Fix for building perl bindings was Re: [Gdal-dev] Newbie with OGR Perl bindings

[Kevin Ruland]

Matt,

There appears to be some problems with 'make install' in the perl
bindings - there are some work-arounds for it and if you use --prefix
things get a little harder.

If you decide to install gdal in either /usr/local or /usr/ (this is the
case when you don't use --prefix in ./configure),
the best option is to not use the --with-perl option, but instead do this:

./configure --normal-configure-options  (omit the --with-perl option)
make
make install
cd swig/perl
make
make install

This should install the perl module correctly.

If you desire to install gdal in a non-default location you will need to
hack the swig/perl/Makefile.PL script to get the build to function
correctly.

./configure --prefix=myprefix --normal-configure-options (omit the
--with-perl option)
make
make install
cd swig/perl
-- edit the Makefile.PL and change all the lines with LIB => "-lgdal" to
LIB => '-Lmyprefix/lib -lgdal'
make
make install

We are currently working on a platform independent way to make this more
automatic.  It should make it into cvs shorly, and in the 1.3.2
release.  Until then we'll have to struggle a little more.

Best of luck.

Kevin
