[GRASS-user] i.svm.* modules and manuals missing in GRASS 8.4 and online

Hi all,

I want to try the new i.svm.* modules, but I discovered the manuals are not online at https://grass.osgeo.org/grass84/manuals/full_index.html#i and the modules are grey in the GUI. I installed the libsvm-dev package and added --with-SVM to the conf instruction, but that didn’t work. I searched around but neither the wiki nor the html manual files have any hint about compilation with svm support. How should I specify the conf instruction?

Maybe GRASS main is not being compiled with svm support in the server and that is why manuals do not appear online?

Thanks in advance!

found it in the configure file in the source code: --with-libsvm

I can add it to the server compilation. But which library is needed?
It is missing from
grep -i svm REQUIREMENTS.md

?

thanks,

The library is LIBSVM, for Ubuntu it was libsvm-dev

Ok, in Fedora:
dnf install libsvm-devel

Please someone may open a pul request (PR) to update REQUIREMENTS.md
accordingly.
