--- Comment #1 from Alex Lai <zclai at yahoo dot com> ---
on Solaris x86, I downloaded MPC, GMP and MPFR and extracted them into GCC
source directory as mpc,gmp and mpfr directories and configure GCC source with:

$ ../gcc-5.2.0.src/configure --prefix=$HOME/gcc-5.2.0 --enable-languages=c,c++
$ gmake

I got the following error:

Assembler: optimize.c
    "/var/tmp//ccMndPR3.s", line 85111 : Trouble closing elf file
gmake[3]: *** [cp/optimize.o] Error 1


The file mentioned in the error message doesn’t exist.

$ ls -l "/var/tmp//ccEtAJ5n.s"
/var/tmp//ccEtAJ5n.s: No such file or directory

The file system has plenty of room:

$  df -h /var/tmp
Filesystem             size   used  avail capacity  Mounted on
/dev/dsk/c0t0d0s6       99G    27G    71G    28%    /var

$  uname -a
SunOS sbdsvrwm566 5.10 Generic_150401-20 i86pc i386 i86pc


the only error message in config.log is as follows:

configure:5091: g++ -o conftest -g -O2   -static-libstdc++ -static-libgcc
conftest.cpp  >&5
g++: unrecognized option `-static-libstdc++'
conftest.cpp:11:2: #error -static-libstdc++ not implemented
configure:5091: $? = 1
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""
| #define PACKAGE_VERSION ""
| #define PACKAGE_STRING ""
| #define PACKAGE_BUGREPORT ""
| #define PACKAGE_URL ""
| /* end confdefs.h.  */
|
| #if (__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5)
| #error -static-libstdc++ not implemented
| #endif
| int main() {}


the lib exists and its path is included in lib search path:

$  ls -l /usr/local/lib/libstdc++.so
lrwxrwxrwx   1 root     root          18 May 31  2012
/usr/local/lib/libstdc++.so -> libstdc++.so.6.0.3
$  echo $LD_LIBRARY_PATH
/opt/SUNWspro11/SUNWspro/prod/lib:/usr/local/lib:/usr/lib:/usr/lib/X11


the error apparently is due to the missing space between -static and
-libstdc++. however,none of the mentioned confdefs.h conftest.cpp exist either
under the source or build directory or installed packages.

obviously the older gcc was used to compile the new gcc:

            Bug ID: 67068
           Summary: Ambiguous interfaces generated when including open mip
                    fortran header
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mwglass at sandia dot gov
  Target Milestone: ---

Using gfortran-5.2.0 with openmpi 1.8.7 on a Linux RHEL system.

When compiling a FORTRAN file  with "-freal-4-real-8 -fdefault-double-8
-fdefault-real-8" and having the file include the mpif.h header from openmpi,
gfortran generates the following error:

mpif-sizeof.h:575:41: c 'mpi_sizeof_real64_r7' and 'mpi_sizeof_real32_r7' in
generic interface 'mpi_sizeof' at (1)
mpif-sizeof.h:1139:42: Error: Ambiguous interfaces 'pmpi_sizeof_real64_r7' and
'pmpi_sizeof_real32_r7' in generic interface 'pmpi_sizeof' at (1)
mpif-sizeof.h:575:41: Error: Ambiguous interfaces 'mpi_sizeof_real64_r7' and
'mpi_sizeof_real32_r7' in generic interface 'mpi_sizeof' at (1)
mpif-sizeof.h:1139:42: Error: Ambiguous interfaces 'pmpi_sizeof_real64_r7' and
'pmpi_sizeof_real32_r7' in generic interface 'pmpi_sizeof' at (1)
mpif-sizeof.h:575:41: Error: Ambiguous interfaces 'mpi_sizeof_real64_r7' and

mpif-sizeof.h:1139:42: Error: Ambiguous interfaces 'pmpi_sizeof_real64_r7' and
'pmpi_sizeof_real32_r7' in generic interface 'pmpi_sizeof' at (1)

All previous versions of gfortran (4,7.x, 4.8.x, 4.9.x, 5.0, and 5.1) did not
do this. This also has never been a issue with the Intel fortran compile v14.x
and 15.x.
