Ungrib build fails when jasper version > 3.

Also there is similar problem with NCEPLIBS;

Which compiler was used ?

[bakamotokatas]

hello @andrewsoong, I used GCC and gfortran version 12.1.1

[andrewsoong]

@bakamotokatas I am using Intel Compilers(V2018.1.48), It can compiled WPS v4.4 succussfully, but the geogrid.exe could not run.
The WPS v4.3.1 is OK.

[bakamotokatas]

@andrewsoong We're talking about other issues, I'm talking about a WPS compilation issue with the new jasper version. I can compile WPS with old jasper versions, jasper 1.900.1 or version 2 variants. There is a problem with compiling with the newly released jasper version 3. I just wrote to report a problem.

[WillTrojak]

I recently encountered this issue and the fix was to change the jpc_decode and jpc_encode functions over to jas_image_decode and jas_image_encode. It seems that the former were undocumented internal functions of Jasper which have now been removed. You have to make an additional call to jas_image_getfmt to get the fmt int.

[WillTrojak]

Is there any plan to fix this issue in a future release? The fix I made seems to work fine, I could make a PR if you like.

[weiwangncar]

@WillTrojak Does your problem also exist with --build-grib2-libs compile option? This option builds the jasper and other required grib 2 libraries at the WPS compile time.

[mgduda]

@WillTrojak If your changes work with older Jasper library versions (e.g., 1.900.X) and if they work when using the option that @weiwangncar mentioned to build an embedded copy of the Jasper library, then we'd be glad to receive a PR with your fixes. If you have any questions about the PR process, please don't hesitate to let me know and I'll be glad to help!

I am getting this issue. I tried with the latest jasper 4.2.5 and then 1.900.1
It did not work

Is there any plan to fix this issue in a future release? The fix I made seems to work fine, I could make a PR if you like.

@WillTrojak : Could you provide more details on how you fixed this? This issue doesn't seem to have been resolved.
Thanks.

[WillTrojak]

Hi, this was some time ago and I can't find the patch I made before. But the issue was a small change in the function names used. So I think all you need to do is grep for the undefined functions above and replace them with the new function names.

I don't have a WRF install anymore, so I wouldn't feel comfortable making the fix. But happy to review a PR.

[agungbaruna]

I tried change the function as @WillTrojak said on Apr 6, 2023. It was tested and worked on my machine by using oneAPI Intel Compilers. I use jasper 4.2.8 version for compiling the newest version of WPS.
