How to install QWT

[ppham1504]

Hello all,

I am currently having trouble installing the QWT package on my Windows 7 PC. Precisely, I have no idea how to install it. The link to this package is http://qwt.sourceforge.net/ . I've also looked at their installation instructions at http://qwt.sourceforge.net/qwtinstall.html but still have no luck getting it to work. Can anyone help me?

Thanks,

[alainstgt]

which compiler and IDE do you intend to use?

Hello Alain,

I want to use the PyScripter and Python 2.7. I am attempting to recreate this project: http://danstrother.com/2011/01/15/reflow-oven-controller/ . The author has written a python GUI program to do this. However, this Python program requires the QWT package, if I don't have this package then when PyScripter tries to run the program, it'll give me the "ImportError: No module named Qwt5". I have spent the past couple hours to search for a solution but to no avail.

Regards,
Phuc

Qwt is a C++ library. You will also need the Python wrapper from http://pyqwt.sourceforge.net/

Here is what I have done so far
1. Download and install QT 5.0.1 (MinGw) to: "C:\Qt\Qt5.0.1"
2. Download and extract Qwt 6.1 RC3 to: "C:\qwt-6.1-rc3"
3. Add "C:\Qt\Qt5.0.1\5.0.1\mingw47_32\bin" to your systems path variable (qmake.exe is located here)
4. Add "C:\Qt\Qt5.0.1\Tools\MinGW\bin" to your systems path variable (mingw32-make.exe is located here)
5. Open a command line (cmd) and navigate to: "C:\qwt-6.1-rc3"
6. Type: "qmake" (This command won't prompt any msg so don't worry)

However, the next step is where I'm having trouble:
7. Type: "mingw32-make" => this is where I have been stuck for the past couple hours. I've included the output error from make here for you to see

Please take a look at it b/c I couldn't figure this out and google hasn't been able too either.

Thanks,

Remove the paths from the system PATH. Start a command prompt from the Start menu under Qt\5.0.1 (or 5.0.2 your post is confused). Run the qmake and build from there.

Hello Chris,

thanks for your suggestion. However, it didn't work. I've attached the errors report along with this post. Please take a look and tell me what you think. Btw, I installed QT 5.0.2, not 5.0.1. Sorry for the confusion.

The Qwt python bindings have never been ported to Qwt 6, so forget about Qt 5: your combination is Qt 4.8 + Qwt 5.2.

Hello uwe,

Thank you for your suggestion. I think I was able to install QWT and the PyQWT. However, I still got the same error below when trying to run the Python file. Can you help me out with this?
