6 | # | ||
7 | # AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS]) | ||
8 | # | ||
9 | # DESCRIPTION | ||
10 | # | ||
11 | # For every FLAG1, FLAG2 it is checked whether the linker works with the | ||
12 | # flag. If it does, the flag is added FLAGS-VARIABLE | ||
13 | # | ||
14 | # If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is | ||
15 | # used. During the check the flag is always added to the linker's flags. | ||
16 | # | ||
17 | # If EXTRA-FLAGS is defined, it is added to the linker's default flags | ||
18 | # when the check is done. The check is thus made with the flags: "LDFLAGS | ||
19 | # EXTRA-FLAGS FLAG". This can for example be used to force the linker to | ||
20 | # issue an error when a bad flag is given. | ||
21 | # | ||
22 | # NOTE: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG. | ||
23 | # Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS. | ||

10 | # | ||
11 | # Check whether the given FLAG works with the linker or gives an error. | ||
12 | # (Warnings, however, are ignored) | ||
13 | # | ||
14 | # ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on | ||

17 | # If EXTRA-FLAGS is defined, it is added to the linker's default flags | ||

19 | # EXTRA-FLAGS FLAG". This can for example be used to force the linker to | ||
20 | # issue an error when a bad flag is given. | ||
21 | # | ||
22 | # INPUT gives an alternative input source to AC_LINK_IFELSE. | ||
23 | # | ||
24 | # NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this | ||
25 | # macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG. | ||
