Motif w/XRT vs QT or GTK+ on SPARC Solaris
 

I have a work project that has me stuck in the 1990s. I have been using Solaris 2.6 and trying to get to Solaris 10. Not easy! I managed to get the software project to recompile on S2.6 and partially on S10. Oracle says Motif is deprecated and I should move to GTK+. Easier said than done. I know nothing about GTK+ and not much more Motif. I am forced to use Visual Workshop 2 for the GUI. Damn, is this primitive!

I can compile new drivers (shared object libraries) in VWS2/S2.6, but a lot of the GUI stuff won't compile on VWS2/S10.

Maybe I'm over-complicating this. I hope to get to something modern like S10 or Linux and the Motif is a definite problem area. My project uses F77/C/C++ and GUI is Motif with XRT tables. The hope is to upgrade to Linux on an X86 platform. Currently on a Sun Ultra60/80.

Best way to proceed? Does Red Hat do this type of thing? Who knows Motif AND GTK+ (or QT)? What to use for a development environment? I have my hands full writing new drivers to replace old hardware.

Maybe someone out there has been thru something similar. I can only hope.

I can't give you full answer but this reminded me that back in 2007 I'd had an issue with Oracle requiring "Motif" and the Fedora system I was installing at the time didn't have that in repositories. Instead it had "lesstif" and on installing that it provided what was needed for Oracle (EBIZ R12) to run.

On checking I do see mention of lesstif for Solaris (unfortunately it only mentions 2.6) at the site below. It does however, mention a couple of patches done to make it work on Solaris that might give you some ideas.

I haven't done anything with lesstif on Solaris but on Fedora it simply worked in place of what Oracle was expecting from Motif.
