hello示例程序编译出问题：
gcc -Wall -g helloworld.c -o helloworld `pkg-config --cflags gtk+-2.0` \
`pkg-config --libs gtk+-2.0`

gcc: pkg-config --cflags gtk+-2.0pkg-config --libs gtk+-2.0: 没有那个文件或目录
hello.c:1:21: gtk/gtk.h: 没有那个文件或目录

而pkg-config --cflags gtk+-2.0
和pkg-config --libs gtk+-2.0又能找到include等。

不太清楚是什么问题，可能是有些包没有装，比如libgtk2.0-dev，你到
/usr/include/gtk-2.0/gtk/ 下看看有没有gtk.h
还有，/usr/lib/pkgconfig/下看看有没有gtk-2.0.pc文件
