zynq平台蓝牙协议栈移植

zynq平台蓝牙协议栈移植

需要在zynq平台添加蓝牙模块的支持，运行蓝牙相关的命令(hciconfig/hcitool)等，经过一番研究和多次实验之后，蓝牙协议栈最终移植成功。下面是相关库的具体编译过程和过程中遇到问题的解决方法。

./configure --prefix=/opt/bluez/bluez-libs-3.36 --host=arm-linux --target=arm-linux CC=arm-linux-gnueabihf-gcc
make
sudo make install

./configure --prefix=/opt/bluez/dbus-1.15.2 --host=arm-linux --target=arm-linux CC="arm-linux-gnueabihf-gcc -lexpat -I/opt/bluez/expat-2.5.0/include -L/opt/bluez/expat-2.5.0/lib" --cache-file=arm-linux.cache --with-x=no --enable-tests=no
make
sudo make install

#错误
checking for EXPAT... configure: error: Package requirements (expat) were not met:
No package 'expat' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables EXPAT_CFLAGS
and EXPAT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
#解决
export EXPAT_CFLAGS=/opt/bluez/expat-2.5.0/bin
export EXPAT_LIBS=/opt/bluez/expat-2.5.0/lib

注：当前的configure文件是没有选项参数可供我们配置使用，只能配置生成Makefile后，修改Makefile。

./configure

vi Makefile
# 这里的交叉编译工具（arm-none-linux-gnueabi-），大家要根据自己的实际情况来定，可能名字不一样
CROSS_COMPILE=arm-none-linux-gnueabi-
CC=$(CROSS_COMPILE)gcc
LDSHARED=$(CROSS_COMPILE)gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map
CPP=$(CROSS_COMPILE)gcc -E
AR=$(CROSS_COMPILE)ar
RANLIB=$(CROSS_COMPILE)ranlib

解决
交叉编译zlib库，并指定路径-I/opt/bluez/zlib-1.2.13/include -L/opt/bluez/zlib-1.2.13/lib
