Syslinux - Apr 2022 - Fail to build debian package syslinux-common

Hi


First of all here is my setup : Debian 10.12 through VirtualBox 6.0.
For some reasons, I have to build the debian package
"syslinux-common". I did the following steps :

apt-get source syslinux-common
cd syslinux-6.04~git20190206.bf6db5b4+dfsg1
apt build-dep syslinux-common
debuild -b -us -ui -uc

This process fails with the following error happening in the dh_missing process
:

dh_missing --fail-missing
dh_missing: usr/share/syslinux/syslinux.exe exists in debian/tmp but is not
installed to anywhere
dh_missing: usr/share/syslinux/syslinux64.exe exists in debian/tmp but is not
installed to anywhere
dh_missing: missing files, aborting
	The following debhelper tools have reported what they installed (with files per
package)
	 * dh_install: extlinux (5), isolinux (10), pxelinux (3), syslinux (5),
syslinux-common (166), syslinux-efi (2), syslinux-utils (11)
	 * dh_installdocs: extlinux (0), isolinux (0), pxelinux (0), syslinux (0),
syslinux-common (0), syslinux-efi (0), syslinux-utils (0)
	 * dh_installexamples: extlinux (0), isolinux (0), pxelinux (0), syslinux (0),
syslinux-common (5), syslinux-efi (0), syslinux-utils (0)
	 * dh_installman: extlinux (1), isolinux (0), pxelinux (0), syslinux (1),
syslinux-common (0), syslinux-efi (0), syslinux-utils (11)
	If the missing files are installed by another tool, please file a bug against
it.
	When filing the report, if the tool is not part of debhelper itself, please
reference the
	"Logging helpers and dh_missing" section from the
"PROGRAMMING" guide for debhelper (10.6.3+).
	  (in the debhelper package: /usr/share/doc/debhelper/PROGRAMMING.gz)
	Be sure to test with dpkg-buildpackage -A/-B as the results may vary when only
a subset is built
	For a short-term work-around: Add the files to debian/not-installed

It complains about exe file not installed on the system, I tried to build only
the architecture independent binary packages (-A option),
 resulting with the same error. Architecture specific binary packages only (-B
option) fails also with the same error.

I wonder why debuild complains about exe files not installed and how to fix it.

Thanks

Hi Pierre,

sorry for not responding sooner.  I'm not looking at this mailing list
regularly and only just now saw your mail.

You should be able to build the package by modifying the file
`debian/not-installed` before running `debuild ?` and adding the
following line to it:

usr/share/syslinux/*.exe


Some context of why this is happening: Debian's tools fail the build as
a safety check if there are files that the syslinux build system would
like to install but they are not put in any Debian package.

In your case:  Since we don't need the Windows executables we can add
the entry entry above to let Debian's tools know we're fine with not
installing them.  I assume this is happening to you because you have
all the necessary tools to build Windows executables installed on your
system.  Thus the syslinux build system builds them by default and we
need to tell Debian's tools to ignore them.

I consider this a bug in the src:syslinux Debian package, so feel free
to file one.  In any case I'll include the change mentioned above in a
future Debian upload.

In general, if you encounter build problems with a Debian package, I'd
recommend using Debian's bugtracker since that should reach the persons
responsible for maintaining the Debian builds specifically.
