我认真的读了5C中关于上外网的帖子,也 下载了Roc-client-0.2.1,解压缩成功,但当我使用./configure进行配置检查的时候,有如此信息显示:

Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
configure: error: Package requirements (gtk+-2.0 >= 2.0.0) were not met:



Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables PACKAGE_CFLAGS
and PACKAGE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

我 也 不 明白杂设置环境变量,才入gate,请教了 哈!
