need help with generating python bindings

[Suman Chatterjee]

Hi Phil,
I have a question. I see all the sip files from PyQt are generated with the help of a  software called MetaSIP. Is there a way that we can access this software. We actually develop on top of Qt and we have lot of libraries and all the classes derived from QObject. Wondering if there is a simpler way to create the python bindings rather than having to create one .sip file corresponding to each header file.
Let me know what will be the best way to do it.
Thank You,
Suman

It worked!!  I was missing a ReadMe file. When I created a ReadMe file it worked.

Thank You so much Phill for your help!! I will try now with some other C++ libraries.

Thank You so much Phil!! I appreciate your fast response.

But I tried that already. It returns me the below error. It is able to make the build but fails during install.
Is there anything I am missing.


sumxxx:bin sumxxx$ source activate pythonBindingsEnv


(pythonBindingsEnv) sumxxx:pythonBindingsEnv sumxxx$ cd sip

(pythonBindingsEnv) sumxxx:sip sumxxx$ sip-install

Querying qmake about your Qt installation...

These bindings will be built: QtChart.

Generating the QtChart bindings...

Generating the .pro file for the QtChart module...

Generating the top-level .pro file...

Generating the Makefiles...

Compiling the project...

Installing the project...

sip-install: 'make install' failed returning 2


Thank You,
Suman

Activate the environment, then install sip, PyQt-builder etc in the
environment. There is no need to specify any additional flags.
