abchr-users — General discussion about compiling and using ABC/HR

[Abchr-users] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

You are the only one I've heard of, but then again, you're possibly the
only one brave enough to try compiling abchr on Max OS X :)

Could you make a debug build of abchr? On other platforms this would
entail passing the -g flag to gcc, but I don't know if that is true on
Mac OS X. If possible, could you also make a debug build of wxWindows?
With the debugging information, the back trace will show more helpful
information that might help me track down the problem.

When you send me the enhanced back trace, please let me know the full
version number of wxWindows you're using, so that I can cross-reference
the back trace with the correct source code.

Thanks,

Carsten.

Hi,

It now compiles fine on Mac OS X :)

However, it segfaults immediately when run. I haven't tried debugging  
C++ code before, so I'm not quite sure how I should find the exact  
location of the bug. The stack trace - pasted below - suggests that the  
bug is in wxWindows (I'm using 2.4 for mac) since it never makes it  
into main(), but dies loading wxWindows. Am I the only one experiencing  
this?

Here the is the back trace:

[Abchr-users] Experimental PortAudio Support

[Carsten H. <ca...@un...>]

Hiya,

I have uploaded a forked version of 0.2 that uses portaudio
(www.portaudio.com) instead of SDL for audio output. Please give this
one a try if the SDL version causes problems, and let me know if it
works better (or at all :)

Please refer to
http://sourceforge.net/project/showfiles.php?group_id=91836&release_id=189741 for release notes and to download the package.

Cheers,

Carsten.
