官網上說：“Before you can build PyQt4 you must have already built and installed SIP” 意思是說必須先安裝SIP，於是也下載了SIP。
解壓SIP壓縮包，進入原始碼目錄，開啟README，說是當前目錄下有一個build.py，結果我沒有找到。但找到了一個configure.py的程式碼。於是我執行它
| 1 |
$ python configure.py
|
正常完成，並生成了Makefile。我下意識地執行make，結果：
| 1 2 3 4 5 6 7 8 |
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 1make[1]: Leaving directory `/home/hevake_lcj/Install/qt-downloads/sip-4.15.3/siplib'
make: *** [all] Error 2

通常這種問題出在系統沒有安裝元件的開發板，只提供了庫檔案，並沒有提供對應的標頭檔案，不能進行二次開發。解決檔案就是安裝python-devel

$ sudo yum install python-devel

完成安裝。再make，順利通過編譯。再sudo make install，也很順利。測試是否完成安裝：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
$ sip -h
Usage:
sip [-h] [-V] [-a file] [-b file] [-c dir] [-d file] [-e] [-g] [-I dir] [-j #] [-k] [-m file] [-o] [-p module] [-P] [-r] [-s suffix] [-t tag] [-T] [-w] [-x feature] [-X id:file] [-z file] [file]
where:
-h display this help message
-V display the sip version number
-a file the name of the QScintilla API file [default not generated]
-b file the name of the build file [default none generated]
-c dir the name of the code directory [default not generated]
-d file the name of the documentation file (deprecated) [default not generated]
-e enable support for exceptions [default disabled]
-g always release and reacquire the GIL [default only when specified]
-I dir look in this directory when including files
-j # split the generated code into # files [default 1 per class]
-k support keyword arguments in functions and methods
-m file the name of the XML export file [default not generated]
-o enable the automatic generation of docstrings [default disabled]
-p module the name of the consolidated module that this is a component of
-P enable the protected/public hack
-r generate code with tracing enabled [default disabled]
-s suffix the suffix to use for C or C++ source files [default ".c" or ".cpp"]
-t tag the version/platform to generate code for
-T disable the timestamp in the header of generated files
-w enable warning messages
-x feature this feature is disabled
-X id:file create the extracts for an id in a file
-z file the name of a file containing more command line flags
file the name of the specification file [default stdin]

安裝OK。
解壓下載的：PyQt-x11-gpl-4.10.3.tar.gz
ImportError: No module named QtWebKit
進入原始碼目錄，開啟README，按說明的步驟：先執行configure-ng.py指令碼，然後make，make install。
因為我在使用 eric4 的時候 出現錯誤
原因是在編譯 PyQt 的時候 沒有安裝 QtWebKit 導致沒有編譯那個模組
所以在編譯之前 yum install qtwebkit

$ python configure-ng.py

由於這是GPL，所以在執行configure-ng.py時讓我們同意協議。輸入yes繼續。
用了1min順利完成！接著make，這個過程有一點長，花了20分鐘，很順利。
