need help with generating python bindings

[Suman Chatterjee]

Thank You so much Phil!! I tried that example. Yes that error is gone and it is able to build the project using PyQt-builder
But the install failed with the below error.


sxxx:sip sumxxx$ sip-install --tracing

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


if I just use sip-build it builts the project

sxxx:sip sumxxx$ sip-build

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...

The project has been built.


But how do I install in a virtual Environment. If I specify target-Dir like this it throws the below error


(pythonBindingsEnv) sumanc2:sip sum10122$ sip-install --target-dir pythonBindingsEnv

Querying qmake about your Qt installation...

These bindings will be built: QtChart.

Generating the QtChart bindings...

sip-install: Unable to find file "QtGui/QtGuimod.sip"


So my question what is the way to install the generated python library in a virtual environment


Kindly let me know what to do.... I will really appreciate it.

Thank You,

Suman

If you are building bindings on top of PyQt then you need to use
PyQt-builder. This implements extensions to SIP.
