Well, after a bit of trial and error I understand the bit about building
a signed interpreter (Actually, this is working as I want it to work).
Currently I use my default installation that has QT and PyQT installed.
With this setup anyone would be able to use the existing libraries with
a generic python interpreter and bypass our signed interpreter. Not good.
What I think about doing is:
- Compile the pyQT modules statically into python
- Generate a singed interpreter for our applicaton
- Distribute the signed interpreter + any additional scripts + the
python libs (including pyQT)
But here are the questions:
How about QT?
Imho I do need a QT library before I can build pyQT. Then, is it
necessary to patch the code of QT to make it VendorId-aware? If so,
where? Or how should I deploy the QT libs?
How about PyQT?
Is it enough if I configure PyQT with the -i command line switch to
make it vendorId aware?
Once again our objective is not to make a self-contained .exe but rather
a solution, that leaves some of our code exposed to modifcations ....
Thanks for the help so far...
