I was trying to build Erlang int the latest RC (2013.02-rc3) for arm.
It did not recognize the platform correctly and, as a result, did not build.
Here is an excerpt from the log file:

As the comment says, this is erlang for the host (which is a dependency of
erlang for the target).

You didn't paste any error message, what exactly is not working?

> (cd /root/buildroot-2013.02-rc3/output/build/host-erlang-R15B01/ && rm -rf

Please don't build as root!

The log you've copy/pasted shows the configuration step of the host-erlang
package, i.e when we build Erlang for your development PC. Therefore, it is
perfectly normal that the detected host platform is i686-pc-linux-gnu.

Could you instead post the real build failure you're seeing?

1. Sorry for misunderstanding - I will provide exact failure as soon as my
current build will finish.

2. I build as root because I am building on separate VM, which was created
solely for buildroot - this way I can archive / transfer / backup image +
toolchain easier.

So, it looks like it does not have zlib in the host environment ...
I installed it on the host machine, but it does not help.

I've just tested building erlang for ARM with the latest Buildroot, and it
builds fine here. I've tested both a dynamic library build and a static library
build, and both went fine.

Could you post the Buildroot .config that exhibits the problem? Also, do you
have zlib installed on your host machine? And its development files?

Looks to me like host-erlang should either depend on host-zlib, or set the
--disable-shared-zlib option.

I had a look at this before replying, and the build I tested have been done on
a machine where the zlib development files are not installed. host-erlang
automatically detects that zlib is not available, and builds its own copy of
it. So I concluded that this could not have been the origin of the bug.

Hm, indeed --enable-shared-zlib defaults to no, so that can't be it.

I also haven't been able to reproduce.

Timofei, can you attach the failing .config?

Well - I was building it 3 month ago on buildroot-2013.02-rc3 ...
Today / tomorrow I will try to reproduce it on the that buildroot and then
attach the .config. Sorry for being slow ...

The bug report never provided the .config, and I've again tested that Erlang
builds fine for ARM. Moreover, it's been a while since we haven't had an
autobuilder failure on erlang, as far as I can remember.

While there might probably be an issue, the bug report hasn't provided enough
detail to investigate. Feel free to reopen with more details (at the minimum
the tested Buildroot version *and* configuration file). Thanks!
