What exactly was the error you got? What was the make output leading up to the error? Thinking about this a bit, I think the problem you ran into here is that the instructions given on the web site are for building a kernel only compiler. This is not a compiler that you can use for building applications, as there is no glibc. This is also not a compiler that you can use for building gcc libraries. So the problem here is that gcc-4.x contains more libraries than gcc-3.x, including some written in C. The instructions say to use --enable-languages=c when configuring, and then type make all. This will work in gcc-3.x as there are no libraries for the C front end. This will not work for gcc-4.x, as there is at least one library for the C front end, namely mudflap. So I am guessing you got the error while configuring libmudflap. The solution is to use "make all-gcc" instead of "make all" when building gcc. This will build only the compiler (and libgcc), without any of the target libraries, that are unneeded for a kernel compiler. If this works, perhaps the instructions on the wiki should be changed. Using "make all-gcc" should work for all gcc versions. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
