节点：从源代码构建到二进制分发

Question

I have downloaded node 0.10.31 source and built on my Linux machine using same steps mentioned in wiki. The source is just as it is and no changes made at all. The build is successful but when I compare bin/node file size with the one from binary downloaded there is around 900kb difference (built from source is bigger).

What is the reason?

Did I miss any optimizer or special config? Actually I wanted to use locally build node (after some change) in production. I just don't want to miss some settings here.

My environment:

gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)

Python 2.6.6 (r266:84292, Nov 21 2013, 10:50:32)

Answer 1

You can try and strip out debugging symbols. Eg,

$ strip node

Debugging symbols are pieces of information embedded in an object file, and useful for debugging purposes. Unfortunately, they take up space in the file, so if you do not plan debugging the node interpreter itself you could get rid of them.

Moreover, please check out strip 's manual page for a full list of choices when discarding symbols from object files.
