Re: [avr-gcc-list] Trouble compiling avr-gcc > 4.4.4 on Mac OS X Leopard with gcc-4.2

Hi Johann,

Just to let you know: I really appreciate your help and quick replies *very* 
much.

Just to make it completely clear to a nut like me...
I do not need to do an actual build of GMP/MPFR/MPC before I build gcc ?

Nope.
Just to make sure you don't misunderstand what I'm trying to do (because the 
error-messages above are confusing!)
I'm only trying to do a simple build of avr-gcc on a PowerPC based Mac, which 
runs on a PowerPC based Mac, and generates code for Atmel AVR.

Remember..
Building gcc-4.2.4 up to 4.4.4 works fine, but as soon as I change the version 
number, and only the version number of gcc to 4.5.0 (or later), I get the above 
error.

This makes me think, that the way gcc is built/configured changed between 
v4.4.x and v4.5.x
-I could be wrong, but that seems to be the most logical explanation for me.

I could put the question in a different way:
Where would you look, if all previous versions of a build works, and after a 
certain version number, it won't build anymore ?
(Because I'm actually getting more or less stuck).

I'll try and expand my build-commands to not include any variables in the 
future.
The reason I didn't expand them earlier, was that the lines get so long, that 
they're difficult to overview. ;)

If you think I should ask the question on gcc-help instead; I'll do that; but 
I'll only ask one place at a time; as I feel asking the same question on 
multiple lists at the same time, is disrespectful.


Love,
Jens
