POSIX specifies strcasecmp/strncasecmp in <strings.h>, not <string.h>. On NuttX (and other strict POSIX environments) rcutils/src/strcasecmp.c only includes <string.h>, causing an implicit-declaration error for strcasecmp when cross-compiling. Patch 0003 adds #include <strings.h> guarded by !_WIN32, matching the existing Windows/POSIX split in the file. Signed-off-by: Arjav Patel <arjav1528@gmail.com>

Subject: [PATCH] rcutils: include <strings.h> for strcasecmp on NuttX
|
|
|
|
POSIX specifies strcasecmp/strncasecmp in <strings.h>, not <string.h>.
|
|
NuttX follows the standard strictly so omitting this header causes an
|
|
"implicit declaration" error. Guard the include with __NuttX__ so it
|
|
only applies where needed and does not affect Linux or other platforms
|
|
that already expose strcasecmp through <string.h>.
