# _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. |

# For example, if object files from a C++ and Fortran 90 compiler must |

444 |
# linking (since special C++-ish things need to happen at link time |
