ARNING:
Some of the context lines in patches were ignored. This can lead to incorrectly applied patches.
The context lines in the patches can be updated with devtool:
devtool modify <recipe>
devtool finish --force-patch-refresh <recipe> <layer_path>
Then the updated patches and the source tree (in devtool's workspace)
should be reviewed to make sure the patches apply in the correct place
and don't introduce duplicate lines (which can, and does happen
when some of the context is ignored). Further information:

|
|
+# SYNOPSIS
|
|
+#
|
|
+# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
|
+#
|
|
+# DESCRIPTION
|
|
+#
|
|
+# Check whether the given FLAG works with the current language's compiler
|
|
+# or gives an error. (Warnings, however, are ignored)
|
|
+#
|
|
+# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
|
+# success/failure.
|
|
+#
|
|
+# If EXTRA-FLAGS is defined, it is added to the current language's default
|
|
+# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
|
+# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
|
+# force the compiler to issue an error when a bad flag is given.
|
|
+#
|
|
+# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
|
+#
|
|
+# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
|
+# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.
