Hello,

When compiling gcc 4.3.1 on sun Solaris I get the following error:

---------------------------------------

Of course gmp.h is there - the blimey "xgcc" compiler does not look at  
the right place:

-rw-r--r-- 1 xxxx xxx 81K 2008-06-18 10:39 /opt/gnat/gcc/include/gmp.h
---------------------------------------

And ignores any helpful hints:

---------------------------------------

ac_cv_env_CFLAGS_set='set'

CFLAGS='-B /opt/gnat/gcc/include'

---------------------------------------

Any ideas?

Don't do that.

RTFM, in particular the section http://gcc.gnu.org/install/configure.html
See --with-gmp...

You know, I have "build all script" which was able to create 4.2  
without trouble and now it can't.

Ohh, I know about "--with-gmp" - it somehow never made a difference no  
matter which "--with-gmp=" I used. I also tried "--with-gmp-include="  
and "--with-gmp-lib=pathname" - which made no difference as well.

I begun to think those options are placebos. But I have another try.  
Maybe it's  working after all - but I doubt that.

Martin

It might be a good idea to find out why these didn't work for you, since
they are, pretty obviously, intended to solve this specific problem.

We'll see.
