标签：end 重新编译 一个 配置 gets failed ica 服务器 自带
今天开始正式干活了
第一件事就是给我一个全志tina的sdk和板子，他们说这个sdk好像有点问题，编译有个错误没法通过，要求我这周就要把sdk弄好，并编译出img把板子跑起来。
编译的时候报错
果然是有坑，
$ tar -xvf Homlet-Tina-H2_H3 $ cd Homlet-Tina-H2_H3 $ source build/envsetup.sh $ lunch dolphin_p1-tina $ make –j4
编译15分钟之后就报错了

看报错是从encoding.h里面找不到被包含的头文件
打开/usr/include/libxml2/libxml/encoding.h看一下

看到有个宏
LIBXML_ICU_ENABLED
但是查看系统配置里面对这个宏的定义
查看/usr/include/libxml2/libxml/xmlversion.h里面对这个宏的定义的解释，是对icu的支持。
/** 281 * LIBXML_ICU_ENABLED: 282 * 283 * Whether icu support is available 284 */ 285 #if 1 286 #define LIBXML_ICU_ENABLED 287 #endif
但是本身目前的需求是不需要支持的，可以在这里屏蔽掉，但是这个是编译服务器的头文件，没有权限修改。
另外为了编译某个项目把公用的头文件屏蔽功能对其他项目有这个需求的可能会有影响。
本身sdk都带有所以依赖库的源码包，需要做的是将依赖的头文件目录路径更改到自带的路径下。
下面的问题就变成了怎么找到到这个头文件包含的路径设置的地方进行修改。
整个sdk编译走的都是makefile结构，头文件路径有些是从父级继承下来的，有些是子源码目录自己添加的。
总之指向/usr/include/libxml2/libxml的地方就是会有问题，
查看出问题源码下面的Makefile发现了CPPFLAGS里面就是包含了整个路劲
Makefile文件来自于configure之后产生，所以这个应该是和configure有关
于是去查找源码目录下的configure文件果然发现了configure.as写死了包含这个路径
if test "x$build_datasource_xml" = "xyes"; then AC_DEFINE(_MGNCSDB_DATASOURCE, 1, [Define if support datasource]) AC_DEFINE(_MGNCSDB_XML, 1, [Define if support xml datasource]) CPPFLAGS="$CPPFLAGS -I/usr/include/libxml2" fi
这就是问题的关键，把这个头文件地址改到自己指定的libxml2目录就可以了
CPPFLAGS="$CPPFLAGS -I../../../../package/allwinner/liballwinner_tina/liballwinner/LIBRARY/EXTERNAL/include/libxml"
重新编译就好了
