labplot does not find eigen3

Help
1

Hello,

I have labplot2.12 installed on mageia linux

uname -a
Linux Octopus 6.18.30-desktop-2.mga10 #1 SMP PREEMPT_DYNAMIC Fri May 15 12:19:15 UTC 2026 x86_64 GNU/Linux

In About/Components Eigen3 is listed as missing. I have just installed eigen 5:

(base) [fernando@Octopus ~]$ rpm -qa | grep -i eigen
mingw64-eigen3-3.4.0-1.mga10
eigen3-devel-5.0.1-1.mga10
eigen3-doc-5.0.1-1.mga10

But after restart labplot still lists Eigen3 as missing.

What can I do?

Best regards

installing the library alone won’t be enough, it has to be available together with its devel package during the build process. If you compiled labplot from the source on your own, just install eigen3-devel and recompile again. If you installed the package provided by your distribution, it’s better to report it upstream so they can build with eigen. Note, it’s an optional dependency.
