wxruby users - Aug 2006 - building wxruby2 from cvs (gentoo)

Hello,

I am a newbie to wx and wxruby, I just built wxruby2 on my gentoo box.
At first it did not work. So I post a little message,it might help others.

At first a cryptic message was shown

SWIG Version 1.3.21
Copyright (c) 1995-1998
University of Utah and the Regents of the University of California
Copyright (c) 1998-2003

Compiled with i686-pc-linux-gnu-g++ [i686-pc-linux-gnu]

Please see http://www.swig.org for reporting bugs and further information
Doing slower check for SWIG 1.3.29
rake aborted!
Don''t know how to build task ''src/App.cpp''

(See full trace by running task with --trace)

-
It turns out the by default swig on gentoo is not compiled with ruby support
and the default version is older then the recommended one

so I installed a new swig version with ruby support
#edited
/etc/portage/package.keyword
#and added
dev-lang/swig
#edit
/etc/portage/package.use
#added
dev-lang/swig ruby


The second point where it failed was here
src/App.cpp:1622:21: wx/init.h: No such file or directory
src/App.cpp: In member function `bool wxRubyApp::Initialize(int&,
wxChar**)'':

e()
rake aborted!
Command failed with status (1): [c++  -c -I/usr/lib/wx/include/gtk2-2.4 -DG...]

(See full trace by running task with --trace)


my gentoo has two versions of wx installed
(2.4.2 and 2.6.2) (2.4 is the default), so the wx-config points to the
2.4 configuration while the wx-config-2.6 to the new version.
I changed wx-config for wx-config-2.6 in rake/rakewx.rb at line 41
perhaps the developers can add a check to see if wx-config-2.6 is in the path?

anyway now it all works  and I can start playing around

Thanks

Hello, welcome, and thanks for contributing!

Yes, we have a bug in our tracker noting that older versions of SWIG are
not properly detected. This could be fixed by someone who knows nothing
about C++, SWIG, or even wxRuby. It would be great if someone could
volunteer to take care of it.

Interesting. I just added a bug to the tracker requesting a wx version
check in the rakefile. For Linux, it''s very easy. I seem to recall that
MSWin doesn''t have wx-config available, so I''m not sure how
the version
would be detectable on that platform.

Excellent. Please report your findings, good or bad.

Thanks,

I am playing with the maemo platform. This was the first run on the sdk.
You might not enjoy it as much as I did but here is it

I just can''t wait untill I can develop my gui''s in ruby on
this little toy

I had not heard of maemo. I assume you mean this:

http://www.maemo.org/about.html

So you hope to be able to write apps in wxRuby that will run on this
mobile Nokia tablet device? Interesting.

Yes, it is the platform that runs on the Nokia 770

Yes, I even hope to write apps "on" that same Nokia(using a real
keyboard of course)

Today I actually managed to get wxruby running on the real device.
I did not want to install rake/gem on the device since it might become to much
So I tried creating a debian package for wxruby (failed because i
don''t know how I am supposed to install a ruby package without rake).
I ended up just copying wx.rb and wxruby2.so to the device and it
worked. I must note that before I was able to do this I had to run
strip on the
wxruby2.so (it was 41MB !!!) and back to a few MB after the strip.

The startup time of the textctrl app was really slow about 10 seconds
or so.One running the performace seamed ok. I don''t know what the
slowest component it

It might be interresting to start ruby , load the libs and try to run
multiple apps in the interpreter. it that possible? That would greatly
reduce startup time.

The bigest problem right now is that wx ins''t ported to the maemo
platform. It runs the gtk code , but I there are issues :)

The other problem Is that I have 2 week holidays starting tomorrow :)

Thanks for the interest
