Re^2: EXTERN.h missing when compiling on OpenWrt

I can install perlbase-cpan and when I then add perlbase-unicore (the dependencies are not properly reflected in the packages) I do not have a cpan-script, but I can run

perl -MCPAN -e shell
[download]

However:

CPAN.pm requires configuration, but most of it can be done automatical
+ly.
If you answer 'no' below, you will enter an interactive dialog for eac
+h
configuration option instead.

Would you like to configure as much as possible automatically? [yes] y
+es

 <install_help>

Warning: You do not have write permission for Perl library directories

To install modules, you need to configure a local Perl library directo
+ry or
escalate your privileges.  CPAN can help you by bootstrapping the loca
+l::lib
module or by configuring itself to use 'sudo' (if available).  You may

resolve this problem manually if you need to customize your setup.

What approach do you want?  (Choose 'local::lib', 'sudo' or 'manual')
 [local::lib]

On systems with a small memory footprint, use cpanm, Re^2: Should cpanminus be part of the standard Perl release?.	[reply]

Also, if you really want to stay with `cpan`, you can (manually) install CPAN::SQLite and feed that from another machine with the updated index. But it's so much more convenient to use App::cpanminus instead ...	[reply] [d/l]

I remember having tried cpanm but I had issues. I may try again, but my understanding is that the missing EXTERN.h will not be fixed by getting a cpan-client to work. This does not come with a module but should part of the perl-installation (or am I wrong?).	[reply]

Re: Out of memory! Killed What's the RAM on that thing? (not flash). You can use: `free` and `cat /proc/meminfo` I am totally ignorant of these devices but my common sense says that if indeed this is a problem of running out of memory, you either install more RAM or make swap-space from disk space, including an inserted USB or other flash memories. If you want help with that let me know. You can check your disk-space (flash/hard disk/usb) like: `df -h` bw, bliako	[reply] [d/l] [select]

If it's the same device as last time upgrading RAM is non trivial, if at all possible. For swap see Tutorials -> Embedded Perl: Installing Perl and Mojolicious on Arduino Yún / OpenWRT ChaosCalmer. Simply avoiding using something as memory hungry as cpan is likely a simpler move.	[reply]

It is the same device and upgrading it is not an option. I had hoped that there was some way to get Net::SSLeay on there, but I am about to give up. But even if I can get a less memory-hungry cpan-client to work it won't solve my problem with the missing EXTERN.h... But thanks anyway.	[reply]
