Bug ID: 12806
Summary: There are multiple issues in buildroot that faults
cups printing
Product: buildroot
Version: 2020.02.1
Hardware: PC
OS: Linux
Status: NEW
Severity: critical
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: skif at skif-web.ru
CC: buildroot at uclibc.org
Target Milestone: ---

First trouble is incorrect qpdf buiding.
Qpdf is mandatory dependence of cups.
In current master, qpdf builds with incorrect --no-random option. On
any work< qpdf send 'no such file' error. For example:
qpdf /usr/share/cups/data/secret.pdf -

This commmand must get PDF file in stdout.But only 'No such file or
directory' error present.

0/1 patch fix this by changing configure options to
with-random=/dev/random.

Next global problem - cups-filters need ghostscript.
From https://github.com/OpenPrinting/cups-filters/blob/master/README :
By default, pdftops uses Ghostscript if this does not get changed
at compile time, for example by the Linux distribution vendor.

0/2 patch fix id by settinbg ghostscript as default render if
ghostscript enabled in voard config.

Last trouble - ghostscript building without cups support.

0/3 patch fix is by removing disable-patch option. Now, if cups is
enabled, it will be added to dependencies and correct configure
options added to ghostscript building. Also fixed ghostscript
buildroot building issue with unpleasant hack in configure.ac, which
broke pkg-config. It's broke cups search by ghostscript configure
script.
GHOSTSCRIPT_CUPS_CONFIG_FIX also needed for this task.
