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>>

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

#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

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-a ngstrom-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-a ngstrom-linux-gnueabi/include/bits/stdlib.h:70:3: error: #error "Assumed value of MB_LEN_MAX wrong"

make[2]: *** [glib-helper.o] Error 1

make[2]: Leaving directory `/home/yan/bluez-utils-3.36/common'

make[1]: *** [all-recursive] Error 1

make[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。
