Comment 1 Thomas Petazzoni 2015-09-23 13:07:36 UTC

Thanks for your report!

It is not really libevent that fails to build, it's automake that uses some Perl modules that are not available on your system. On Debian/Ubuntu, the Thread/Queue.pm module is part of the perl-modules package which I believe is virtually installed on all Debian/Ubuntu systems.

Which distribution are you using? Does it have a package providing Thread/Queue.pm?

We should probably add a check in our dependencies for this perl module to be available (I don't think we want to make host-perl a dependency of host-automake).

Hi,

thx, using centos7, installed perl-Thread-Queue, and now it works

regards Florian

Comment 3 Thomas Petazzoni 2015-09-23 21:03:38 UTC

Thanks! We are anyway working on an improvement to Buildroot that will verify that this Perl module is installed, and if not, Buildroot will error out earlier and with a clearer error message.
