[Mercotui]

I see the recipe requires conan >=1.64.0 <2 || >=2.2.0, but is that really a sane requirement?

I see fedora 40 will even ship with conan 2.1.0, how many users are running the absolute latest version of this tool?

[jwillikers]

Thanks for reporting! Holdup, Fedora is shipping Conan?! Wow, I had no idea!

Unfortunately, that requirement was bumped to accommodate a functional change in Conan 1.64.0 and Conan 2.2.0, which was necessary for #23500. The Meson generator switched from needing absolute paths to using relative paths for xxxdir variables. It might be possible for me change the paths are set based on the Conan version to support older Conan versions. Otherwise, you'd have to pin a revision but that would be bad in this situation since that is an important fix. @franramirez688 Would you have any input on this?

[jwillikers]

I'm surprised that your pulling in libglvnd since my PR's to switch glew and glfw over to that haven't been merged yet.

[Mercotui]

Profile pic checks out, yeah fedora ships conan 😅

Thanks for the quick response,
If it helps at all, it seems this happens when I require glew/2.2.0:

And a small note that I am not very invested in getting this working on my system, I was only installing this package to compile some example code, which I managed by installing the dependencies via yum 😬

[franramirez688]

Hi @Mercotui - Thanks for reporting it! And thanks for the ping @jwillikers 😁

I see the recipe requires conan >=1.64.0 <2 || >=2.2.0, but is that really a sane requirement?

What do you mean by a sane requirement? Let me understand your situation. Is there any problem with updating your current Conan version? MesonToolchain introduced an important change in Conan 1.64 and Conan 2.2.0 so I recommend using the most recent one if it's possible, Conan 2.2.3. Conan 2.x is continuously evolving and getting more and more robust so that's why I recommend that.

I'm surprised that your pulling in libglvnd since my PR's to switch glew and glfw over to that haven't been merged yet.

I saw that it's updating mesa-glu/9.0.3, which the latest revision is requiringlibglvnd.

[Mercotui]

Hey,
With "sane" I meant that the conan version I use is 2 months old, and I am surprised that it is not supported by these packages. I thought this might have been an error or oversight.

As far as updating my conan.. I used the version my OS packages,
so to upgrade in this case means to install it via a different path.

Updating conan is possible, but for me it is more work than not using conan.
I was 5 minutes into my project with conan, and instead I decided to use yum to install my dependencies.

I found I don't need glew or glfw at this point in time, so I'll try to continue to use conan 2.1.0 unless I run into similar issues with packages that I do want.

[Mercotui]

I ran into this conan version issue again, this time with wayland/1.22.0, and I really want the package.

So I did the following:

sudo yum remove conan
sudo yum install pipx
pipx install conan

Which I guess is a good compromise for me.
I hope this gives me the latest version of conan,
without having to deal with python dependency pain.

[franramirez688]

@Mercotui did you have any problem installing the latest one?
If not, I think that we could close this ticket as solved.

[Mercotui]

Sure I'll close the ticket as resolved,
I am satisfied with my current setup.

Thanks for sharing your insight 👍
