For release configuration, the GenerateDebugInformation flag for VC project file results in having the following warnings:


7>Finished generating code
7>WebKitSystemInterface.lib(MediaUI.obj) : warning LNK4099: PDB 'webkitsysteminterface.vc80.pdb' was not found with 'C:\cygwin\home\buildbot\slave\win-release\build\WebKitLibraries\win\lib\WebKitSystemInterface.lib' or at 'c:\cygwin\home\buildbot\slave\win-release\build\WebKitBuild\Release\bin\webkitsysteminterface.vc80.pdb'; linking object as if no debug info

These warnings can be removed if we set the GenerateDebugInformation flag to false for the release configuration.

Fixing this in two projects which are affected by this library: QTMovieWin and WebKit2

Will this cause us not to generate PDBs for these projects at all in Release builds? That would be bad, because it would make them very hard to debug.

My apologies as I didn't notice about this perspective. Yes you are right, it will not generate any pdb for these projects which is bad.

Closing the bug.

Maybe we can tell the linker to ignore these warnings?

Yeah that would have been a desirable feature but unfortunately according to http://msdn.microsoft.com/en-us/library/b7whw3f3(v=vs.80).aspx this is not supported at least in Visual Studio 2005.
