用arm-linux-gcc编译蓝牙程序时出现了如下错误，已经将libbluetooth这个库放到/usr/local/arm/3.4.1/arm-linux/lib中，

请高手们指教怎么解决上面的错误，安装了libglib2.0-0_2.12.4-2_arm这个库也没有解决问题。

checkpoint：

1）libbluetooth 使用该交叉编译器编译的吗？

2）你的蓝牙程序跟这个libbluetooth是匹配的吗，也就是说使用这个库的API进行编程的吗？


BTW，不需要把libbluetooth库放到交叉编译器的 那个lib目录下，
对于库的链接，Linux有它的方法:

 -L -lbluetooth

就是找此目录下的libbluetooth.so或者libbluetooth.a去链接

库应该要用交叉编译工具编译

使用不同的编译器编译应用程序和库会造成这个问题
