1402367 - Fix casing of windows includes in dom/media/platforms/wmf/WMFUtils.cpp

Status: RESOLVED FIXED

(Core :: Networking, defect)

Description

[Tom Ritter [:tjr]]

On Windows, filenames on case insensitive, but on Linux, they are not. Shlobj.h and Shlwapi.h cannot be found in the MinGW build because of this.

Are you saying that MinGW's headers are in lowercase? The Windows ones match the code:

C:\SDK>dir /s /b /a shl*.h
C:\SDK\10\Include\10.0.10586.0\um\ShlDisp.h
C:\SDK\10\Include\10.0.10586.0\um\ShlGuid.h
C:\SDK\10\Include\10.0.10586.0\um\ShlObj.h
C:\SDK\10\Include\10.0.10586.0\um\Shlwapi.h
C:\SDK\8.1\Include\um\ShlDisp.h
C:\SDK\8.1\Include\um\ShlGuid.h
C:\SDK\8.1\Include\um\ShlObj.h
C:\SDK\8.1\Include\um\Shlwapi.h

Yes, MinGW's headers are in lowercase. Microsoft isn't completely consistent, but does tend to put it in capitals: https://stackoverflow.com/a/15466951

I've fixed a bunch of these bugs before: Bug 1363465, Bug 1368416, Bug 1390617 and more that didn't come in a simple search.

Is there (or should there be) a bug against MinGW? I'll steal the review since Chris is out.

I think that ship has sailed. Since Linux is case sensitive, MinGW changing their casing would break (literally) everything.
