#28 No success on freezing with nuitka (and how to freeze ?)

[alfazaz]

Hello !

I try to freeze my app which uses pygi on windows with nuitka and it doesn't work (no problem on linux). You can look at this on http://bugs.nuitka.net/issue242. I write this message because I don't know where is the problem (dependency walker on a really simple test case is on the latest link).

Is there a bug in pygi ? Is it my mistake ? (Optional question : how can I freeze an app that uses pygi on windows ? I didn't succeed with cx_freeze, pyinstaller... :-( ). I use python3.4 32bit.

Thanks in advance !

Sorry, Have you tried rev22 (the switch to os.environ instead of putenv) may help packaging.

[tumagonx]

BTW when thing like "import error" happen during packaging, the first thing you should try is adding gnome subdirectory into PATH environment

[tumagonx]

Since we are talk about broad possibility of packaging it would better to put this at discussion, so other guys with different bundler may share their experience.

Ok. I will try your suggestions in the next minutes. About discussion on freezing, I posted a message on monday in the discussion section but it is still on moderation stage (awaiting moderation) ; see https://sourceforge.net/p/pygobjectwin32/discussion/general/thread/b8d6781c/ ;-)

I installed rev22. Programs work with python interpreter, but no success after freezing. It fails like on the example I put on http://bugs.nuitka.net/issue242.

Here is my PATH :

Here are all messages :

---

During handling of the above exception, another exception occurred:

So now, I don't know what to try...

[tumagonx]

Thanks, I will try nuitka myself and maybe cx_freeze (I think lazka of Quodlibet succesfully use it)

[alfazaz]

Ok. If you have success with it, thanks in advance to share your solution ;-).

(nothing to do here but sourceforge is strange for me : it marked 2 messages from me with "Post awaiting moderation" and they are still in this state... I can't even see the writings in these messages... ???? + I don't receive know notifications for new messages... Mysteries, mysteries...).

I could get past typelib stuff, You need to copy gnome folder's content into yourapp.dist folder
But I get segfault... GDB show :

Oh if I don't use --portable it run well. hmm

[tumagonx]

Uugh it's hard debug...
Well basically all you need is to copy gnome's content alongside the produced exe (assuming wtihout --portable option)

[alfazaz]

Gloups, it's the same for me without --portable option... But I need this option because I want to run my program on windows targets without all python stuff :-(. That's why I need to freeze my app.

[tumagonx]

I'm closing this as it's irrelevant to pygi or rather it's like "does niutka has specific pygi support like pyqt?" not yet.
So it is niutka's problem not pygi. As a matter of fact run via interpreter mode is OK.

I updated my answer here https://sourceforge.net/p/pygobjectwin32/discussion/general/thread/b8d6781c/ You might want to link that page to your niutka bugreport.

Regarding the segfault, it because niutka's default -O3 optimization level seems make my gcc produce unstable binary, lowering it (-O2/-Os/-O1) will make it works.

[alfazaz]

I linked your pages on nuitka bugreport. Thanks !!
