GLIBC problem is back... [CentOS 7 RIP]

[treble]

Using SeaDAS 8.4.1 with the latest tag (V2023.3) gives me the GLIBC error again on CentOS 7. See this old discussion: viewtopic.php?t=1419

V2023.2 still works fine...:

Code: Select all

[/opt/seadas/seadas_8.4.1/ocssw 1016]$ install_ocssw --installed_tag

WARNING: --tag is required to get the proper bundle list.

installedTag = V2023.2
[/opt/seadas/seadas_8.4.1/ocssw 1017]$ l2gen -version
msl12 9.6.0-V2023.1 (Apr  4 2023 11:30:59)

This is the output with V2023.3:

I tried to compile from source code but was not successful...

CentOS7 is end of life in June. We no longer have (or are allowed to have) a CentOS7 machine, the "oldest" we have is RHEL8 (which is what V2023.3 was compiled on). Since it still works for you, you can continue to use V2023.2 or look to upgrade your server to an OS with a longer support cycle.

Ah, that is unfortunate. Especially since the high performance computer cluster at our university is running CentOS 7 as well...

I will have to build from source in the future then I am afraid. I tried it now as well (following the directions for CentOS on the website) but it failed at compiling hdf4 with a not so descriptive error:

Code: Select all

Working on hdf4
Extracting hdf-4.2.16.tar.gz
patching file hdf/src/hlimits.h
Unknown error encountered installing hdf4

[OB.DAAC - SeanBailey]

CentOS7 had a good run.

The error message you saw was from the wrapper "BuildIt.py" script. You can build the hdf4 by itself and see what the actually complaint (navigate to opt/src/hdf4 and run it's BuildIt script). It is likely resolvable (but without access to a CentOS7 machine, I'm afraid we can't be of much help here...)

Thanks, it fails on linking the jpeg libraries. See last pertinent part where it fails below. Earlier on I see that it doesn't use the compiled jpeg libraries but the system ones... Not sure how to tell cmake or whatever to use the one in the SeaDAS directory (it is located in $OCSSWROOT/opt/lib/libjpeg.so, I don't see libz.so in $OCSSWROOT):

Code: Select all

-- ....All Warnings are enabled
-- Could NOT find JPEG (missing: JPEG_DIR)
-- Found JPEG: /share/software/user/open/java/1.8.0_131/jre/lib/amd64/libjpeg.so (found version "90") 
-- JPEGLIB is ON
-- Could NOT find ZLIB (missing: ZLIB_DIR)
-- Found ZLIB: /share/software/user/open/zlib/1.2.11/lib/libz.so (found version "1.2.11") 

Here is the error and what leads up to it:

It's not super urgent, but it would be nice if I got it to compile.
