Yes I can, and no you probably don't. Actually, my Solaris 2.5 systems have TWO libraries in this directory: XIL and XGL. XIL is, as you noticed, an image library, with code for JPEG, MPEG, and so forth. Sun's imagetool program uses this library to decode JPEG's, but it is SO slow on my 486, I just use XV. The only third-party program I've used which uses XIL is the vic program for video-conferencing on the MBONE (and that came in two versions, one for XIL and one without). XGL is Sun's answer to OpenGL, in other words a library for 3-D acceleration. A few programs, like AutoCAD use it, but it never really caught on. That's why Sun is now selling the real OpenGL for UltraSPARCs with Creator Graphics. In other words, for your SPARC 1+, you most likely don't have a need for either product. Pkginfo will show you which packages are installed: > pkginfo | grep -i xil application SUNWxildg XIL Loadable Pipeline Libraries application SUNWxiler XIL English Localization application SUNWxilh XIL Header Files application SUNWxilow XIL Deskset Loadable Pipeline Libraries application SUNWxilrt XIL Runtime Environment application SUNWxipsr XIL Platform Specific Device Pipeline Libraries (/opt) application SUNWxipsu XIL Platform Specific Device Pipeline Libraries (/usr) > pkginfo | grep -i xgl application SUNWxgldg XGL Generic Loadable Libraries application SUNWxgler XGL English Localization application SUNWxglft XGL Stroke Fonts application SUNWxglh XGL Include Files application SUNWxglps XGL Platform Specific Device Pipeline Libraries application SUNWxglrt XGL Runtime Environment And you can use pkgrm to remove them. NOte that I haven't tried this, and there might be a few of those packages that are required for OpenWindows, but the package mechanism should tell you if you remove them in the wrong order. Just write down the names, and if you ever need them later, you can add them back from the Solaris CD-ROM. Cheers, -- Jake
