SIP 설치
PyQt를 설치하기 전에 SIP를 먼저 설치해야합니다. 저는 sip-4.17.tar.gz로 설치했습니다.
python configure.py
python configure.py를 입력합니다.
root@localhost:/home/westporch/Downloads/sip-4.17# chmod 655 configure.py; python configure.py This is SIP 4.17 for Python 2.7.9 on linux2. The SIP code generator will be installed in /usr/bin. The sip module will be installed in /usr/lib/python2.7/dist-packages. The sip.h header file will be installed in /usr/include/python2.7. The default directory to install .sip files in is /usr/share/sip. Creating siplib/sip.h... Creating siplib/siplib.c... Creating siplib/siplib.sbf... Creating sipconfig.py... Creating top level Makefile... Creating sip code generator Makefile... Creating sip module Makefile...
make
make를 실행합니다.

python-dev 설치가 끝나면 다시 make를 실행합니다.

PyQt 설치
PyQt4를 다운 받습니다. PyQt-x11-gpl-4.11.4.tar.gz 버전으로 설치하겠습니다.
python configure.py
python configure.py을 실행하고 yes를 입력합니다.

PyQt 설치 확인
PyQt를 설치할 때 python configure.py, make, make install을 실행한 폴더에서 하위 폴더인 examples/widgets로 이동합니다. 제 경로는 다음과 같습니다.
root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets# pwd /home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets# root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets# ls README calendarwidget.py groupbox.py lineedits.py shapedclock.py styles.py tooltips analogclock.py charactermap.py icons movie sliders.py stylesheet wiggly.py calculator.py digitalclock.py imageviewer.py scribble.py spinboxes.py tetrix.py windowflags.py root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets#
python digitalclock.py를 실행했을 때 GUI 화면이 나타나면 PyQt가 제대로 설치된 것입니다.
Qt Designer 설치
Qt Designer는 GUI 환경을 디자인하는데 도움을 줍니다. apt-get install qt4-designer를 실행하여 Qt Designer를 설치합니다.
cannot connect to X server :0 메시지가 발생할 경우
아래와 같은 메시지가 출력되면서 PyQt의 GUI 화면이 나타나지 않는 경우가 있습니다.
root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets# python digitalclock.py No protocol specified digitalclock.py: cannot connect to X server :0 root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets#
이럴 때는 su 명령을 사용하기 전에 xhost +를 먼저 입력해야 합니다. 아래 화면을 참고해주세요.
westporch@localhost:~$ xhost + access control disabled, clients can connect from any host westporch@localhost:~$ su root 암호: root@localhost:/home/westporch# root@localhost:/home/westporch# cd /home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets# root@localhost:/home/westporch/Downloads/PyQt-x11-gpl-4.11.4/examples/widgets# python digitalclock.py
