configure.in: wxwidgets and python checks

[martinl]

Hi,

I modified the configure script to support wxWidgets. It checks

• if wx-config is presented
• wxWidgets version (>=2.8.1 required)
• check for wx/wxprec.h and wx/wxPython/pseudodc.h (wxPython required too)

The patch also checks for Python.h header if --with-python is given.

This should solve compilation of wxGUI vdigit component

Add check for wxWidgets

From ML by Glynn Clements:

You should probably use python-config to get this information.

I would suggest that --with-wxwidgets and --with-python take optional arguments specifying the path to the wx-config and python-config utilities respectively, in case they aren't in the path. --with-gdal already behaves like this.

Also, is there any need to have vdigit/Makefile generated from Makefile.in. Can the configuration settings not go into Platform.make[.in]? vdigit/Makefile already includes Platform.make via Lib.make.

The patch checks for Python.h and include directory, it should work on Mac/Windows too.

The configure checks might work, but the hard-coded linking switches and ".so" won't work. I suggest trying to mimic a normal library build as closely as possible.

Based on Glynn's notes I updated the patch (see configure_wx-1.diff)

Instead of --with-python=path/py-config is used --with-python=path/python. Configure also checks for python-config.

  --with-python[=path/python] enable Python support (python with path, e.g. '--with-python=/usr/bin/python2.5', default: no)
  --with-wxwidgets[=path/wx-config] enable wxWidgets support (wx-config with path, e.g. '--with-wxwidgets=/usr/local/bin/wx-config', default: no)

requires python-config

Requires python-config, --with-python=[path/python-config]
