= Perl =

Perl is the base of all higher level tools in Geoinformatica. The following assumes Perl 5.10.0

The makefile.mk in win32/ is the build configuration. I'm adding -mms-bitfields to line 525. see 
[http://markmail.org/message/6zlo6cktiqa72eht this discussion]

Also, I change INST_TOP to $(INST_DRV)\Geoinformatica

The build is easy, in dos command prompt:
{{{
dmake
dmake install
}}}
Perl modules are always built in shell using dmake

lib/ExtUtils/Liblist/Kid.pm needs to be patched with [wiki:KidPmDiff Kid.pm.diff] (works for EU::MM 6.52) to make it find import libraries that end with .dll.a

= GTK+ =

GTK+

I'm not building these myself. We'll need both

ftp://ftp.gtk.org/pub/gtk/v2.10/win32/ and

http://gladewin32.sourceforge.net

since we need Gtk2::!GladeWin 

= Glib, Cairo, Pango, and Gtk2 modules =

ExtUtils::Depends is one of the prerequisites of these. Currently it needs to be patched with a patch attached to 
[https://rt.cpan.org/Ticket/Display.html?id=45224 this bug report]

Also pango.exports needs (1.220) 
{{{
gtk2perl_pango_attribute_register_custom_type
gtk2perl_pango_attribute_get_type
gtk2perl_pango_attr_iterator_get_type
gtk2perl_pango_script_iter_get_type
}}}

and newSVPangoRectangle and !SvPangoRectangle need to be removed from Gtk2.exports (1.220).

= Data access and geo libraries =

These are built in MSYS. Most are used by GDAL.

* pq to access data in PostgreSQL and PostGIS
  * it's possible to use the libpq from the Windows ports of these 
* expat, needed for curl
  * there's a good Windows port with devel support available in it's home page 
* curl, needed for WMS, WCS, WFS
* GEOS for simple features methods
* Proj4 for cartographic projections
  * the DLL needs to be made manually: 

{{{
cd src
gcc -shared -o libproj.dll -Wl,--out-implib=libproj.dll.a \
-Wl,--export-all-symbols -Wl,--enable-auto-import -Wl,--whole-archive \
.libs/libproj.a -Wl,--no-whole-archive /c/mingw/lib/libmingw32.a
}}}
