perl: Your Makefile has been rebuilt for several perl packages

Package Name

perl

Maintainer

Marcel Denia naoir@gmx.net, @pprindeville

OpenWrt Version

SNAPSHOT

OpenWrt Target/Subtarget

x86/64

Steps to Reproduce

1. Enable perl in make menuconfig
2. Compile OpenWrt with make -j9 V=s
3. Notice it will failed at several perl packages

Actual Behaviour

several perl packages will failed to compile with the following error :

Generating a Unix-style Makefile
Writing Makefile for Device::SerialPort
Writing MYMETA.yml and MYMETA.json

You're ready to run 'make' now...
==> Your Makefile has been rebuilt. <==
==> Please rerun the make command.  <==
false
make[4]: *** [Makefile:1017: Makefile] Error 1
make[4]: Leaving directory '/home/nameless/works/openwrt/build_dir/target-x86_64_glibc_nameless/perl/Device-SerialPort-1.04'
make[3]: *** [Makefile:70: /home/nameless/works/openwrt/build_dir/target-x86_64_glibc_nameless/perl/Device-SerialPort-1.04/.built] Error 2

What a weird thing is if I am compiling manually the failed perl package it will succeed, for example with command :

make package/perl-device-serialport/{clean,compile} -j9 V=s

@jw2013 , would you please take a look at this report.

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start with package/perl-device-serialport and reproduce the failure using make menuconfig followed by make -j9 V=s. Compare the full OpenWrt build with make package/perl-device-serialport/{clean,compile} -j9 V=s, focusing on the generated Makefile and the reported Device::SerialPort output. Done means the affected Perl packages compile successfully in the full build.
