Build Python2.7 + PyQt4.11.3 + Eric4.0 development platform under CentOS 7

Install Python2.7
Python2.7 is installed in CentOS 7 by default. Therefore, the installation of Python2.7 can be omitted.

Install Qt4.8.7

Qt-everywhere-opensource-src-4.8.7.tar

# Tar-zxvf qt-everywhere-opensource-src-4.8.7.tar

# Cd qt-everywhere-opensource-src-4.8.7

#./Configure

# Make

# Make install

Connect qmake in/usr/bin to/opt/Qt/5.3/gcc/bin/qmake.

Ln-s/usr/local/Trolltech/Qt-4.8.7/bin/qmake/usr/bin/qmake

Install SIP
Version sip-4.16.7.tar

The official website said: "Before you can build PyQt4 you must have already built and installed SIP" means that you must install the SIP first, and then download the SIP.

Decompress the SIP package, go to the source code directory, open README, and say there is a build. py under the current directory. I cannot find the result. However, a configure. py code is found. So I executed it.

$ Python configure. py

Normally completed, and a Makefile is generated. I subconsciously execute make. Result:

Gcc-c-pipe-fPIC-O2-w-DNDEBUG-I.-I/usr/include/python2.6-o siplib. o siplib. c
Siplib. c: 20: 20: fatal error: Python. h: No such file or directory
# Include <Python. h>
^
Compilation terminated.
Make [1]: *** [siplib. o] Error 1
Make [1]: Leaving directory '/home/hevake_lcj/Install/qt-downloads/sip-4.15.3/siplib'
Make: *** [all] Error 2

Generally, this problem occurs when the system does not install components on the Development Board. Only the library files are provided, and the corresponding header files are not provided. Secondary Development is not allowed. The solution file is to install python-devel.

$ Sudo yum install python-devel

Complete the installation. Make again and compile it smoothly. Sudo make install again.

Install PyQt4
Version PyQt-x11-gpl-4.11.3.tar

Unzipping download: PyQt-x11-gpl-4.10.3.tar.gz

Go to the source code directory, open README, and follow the instructions to execute the configure. py script, and then make and make install.

Because I encountered an error when using eric4.

ImportError: No module named QtWebKit

The reason is that when compiling PyQt, QtWebKit is not installed, and that module is not compiled.
 
So before compilation, yum install qtwebkit

$ Python configure-ng.py
Querying qmake about your Qt installation...
Determining the details of your Qt installation...

Type 'yes' to accept the terms of the license.
Type 'no' to decline the terms of the license.
 
Do you accept the terms of the license? Yes

Since this is GPL, let us agree to the protocol when executing configure. py. Enter yes to continue.

It took 1 minute to complete successfully! Next, make. This process took 20 minutes and went quite well.
