Only if you run into trouble with your old compiler. If and when you decide to rebuild the compiler, see http://kegel.com/crosstool for a recipe you can follow. > 2.

Again, http://kegel.com/crosstool (if you study it, and compare it with Karim's book) will help show you how to build the glibc of your choice. > 3.

That same URL can show how to build a reasonable toolchain for the ppc405 without any thought on your part, if you choose to not read and understand the script. It's always better to read and understand, though. > Sorry for the newbie type questions. I have the "Using and Porting GNU > CC" book, but am finding it a little too Stallman-esque to follow. Anyone? Your question is quite reasonable. BTW, which glibc does your toolchain use? - Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
