Error when running make #23

When you build ddcutil from source, "sudo make install" installs the
command line version of ddcutil, the shared library, and the development
files. For distribution, these pieces are split into packages ddcutil,
ddcutilN (where N is the shared library version number), and the
development files. It looks like you've installed only the first package.
The current version of ddcui requires ddcutil 0.9.9. So unless the Mint
packages are at that level, you'll need to build ddcutil from source.
Alternatively, you can get the latest prebuilt Ubuntu packages for
ddcutil (and ddcui as well) from the launchpad ppa
<https://launchpad.net/~rockowitz/+archive/ubuntu/ddcutil>
Note that if you build and install ddcutil from source, by default "sudo
make install" installs the include files and shared library under
/usr/local/, .e.g. /usr/local/include. Depending on your distribution,
these files may or may not be in the system include and shared library
paths, so some fixup may be required for ddcui to find them. For
further details, see the page Building ddcui
<http://www.ddcutil.com/building_ddcui> on the ddcutil web site.

Thank you for your quick reply. However, when I try to compile the source I get another error. Can you please do the following

Mint package had version |0.9.8-2|. I installed latest version of
|libddcutil-dev| and |ddcutil| from the PPA, and the compiled version
of |ddcui| in the PPA works.
Comments on ddcui are particularly welcome. It's far from ready for
prime time.
However, when I try to compile I get another issue.
Output: https://pastebin.com/SdEqbdyi
Looking at the output, the link command does not include "-l ddcutil"
and if necessary "-L/usr/local/lib". Look at the LIBS assignment at
around line 43 in the generated Makefile. It looks like pkgconfig is
not returning the correct information. (From the command line,
"pkg-config --libs", "pkg-config --cflags"). Where in the file system
is ddcutil.pc? If /usr/local/lib/pkgconfig, is that directory in the
pkgconfig search path?
Can you please do the following
1. Enable PPA packages for Ubuntu 20.10 (just copy the packages from
20.04)
Done.
1. Backport latest version of |ddcui| and |ddcutil| to Ubuntu 18.04
and 16.04 unless there are any missing runtime dependencies
(again, copy the packages without rebuilding)
Fails. From the emails: "same version already has published binaries in
the destination archive". Since I don't see the "published binaries"
it's not clear how get around this.
For future ddcutil/ddcui releases, I think the solution will be to
initially build for 16.04 (or later if necessary), then copy to later
Ubuntu releases.
1. Mention the PPA in the README of |ddcui| as well as the website.
The PPA is somewhat hard to find.
Good idea.

I will look into it.
As far as I can remember, selecting this option while copying packages solves this issue. No need to publish for 16.04 first. |

I tried copying rather than rebuilding for older Ubuntu releases, then
thought better of it. While I know of no reason the current ddcutil
should not work on earlier Ubuntu releases, to be certain packages
should be rebuilt, not just copied. Plus, ddcui is a newer program, and
its dependencies (Qt) are more complex. I'll revisit the build process
for the next release. Thanks for pointing out the problem.
