The gcc-TARGET dir is no longer used. template-gcc.tgz is instead built from a slightly modified version of the gcc source package. This has to be done manually before building the toolchain-source package as Build-Depends on source packages are nto possible. Check out the attached update_gcc.sh script. It is used to create template-gcc.tgz before the build. There is probably some pre 4.0 version of it in the source package. Note that a 4.0 template created this way don't work out of the box, some debugging and tweking is needed :) > > *) I've found multiple gcc-TARGET directories (./gcc-TARGET, and > ./t/gcc-TARGET); which one is the right one?

Well, the toolchain-source contains all those source codes, and they should be upgraded when newer versions is availible. There is a update.sh script that once did this. It might still work for binutils and gdb if you comment out the gcc stuff. But you don't have to update them att at once. Its probably better to take them one at the time until you get the hang of things. Maybe a good idea to start with upgrade the binutils or gdb sources, that should be quite straight forward, then move on to upgrading gcc, requires some tweeking and a lot of testting of for different targets. Check out test.sh it generates a set of corsscompilers, installs them and tries to compile some simple programs. newlib-support is not as important, but a nice feature once you get the rest working. > > I appreciate your help and understanding in that I might stumble in > the beginning...
