GDAL 1.5.0 Perl Binding on Cygwin

[Jingmu Yang]

I have successfully built GDAL 1.5.0 Perl binding on Cygwin and the followings might be helpful for those who experience problems.

1. Go to directory gdal-1.5.0/swig/perl and run 'perl Makefile.PL'.  The following four Makefiles should be created if it succeeds:

Makefile_Geo__GDAL
Makefile_Geo__GDAL__Const
Makefile_Geo__OGR
Makefile_Geo__OSR

2. Edit each of the four Makefiles by appending -lstdc++ after each -lgdal and save them.

3. Run make using each of the four Makefiles as follows:

make -f Makefile_Geo__GDAL
make -f Makefile_Geo__GDAL__Const
make -f Makefile_Geo__OGR
make -f Makefile_Geo__OSR

4. Install the Perl Geo::GDAL package by running

make -f Makefile_Geo__GDAL install

That it.  Enjoy!

Jim

If you tell me how to detect Cygwin reliably I can add this to Makefile.PL

"make build" does this, sorry, I know its non-standard outside of gdal,
where it is standard :)

"make install" should do this

Ari,
Within GMT a cygwin installation is detected with a

#ifdef _WIN32

and that has worked well since a long time.

Ah, I meant in Makefile.PL, i.e., by Perl. It's probably something in
Config.pm?

I believe that using `uname | grep CYGWIN` in Makefile.PL should be able to handle the Cygwin system type.

Cheers,

I fixed this problem by editing a Cygwin script /usr/bin/perlld from:

my $CC = 'gcc';
to:
my $CC = 'g++';

This seems to fix other perl problems (non-GDAL) with Cygwin as well.
When I pointed this out, the Cygwin folks thought it was a bug but
wanted to investigate why this was set to gcc in the first place.

Anyway, my problem remains with perl swig bindings on Cygwin. I know Ari
wants nothing more to do with this issue, but since we're on the
subject, maybe someone else might able to give me a clue.

It seems I have a problem linking with the gdal lib with external libs.
  I get a ton of these types of messages below - I think the issue has
to do with the beginning underscore in the calls because rikdataset.cpp
calls "uncompress" not "_uncompress":

/usr/local/lib/libgdal.a(rikdataset.o):rikdataset.cpp:(.text+0x519):
undefined reference to `_uncompress'
/usr/local/lib/libgdal.a(jpeg2000dataset.o): In function
`_ZN18JPEG2000RasterBandC2EP15JPEG2000Datasetiii':
/home/pmallas/gdal/frmts/jpeg2000/jpeg2000dataset.cpp:257: undefined
reference to `_jas_matrix_create'
....

I am ignorant of how libraries get called - probably the windows demands
a prepended underscore for library calls or something. And I know there
are flags to manipulate leading underscores with g++ (like
-fleading-underscore), but I could never get them to work. I have spent
considerable time trying to sort this out with no luck.

Any insights would be appreciated.

I experienced the same problem when I initially built GDAL 1.5.0 on
Cygwin.  After analyzing the libraries I found that I had old GDAL
libraries installed on /usr/local/lib/.  What I did was to delete those
old libraries from /usr/local/lib and then built GDAL 1.5.0 without Perl
binding.  After GDAL 1.5.0 was installed on /usr/local/ I built Perl
binding as I described and I no longer have the link problems.

Hope this can help.

I finally got the GDAL Perl bindings to compile on Cygwin.

In addition to the c++ library issue that Jim mentioned, I used the
--without-libtool option in the configure script when building the gdal
library.
