If gcc is a C/C++ compiler, what was it written in?

I'm going to take a stab at this one and say C and assembly.

If you're really curious you could download the source and read it.

I suspect that a really simple C compiler was made in assembly, then a more advanced compiler was compiler in that, etc etc, until the gcc we know.

I'm running LFS. One of the thing you have to do during the install is installing gcc, from source. Trust me, it has been written in C and probebly some assambler.

This is better than the chicken and egg question. schatoor, exactly how is gcc installed from source in LFS? What command does that?

I would say its written in C and comes along with some kind of assembler...or maybe its a bunch of embedded compilers with an assembler at the end.

When building LFS, your actually using an existing distro while compiling the base binaries...so when you compile gcc for your LFS, you compile it using gcc from the base distro.

Yes Grim Reaper is right. You have to alraidy have an installed linux system in order to install LFS. You build the gcc for LFS with the gcc alraidy installed on the host system.
A bit off topic, but I managed to install LFS without a linux alraidy on my HD. Just used knoppix straight from cd.

Killer idea!!! Use Knoppix!

I always wondering what a CD linux version could be useful for.
