Hi Mark, Sorry for the delay, my laptop died and I got on with other stuff while I bought another one.
Anyhow, back to the Wx::MediaCtrl install. I managed to install 11.4 plus wxWidgets 2.8.12 successfully and the wxMediaCtrl works on wxWidgets. I also installed Wx and Wx::Demo from cpan. Wx::MediaCtrl does not work, bit Wx::Demo no longer crashes (I recall you, Mark, fixed this). The errors during the install from the default cpan libraries are: make[2]: Entering directory `home/image/.cpan/build/Wx-0.9901-reNeqB/ext/media' make[2]: Nothing to be done for `all' make[2]: Leaving directory `home/image/.cpan/build/Wx-0.9901-reNeqB/ext/media' So something is missing at this stage. I'm not sure what should be happening, but clearly there it's an error because all the dependencies are fulfilled (ie the video works on plain wxWidgets sample/mediaplayer). Where should I look for what should be done and why is the Makefile not giving anything to do for `all'? As is probably evident, I'm not really familiar with the functions being used here (make etc). If you could point me to some doc that would be great.

I'll answer more fully when I've processed your different options and got some test results. Maybe I should start off with a clean build. Thanks for this. In fact, the wxWidgets doesn't give me any problems at all. I've built 2.9.2 and 2.8.12 just using ../configure .......... My video works fine under wxWidgets 2.9.2 and Kubuntu 11.4. Your .pl video sample works beautifully under 10.4 LTS (I sent you most of the script that I use. It works on 10.4, but I don't have a clean build yet with 11.4. Which version are you using? Did you get a chance to test it?). Anyhow it's wxPerl with video that killing me on 11.4. Anyhow, I need to go and run some errands now, but I'll get back on the case later today and I'll send you a fuller response. What time-zone are you based in?

Eventually, of course, the SVN code gets released to CPAN but for now with 2.9.2 you'll need SVN. You may also need to decide if you want version 2.8 compatibility - and to be honest I have no clue what that would mean in practical terms, not using 2.9.2 myself. Your build command would look something like the following perl Build.PL --wxWidgets-extraflags="--enable-graphics_ctx --enable-mediactrl" --wxWidgets-build='yes' --wxWidgets-source='tar.bz2' --wxWidgets-unicode=1 --wxWidgets-build-opengl=1 --wxWidgets-version=2.9.2 Note that 2.9.2 doesn't have tar.gz source available - you need the bzip2 tarball. There is no need to use builtins for the libraries. I often use them because I'm often building a binary for re-distribution - but I can't see it making sense in your case. However, having said the above given that you have a current focus on fixing issues with wxMediaCtrl, if I were you then I would build wxWidgets myself outside Alien-wxWidgets as a first step. This way, you get to see the output of your options to ./Configure and can more easily identify where Configure is not finding the necessary development libraries to build the options you want - rather than building the whole thing and then only finding that what you want is missing when building wxPerl. You also get the advantage of more easily building the c++ wxWidgets samples. As an example, you could build 2.9.2 with an install prefix of /var/local/wxtesting-2.9.2/widgets and 2.8.12 /var/local/wxtesting-2.8.12/widgets when building Alien::wxWidgets + Wx ..alien export LD_LIBRARY_PATH=/var/local/wxtesting-2.9.2/widgets/lib export PERL5LIB=/var/local/wxtesting-2.9.2/perl/lib perl Build.PL --prefix=/var/local/wxtesting-2.9.2/perl perl Build test perl Build install ..wx perl Makefile.PL PREFIX=/var/local/wxtesting-2.9.2/perl make make test make install And the same but replacing 2.9.2 with 2.8.12 for your 'stable' widgets build ..alien export LD_LIBRARY_PATH=/var/local/wxtesting-2.8.12/widgets/lib export PERL5LIB=/var/local/wxtesting-2.8.12/perl/lib perl Build.PL --prefix=/var/local/wxtesting-2.8.12/perl perl Build test perl Build install ..wx perl Makefile.PL PREFIX=/var/local/wxtesting-2.8.12/perl make make test make install Having done that, you can rebuild bits of it all without necessarily having to keep rebuilding the whole. You can just switch your PERL5LIB export PERL5LIB=/var/local/wxtesting-2.9.2/perl/lib export PERL5LIB=/var/local/wxtesting-2.8.12/perl/lib to change the current Wx you are using. My thought is, that for both 2.9.2 and 2.8.12 branches, you can check if the C++ GStreamer sample works. Once you have a working C++ sample , you can look at what, if anything, is getting in the way of the wxPerl wrapper working. It is a big 'ask' if all you want is a working wxMediaCtrl, but I think if you are willing to take it on you need to become familiar with the wxWidgets build and Configure scripts. Then you will be able to build the base wxWidgets configured how you want it. I see 3 main groups of issues: 1) Getting correct dependencies so you can build a functioning wxMediaCtrl 2) Getting Wx::MediaCtrl to display anything on many Linux distros. ( I haven't managed to do this at all in my dabbling) 3) Enhancing wxMediaCtrl to handle streams on all platforms and fixing any current 'showstopper' bugs. As I understand it, you would really like to tackle 3) and to do that I think you would need to be comfortable in building and using wxWidgets as a C++ toolkit without any 'Perl' involvement. 2) is currently really irritating me. I'm sure there's something simple I'm missing. I've never been able to use wxMediaCtrl on Linux - ever - so it must be my code / setup as the thing clearly works for some people some of the time. Well, - I hope some of it helps. Regards Mark On 07/07/2011 12:27, Steve Cookson wrote: > Hi Mark, > > I don't know why this hasn't surfaced before.
