You should probably use nix dependencies themselves to bootstrap nix, instead of using system libraries.

@martinvahi

Without trying to figure out, if the smashed substance consists of a chicken or an egg, how could I bootstrap Nix by using packages that are maintained by Nix? Console examples welcome. :-)

@lucabrunox

By downloading the nix binaries for example and installing it.

That does not seem to work either.

I also tried to dowload the binaries by downloading some "zip", but
openSUSE
was not supported.

It seems to me that as of 2015_11 the Nix Package Manager is too experimental to be dependable. May be at the autumn of 2016 there's a chance. I also think that a package manager is something that should be very robust at bootstrapping and as of 2015_11 the Nix clearly fails to be robust at bootstrapping. I suggest that all the C++/C libraries that the Nix package manager depends on, are embedded to the Nix package manager source code so that it can be built by depending only GCC and Perl from the host system. Nothing should be downloaded at bootstrapping.

But, that is, of course, my subjective taste and opinion and everyone has an opinion. :-/

What is $LANG set as? Seems your local might be confusing perl.

The

echo $LANG

gives

en_US.utf8

#615 as far as binary bootstrapping goes, looks like a complete duplicate. I suppose leave this open until some triages source bootstrapping.

edit: which in turn leads to #599

Since #341 is inevitable now, I'll close this. No more perl in Nix, download-using-manifests.pl has been already rewritten in master. Sorry for the wait!
