Subject: [PATCH] w32: Always use standard instead of native format strings
|
|||
|
|
MIME-Version: 1.0
|
|||
|
|
Content-Type: text/plain; charset=UTF-8

|
|
GLib 2.0 include files use __printf__ for the format attribute
|
|||
|
|
which resolves to native format strings on w32 hosts.
|
|||
|
|
|
|||
|
|
QEMU wants standard format strings instead of native format
|
|||
|
|
strings, so we simply change any declaration with __printf__
|
|||
|
|
to use __gnu_printf__.
|
|||
|
|
|
|||
|
|
This works because all basic printf functions support both
|
|||
|
|
kinds of format strings.
|
|||
|
|
|
|||
|
|
This fixes a compiler warning:
|
|||
|
|
|
|||
|
|
qapi/string-output-visitor.c: In function ‘print_type_int’:
|
|||
|
|
qapi/string-output-visitor.c:34:5: warning: unknown conversion type character ‘l’ in format [-Wformat]
|
|||
|
|
qapi/string-output-visitor.c:34:5: warning: too many arguments for format [-Wformat-extra-args]
