Cannot build in debootstrap/chroot environment

[cko]

I tried to build the source in a debootstrap environment of Debian Wheezy (testing) and got the following error for make:

Can you provide some more information about how to set this up? I am not familiar with debootstrap.

[cko]

debootstrap is a tool which will install a Debian base system into a subdirectory of another, already installed system.

A short explanation on how to set it up can be found here:
http://serverfault.com/questions/23734/is-there-any-way-to-get-apt-to-install-packages-to-my-home-directory
Afaik it works on Debian and Ubuntu. Just replace lenny with wheezy, which is the current debian testing version and next stable one. It will require about 3GB hard disk.

I like it as a fast way to test somewhat experimental software a bit isolated from my main system, even though the combination of debootstrap and chroot is not an ultimate security feature (see for example: http://blog.technologyofcontent.com/2011/04/sandboxing-for-multi-tenant-applications/)

@cko If it wouldn't be too much trouble for you, would you mind trying to install and build LLVM on its own ( http://llvm.org/releases/ ) so we can get a rough idea of whether this is a Rust issue or an LLVM issue? (The version will probably not be exactly the same, so this is not a perfect test.)

[cko]

I set up a complete fresh environment. The rust build still produces the error above. The source of llvm 3.0 builds without problems.

[graydon]

This is really perplexing. I can reproduce it (in both wheezy and squeeze chroots) and have no idea why it's happening.

Is this still an issue? I haven't tested with debootstrap, but Rust does build fine in a chroot + namespaced container with the Arch Linux devtools. For some reason tidy.py breaks though...

triage visit, moving along

[lucab]

I'm currently nightly building rust from scratch in several pbuilders (which is a common debian automation of deboostrap+chroot), including wheezy and sid, and I haven't yet encountered any problems.
Given that this is now a year old, I think it can be closed.
