These config.sh.* files are generated during the package build
|
|
and installed into the libperl5.xx package, in the directory
|
|
/usr/lib/<triplet>/perl/config-data-<version>. They contain probed values
|
|
about system configuration, used for cross building the package.
|
|
|
|
The probes currently need to run on the native architecture, so they
|
|
cannot be used for cross building. As a workaround, we store the results
|
|
in the built binary package and then manually copy them back to the
|
|
source package as needed.
|
|
|
|
The process is currently experimental, and no commitment is made on long
|
|
term feasibility of this. We will see how it goes.
|
|

There is some tooling to help the process of incorporating the generated
|
|
config.sh.* files from architecture specific binary packages back into
|
|
the source package:
|
|
|
|
- debian/cross/download-deb can be used to pull in the required binary package
|
|
|
|
- debian/cross/extract-config-sh can then be run on the downloaded
|
|
package(s) to copy the config.sh.* files into the source tree and commit
|
|
the changes into the git repository.
|
|
|
|
An example transcript would be:
|
|
|
|
$ for arch in amd64 arm64 armel armhf i386 mips64el mipsel ppc64el s390x; do ./debian/cross/download-deb -p libperl5.32 -v 5.32.1-2 -s 'deb http://deb.debian.org/debian unstable main' $arch; done
|
|
$ for arch in alpha hppa hurd-i386 ia64 kfreebsd-amd64 kfreebsd-i386 m68k powerpc ppc64 riscv64 sh4 sparc64 x32; do ./debian/cross/download-deb -p libperl5.32 -v 5.32.1-2 -s 'deb http://deb.debian.org/debian-ports unstable main' $arch; done
|
|
$ ./debian/cross/extract-config-sh libperl*.deb
|
|
|
|
The debian-ports part needs the debian-ports-archive-keyring package installed
|
|
(but could be done in an ephemeral chroot if that seems preferrable.)
|
|
|
|
As always, this is still work in progress and will hopefully improve over time.
