1、前言
本文主要讲述在linux环境下进行编译wxpython,在windows下面安装wxpython很简单,只要下载,然后直接执行exe文件,下一步下一步即可安装,在linux下面,则具有很多步骤。
wxpython下载地址为:
http://wxpython.org/download.php
具体的源码下载路径在最下面的位置,名称为wxPython-src,点击即可下载。下载的文件名称为wxPython-src-3.0.2.0.tar.bz2.
2、解压
进行解压:
[root@FTP ~]# tar -jxvf wxPython-src-3.0.2.0.tar.bz2
3、安装依赖包
gtk2,gtk2-devel,python-devel,tk,tk-devel,gstreamer,gstreamer-devel,mesa-libGL-devel,
mesa-libGLU-devel,mesa-libGLU,mesa-libGL,libSM,libSM-devel,gstreamer-plugins-base-devel
最好是利用yum进行安装。。否则会崩溃的
4、编译
新建一个临时路径来保存编译的结果,如下所示:
[root@FTP wxPython-src-3.0.2.0]# mkdir bld
[root@FTP wxPython-src-3.0.2.0]# cd bld
[root@FTP bld]# ../configure --prefix=/usr/local/pythonwxpython --with-gtk --with-gnomeprint
--with-opengl --enable-debug --enable-geometry --enable-graphics_ctx --enable-sound --with-sdl
--enable-mediactrl --enable-display --disable-debugreport --enable-unicode --with-libjpeg=builtin
--with-libpng=builtin --with-libtiff=builtin --with-zlib=builtin
新建bld来保存编译的结果,主要是由于编译的时候,占用的空间有1G多,所以需要用一个新的目录进行编译,注意上面configure前面有两个点。
编译结果如下:
进行安装:
make && make install
消耗的时间和占用的空间如下:--编译需要8分钟的样子,估计服务器会快很多
[root@FTP local]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_ftp-lv_root
9.9G 6.1G 3.3G 66% /
tmpfs 387M 0 387M 0% /dev/shm
/dev/sda1 485M 32M 428M 7% /boot
[root@FTP local]# date
Tue Apr 5 13:07:07 EDT 2016
[root@FTP local]# date
Tue Apr 5 13:14:56 EDT 2016
[root@FTP local]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_ftp-lv_root
9.9G 8.1G 1.3G 87% /
tmpfs 387M 0 387M 0% /dev/shm
/dev/sda1 485M 32M 428M 7% /boot
进行安装wxpython:--WX_CONFIG就是前面编译configure的路径
[root@FTP wxPython]# python setup.py build_ext --inplace --debug WX_CONFIG=/usr/local/pythonwxpython/bin/wx-config
安装之后,设置wxpython的环境变量:
export PYTHONPATH="/usr/local/wxPython"
export LD_LIBRARY_PATH="/usr/local/pythonwxpython/lib
可以添加在用户加目录中,另外必须将wxpython添加到pythonpath中,如下:
[root@FTP wxPython-src-3.0.2.0]# cp -r wxPython /usr/local/wxPython/
拷贝主要是为了对应上面的PYTHONPATH
问题
1、重新编译
在进行重新编译的时候,必须先进行清除前面编译的文件,使用的命令如下:
make distclean
如果使用makeclean,是不可以的,报错信息如下:
configure: error: source directory already configured; run "make distclean" there first
configure: error: ../../../src/tiff/configure failed for src/tiff
如果使用上面的命令不能清除,那么还是重新解压进行编译吧
2、导入wx模块出错
导入wx模块的时候,出错,出错内容如下:
>>> import wx
Traceback (most recent call last):
File "", line 1, in
File "wx/__init__.py", line 45, in
from wx._core import *
File "wx/_core.py", line 4, in
import _core_
ImportError: libwx_gtk2u_xrc-3.0.so.0: cannot open shared object file: No such file or directory
设置环境变量LD_LIBRARY_PATH:
[root@FTP wxPython]# cat ~/.bash_profile |grep LD
export LD_LIBRARY_PATH="/usr/local/pythonwxpython/lib
将环境变量写在用户文件中,从而每次都可以直接使用。
3、在别的路径无法导入wx模块
在别的路径导入wx模块的时候,报错如下:
[root@FTP ~]# python
Python 2.7.11 (default, Apr 5 2016, 12:30:11)
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import wx
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named wx
主要是将wxpython加入到模块的搜索路径中,只要修改环境变量即可,如下:
[root@FTP wxPython-src-3.0.2.0]# cp -r wxPython /usr/local/wxPython
[root@FTP wxPython-src-3.0.2.0]# cat ~/.bash_profile |grep PYTHON
export PYTHONPATH="/usr/local/wxPython"
4、报错gtk未找到
具体的报错内容如下:
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK+ is incorrectly installed.
configure: error:
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent.
主要查看是否安装了gtk2和gtk2-devel包,安装上这两个包即可
有人说需要安装pkgconfig包,本系统中已经安装了这个包,所以未进行测试。
5、报错gstream未找到
具体的报错内容如下:
configure: No package 'gstreamer-1.0' found
configure: error: no gstreamer-1.0 >= 1.0.0 (GStreamer) found
主要报错是因为缺少几个包,具体的包如下:
[root@FTP demo]# rpm -qa |grep ^gstreamer*
gstreamer-plugins-base-0.10.29-1.el6.x86_64
gstreamer-0.10.29-1.el6.x86_64
gstreamer-devel-0.10.29-1.el6.x86_64
gstreamer-plugins-base-devel-0.10.29-1.el6.x86_64
gstreamer-tools-0.10.29-1.el6.x86_64
看缺少什么包,然后就安装什么依赖包。
6、报错opengl库未找到
具体的报错内容如下:
configure: error: OpenGL libraries not available
主要缺少的依赖库如下:
[root@FTP demo]# rpm -qa|egrep "mesa-libGL-devel|mesa-libGLU-devel"
mesa-libGL-devel-7.11-3.el6.x86_64
mesa-libGLU-devel-7.11-3.el6.x86_64
注意没有带devel的包也要相应的装上。
7、在进行安装wxpython的时候出现很多报错
在进行安装wxpython的时候,如果出现很多编译错误,直接加上参数BUILD_GLCANVAS=0,也可以直接忽略。
[root@FTP wxPython]# python setup.py build_ext --inplace --debug WX_CONFIG=/usr/local/pythonwxpython/bin/wx-config BUILD_GLCANVAS=0
8、其他的问题
如果出现其他的问题的话,基本都是依赖包的问题,依次进行安装上述的依赖包即可。
