Hi all!
akosv:/home/akos# gcc --version
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

I am using the next source packages to build a cross-toolchain for arm-linux:
binutils-2.17
gcc-4.0.2
linux-2.6.21.
uclibc-0.9.29
I have successfully built the binutils package with the commands:
TARGET=arm-linux
PREFIX=/home/akos/ARM/tools
akos@akosv:~/ARM/build-tools/build/gcc$ ../../binutils-2.17/configure --target=${TARGET} --prefix=${PREFIX}
akos@akosv:~/ARM/build-tools/build/gcc$ make
akos@akosv:~/ARM/build-tools/build/gcc$ make install
Everything works fine, they build, they install
Next, I try to compile a bootstrap-compiler with which I can compile the uClibc library, and the final compiler afterwards.
I have read a lot of howtos regarding how to do this, but none of them worked for me... maybe i am missing something, i don't know.
Anyhow, as far as I understand, I should be able to build gcc without *any* libraries, and afterwards I can use that minimalist compiler to build a library for itself, and then build a full compiler.
When I try building the bootstrap compiler, it fails:
I don't know how to interpret the warning that autoconf issues, but I think it can be ignored... Please correct me if I'm wrong
Oh, and pls tell me what this libmudflap is... I have read it must be disabled, but it doesn't say what it is

There are a few things I don't really understand:
1. what is it doing in libgcc? Didn't I just tell him *not* to use any libraries?
2. why is it linking to crti.o?
3. why doesn't it work? :D:P
Thanks in advance for your kind help,
Akos Vandra
