【问题描述】：

我刚刚通过使用非常标准的标志编译MongoDB v3.2 到scons，正如他们的wiki 中所记录的那样：

scons core --ssl --disable-warnings-as-errors
scons install --prefix /usr/local --disable-warnings-as-errors

这行得通，但二进制文件相当大，每个 200~500 MB：

# for x in mongo*; do file $x; du -sh $x; done
mongo: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=69333c37057636d730d21940550f6ecc45f7474b, not stripped
196M    mongo
mongod: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=1d1b8122b74729d042fee025a1bdb2999fe99fcc, not stripped
521M    mongod
mongoperf: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=5bfb47e755271efbdbed1de5b8130a41da5d026e, not stripped
511M    mongoperf
mongos: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=6409c6eb3d4f771fd9e41fbc87985384cc7b5453, not stripped
254M    mongos

这看起来很奇怪......就像我忘记了一些压缩标志或类似的东西。我相信这与file 命令输出中的not stripped 有关。我如何告诉scons 剥离/压缩它？

【问题讨论】：

只需运行strip mongod，也可以运行man strip 了解详情。 :-)
谢谢先生，效果很好:)

为了完整起见，如 cmets 中所述，来自 GNU 开发工具 的strip 是答案：

# for x in mongo*; do strip -s $x; file $x; du -sh $x; done                                                               
mongo: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=69333c37057636d730d21940550f6ecc45f7474b, stripped
16M     mongo
mongod: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=1d1b8122b74729d042fee025a1bdb2999fe99fcc, stripped
