**********************************************************************
|

It appears that your Fortran 77 compiler is unable to link against
|
|
object files created by your C compiler. This typically indicates
|
|
one of a few possibilities:
|
|
|
|
- A conflict between CFLAGS and FFLAGS
|
|
- A problem with your compiler installation(s)
|
|
- Different default build options between compilers (e.g., C
|
|
building for 32 bit and Fortran building for 64 bit)
|
|
- Incompatible compilers
|
|
|
|
Such problems can usually be solved by picking compatible compilers
|
|
and/or CFLAGS and FFLAGS. More information (including exactly what
|
|
command was given to the compilers and what error resulted when the
|
|
commands were executed) is available in the config.log file in this
|
|
directory.
