How to set "Runtime Library" in MSVC to "Multi-threaded [Debug] DLL" and some other settings?

[jgaa]

Hi,

I'm totally new to gyp.

I'm building the WebRTC project for use in another project, and need
to change some of the project settings globally. I figured it's easier
to do that in the gyp project file(s), rather than in the MSVC
project, each time I update the sources.

The most critical change is the Code Generation / Runtime Library
setting. Like most programs today, mine are using "Multi-threaded
[Debug] DLL", where Debug is used for the debug build. After spending
a few hours looking at gyp and it's wiki pages, I have not figured out
how to change this.

I also need to change the library output file for all the library
projects to "$(SolutionDir)\lib\$(ProjectName)_$
(ConfigurationName).lib" (using the Macro Expansion in Visual Studio).

And finally, I need to specify the names of the Program database Files
(they defaults to "vc80.pdb") to "$(TargetDir)$(TargetName).pdb" (also
here using the Macro Expansion in Visual Studio).

I hope someone will take the time to help me with these (probably)
very trivial questions. It will be greatly appreciated!

Best regards,

Jarle

Jarle,

   I'm new to gyp as well and had a similar problem. The lines in question to change how all webrtc libraries use the runtime can be found in \build\common.gypi. For example, I changed the values from:

'conditions': [

        ['OS=="win" and component=="shared_library"', {

          # See http://msdn.microsoft.com/en-us/library/aa652367.aspx

          'win_release_RuntimeLibrary%': '2', # 2 = /MT (nondebug DLL)

          'win_debug_RuntimeLibrary%': '3',   # 3 = /MTd (debug DLL)

        }, {

          # See http://msdn.microsoft.com/en-us/library/aa652367.aspx

          # sckime edit

          'win_release_RuntimeLibrary%': '0', # 0 = /MT (nondebug static)

          'win_debug_RuntimeLibrary%': '1',   # 1 = /MTd (debug static)

        }],

      ],

to

'conditions': [

        ['OS=="win" and component=="shared_library"', {

          # See http://msdn.microsoft.com/en-us/library/aa652367.aspx

          'win_release_RuntimeLibrary%': '2', # 2 = /MT (nondebug DLL)

          'win_debug_RuntimeLibrary%': '3',   # 3 = /MTd (debug DLL)

        }, {

          # See http://msdn.microsoft.com/en-us/library/aa652367.aspx

          # sckime edit

          'win_release_RuntimeLibrary%': '2', # 2 = /MT (nondebug DLL)

          'win_debug_RuntimeLibrary%': '3',   # 3 = /MTd (debug DLL)

        }],

      ],

This will update the project files if you call the following batch file from the trunk:

gclient runhooks --force
