I'm trying to do the "x86_64-unknown-linux-gnu" build of gcc and g++
4.2.0. The machine I'm working on is an Intel Pentium D, which
apparently supports both 32 and 64 bit architectures. Although the
configuration succeeds, about halfway through the build step I get
this:
/tmp/foo/objdir/./gcc/xgcc -B/tmp/foo/objdir/./gcc/ -O2 -O2 -g -O2
-DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wold-style-definition -isystem ./include -I.
-I32 -I../../gcc-4.2.0 /gcc -I../../gcc-4.2.0/gcc/32

-I../../gcc-4.2.0/gcc/../libcpp/include
-I../../gcc-4.2.0/gcc/../libdecnumber -I../libdecnumber -m32 -g0
The '-m32' means this happening when producing the 32-bit startup...

In /usr/include/gnu there is a stubs-64.h and a stubs.h, but no
stubs-32.h. Is there some flag that I need to be passing at the
configuration or make step to make it see stubs-64 instead?
If there are the two required glibcs for 64-bit and 32-bit, then most
probably
is that header for the 32-bit production.... The 'gnu/stubs.h' for SuSE
10.1 is :
Dell:/opt # cat host-SuSE10.1_x86_64/usr/include/gnu/stubs.h
/* This file selects the right generated file of `__stub_FUNCTION' macros
based on the architecture being compiled for. */
#include <bits/wordsize.h>
#if __WORDSIZE == 32
# include <gnu/stubs-32.h>
#elif __WORDSIZE == 64
# include <gnu/stubs-64.h>
#else
# error "unexpected value for __WORDSIZE macro"
#endif
What does your one tell? Maybe you haven't installed any C-library support
for 32-bit ?
What is your x86_64 platform and why there isn't that support for 'bi-arch'
code production just as GCC expects there being ?
