Bootstrap failure configuring in-tree gmp in mainline

Bootstrap failure configuring in-tree gmp in mainline

[Bradley Lucier]

After configuring

Target: x86_64-unknown-linux-gnu
gcc version 4.5.0 20090715 (experimental) [trunk revision 149654] (GCC) 

with

../../mainline/configure --enable-checking=release --prefix=/pkgs/gcc-mainline-mem-stats --enable-languages=c --enable-gather-detailed-mem-stats

I get the bootstrap error:

Configuring stage 2 in ./gmp
< stuff omitted>
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

make[1]: *** [stage2-bubble] Error 2
make[1]: Leaving directory `/home/lucier/programs/gcc/objdirs/mainline'
make: *** [bootstrap] Error 2

This is using an in-tree gmp 4.3.0, gmp/config.log reports:

Am i missing something?

Does /home/lucier/programs/gcc/objdirs/mainline/./prev-gcc/g++ exist,
and if yes, is it a functioning executable?

If it doesn't exist, that looks like the toplevel logic for which
languages to build still has a loop hole for --enable-languages=c,
either not properly enabling the C++ compiler for stage 1, or wrongly
overriding CXX, CXX_FOR_BUILD in toplevel Makefile.tpl to point to
nonexistent previous-stage C++ compiler.  I don't know which is the
desired one.

BTW, what's the last <stuff omitted>, and why does your /lib/cpp try to
spawn cc1plus?

Cheers,
Ralf

Thanks for your reply.

No.

I put gmp/config.log at

http://www.math.purdue.edu/~lucier/bugzilla/10/gmp-config.log

and the build log (which is a bit confusing, I did a "make -j 6  
bootstrap > build.log" and then "make bootstrap >>& build.log" (in  
tcsh) to get a clearer message of the error at the end of the log) at

http://www.math.purdue.edu/~lucier/bugzilla/10/build.log

I tried building gcc like this on another machine, and it gets more  
confusing, at least to me.  When I put gmp-4.2.4 or gmp-4.3.0 in-tree  
on RHEL 5 with

leibniz-4% uname -a
Linux leibniz.math.purdue.edu 2.6.18-128.1.16.el5xen #1 SMP Fri Jun  
26 11:10:46 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

it works; when I put either in-tree on Ubuntu 9.04 with

heine:~/programs/gcc/objdirs/mainline> uname -a
Linux heine.math.purdue.edu 2.6.28-13-generic #45-Ubuntu SMP Tue Jun  
30 22:12:12 UTC 2009 x86_64 GNU/Linux

it fails.

No, it is a bug due to the build-with-C++ patches.  Please file a PR 
and, in the meanwhile, try --enable-stage1-languages=c,c++ or 
--enable-build-with-cxx.

Thanks!

That seemed to work, thanks, bootstrap has gotten past my old problem.

This fails with

Ah, I was too quick, it failed again at the next bootstrap stage.

Ah sorry I didn't understand you were doing --enable-languages=c.  You 
need to specify c++ there too.

I filed PR40950 for this.

I also filed PR40968 for an ICE on bootstrap when configured with -- 
enable-gather-detailed-mem-stats.
