哪位大虾能帮我分析下这个脚本

[zwjiong]

我在安装atk的时候出错，就是cofigure时就出错了
提示是这样的：
checking for GLIB - version >= 2.0.0...
*** 'pkg-config --modversion glib-2.0' returned 2.18.0, but GLIB (2.18.2)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
*** If pkg-config was wrong, set the environment variable PKG_CONFIG_PATH
*** to point to the correct configuration files

。。。。
首先我用的是UBUNTU8.10的，后来发现他内部是装了glib的2.18.2的，但是我又装了一个2.18.0在usr/local/lib下面，也可以从 'pkg-config --modversion glib-2.0' returned 2.18.0这里看出来，说明.pc文件也找到了～～～

然后去看他的configure文件，定为到出错的那部分
glib_config_major_version=`$PKG_CONFIG --modversion glib-2.0 | \
sed 's/\([0-9]*\).\([0-9]*\).\([0-9]*\)/\1/'`
glib_config_minor_version=`$PKG_CONFIG --modversion glib-2.0 | \
sed 's/\([0-9]*\).\([0-9]*\).\([0-9]*\)/\2/'`
glib_config_micro_version=`$PKG_CONFIG --modversion glib-2.0 | \
sed 's/\([0-9]*\).\([0-9]*\).\([0-9]*\)/\3/'`
这应该就是读glib版本号，我的理解，因为pkg_config --modversiong是读版本的命令
后面内嵌C代码的语句：
if ((glib_major_version != $glib_config_major_version) ||
(glib_minor_version != $glib_config_minor_version) ||
(glib_micro_version != $glib_config_micro_version))
{
printf("\n*** 'pkg-config --modversion glib-2.0' returned %d.%d.%d, but GLIB (%d.%d.%d)\n",
$glib_config_major_version, $glib_config_minor_version, $glib_config_micro_version,
glib_major_version, glib_minor_version, glib_micro_version);
printf ("*** was found! If pkg-config was correct, then it is best\n");
printf ("*** to remove the old version of GLib. You may also be able to fix the error\n");
printf("*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing\n");
printf("*** /etc/ld.so.conf. Make sure you have run ldconfig if that is\n");
printf("*** required on your system.\n");
printf("*** If pkg-config was wrong, set the environment variable PKG_CONFIG_PATH\n");
printf("*** to point to the correct configuration files\n");
}
应该说是判断到了版本出错了,所以执行后面的printf语句。我对shell语言不是很懂，C语言还算有点了解的，菜鸟一个，我不知道glib_micro_version和$glib_micro_version这2个变量到底有什么区别～～～这里很明显是这2个变量不一致才出错的

[xhy]

包管理器认为glib2版本是2.18.0，而实际上找到的是2.18.2，不一致了

[xhy]

后面内嵌的也不是什么C语言代码，只是比较像C

[zwjiong]

恩 我想分析下其中的过程，他应该通过'pkg-config --modversion glib-2.0读到2.18.0,这个版本是我自己手工安装的，在/usr/local/lib里面，我在终端下面也测试过是2.18.0,应该说明.pc也是找到了。但是我新利得里面装的是2.18.2，我就有问题了，configure是通过什么语句或者哪个环境变量知道我里面还有一个2.18.2的版本，因为据我了解的，程序的依赖性的查找都是通过.pc来实现的，那么我就必须要去读一个2.18.2版本的.pc才能知道版本有冲突，但是我也没有找到新里的安装的2.18.2版本的.pc文件，我是在usr/lib里面找的，新里的应该都装这个路径的把

应该是C吧，完整的是：

[xhy]

还真是C，用$打头变量的C...

[zwjiong]

大虾 能不能帮我解释下

[xhy]

卸载掉2.18.0

或者configure的时候指定这个path

[zwjiong]

我想知道他从那里知道我系统里面有2个glib版本，是通过什么样的操作

[zwjiong]

问题已经解决了~~~主要是configure里面又去读了glib库文件里面关于版本的全局变量，我之前装了2.18.0没有更新动态库的缓冲区，所以里面应该还是2.18.2的库，结果就冲突了

[shaufu]

能麻烦再请问一下如何更新动态库的缓冲区? 感谢

[x_programmer]

sudo ldconfig

就可以了
