我使用的是当前最新版的4.5.20（点击下载）。

（一）解压
linux:/home/work/db # tar -zxf db-4.5.20.tar.gz linux:/home/work/db # cd db-4.5.20/ linux:/home/work/db/db-4.5.20 # ls . db_checkpoint db_upgrade libdb_java README .. db_deadlock db_verify LICENSE rep btree db_dump dist lock repmgr build_unix db_dump185 docs log rpc_client build_vxworks db_hotbackup env mod_db4 rpc_server build_windows dbinc examples_c mp sequence clib dbinc_auto examples_cxx mutex tcl common db_load examples_java os test crypto dbm fileops os_vxworks txn cxx db_printlog hash os_windows xa db db_recover hmac perl db185 dbreg hsearch php_db4 db_archive db_stat java qam
docs目录下有我们需要的文档，包括快速入门、各种语言的API手册等资料。
（二）配置和编译
建立一个脚本以方便配置。由于unix/linux编译时的工作路径必须是build_unix，因此我们需要在build_unix目录下创建脚本。
我创建了一个名为myconfig的脚本，内容如下：
linux:/home/work/db/db-4.5.20/build_unix # cat -n myconfig
1 #!/bin/sh
2
3 CC=arm-elf-gcc
4 CFLAGS="-Os -D__uClinux__ -fno-builtin -I/home/uClinux-dist/linux-2.4.x/include -I/home/uClinux-dist/lib/uClibc/include -I/home/uClinux-dist/lib/uClibc/include/../ "
5 LDFLAGS="-Wl,-elf2flt -Wl,-move-rodata -L/home/uClinux-dist/lib/uClibc/lib -L/home/uClinux-dist/lib/uClibc/lib/../ -lc "
6 ../dist/configure
7 --prefix=/home/work/db/Berkeley.DB

23 --disable-java
24 --disable-mingw
25 --disable-o_direct
26 --disable-posixmutexes
27 --disable-pthread_api
28 --disable-rpc
29 --disable-smallbuild
30 --disable-tcl
31 --disable-test
32 --disable-uimutexes
33 --enable-umrw
34 --disable-shared
35 --enable-static
36 --enable-fast-install
37 --disable-libtool-lock
38 --disable-largefile
关于configure配置参数的含义，可以运行”../dist/configure –help”查看帮助，这里不再介绍。
要强调的一点是uClibc只能用静态编译，因此一定要选择–disable-shared。
接着执行./myconfig运行配置并编译安装函数库：
