[ryanra]

Try with 1.6.0-nightly and let me know what happens.

[ryanra]

Hmmm, I've verified it works with rustc 1.6.0-nightly (1e3e7e73c 2015-11-07). Could you grab that and try it?

[anujfulia]

with version rustc 1.6.0-nightly (1e3e7e73c 2015-11-07)

it shows following error :

[ryanra]

This seems like a similar problem to: #5

What does ld -v output for you?

[anujfulia]

GNU ld (GNU Binutils for Ubuntu) 2.24

[ryanra]

Hmm, yeah, the OP in #5 had the same issue using version 2.24 of binutils. Would it be possible for you to get 2.25? That should fix the problem.

[anujfulia]

I am using ubuntu 14.04 . If you are using newer version, i will also upgrade.

[ryanra]

From what I gather, 15.04 has that version of binutils. You might also be able to keep your current version of ubuntu and just upgrade binutils. I'm going to close this thread though as the problem should be solved by getting the right version of binutils.
