- Subject: bootstrap comparison failure
Hi,
I'm trying to bootstrap gcc 4.1.1 for c, c++, and fortran on an OpenSUSE
10.2 box.
$uname -a
Linux psi 2.6.18.2-34-default #1 SMP Mon Nov 27 11:46:27 UTC 2006 i686
i686 i386 GNU/Linux
The installed gcc is
$gcc -v
Using built-in specs.
Target: i586-suse-linux
Configured with: ../configure --enable-threads=posix --prefix=/usr
--with-local-prefix=/usr/local --infodir=/usr/share/info
--mandir=/usr/share/man --libdir=/usr/lib --libexecdir=/usr/lib
--enable-languages=c,c++,objc,fortran,obj-c++,java,ada
--enable-checking=release --with-gxx-include-dir=/usr/include/c++/4.1.2
--enable-ssp --disable-libssp --disable-libgcj --with-slibdir=/lib
--with-system-zlib --enable-shared --enable-__cxa_atexit
--enable-libstdcxx-allocator=new --program-suffix=-4.1
--enable-version-specific-runtime-libs --without-system-libunwind
--with-cpu=generic --host=i586-suse-linux
Thread model: posix
gcc version 4.1.2 20061115 (prerelease) (SUSE Linux)
I started the build with
$../src/configure --prefix=[...]
$make bootstrap 2>&1 | tee make.log
The build seems to run fine, make bootstrap issues some warnings but
finally fails with a bootstrap comparison failure. I checked the
prerequisites and these seem to be fine. objdump -xtWD'ing the differing
files shows no differences while cmp does, so I'm a bit lost on how to
proceed.
Today I tried to compile a very simple c program, just a couple of lines
that print the ASCII character set. Comparing 5 builds of this showed
differences between some of them. Is this a reasonable indicator for my
system being one of the few systems where "meaningful comparison of
object files is impossible"? With previous releases of SUSE
bootstrapping worked, so this would have to be connected to the OS release.
Please let me know if you need any more information.
Cheers,
Christian
