Hello, I have just finished setting up my lovly new laptop apart from one thing. I need both the installed gcc 3.4.4 and a 4.x version of gcc. Here is what I did.
1. downloaded gcc-4.1.0 unziped e.t.c
2. Make a directory called making to make gcc in.
3. configure with
~/Desktop/gcc-4.1.0/configure --prefix=/opt/gcc41 --program-suffix=-4.1

So that gcc will be installed in /opt/gcc41 and have the suffix 4.1 (as I said this will be a seconadary compiler).
4. Then

make bootstrap

I get the error

make[2]: *** No rule to make target `../../build-i686-pc-linux-gnu/libiberty/libiberty.a', needed by `build/genmodes'. Stop.
make[2]: Leaving directory `/home/tommy/Desktop/making/gcc'
make[1]: *** [stage1_build] Error 2
make[1]: Leaving directory `/home/tommy/Desktop/making/gcc'
make: *** [bootstrap] Error 2

5. So I think maybe I should try and specify the host rather than the configure script guessing so i try

~/Desktop/gcc-4.1.0/configure --prefix=/opt/gcc41 --program-suffix=-4.1 --host=pentium-m

6. Again

make bootstrap

this time my error is

checking build system type... Invalid configuration `pentium-m': system `m' not recognized
configure: error: /bin/sh /home/tommy/Desktop/gcc-4.1.0/libiberty/../config.sub pentium-m failed
make: *** [configure-build-libiberty] Error 1

7. So obvesouly petium-m is not an option. so I try again specifing that

--host=i686-pc-linux-gnu
This of course just takes me straight back to number 4.

I am sure I must be missing something ver obveouse but I need your help.

This is good tutorial:

it helped me, i had the same problem!

ljubak thanks I'll have a look. I had just been remote working to another machine when I needed to use 4.1 but I do need to get it sorted. Lazy me.
