racicot/usr/local --with-geos=/home/racicot/usr/local/bin/geos-config make make install

Now we can create the database:
createdb -O aaronr test_db createlang -U aaronr plpgsql test_db psql -f /home/racicot/usr/local/share/lwpostgis.sql -d test_db

9) PHP

./configure --prefix=/home/racicot/usr/local --enable-force-cgi-redirect --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-tiff-dir=/usr/lib --with-zlib-dir=/usr/lib --with-freetype-dir --without-ttf --with-mysql --with-regex=system --enable-dbase --enable-dbx --enable-versioning --with-config-file-path=/home/racicot/etc/httpd/

make make install

strip sapi/cgi/php cp sapi/cgi/php /home/racicot/var/www/cgi-bin/php.cgi cp php.ini-dist /home/racicot/etc/httpd/php.ini

Made the following mod to /etc/httpd/php.ini:
; Directory in which the loadable extensions (modules) reside.
;extension_dir = “./”
extension_dir = “/home/racicot/etc/httpd/php_mods”

mkdir /home/racicot/etc/httpd/php_mods

Added the following to the .htaccess

AddType application/x-httpd-php-cgi .php .phtml
Action application/x-httpd-php-cgi /cgi-bin/php.cgi

10) MAPSERVER

Had to change the following to get php_mapscript to statically get the library
path for gdal. This is done in the makefile in the php directory:

RUNPATHS= -Wl,-rpath,/home/racicot/gis/proj4/proj-4.4.9/src/.libs -Wl,-rpath,/home/racicot/gis/mapserver/mapserver-4.8.3

To:

RUNPATHS= -Wl,-rpath,/home/racicot/usr/local/lib -Wl,-rpath,/home/racicot/usr/local/src/proj4/proj-4.4.9/src/.libs -Wl,-rpath,/home/racicot/usr/local/src/mapserver/mapserver-4.8.3

Now configure and build…

./configure --with-jpeg --with-gd --with-freetype --with-zlib --with-png --with-pdf=/home/racicot/usr/local --without-tiff --with-proj=/home/racicot/usr/local --with-threads --with-ogr=/home/racicot/usr/local/bin --with-gdal=/home/racicot/usr/local/bin/gdal-config --enable-debug --with-php=/home/racicot/usr/local/src/php/php-4.4.2 --enable-runpath

make cp legend mapserv scalebar /var/www/cgi-bin/ cp mapscript/php3/php_mapscript.so /etc/httpd/php_mods/

11) libtiff

wget ftp://ftp.remotesensing.org/pub/libtiff/tiff-3.8.2.tar.gz tar -xzvf tiff-3.8.2.tar.gz ./configure --prefix=home/racicot/usr/local make make install

12) TCL/TK
wget http://superb-west.dl.sourceforge.net/sourceforge/tcl/tcl8.4.13-src.tar.gz wget http://superb-west.dl.sourceforge.net/sourceforge/tcl/tk8.4.13-src.tar.gz

cd ~/usr/local/src/tcltk/tcl8.4.13/unix ./configure --prefix=/home/racicot/usr/local make make install

cd ~/usr/local/src/tcltk/tk8.4.13/unix ./configure --prefix=/home/racicot/usr/local --with-tcl=/home/racicot/usr/local/src/tcltk/tcl8.4.13/unix make make install

13) FFTW

wget http://www.fftw.org/fftw-3.1.1.tar.gz

cd fftw-3.1.1 ./configure --prefix=/home/racicot/usr/local make make install

14) GRASS

./configure --prefix=/home/racicot/usr/local --with-gdal=/home/racicot/usr/local/bin/gdal-config --with-postgres-includes=/home/racicot/usr/local/include --with-postgres-libs=/home/racicot/usr/local/lib --with-includes=/home/racicot/usr/local/include --with-libs=/home/racicot/usr/local/lib --with-proj-share=/home/racicot/usr/local/share/proj --without-opengl

I then made a change to the makefile to statically add the lib path
so I would not have to update LD_LIBRARY_PATH

emacs include/Make/Platform.make

Added “-Wl,-rpath,/home/racicot/usr/local/lib” to both the CC and LD SEARCH_FLAGS

CC_SEARCH_FLAGS = -Wl,-rpath-link,${LIB_RUNTIME_DIR} -Wl,-rpath,/home/racicot/usr/local/lib
LD_SEARCH_FLAGS = -Wl,-rpath-link,${LIB_RUNTIME_DIR} -Wl,-rpath,/home/racicot/usr/local/lib

make make install

15) GMT

Make a GMTParams.txt file
run install_gmt shell script

Needed to re-run:
make install install-suppl clean make install-data make install-man make install-www

Make sure to point all of the GMT directories in the param file to the local user area…

Well… that is it. Mapserver, GMT, and command line GRASS all installed and working!

An alternative if you don’t need all these components or are not keen on compiling all of them you can install the linux version of FWTools. Works for me on dreamhost as a simple raster WMS server.
FWTools contains:
MapServer
GDAL/OGR
PROJ.4
and a couple of other components.

Andrew,
Thanks for the reply, and yes you are right FWTools is a great package. A few things of note:

1) If you are planning to use MapScript of any flavor (other than Python) you will not get those with FWTools.
2) If you need to build against anything later (i.e. development versions) than what Frank puts out you will not be able to use FWTools.

In general it is a great option for 99% of the people and I am glad that you pointed it out! I just installed it my self for serving WMS as well
