Top Forums Programming Linker errors linking to .a files on OS X Post 302928591 by Don Cragun on Saturday 13th of December 2014 03:29:36 AM
Also, check the output from the command:
file main.o func.o
It should be something like:
Code:
func.o: Mach-O 64-bit object x86_64
main.o: Mach-O 64-bit object x86_64

If you're seeing something other than x86_64 that is the problem. (But, I'm not sure how to tell gcc to produce x86_64 architecture code instead of whatever you're getting.)

NAME
qd-config - determine flags for compilation and linking SYNOPSIS
qd-config [options] DESCRIPTION
To link a Fortran-90 program with the C++ qd library, it is recommended to link with the C++ compiler used to generate the library. The Fortran 90 interface (along with a C-style main function calling f_main) is found in the qdmod library. The qd-config script can be used to determine which flags to pass to compile and link your programs. OPTIONS
--src Switch between source and system location. --prefix Output configured prefix value. --exec-prefix Output configured exec_prefix value. --build-flags Compiler options used during build. --build-libs Linker options used during build. --configure-args Configure arguments used for build. --cxx C++ compiler. --cflags C++ preprocessor and compiler options. --cxxflags C++ compiler options. --libs-la C++ linker options and libtool archive location. --libs C++ linker options. --fc Fortran compiler. --fcflags Fortran compiler options. --fclibs Fortran linker options. --fmainlib C++ linker options for main program written in Fortran. --version Output version.
