[Bug bootstrap/40833] New: gcc configure problem with mpfr.h

[david dot sagan at gmail dot com]

I am trying to configure gcc with:

lnx498:/nfs/acc/temp/dcs/gcc/gcc_tmp> ../gcc-4.4.1/configure
--prefix=/home/dcs/dcs/usr_local --with-gmp=/home/dcs/dcs/usr_local
--with-mpfr=/home/dcs/dcs/usr_local

Which gives:

checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c

$$f2
checking for correct version of gmp.h... yes
checking for correct version of mpfr.h... no
configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.2+.


But mpfr.h exists and is version 4.2.1:

lnx498:/nfs/acc/temp/dcs/gcc/gcc_tmp> grep VER
/home/dcs/dcs/usr_local/include/mpfr.h
#define MPFR_VERSION_MAJOR 2
#define MPFR_VERSION_MINOR 4
#define MPFR_VERSION_PATCHLEVEL 1
#define MPFR_VERSION_STRING "2.4.1"


The log file is:

lnx498:/nfs/acc/temp/dcs/gcc/gcc_tmp> cat config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ../gcc-4.4.1/configure --prefix=/home/dcs/dcs/usr_local
--with-gmp=/home/dcs/dcs/usr_local --with-mpfr=/home/dcs/dcs/usr_local

What do the following commands show

find /usr -name gmp.h
find /usr -name libgmp\*

It appears that you built mpfr against a different version of gmp.

Yes mpfr was built against a different version of gmp. 
I did not realize this would make a difference.
But how does this relate to the message that the version number in mpfr.h is
not correct when it is?

It has nothing to do with the version number.  Read the log file you
included in your original post.  You'll find

/home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to
`__gmpz_tdiv_q_2exp'
/home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to
`__gmpz_fdiv_q_2exp'
/home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to `__gmpz_clear'
/home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to

so the mpfr test never compiled and configure assumes the mpfr
test fails.  

It of course makes a difference.  mpfr must be linked with the version
of libgmp that was used when mpfr was built.

Thanks for the information. As I see it, the problem here is that the error
message from configure: 
  checking for correct version of mpfr.h... no
  configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.2+.
is wrong in this case. I would suggest that either 1) The error message be
changed to reflect the fact that other things could be wrong or, preferably, 2)
separate the mpfr test into pieces so accurate diagnostic messages can be
generated. 

-- Again Thanks, David

That is correct error since mpfr cannot be used as you configured gcc so it is
not the correct version :).

No. This is not correct. See comment #3. It has nothing to do with the version
of MPFR. The problem was that MPFR was built against a different version of GMP
than the GMP version specified on the configure line. 

So the error message is wrong.
