error in install ncl

[abdossamad2003]

hi centos export
I need a ncl package, but I encounter the following error during installation

Code: Select all

[samad@localhost Downloads]$ sudo yum install ncl.x86_64

Error: 
 Problem: package ncl-6.6.2-12.el8.x86_64 requires libgdal.so.26()(64bit), but none of the providers can be installed
  - conflicting requests
  - nothing provides libpoppler.so.78()(64bit) needed by gdal-libs-3.0.4-5.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

in centos 8, there is libpoppler.so.104()(64bit) and libpoppler.so.78()(64bit) is old

thanks

It comes from EPEL but it works for me. Make sure you have the appstream, powertools and possible epel-playground repos enabled as well as EPEL itself.

Where did you get that libpoppler.so.104()(64bit) from?

I'm going to guess Stream vs CentOS Linux 8. Mine is CL8...

[sml]

Yep, Trevor, you're right.

@OP. The package ncl is provided by EPEL 8. EPEL 8 packages are built on and for RHEL/CentOS Linux 8. They may or may not work with CentOS Stream 8. This package won't. At least, until the poppler version from Stream migrates to CentOS 8.4, and EPEL maintainers rebuild their packages against it. But by then, Stream may receive a yet newer version of poppler. Vicious circle.

[TrevorH]

soname changes are quite rare in RHEL and usually happen at point releases when they do. Since Stream is a moving beta, it gets this update before it goes into RHEL which would happen at 8.4 it seems. It's quite rare for things to get soname changes more than once in a while so hopefully it's safe once this has been handled. But until RHEL 8.4 comes out and EPEL update, this package will not work on Stream.

But RedHat assures us that changing from CentOS to Stream will have no noticeable effect!

[TrevorH]

Something that needs to be reported on the EPEL mailing list I think, perhaps with a suggestion that there should be an epel-stream repo configured to be prioritised before epel itself so that Stream specific updates can be published in advance.

Stream repo it is.

Poppler has changed into the year.month scheme?

But RedHat assures us that changing from CentOS to Stream will have no noticeable effect!

I don't think that their assurance can cover third party content, like EPEL.
