icon.xpm is no longer readable in Fedora

[myk321]

Describe the bug
Referencing the icon in a gnome .desktop file but no icon is displayed in gnome shell.
Gimp and gnome image view cannot open icon.xpm.

Gimp gives the following error message:

Plug-in crashed: "file-xpm"
(/app/lib64/gimp/3.0/plug-ins/file-xpm/file-xpm)
The dying plug-in may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.

Opening '/home/myk/eclipseCDT/icon.xpm' failed:
Procedure 'file-xpm-load' returned no return values

Image Viewer gives the following error message:

Unknown image format: image/x-xpixmap

**To Reproduce**
Using Fedora Linux 43 (Desktop)
Download eclipse CDT from: https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2025-09/R/eclipse-embedcpp-2025-09-R-linux-gtk-x86_64.tar.gz
Unpack
Try and open the icon.xpm file in either Image Viewer or Gnome
Try and reference the icon.xpm in a Desktop file

**Expected behavior**
icon.xpm is replaced with a .png or ,svg icon
Gimp and Gnome Image Viewer can open and display  icon
Gnome shell can open and display icon.xpm

If this is a problem for EPP, I expect it's a problem for all projects to do branding, a problem for the Eclipse SDK itself:

What should be used instead?

[akurtakov]

PNG is the best but I am not sure that all the bits to use PNG icons are there, as in I gave it quick try to just replace with png when it first appeared (eclipse-platform/eclipse.platform.swt#1307 (comment)) but it didn't work from first try and I don't remember what the problem was.

The workaround is to install gdk-pixbuf2-modules-extra and many(majority of?) users end up with it installed as a dependency for other packages .

[jonahgraham]

If this is a problem for EPP, I expect it's a problem for all projects to do branding, a problem for the Eclipse SDK itself:

Yes, I agree. The EPP will follow what Platform does here. This issue eclipse-platform/eclipse.platform#1756 was a previous discussion on this in platform.

[jonahgraham]

The workaround is to install gdk-pixbuf2-modules-extra and many(majority of?) users end up with it installed as a dependency for other packages .

Can we automate/detect this until eclipse-platform/eclipse.platform#1756 is solved? Is there any other case in Eclipse that warns/errors/pop-ups/etc on missing native libraries we can use as a starting point?

[akurtakov]

@jonahgraham I have been thinking of smth like https://github.com/eclipse-linuxtools/org.eclipse.linuxtools/blob/b3bc9d9fed7c64a31bc699c9546a98c6f7e9d77c/systemtap/org.eclipse.linuxtools.systemtap.ui.ide/META-INF/p2.inf#L2 but it's not viable on startup.
