Glad to have been able to help a little bit.

cdi builds normally and make check works just fine

one CDI use case is CDO, which can use JPEG packaging. CDI is also used MPI-parallel simulation codes. I wanted to make sure it works as a standalone.

again: thx for pointing me to this. every software needs some extra care from time to time ;-)

Thanks for checking this. I did not look into eccodes, I only saw that this codebase does not link to openjpeg as far as I could tell.

Oh, sorry, I didn't see your latest comment. Everything works fine without openjpeg, I surmise?

MarsSeed commented on 2023-07-18 09:00 (UTC)

But we are not talking about JPEG at all.

We are talking about JPEG 2000, which, apart from its name, is completely unrelated to the former standard on the technical and implementation level.

Where do you see this code link to the legacy openjpeg1? Please show me, otherwise it's hard to believe on blind faith.

This program supports JPEG compression, without openjpeg, just fine.

Openjpeg does not support JPEG, only JPEG 2000. Which this application does not support.

Also it is already dubious that this program would add the legacy openjpeg1 as dependency in 2021 when at that time the openjpeg2 library was the maintained and stable release.

@MarsSeed

I could remove the extra dep to openjpeg 'cause eccodes does not need it anymore . seems linking against eccodes works a lot smoother now.

thx for pointing me to it! was a long time ago, when I set this up ...

hey! JPEG is not only an image format, but also a compression/packaging algorithm. It can be used by the eccodes (https://aur.archlinux.org/packages/eccodes) library to compress GRIB2, which needs extra linking flag for CDO in order to be used.

Hi,

I don't think this software supports the niche JPEG 2000 image format (via the legacy openjpeg or otherwise).

I only see JPEG support, which is totally different, and doesn't need openjpeg/openjpeg2.

Could you please check my assumption to verify or refute it? Thank you in advance.

openjpeg is added in cdi-1.9.9-2

This needs openjpeg as a dependency
