[Bug bootstrap/45737] New: Bootstrap comparison failure

[iek at c-w dot be]

Hi,


I'm building gcc 4.5.1 and I encounter the below error:

"
Comparing stages 2 and 3
warning: gcc/cc1-checksum.o differs
Bootstrap comparison failure!
gmp/mpn/sb_div_q.o differs
mpfr/get_d.o differs
make[2]: *** [compare] Error 1
make[2]: Leaving directory `/tmp/IEK2/gcc-4.5.1-build'
"

This build is on a linux IA64 system, making use of gcc 3.4.6.

THe configure was run with the below command:
 configure --prefix=/opt/third/gcc-4.5.1   --enable-languages=c 

And then simply running make.

I had several times problems (for each stage) due to missing gmp_impl.h and
longlong.h but solved with a manual copy from the sources.

Note that I succeeded to make the same gcc 4.5.1 build installation on a AIX
5.3 but on the linux I have the above issue that is quite blocking for the
build.


THanks upfront for keeping me informed on any possible way to investigate,
Kind regards,

Is it a solution to build GCC with --disable-bootstrap option.

The host and build machine for the gcc is the same on a IA 64 redhat linux.

In order to avoid the issue ....

Tks upfront,

I haven't seen this failure but I don't build with GMP and MPFR in my build
tree.  They are installed on the system instead and I use --with-gmp=<DIR> and
--with-mpfr=<DIR> on the configure line to point to where they live.  Doing the
build this way might give you a workaround if it is only the gmp and mpfr files
that differ during the bootstrap.
