Linking with gcc failed every time I use foreign function interface

[tprodanov]

I cannot run any code containing foreign function interfaces, every time getting linking with gcc failed error.
For example I tried to compile example from the tutorial, but it fails with error:

error: linking with `gcc` failed: exit code: 1

Just now I reinstalled mingw and rust, following this instruction, but it didn't help.
I am running in Windows 7, Mingw 4.8.1, and rustc -v gives this:

rustc 0.11.0-pre-nightly (bb5695b95c288c442dbe528f7e1c1b08f79f033d 2014-06-29 23

The problem is hidden in there: cannot find -lsnappy. Do you have the snappy library installed on your system?

[tprodanov]

I just pasted this folder to the same folder with rust file. How should I install it?

[alexcrichton]

Closing, this is intended behavior until libsnappy is installed. You'll have to google around to see how to build it and then pass -L to the compiler to point at the directory the library is located.
