Hi,
I'm trying to compile gcc 4.1.1 for the AVR platorm.
I compiled binutils 2.17 for the AVR platorm already and when I try to
compile gcc, I get the following error:
...
checking for avr-gcc...
/linux_source/gcc-4.1.1/host-i686-pc-linux-gnu/gcc/xgcc
-B/linux_source/gcc-4.1.1/host-i686-pc-linux-gnu/gcc/
-B/opt/avr/avr/bin/ -B/opt/avr/avr/lib/ -isystem /opt/avr/avr/include
-isystem /opt/avr/avr/sys-include
checking for C compiler default output file name... configure: error: C
compiler cannot create executables
See `config.log' for more details.
make[1]: *** [configure-target-libssp] Error 1
make[1]: Leaving directory `/linux_source/gcc-4.1.1'
make: *** [all] Error 2
....
The config.log file shows the following:
...
configure:2275: checking for correct version of gmp.h
configure:2288: gcc -c -g -O2 conftest.c 1>&5
configure:2278:17: gmp.h: No such file or directory
configure: In function `main':
configure:2282: error: `choke' undeclared (first use in this function)
configure:2282: error: (Each undeclared identifier is reported only once
configure:2282: error: for each function it appears in.)
configure:2282: error: parse error before "me"
configure: failed program was:
#line 2277 "configure"
#include "confdefs.h"
#include "gmp.h"
...
Where do I get gmp.h? Do I need it? What else can be wrong?
The following options were used to compile binutils 2.17:
./configure --prefix=/opt/avr --target=avr
My path is set to include /opt/avr then I tried to compile gcc 4.1.1
The following options were used to compile gcc 4.1.1:
./configure --prefix=/opt/avr --target=avr --enable-languages=c
--disable-nls
Thanks.
Aaron.

You seem to have achieved your goal already!

Can you in any way imagine that the subdirectory 'gcc' in the GCC
sources could be that
'GCC' ? So when it is "compiled", the compiler(s) called as "GCC"
is/are ready!

This error tells that the already built "GCC" for AVR cannot create
executables with
the help of the AVR targeted 'as' and 'ld', the AVR targeted C library etc.
Why the GCC build tries to build the 'libssp.a' for AVR as default and
whether it is required for
AVR at all, are the questions you should ask here. Anyway there should
be the GCC configure
option :
|--disable-libssp|
Specify that the run-time libraries for stack smashing protection
should not be built.
to disable it's build, so if you think it being not needed, just disable
it's build! A reconfigure
and a rebuild could show how you could get a clean working build but
just as well you could
try to remove the 'libssp' subdir from the
'/linux_source/gcc-4.1.1/host-i686-pc-linux-gnu/avr'
and then try 'make' again... If this doesn't help, then try removing the
'libssp' "target" from
the generated main GCC 'Makefile'.
> Where do I get gmp.h? Do I need it? What else can be wrong?
My thought is that you don't need 'libssp' for AVR at all...

Ok...I added the "--disable-libssp" and "make" went further but it stops
at another error:
.....
Entering directory `/linux_source/gcc-4.1.1/host-i686-pc-linux-gnu/gcc'
gcc -c -g -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings

What is "make" building here? Do I have a buggy avr-as? avr-as doesn't
have the '-Qy' option...should it? Or is "make" using avr-as
incorrectly here?
Thanks.

It is building executables for the $build platform...

> Or is "make" using avr-as incorrectly here?
As you can see the AVR 'as' was tried to be used with the native 'gcc'
! Why? Have you done
some weird environment settings or what? Maybe defining 'AS' to be this
'as' could cause this
but why anyone could do something like this?
One doesn't need to put anything else into the PATH than the
'$prefix/bin', your '/opt/avr/bin',
the stuff in '$prefix/$target/bin' will be found automatically with the
new GCC. Neither any
environment settings are required for 'AS' and 'LD', if one wants some
GCC-version specific
ones, putting them into the '$prefix/libexec/gcc/$target/$gcc-version'
among the 'cc1*' and
'collect2' executables there, would be the solution...

Hi Alee,
I follow a simple rule:
If I am getting compiler errors that I do not understand and if
(ideally) those erros should not have been there, then possibly
I am using the wrong toolchain. So, I go looking for the
latest/most appropriate toolchain.
Regards,
Amit
