Subject: [PATCH] romfs/tools: Silence GCC 8.1 compiler warning with
|
||
FLASHFS_MAGIC
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
GCC 8.1 introduce some new warnings which affect create_crc.c. One of
|
||
them is:
|
||
|
||
create_crc.c: In function ‘createHeaderImage’:
|
||
create_crc.c:110:2: warning: ‘strncpy’ output truncated before terminating nul
|
||
copying 8 bytes from a string of the same length [-Wstringop-truncation]
|
||
strncpy(uHeader.stHeader.magic, FLASHFS_MAGIC, 8);
|
||
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
Initialize the header struct statically here instead to silence the warning.
