building from source

[Moorea]

Thanks, as revision 13 it all builds out of the box !
(the first launch it had a strange black bar + 2 buttons; one of them called "add a toon" but nothing happened when clicking it) - after clicking "computers" it went away permanently)

Yay.

The bar is something I had just begun to work on when I posted that build. I tried to disable it in build 13 so people wouldn't worry about it, but your comment makes me realize that people may see it once when the program starts up depending on settings left over from the previous build.

In the next build the bar will look like it's attached to the thing it affects and hopefully it won't look strange.

Another question: I'm now using visual studio 2010 ultimate beta 2 and it still complains that it can't open MojoInstaller part of the project - any idea what extension or component I would need to get for that one ? (not that I really care about building the installer but to avoid the error message at startup and for completeness sake)

(I didn't see that on the otherwise very nice
http://mojoware.org/p/overview-for-programmers.html
unless "clickonce" is the stuff I need to get ?)

[Freddie]

Yeah it would be nice if people can just download the whole thing and build it without any problems.

I don't know what could be missing. The installer (unlike everything else) is a .NET program and I know practically nothing about .NET.

I'm trying to remember what I did when I installed VS 2010 and wrote the installer. I think I just went with the defaults. Did you include the C# / .NET stuff when you installed it?

Thanks. I think everything ClickOnce needs comes automatically with .NET but maybe I'm wrong, I know next to nothing about .NET.

hmmm it's possible I only put C++ - I'll rerun setup - thanks

I don't know, but there's a copyright issue. I'm planning to retain the full copyright to the version of Mojo in the mojoware repository. If people send code to me, even if it's just for consideration, that may raise legal issues. I don't know any IP lawyers who I can consult for free about this so I'd just rather not go near it for the time being.

Uhm....am I missing something? You have the GNU GPL license published with the source so I assume the code is made available with a GNU GPL license which in turn means anyone can modify and distribute the code.

Copyright as far as the GNU GPL is concerned is to ensure you get credit for what you write and that someone doesn't take your code, claim they wrote it and then take ownership of the code. From the GNU GPL FAQ:

Why should I use the GNU GPL rather than other free software licenses?
Using the GNU GPL will require that all the released improved versions be free software. This means you can avoid the risk of having to compete with a proprietary modified version of your own work.

And with "free software" they don't mean you can't sell it, just that if you sell it / distribute it then you need to make the source code available as well and whoever you sell / distribute it to has the right to sell / distribute it as well without any obligation to you.

Some other useful stuff:

Why does the GPL permit users to publish their modified versions?
A crucial aspect of free software is that users are free to cooperate. It is absolutely essential to permit users who wish to help each other to share their bug fixes and improvements with other users.
Some have proposed alternatives to the GPL that require modified versions to go through the original author. As long as the original author keeps up with the need for maintenance, this may work well in practice, but if the author stops (more or less) to do something else or does not attend to all the users' needs, this scheme falls down. Aside from the practical problems, this scheme does not allow users to help each other.
Sometimes control over modified versions is proposed as a means of preventing confusion between various versions made by users. In our experience, this confusion is not a major problem. Many versions of Emacs have been made outside the GNU Project, but users can tell them apart. The GPL requires the maker of a version to place his or her name on it, to distinguish it from other versions and to protect the reputations of other maintainers.

And:

Does the GPL require that source code of modified versions be posted to the public?
The GPL does not require you to release your modified version, or any part of it. You are free to make modifications and use them privately, without ever releasing them. This applies to organizations (including companies), too; an organization can make a modified version and use it internally without ever releasing it outside the organization.
But if you release the modified version to the public in some way, the GPL requires you to make the modified source code available to the program's users, under the GPL.
Thus, the GPL gives permission to release the modified program in certain ways, and not in other ways; but the decision of whether to release it is up to you.

The full FAQ is here.

In other words, anyone can take an exact copy of the source and start a new GNU GPL project with your source and develop their own version in parallel with yours.

Yes, multilicensing. I don't know if I'll do it, but I'm going to preserve the option.

Interesting. So basically keeping the option open of a premium service at a price and an Open Source project limited in some way. Which means you cannot use any contributions / modifications made under the GPL license. Ok, got it.

hmmm it's possible I only put C++ - I'll rerun setup - thanks

that was it indeed - added C# and now it's happy


ps: I guessed as much about mutli licensing / keeping your options open for later and that's sounds fine / fair

[Freddie]

Good.

I'll add a note to the readme about that.

Edit:

Thanks a lot for helping me fix this. Getting it to build on any machine that downloads it, is important.
