This is a bug report for perl from Niko Tyni <ntyni@debian.org>, generated with the help of perlbug 1.40 running under perl 5.22.1. ----------------------------------------------------------------- Commit 97076f2 added a graceful exit to Configure when targethost is not defined but usecrosscompile is. However, this is not reached because there is a similar check a bit earlier that makes Configure bail out. The attached patch makes the earlier check warn instead of croaking. The use case for this combination is supplying an external config.sh suitable for the target platform, avoiding the need for configuration probes. ----------------------------------------------------------------- --- Flags: category=core severity=low Type=Patch PatchStatus=HasPatch --- Site configuration information for perl 5.22.1: Configured by Debian Project at Sat Dec 26 07:28:43 UTC 2015.

I looked this over and tested with and without the patch and it makes sense. I've applied the patch as 23695c073f41fdac9d20d873827ba8b2a3dda7102. I noted it in perldelta as: C<Configure> now builds C<miniperl> and C<generate_uudmap> if you invoke it with C<-Dusecrosscompiler> but not C<-Dtargethost=somehost>. This means you can supply your target platform C<config.sh>, generate the headers and proceed to build your cross-target perl. [perl #127234] Tony
