Yes, my research came up with the -mxgot option also. Tried that and came up with a problem where the elf2flt doesn't like the larger GOT format. Aparently it's a problem my client has been fighting with for a long time and I was able to define out a log statement and that killed enough strings (5,000 log strings!) in the project to get it to build. Basically I was told: "Get it to build and we'll deal with the problem over here." Done. -Os helped some also, but not with the GOT issue. But size-wise it helped. Upgrading to Linux 3.2 from 2.4 (and the other apps) has increased our total image size by nearly 50% and we're starting to bump into size issues. I'm having to kill off some useful technician and debugging utilities now. Thanks for the help. - Steve _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
