(Yes, it's messy. This is on a system I don't control, which is why I'm using brew in the first place.)

Description of issue

Installation of elfutils (from source) always fails. (It's a dependency: vim→ruby→rust→elfutils.)

brew gist-log here. The key error seems to be:

configure:8804: error: __cxa_demangle not found in libstdc++, use --disable-demangler to disable demangler support.

This is a linuxbrew installation without sudo, in a non-standard prefix. I know it's not supported, but I'd appreciate any help pointing me to the root of this issue or a fix. I'm not great with compilers.

I got the same issue here, and my work around is to use "brew install --force-bottle elfutils" to install binaries instead of building from the source. I think the solution is to add "--disable-demangler" to the config file elfutils.rb, but I am not able to do it.
