Hi
Note that the _only_ difference in my two builds is the compiler. All
libraries, flags, etc are identical (so it may just mean that I need to
add another library - but which one?).
I have been trying to build my code on an Intel iMac - with gfortran 4.0.3
compilation & linking goes okay and the executable is usable (though there
are some unwanted features introduced by small bugs in the compiler, which
I believe may have been addressed in newer versions). With gfortran 4.2.0
I get the following error on linking (in both cases I use the command
"gfortran" for the linking, but this seems to explicitly invoke odcctools
in 4.2.0);
/sw/lib/odcctools/bin/ld: Undefined symbols:
__gfortran_filename
__gfortran_ioparm
__gfortran_line
collect2: ld returned 1 exit status
You must link against the gfortran 4.2 libraries when you compile with
4.2. In my limited experience, objects involving run time library calls
don't mix between 4.0, 4.1, and 4.2.
