Static linking of python and pyqt

[Markus Dahlbokum]

Hello,

I'm trying to link python statically with qt and pyqt. I've tried this in
several ways but never succeeded. At the moment the final make runs without
errors but I get import errors when accessing pyqt.
How can I solve this problem?

I'm trying to link python statically with qt and pyqt. I've tried this in

How can I solve this problem?

You'll need to include QtCore into Modules/config.c, preferably by
adding it to Modules/Setup.local.

I tried this in combination with the QtCore libs from pyqt. But there seems to
be a conflict between the pyqt package and the linked libs. Therefore I tried
to link only qt statically and import pyqt dynamically. But in the
Setup.local you need to specify a module:

<module> <lib>

I just want the qt libs linked to the interpreter without accessing them by a
module. I tried the configure option '--with-libs='lib ...''. The make did
fine but the executable is too small and the qt symbols are not known by it.
How can I just link qt statically?

Thank you.

Why do you want to do this? If qt isn't actually *used* in Python (as
you don't include the pyqt modules), what effect do you expect from
such linking?

I think it linked just fine - it just didn't include any symbols,
because none were needed. That is the correct, expected behavior.
It all worked fine.

Martin

I need an environment that can be delivered to our customers without
installing python, qt and pyqt. We want to provide the complete package.
In order to do so I need to link at least python and qt. How can this be done?

Of course a complete package with python, qt and pyqt would be the best
solution but there seem to be even more complications that way. If you can
help me with this I would be very grateful.

Thank you in advance.

I don't think you will succeed in that attempt. Statically linking means
statically refering, as martin says. I'm not an expert, but as qt refers to
PyQt (via sip-bindings) but the latter one isn't explicitly refered to by
the python-interpreter itself, you won't get the linking right.

I've got the agfeo Tk-suite client running on my system - it's a windows +
linux qt-based app. And it ships completely with a version of qt, locally
installed into it's program-dir. An approach that is even more common in
OSX and Windows. So you might consider using that instead.

You should link all extension modules into the Python executable,
through Setup.local

Not sure. You didn't explain what the precise problem is, so it's
difficult to help in correcting it.

If it's for windows, py2exe works like a charm for this kind of setup.

For windows + linux, you might one to try one of:
