Hi,
I am new to building deb packages, and I would like some help with a
question.
I am trying to build a deb package for Milvus(https://milvus.io/) on Ubuntu18.04 or Ubuntu 20.04. Building Milvus requires Cmake 3.18 or higher,
but the latest version of cmake is 3.16 on Ubuntu 20.04 (golang has the
same situation). Could I directly use the cmake binary when building my package? Or is there any other solution?

Kind regards,
Yunmei LI

For official packages the only common option would be to not build it on systems where the required dependency versions are not available.

I don't understand what the "directly use the cmake binary" means.
When cmake is needed, have cmake in the build environment ...

Or is there any other solution?

And I don't understand the problem :-/

Is the problem

Upstream saying "cmake 3.18 meter long works for us" and
Yunmei asking "Will cmake of size 3.16 meter be long enough?"

or

Upstream saying "We us features from cmake that first appeared in 3.18"
and Yunmei reporting "I did one attempt and got some build error"

?

There is no need for alienating people that have a question
about building .debs

In http://www.catb.org/~esr/faqs/smart-questions.html is documented
that it is OK to ignore questions that don't deserve your time.

Show the world that you understand
that this is the mailinglinglist debian-mentors@lists.debian.org

For official packages the only common option would be to not build it on systems where the required dependency versions are not available.

Do not tell it can't be done to people who are already doing it.

Hi,

[...] Could I directly use the cmake binary when building my
package?

I don't understand what the "directly use the cmake binary" means.
When cmake is needed, have cmake in the build environment ...

I think this might refer to CMake directly being able to build .deb
packages (see https://cmake.org/cmake/help/latest/cpack_gen/deb.html)
without going through a source package?
This might work for personal use but would not be OK for inclusion into
the 'official' Debian archive.

Cheers
Sascha

I think the OP meant manually putting a cmake 3.18 binary in the search
path of the system that doesnt have that version packaged, totally
missing the fact that automated building exists.

As others have already replied, for your local packages you are
completely free to do just anything, really. However, if you want
others, the automated builders of the release in particular, to rebuild
your package then this is not helpful.

If you are stuck with these older versions of Ubuntu then you could
backport cmake 3.18 to these releases. How exactly this works in Ubuntu
I cannot tell. You may want to start here https://help.ubuntu.com/community/UbuntuBackports

Best,
Steffen
