Nightlies don't work on RHEL 6.5

[buster]

With regards to #9545 :

Rust is not only not working on RHEL5, but looks like it's also not running on RHEL6:

-bash-4.1# ./install.sh 
install: looking for install programs
install: found mkdir

install: found cut

This is actually the nightlies not working. The snapshots for linux are statically linked to libstdc++, while the nightlies are not.

[buster]

Oops, sorry for the confusion. Yes, the nightlies.
Will Rust after 0.11 not support RHEL6?

[alexcrichton]

Does RHEL6 support a C++11 compiler? If you install one, then rustc will likely work.

[buster]

I don't know. I actually only want to run a rust compiled program on RHEL6, not rust itself.
But it looks like i'll need to compile it on RHEL6 for that because of GLIBC.
I actually do the coding on Debian.

[alexcrichton]

In general rust programs themselves run almost wherever, but it'll likely be hindered by a newer libc if you're linking locally against one.

[buster]

So, how would i get my rust program working on RHEL6 then?
Is it possible to link against an older one or something like that? :)

[alexcrichton]

I would first try to compile the program and then run it on RHEL6 and see if an error happens, it's likely that it'll just work.

[buster]

Unfortunately not:
/lib64/libc.so.6: version GLIBC_2.14' not found`

[alexcrichton]

In that case you'll need to find a system with an older libc and compile on that system, or possibly find an older libc to compile against on the system where you're compiling

[buster]

I'll try to get rust compiled in a Centos 6.5 vagrant image and hope that works, then..
I hope that the compiler releases won't have such limitations since my work primarily still is on RHEL5 (starting to get to 6, but i won't see a RHEL7 for the next ~2 years)...

[buster]

So, installing g++ 4.7 on CentOS6.5 let me build rustc and compile the program... Thanks!

Nominating since we need to be able to support RHEL 6.
