pulseaudio的交叉编译

在/etc/profile里导入

 export PATH==$PATH:/home/jack/arm-linux-gcc/x-tools/arm-unknown-linux-gnueabi/bin

配置参数

 ./configure CC=arm-linux-gcc CXX=arm-linux-g++ --host=arm-unknown-linux-gnueabi --prefix=/home/jack/Ekho_work/ekho CPPFLAGS=-I/home/jack/Ekho_work/ekho/include LDFLAGS=-L/home/jack/Ekho_work/ekho/lib CFLAGS=-I/home/jack/Ekho_work/ekho/include

开发环境

 ubuntu-11.04

./configure遇到的问题

1.问题一

 checking for m4... no

 configure: error: m4 missing

 solution：

 http://ftp.gnu.org/gnu/m4/m4-1.4.10

 在终端将环境导入export PATH=$PATH:/home/jack/Ekho_work/ekho/bin

2.问题二

 ./configure: line : intltool-update: command not found

 checking for intltool >= 0.35.... found

 configure: error: Your intltool is too old. You need intltool 0.35. or later.

 solution：

 intltool-0.40..tar.bz2

3.问题三

 configure: error: Unable to find libltdl version . Makes sure you have libtool 2.4 or later installed.

 solution：

 libtool-2.4..tar.gz

4.问题四

 configure: error: Package requirements ( json >= 0.9 ) were not met:

 No package 'json' found

 solution：

 json-c-0.10-nodoc.tar.gz

 在/etc/profile里导入export PKG_CONFIG_PATH=/home/jack/Ekho_work/ekho/lib/pkgconfig:$PKG_CONFIG_PATH

5.问题五

 configure: error: Package requirements ( sndfile >= 1.0. ) were not met:

 No package 'sndfile' found

 solution：

 libsndfile-1.0..tar.gz

make遇到的问题

1.问题一

 /home/jack/Ekho_work/ekho/include/json/json.h::: error: json_object_iterator.h: No such file or directory

 solution：

 将/home/jack/Ekho/package_4/json-c-0.10/json_object_iterator.h拷贝到/home/jack/Ekho_work/ekho/include/json下

2.问题二

 /home/jack/Ekho_work/ekho/lib/libjson.so: undefined reference to `rpl_malloc'

 collect2: ld returned  exit status

 /home/jack/Ekho_work/ekho/lib/libjson.so: undefined reference to `rpl_malloc'

 collect2: ld returned  exit status

 solution：

 在/home/jack/Ekho/package_4/json-c-0.10/config.h文件里注释掉

 //#define malloc rpl_malloc

 //#define realloc rpl_realloc

 这两行，重新make -j8 ，make install

以上通过测试
