Please note that "derives from" does not mean "is compatible with". > Trouble is, if I 'ppc-rpm' an YDL package, > I get an architecture mismatch (which is > not surprising, all ELDK packages being > 'ppc_8xx' while YDL packages are 'ppc'). This is an indication of RPMs being not compatible. You CANNOT use a "standard" PowerPC RPM and install it on a MPC8xx (ppc_8xx) system. If you try to do so you will just see that the tools will not work (crash and/or produce wrong results). One of the important differences is that the "standard" PowerPC distributions (like YD) assume that there is a hardware FPU on your CPU, which is not the case on the MPC8xx. This must be taken into account when building any library and application. You will have to use the source RPMs instead, and rebuild from the sources. See section "8.2. Rebuilding Target Packages" in the ELDK documentation. Note that in almost all cases you will have to make some adaptions to the RPM spec file.
