• Status: RESOLVED
• Resolution: INVALID
• Component: Tools / Tests

[Csaba Osztrogonác]

Build QtWebKit on Windows with MinGW, there are some "warning: unknown conversion type character 'l' in format":

..\..\..\JavaScriptCore\wtf\text\WTFString.cpp:404:36: warning: unknown conversion type character 'l' in format

We should use SCN... and PRI... macros from inttypes.h to avoid using %lli, %llu, ...

Fix 4 warnings:

JavaScriptCore\wtf\text\WTFString.cpp:404:
return String::format("%lli", n);

JavaScriptCore\wtf\text\WTFString.cpp:413:
return String::format("%llu", n);

WebCore\platform\sql\SQLiteFileSystem.cpp:76:
fileName = pathByAppendingComponent(dbDir, String::format("%016llx.db", seq));

WebCore\platform\sql\SQLiteFileSystem.cpp:79:

Fix this warning:
..\..\..\WebCore\loader\FTPDirectoryParser.cpp:191:47: warning: unknown conversion type character 'l' in format
..\..\..\WebCore\loader\FTPDirectoryParser.cpp:191:47: warning: too many arguments for format

I prefer PRI and SCN macros defined in inttypes.h, but 
I can't find any occurance of them in WebKit trunk.
Accordingly I propose a fix similar to String::number(...).

JavaScriptCore/wtf/text/WTFString.cpp:
...
String String::number(long long n)
{
#if OS(WINDOWS) && !PLATFORM(QT)
    return String::format("%I64i", n);
#else
    return String::format("%lli", n);
#endif
}
...

Bugzilla doesn't like me, but trac would be happy. ;)
