Re: building 'native', 'cross' and 'cross-native' GCCs

[Michael Zintakis <michael dot zintakis at googlemail dot com>]

I've installed and tried, in vain, to build my x86_64->powerpc (603e or 
G2 as it is also known) toolchain but was ultimately frustrated by failure!

The error I am getting and see no way around is during the "Installing C 
library" stage:

 make[3]: *** 
[/home/mz/gcc-test/build/powerpc-unknown-linux-gnu/build/build-libc/elf/librtld.map]

 make[2]: *** [elf/subdir_lib] Error 2

info on this error.

Googling "multiple definition of `_dl_addr_inside_object'" suggests a 
couple of things to try:

1. removing "-fstack-protector" (I use this option when building gcc);
2. force this by adding "-fno-stack-protector" to both the gcc and glibc 
builds;
3. use "-j1" instead of (my usual) "-j3"

Unfortunately none of this worked and I am really stuck and very 
frustrated, so would appreciate any help from the list with regards to 
how to overcome this problem.

My latest version of the .config file I used during the build is 
attached to this message (if it is scrubbed by the mailing list daemon 
please let me know and I will include it in-line as a separate message).

During the whole thing I discovered various bugs in crosstool-ng and 
also have a few suggestions/questions which I will post in a separate 
thread as I do not wish to pollute this one.

The versions of the packages I am using/building is:

gcc 4.5.2
gmp 4.3.1
mpfr 3.0.0
binutils 2.21
cloog-ppl 0.15.10
glibc 2.12.2
libelf 0.8.13
mpc 0.8.2
linux kernel 2.6.35
