Hi!
Thanks all for the answers. I have in fact an issue between Perl and
Proj4 that I can't understand. I normally compile Proj4 from source
without problems. The install tree is /usr/local, with executables in
/usr/local/bin, libraries in /usr/local/lib and headers in
/usr/local/include. I use this package as part of a larger set of GIS
related programs and I do not experience problems: packages like GDAL,
GRASS and QGIS find Proj4 without pain. At the moment I am using the
latest source: 4.6.1.
Now, when installing Geo::Proj4, for example, warning messages appear
saying that -lproj cannot be found. The problem is that Geo::Proj4
looks for FWTools by default, so Makefile.PL has to be modified
accordingly, i.e. deleting calls to FWTools and pointing to where
Proj4 is (because I want Proj4 to be used, not FWTools).
With PDL this does not work. Using the default perldl.conf file I get:
Will forcibly try and build PDL::GIS::Proj on this system
PDL::GIS::Proj: Found /usr/local/lib/libproj.so
Trying check for projUV...
YES
Building PDL::GIS::Proj. Turn off WITH_PROJ if there are any problems
Note (probably harmless): No library found for -lproj
Writing Makefile for PDL::GIS::Proj
Writing Makefile for PDL::Lib::GIS
Writing Makefile for PDL::Transform::Cartography
Will forcibly try and build PDL::Transform::Proj4 on this system
PDL::Transform::Proj4: Found /usr/local/lib/libproj.so
Building PDL::Transform::Proj4. Turn off WITH_PROJ if there are any problems
Note (probably harmless): No library found for -lproj
Writing Makefile for PDL::Transform::Proj4
Writing Makefile for PDL::Transform
And, if I modify the perldl.conf file to point to the libraries and
includes, I get
Will forcibly try and build PDL::GIS::Proj on this system
Trying check for projUV...
YES
Building PDL::GIS::Proj. Turn off WITH_PROJ if there are any problems

... that is, not even finding anything!
I am not sure about the origin of this problem.
