In Ubuntu 20.04, using Buildroot, which was working fine some days ago, I get the following error message:
Your Perl installation is not complete enough; at least the following modules are missing: Data::Dumper ExtUtils::MakeMaker Thread::Queue Math::BigInt Math::BigRat Executing perl -V I get:
Can't locate Config.pm: /usr/local/lib/x86_64-linux-gnu/perl/5.30.0/Config.pm: Permiso denegado. BEGIN failed--compilation aborted. Folder '/usr/local/lib/x86_64-linux-gnu' doesn't exist in my system (it does in /usr/lib).
I think it could be related to a failed build and installation attempt I did yesterday, which installed some 3rd party dependencies to /usr/local subfolders, and finally failed due to missing files under /usr/local: cc1plus: error: /usr/local/include/x86_64-linux-gnu: Permission denied (real problem is that the folder doesn't exist, not permission).
I don't know how it messed my system, the problem with Perl is, for now, the only side consecuence I've found, and I can't find any useful info on how to solve it.
I've tried to reinstall perl and its dependencies (perl-base, perl-modules, etc.) with 'apt', but no luck.
If I execute perl -V with sudo I do have some info, I paste it here in case it is useful:
