I'm building many Visual Studio projects (.sln solutions files) from command-line with:
call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat"
for /r %%X in (/*.sln) do (
msbuild %%X /p:configuration=release /p:platform=win32 /nologo /noconsolelogger /fileLogger /v:quiet /flp:logfile=build_errors.log;errorsonly;append
)
Unfortunately, they all have been created with MSVS2010. Thus I get errors:
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.Cpp.Platform.targets(64,5): error MSB8020: The build tools for Visual Studio 2010 (Platform Toolset = 'v100') cannot be found. To build using the v100 build tools, please install Visual Studio 2010 build tools. Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Upgrade Solution...".
As I have 20 or 30 .sln files, I don't want to open each one and Upgrade solution, etc. (which I even didn't find exactly as mentioned here!).
Is there a command-line solution to upgrade all of them to MSVS2013 ?
