bluez 交叉编译--测试通过（参考了网上的教程，并做了修改）

arm-linux-gcc 4.3.3
==========================================

我用到的几个库：
bluez-lib-3.36.tar.gz
expat-2.0.1.tar.gz
dbus-1.2.16.tar.gz
glib-2.22.4.tar.bz2
libusb-0.1.12.tar.gz
bluez-utils-3.36.tar.gz
====================================================

/opt/libs 和/opt/utils是我自己编译时用的路径，你可以随便的选取。
1，编译安装bluez-lib-3.36.tar.gz
这个库不需要什么依赖，直接解压，配置，编译然后安装即可。
#tar zxvf bluez-lib-3.36.tar.gz
#./configure --prefix=/opt/libs --host=arm-linux --target=arm-linux CC=arm-linux-gcc
#make
#make install

2，编译安装expat-2.0.1.tar.gz
这个库是后面的dbus依赖的，你也可以用libxml2来代替expat，官方网站上说dbus必须依赖于他们中的一个，我这里用的是expat-2.0.1.tar.gz。
#tar zxvf expat-2.0.1.tar.gz
#./configure --prefix=/opt/libs --host=arm-linux --target=arm-linux CC=arm-linux-gcc
#make
#make install

3，编译安装dbus-1.2.16.tar.gz
#tar zxvf dbus-1.2.16.tar.gz
#echo ac_cv_have_abstract_sockets=yes>arm-linux.cache
#./configure --prefix=/opt/libs --host=arm-linux --target=arm-linux CC="arm-linux-gcc -I/opt/libs/include -L/opt/libs/lib" --cache-file=arm-linux.cache --with-x=no
#make
#make install
=======================================================

4，编译安装glib-2.22.4.tar.bz2
#tar -zxjf glib-2.22.4.tar.bz2
#echo ac_cv_type_long_long=yes>arm-linux.cache
#echo glib_cv_stack_grows=no>>arm-linux.cache
#echo glib_cv_uscore=no>>arm-linux.cache
#echo c_cv_func_posix_getpwuid_r=yes>>arm-linux.cache
#echo ac_cv_func_posix_getgrgid_r=yes>>
#./configure --prefix=/opt/libs --host=arm-linux --target=arm-linux CC="arm-linux-gcc -I/opt/libs/include -L/opt/libs/lib" --cache-file=arm-linux.cache
有错误：
checking for posix getpwuid_r... configure: error: in `/home/yan/glib-2.22.4':
configure: error: cannot run test program while cross compiling
See `config.log' for more details.
#echo ac_cv_func_posix_getwuid_r=yes

checking for gmtime_r... (cached) yes
checking for posix getpwuid_r... (cached) yes
checking for posix getgrgid_r... configure: error: in `/home/yan/glib-2.22.4':
configure: error: cannot run test program while cross compiling
See `config.log' for more details.
#echo ac_cv_func_posix_getgrgid_r=yes>>arm-linux.chace
我的经验是以下三种方法都可以试试：
#echo ac_cv_func_posix_getwuid_r=yes
#echo ac_cv_func_posix_getwuid_r=yes>>
#echo ac_cv_func_posix_getwuid_r=yes>>arm-linux.cache
#make
有错误：
> giounix.c: In function `g_io_unix_read':
> giounix.c:181: `SSIZE_MAX' undeclared (first use in this function)
> giounix.c:181: (Each undeclared identifier is reported only once
> giounix.c:181: for each function it appears in.)
> make[3]: *** [giounix.lo] Error 1

[root@localhost glib-2.22.4]# find ./|grep giounix
./glib/giounix.c
./glib/.deps/giounix.Plo
./glib/.libs/giounix.o
./glib/giounix.lo

在 glib/giounix.c中加入：
#include <bits/posix1_lim.h>
#make install
如果出现找不到的东西

将安装好的lib/pkconfig/下面的文件拷贝到/usr/lib/pkconfig下

正确配置的

./configure --prefix=/opt/glib --host=arm-linux --target=arm-linux     CC="arm-linux-gcc -I/opt/libs/include -L/opt/libs/lib" --cache-file=arm-linux.cache ac_cv_have_abstract_sockets=yes ac_cv_type_long_long=yes glib_cv_stack_grows=no glib_cv_uscore=no ac_cv_func_posix_getpwuid_r=yes ac_cv_func_posix_getgrgid_r=yes

========================================================================================

编译安装bluez-utils-3.36.tar.gz  #tar zxvf bluez-utils-3.36.tar.gz  #./configure --prefix=/opt/libs --host=arm-linux --target=arm-linux     CC="arm-linux-gcc -I/opt/libs/include -L/opt/libs/lib" --disable-audio  #make有错误：In file included from /opt/toolchains/arm920t-eabi/lib/gcc/arm-angstrom-linux-gnueabi/4.1.2/../../../../arm-angstrom-linux-gnueabi/include/stdlib.h:969,                 from ../eglib/gmain.h:4,                 from ../eglib/glib.h:1,                 from glib-helper.c:41:/opt/toolchains/arm920t-eabi/lib/gcc/arm-angstrom-linux-gnueabi/4.1.2/../../../../arm-angstrom-linux-gnueabi/include/bits/stdlib.h:70:3: error: #error "Assumed value of MB_LEN_MAX wrong"make[2]: *** [glib-helper.o] Error 1make[2]: Leaving directory `/home/yan/bluez-utils-3.36/common'make[1]: *** [all-recursive] Error 1make[1]: Leaving directory `/home/yan/bluez-utils-3.36'make: *** [all] Error 2解决方法：[root@localhost opt]# find ./|grep stdlib.h./toolchains/arm920t-eabi/arm-angstrom-linux-gnueabi/include/stdlib.h./toolchains/arm920t-eabi/arm-angstrom-linux-gnueabi/include/bits/stdlib.h在/toolchains/arm920t-eabi/arm-angstrom-linux-gnueabi/include/bits/stdlib.h中将#define STDLIB_MB_LEN_MAX 16改为#define STDLIB_MB_LEN_MAX 1#make install==================================================== ./configure --prefix=/opt/bluez-utils --host=arm-linux --target=arm-linux     CC="arm-linux-gcc -I/opt/libs/include -L/opt/libs/lib" --disable-audio
这样Bluez协议栈就编译好了。
