Not to go off on a tangent, but... I am curious about your statement that gcc3.4.x will not compile kernel 2.4.x properly or apps for it? The reason I am asking is we are currently trying to move to a new cross-compiler for MIPs and need to be able to support 2.4.18 as well as 2.6.x.

(remark #2 is a matter of choice, though. getandpatch should be able to download it) > I should still let the install-glibc-headers section in the crosstool.sh > run Glibc-headers and kernel-headers are complementary, so yes you should leave it in. However there is a parallel discussion going on here about whether we need that separate glibc-headers step. Apparently in some cases it is possible to build a core-gcc without the glibc-headers. >when it finishes I should have a toolchain with the following > binutils 2.15.96 > glibc 2.3.4 > gcc 3.4.3 > > I can then use this toolchain to build a 2.6.11.6 kernel for my target Short answer: yes Long answer: Any 2.6.x kernel really. If you would have used gcc-3.3.x you could also have built a linux-2.4.x kernel with the same toolchain. Building the kernel is not the greatest issue. But (and please someone correct me if I'm wrong) the programs you compile with this toolchain will not run under a 2.4 kernel. The libc version and kernel headers version mainly affect on what system(s) your programs will run, not what you can or cannot compile with it.
