一、下载库压缩包并解压
http://www.tildeslash.com/libzdb/#home
http://www.tildeslash.com/libzdb/dist/libzdb-3.2.2.tar.gz
tar -xvf /mnt/hgfs/share/libzdb-3.2.2.tar.gz -C ./二、导入交叉编译工具链环境变量
export PATH=$PATH:/opt/toolchain-3.4.x/bin/三、配置与安装
./configure --host=mipsel-linux-uclibc --prefix=/home/wxx/work/test/sqlite3/libzdb-3.2.2/install/问题1：
configure: error: cannot run test program while cross compiling解决问题1：
屏蔽掉所有出现该错误的地方（一共两处）：
?重新配置，出现问题2：
checking dynamic linker characteristics... (cached) GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
checking setjmp is available... configure: error: cross-compiling: please set 'libzdb_cv_setjmp_available=yes|no'
解决问题2：（重新添加配置参数--cache-file=mipsel-linux.cache）
echo libzdb_cv_setjmp_available=yes>>mipsel-linux.cache
echo libzdb_cv_vsnprintf_c11_conformant=yes>>mipsel-linux.cache
./configure --host=mipsel-linux-uclibc --prefix=/home/wxx/work/test/sqlite3/libzdb-3.2.2/install/ --cache-file=mipsel-linux.cache
重新配置出现问题3：
configure: WARNING: mysql_config is required to build libzdb with mysql
checking for oracle... checking if Oracle support is enabled... no
configure: error: No available database found or selected. Try configure --help解决问题3：
找到sqlite3的库路径并通过--with-sqlite来指定
./configure --host=mipsel-linux-uclibc --prefix=/home/wxx/work/test/sqlite3/libzdb-3.2.2/install/ --cache-file=mipsel-linux.cache --with-sqlite=/home/wxx/work/test/sqlite3/libzdb-3.2.2/sqlite3?重新配置出现问题4：
checking for /home/wxx/work/test/sqlite3/libzdb-3.2.2/sqlite3... configure: error: cannot check for file existence when cross compiling解决问题4：
屏蔽掉所有出现该问题的地方（检测环境交叉编译环境用，可以屏蔽掉）
?重新执行configure，成功：
四、编译安装
执行make出现问题5：
./tools/bin/filterh < src/zdb.h > zdb/zdb.h || exit 1
/bin/bash: ./tools/bin/filterh: cannot execute binary file: Exec format error
make: *** [Makefile:1251: zdb/zdb.h] Error 1
解决问题5：
重新打开一个终端，在另外一个地方重新解压压缩包，执行“./configure”生成适合在宿主机运行的“./tools/bin/filterh”，并替换交叉编译环境的“filterh”
重新执行make编译出现问题6：
libtool: compile: mipsel-linux-uclibc-gcc -DHAVE_CONFIG_H -I. -I./src -I/home/wxx/work/test/sqlite3/libzdb-3.2.2/sqlite3/include -Isrc -Isrc/util -Isrc/net -Isrc/db -Isrc/db/oracle -Isrc/exceptions -Wno-expansion-to-defined -Wno-nullability-completeness -Wno-address -Wno-pointer-sign -g -O2 -D_GNU_SOURCE -Wall -Wunused -Wno-unused-label -funsigned-char -c src/util/Vector.c -fPIC -DPIC -o src/util/.libs/Vector.o

解决问题6：
修改Makefile，在mipsel-linux-uclibc-gcc后面添加-std=c99
?重新执行make编译，出现问题7：

make[2]: *** [Makefile:428: pool.o] Error 1
后面的出错都是test目录的出错，可以忽略，直接执行make install生成库文件：
done?
