交叉编译samba3.3.14遇到的错误

错误1

checking that the C compiler understands negative enum values... configure: error: in `/home/floyd.peng/wndr4700-db-buildroot.git/build_dir/target-powerpc_eglibc-2.13/samba':
configure: error: cannot run test program while cross compiling

出现该错误，我们的Makefile中有类似这样的语句

(cd $(PKG_BUILD_DIR)/source;./configure --target="$(ARCH)" --host="$(GNU_TARGET_NAME)）

我们需要添加一个环境变量samba_cv_CC_NEGATIVE_ENUM_VALUES到configure中

SAMBA_CONF_ENV:=samba_cv_CC_NEGATIVE_ENUM_VALUES=yes 
(cd $(PKG_BUILD_DIR)/source; $(SAMBA_CONF_ENV) ./configure --target="$(ARCH)" --host="$(GNU_TARGET_NAME)）

错误2

Linking bin/smbd
/home/floyd.peng/wndr4700-db-buildroot.git/staging_dir/toolchain-powerpc_gcc-4.5.1_eglibc-2.13/lib/gcc/powerpc-openwrt-linux-gnu/4.5.1/http://www.cnblogs.com/http://www.cnblogs.com/powerpc-openwrt-linux-gnu/bin/ld: cannot find -ltalloc
collect2: ld returned 1 exit status
make[3]: *** [bin/smbd] Error 1

解决办法，将$（PKG_BUILD_DIR）/source/bin中的libtalloc.so和libtalloc.a拷贝到交叉编译器中的lib目录下

错误3

mkdir: cannot create directory `///usr/local/samba': Permission denied
Failed to make directory ///usr/local/samba
make[3]: *** [installdirs] Error 1

通过--prefix指定正确的安装路径

./configure --prefix=/usr

错误4

mkdir: cannot create directory `///usr/lib/vfs': Permission denied
Failed to make directory ///usr/lib/vfs
make[3]: *** [installmodules] Error 

解决方法，在Makefile中的compile模块的$(MAKE)中添加

MODULESDIR="$(PKG_INSTALL_DIR)/usr/lib

附，package/samba下的Makefile参考
