Ubuntu下ZS5.5打开之后是空白屏幕的解决方案

安装了ubuntu之后,立马安装上了zendstudio 5.5 结果出现空白屏幕,以为是不兼容呢。也就没注意。然后安装了一个 ZS for eclipse 6,一切正常。更加肯定了自己的机器与ZS5的不兼容。

可是,我的屏幕只有12。1,在ZS6下面,能够给我写代码的地方太小了。。。。简直无法下手。

于是就想怎么解决5。5的问题。

想不到啊。一直劝别人:内事不决问百度外事不决问google的,象ZS这种进口软件,我居然没有想到问问google。不过,我问了Vampire(政委)同学,他采用了我教别人的方法,然后给了我条答案。

不敢独享。。。

Zend Studio starts up with an empty window, or other GUI problems, due to XGL-Compiz/Beryl (with JRE) compatibility issues

Article #241
Product: Zend Studio

 

Symptoms




When running Zend Studio:
1. The ZS's main window comes up totally empty.
2. Sometimes the window has some of the frames painted, but the rest of the window is empty.
3. In the empty ZS window the mouse cursor is changing while moving around the window (as if there are objects: like buttons and other objects).
4. There were erratic mouse/window movements reported.

Summary




Zend Studio starts up with various windowing GUI problems in some linux distros, while using the XGL-Compiz/Beryl product.

Cause




1. Incompatibility between the XGL environment, the JRE, and the Zend Studio Client.
2. The decoration in the 3D environment clashes with the Java Runtime and distorts the operation and visualization of the Zend Studio client's window.

Workaround




There are two ways to execute Zend Studio, by running the ZDE script, and by running the runStudio_unix.sh script, both are in the bin directory of zend studio
(usually /usr/local/Zend/ZendStudio-/bin)

The following workarounds may be used, but there is no guarantee how well or how long it might work for you in your environment.

  •  
  • modification of ZDE script for xgl:
  •  


1. Open your ZDE script with your favorite editor
2. add the next line of code at line 1693.
options="$options -Dawt.toolkit=sun.awt.motif.MToolkit"

for example:
1693:
1694: debugOut ""
1695: unset POSIXLY_CORRECT
1696: if [ $DO_NOT_FORK ]

becomes:
1693: options="$options -Dawt.toolkit=sun.awt.motif.MToolkit"
1694: debugOut ""
1695: unset POSIXLY_CORRECT
1696: if [ $DO_NOT_FORK ]

3. Save the file.

  •  
  • modification of runStudio_unix.sh script for xgl:
  •  


1. open the the file in your favorite editor.
2. modify the java execution line,
the line starts with: ../jre/bin/java -Xms16m -Xmx256m -cp...
change it to: ../jre/bin/java -Dawt.toolkit=sun.awt.motif.MToolkit -Xms16m -Xmx256m -cp...
^^^^^^^^^^^^^^^^^^^^^^^^^^
as you can see, the only difference is an extra parameter to the java program.
3. Save the file.

Another solution




the AWT_TOOLKIT environment variable can be set in order for Java to choose a working AWT Toolkit.

export AWT_TOOLKIT="MToolkit"

In most Linux Distributions it's enough to append this line to /etc/profile.

The information in this article applies to




Zend Studio Client

Common Problems



On some amd64 based systems, the motif toolkit will not work, complaining that "current locale is not supported in X11".

A solution for this case is to set the XLOCALELIBDIR environment variable to the X11 32 bit locale
directory of your system.
Ubuntu Distribution users will find it at: /usr/lib32/X11/locale.

Ubuntu users can use the following as a startup-script:
#!/bin/bash
export AWT_TOOLKIT=MToolkit
export XLOCALELIBDIR=/usr/lib32/X11/locale
exec ZendStudio-5.5.0/Zend_Development_Environment

关于PHP版本升级的一些相关问题

PHP版本一直在更新,同样我们的代码也会随着服务器上的PHP版本的更新而不得不进行更改,但每次PHP的更新,几乎只是显示fix了多少多少BUG,但究竟会在版本升级的时候带来哪些问题,自己一点也不清楚 。

其实翻开PHP的手册,你也能找到这些,现在方便了,到我的博客上下载乔楚编译的最新的手册,翻开左侧树的最后一个节点:Appendices,找到:

大小: 11.61 K
尺寸: 305 x 89
浏览: 1927 次
点击打开新窗口浏览全图

展开这三个节点,你会看到在版本更新的时候,PHP的核心加了哪些方法,去除了哪些函数(事实上这很重要,或许在你以前的项目里一直在采用XXX方法,但新版本去掉了,很可能你的程序就不能再运行了。。。)

当然你更应该看的是:Changes in reference handling,这里面介绍的是一些老的代码写法和应用在新的代码里会出错的例子,如果你的代码里沿用了这些旧的方法,那么,你先考虑一下升级的代价吧。
