scilab

[Patrick Dupre]

Hello,

Trying to run scilab under fedora34
'/usr/local/scilab-6.1.0/bin/scilab) from the files available on the scilab
web site, I get
Gtk-Message: 15:06:56.350: Failed to load module "pk-gtk-module"

dnf repoquery --whatprovides  'pk-gtk-module'
does not provide any information

rpmfind provides
PackageKit-gtk3-module
(/usr/lib64/gnome-settings-daemon-3.0/gtk-modules/pk-gtk-module.desktop
/usr/lib64/gtk-3.0/modules/libpk-gtk-module.so)

Package PackageKit-gtk3-module-1.2.3-1.fc34.x86_64 is already installed

I am not sure about what I should do

That sounds like /usr/lib64/gtk-3.0/modules/libpk-gtk-module.so is not 
in LD_LIBRARY_PATH.

Add it on the command line and run scilab from command line with it 
added.  Let's see if that resolves the issue.

Or else the application included its own copy that isn't linking to 
something else.

but still

If you are building your own software outside of standard paths, you’ll either need to link with —rpath or set up your own LD_LIBRARY_PATH for wherever you installed your scilab libraries.  Probably the same path as the executables, only in …/lib.  This is a general Linux issue, not really a “Fedora” issue, per se.

I use Lmod for environment modules for stuff like this, if I’m not packaging the software.

Now, as a regular user, I get:
