# _AC_LINKER_OPTION(LINKER-OPTIONS, SHELL-VARIABLE) |
| 103 |
# ------------------------------------------------- |
| 104 |
# |
| 105 |
# Specifying options to the compiler (whether it be the C, C++ or |
| 106 |
# Fortran 77 compiler) that are meant for the linker is compiler |
| 107 |
# dependent. This macro lets you give options to the compiler that |
| 108 |
# are meant for the linker in a portable, compiler-independent way. |
| 109 |
# |
| 110 |
# This macro take two arguments, a list of linker options that the |
| 111 |
# compiler should pass to the linker (LINKER-OPTIONS) and the name of |
| 112 |
# a shell variable (SHELL-VARIABLE). The list of linker options are |
| 113 |
# appended to the shell variable in a compiler-dependent way. |
| 114 |
# |
| 115 |
# For example, if the selected language is C, then this: |
| 116 |
# |
| 117 |
# _AC_LINKER_OPTION([-R /usr/local/lib/foo], foo_LDFLAGS) |
| 118 |
# |
| 119 |
# will expand into this if the selected C compiler is gcc: |
| 120 |
# |
| 121 |
# foo_LDFLAGS="-Xlinker -R -Xlinker /usr/local/lib/foo" |
| 122 |
# |
| 123 |
# otherwise, it will expand into this: |
| 124 |
# |
| 125 |
# foo_LDFLAGS"-R /usr/local/lib/foo" |
| 126 |
# |
| 127 |
# You are encouraged to add support for compilers that this macro |
| 128 |
# doesn't currently support. |

# Determine the linker flags (e.g. "-L" and "-l") for the Fortran 90 |
| 434 |
# intrinsic and run-time libraries that are required to successfully |
| 435 |
# link a Fortran 90 program or shared library. The output variable |
| 436 |
# F90LIBS is set to these flags. |
| 437 |
# |
| 438 |
# This macro is intended to be used in those situations when it is |
| 439 |
# necessary to mix, e.g. C++ and Fortran 90, source code into a single |
| 440 |
# program or shared library. |
| 441 |
# |
| 442 |
# For example, if object files from a C++ and Fortran 90 compiler must |
| 443 |
# be linked together, then the C++ compiler/linker must be used for |
| 444 |
# linking (since special C++-ish things need to happen at link time |
| 445 |
# like calling global constructors, instantiating templates, enabling |
| 446 |
# exception support, etc.). |
| 447 |
# |
| 448 |
# However, the Fortran 90 intrinsic and run-time libraries must be |
| 449 |
# linked in as well, but the C++ compiler/linker doesn't know how to |
| 450 |
# add these Fortran 90 libraries. Hence, the macro |
| 451 |
# "AC_F90_LIBRARY_LDFLAGS" was created to determine these Fortran 90 |
| 452 |
# libraries. |
| 453 |

# AC_F95_LIBRARY_LDFLAGS |
| 781 |
# ---------------------- |
| 782 |
# |
| 783 |
# Determine the linker flags (e.g. "-L" and "-l") for the Fortran 95 |
| 784 |
# intrinsic and run-time libraries that are required to successfully |
| 785 |
# link a Fortran 95 program or shared library. The output variable |
| 786 |
# F95LIBS is set to these flags. |
| 787 |
# |
| 788 |
# This macro is intended to be used in those situations when it is |
| 789 |
# necessary to mix, e.g. C++ and Fortran 95, source code into a single |
| 790 |
# program or shared library. |
| 791 |
# |
| 792 |
# For example, if object files from a C++ and Fortran 95 compiler must |
| 793 |
# be linked together, then the C++ compiler/linker must be used for |
| 794 |
# linking (since special C++-ish things need to happen at link time |
| 795 |
# like calling global constructors, instantiating templates, enabling |
| 796 |
# exception support, etc.). |
| 797 |
# |
| 798 |
# However, the Fortran 95 intrinsic and run-time libraries must be |
| 799 |
# linked in as well, but the C++ compiler/linker doesn't know how to |
| 800 |
# add these Fortran 95 libraries. Hence, the macro |
| 801 |
# "AC_F95_LIBRARY_LDFLAGS" was created to determine these Fortran 95 |
| 802 |
# libraries. |
| 803 |
# |
| 804 |
# This macro was copied from the Fortran 77 version by Matthew D. Langston. |
