Linux From Scratch GCC Compile Error

[fatsheep]

Binutils compiled successfully but when I run the "make bootstrap" command to compile GCC I get an error (after a few minutes):

Any ideas?

It seems like you're missing a required libraries .
You see where it says
>>/tools/x86_64-unknown-linux-gnu/bin/ld: cannot find -lc

That means it cant find 'libc' . probably something like 'libc.so.6' or 'libc-2.3.6'.
I think you need to install Glibc . If you're doing LFS , you'll probably need to install 'Glibc-2.3.6' , then do GCC .


>>/tools/x86_64-unknown-linux-gnu/bin/ld: cannot find -lc
^If (when you run a configure script for the source you're building) you add 'x86_64-myos-linux-gnu' , you'll have your own custom target .

eg. ./configure --prefix=/usr x86_64-"put-distro-name-here"-linux-gnu
then it wont be targeted at 'x86_64-unknown-linux-gnu' .
(Its a good idea to specify your target for building Gcc+Binutils etc .)
