[Buildroot] [PATCH] package/libxml-parser-perl: add host-libxcrypt dependency

[Buildroot] [PATCH] package/libxml-parser-perl: add host-libxcrypt dependency

[Adam Ford]

host-libxml-parser-perl compiles XS modules against the system perl
headers, which #include <crypt.h>. On build hosts without libcrypt-dev
installed, the build fails:

    .../CORE/reentr.h:126:16: fatal error: crypt.h: No such file or directory

Declaring host-libxcrypt ensures crypt.h is present in the per-package
host sysroot before the build.

Gentle nudge on this.

Sorry for the delay in getting back to you. Could you provide some
details on the environment/distribution where crypt.h is not available
on the host? I've tried but on Fedora or Ubuntu, as soon as
glibc-devel (or equivalent) is installed, it pulls in
libxcrypt-devel. On Archlinux, /usr/include/crypt.h is also present.

Thanks for the additional information that you'll provide on this
topic!

Best regards,

Thomas

Not the author but in Debian Forky (testing) and Sid, libc6-dev no 
longer depends on libcrypt-dev, the provider of crypt.h.  libcrypt-dev 
now only have these reverse dependencies:

gauche-dev, guile-3.0-dev, heimdal-multidev, libapr1-dev, 
libidzebra-2.0-dev, libperl-dev, libuser1-dev, sa-compile

None of which would be typically present on a developer or builder system.

Thanks for this additional information! With this, I was able to
reproduce the build issue, so I applied the patch to our master
branch.

Thanks a lot!
