Re: Alien::wxWidgets questions

Hi,
Took a look at Wx::Scintilla - great work. With a minor build tweak (on my build systems some stuff isn't in the assumed locations - I'll post a patch) builds and works on Windows for me with a number of Perls. 

For info, Wx already has a build system for Wx extensions - but using EUMM.


As an example, the attacked Makefile builds Wx::Scintilla if the 
scintilla wxWidgets dll is already built.



The only hard coded part is the LIBS line which I was too lazy to set up 
properly.



Obviously, it is of no use to your build system - but the point is, you 
don't have to figure out the correct compiler and linker lines, the 
Wx::build modules do that for you.


I guess you could use and adapt Wx::build code for a Module::Build install.

Building the scintilla wxWidgets dll is a bit more problematic.


However, I'm pretty sure that the methods provided by Alien::wxWidgets 
give you more or less everything you need to create the necessary 
compiler and linker lines without having to work it all out yourself.



I'll see if I can do the necessary in your Module::Build bits to get 
build working across Windows/Linux/Mac using just the info from 
Wx::build and Alien::wxWidgets.



I'll certainly upload and maintain PPMs for Wx::Scintilla and I'll try 
to better keep up with PPMs for Padre releases. For Padre, I need to 
'diary on' say 7 days from a Padre CPAN release until the engines of 
ActiveState have caught up with PPM builds for latest non-wx dependencies.


Hopefully have some build patches soon.

Regards

Mark

Hi,

Thanks for the quick reply :)



I use mingw-w64 32 and 64 bit gcc compilers to build against all current
versions of ActivePerl. A recent gcc from mingw.org works too.



I was referring the broken ActivePerl PPM gcc + dmake support. The one
you get when you run cpan Alien::wxWidgets (after a fresh ActivePerl
installation) and it tells you that it cannot find a working compiler
and it downloads the one from ActiveState PPM repository. I will post
the exact log if you are interested. VC++ CL is not registered in PATH
unless you explicity call "%VS_STUDIO_HOME%\VC\bin\vcvars32.bat"
first.


Occasionally, in the past, a particular release of ActivePerl broke gcc
compatibility, though I can't remember the last one. (one of the 5.10.1
releases)

For this reason I'm in the habit of still using ExtUtils::FakeConfig,
creating my own libperl5xx.a and loading a Config_w64.pm
( http://www.wxperl.co.uk/building/Config_w64.pm )


- What are the supported Alien::wxWidgets configurations of over
Linux, Mac OS X and other platforms?


Not sure what you mean?



Alien::wxWidgets compiler / platforms tested support matrix. For example:
On Linux, Alien::wxWidgets links to libs or from source. Supports only gcc?
On win32, gcc or VC++ cl (ActivePerl). Only gcc on strawberry and Cygwin.
On Mac, only gcc also?


- How can one could 'require Alien::wxWidgets;' and then call
Alien::wxWidgets->compiler without a 'use Alien::wxWidgets' it?

Please note that I am asking about the supported configurations to
develop a proper Wx::Scintilla test plan. Hopefully, I will get more
tester reports for Wx::Scintilla on different platforms.

P.S. I need PAUSE *co-maintainer permission* on Wx::Event so I can
extend it without the PAUSE indexer complaints.


you can also defeat indexer by splitting the package line

package

  Wx::Event;



Fixed in 0.09. Thanks for the tip :)


alternatively, you can add your events in your XS code - which may be the
preferred way for new stuff. See Wx source
ext/richtext/RichText.xs



Thanks, I will take a look at it.


Hope it helps.

It helped a lot.

Thanks, :)
