Problem with linking runtime libraries on Windows for C++
Hi, I am trying to use Google Protocol Buffers run time libraries in my application. To use Protocol Buffers, I need to first build the run- time libraries for C++ on Windows.

Re: Sun Studio 11
Thanks for the patch!
It looks like you were using the examples as a test. Running make check
in the top directory will run a much better suite of tests -- do they pass?
Assuming it does work, can you re-send that patch as an attachment (it looks
like it has been mangled), or even send it to me via codereview.appspot.com?
Also, for me to submit it you'll need to sign the contributor license
agreement:

Re: Using dynamic library
Yes, you need to use the protobuf runtime library. Each language has an independent runtime library. libprotobuf.so is only for C++. For Java, there is a Maven-built jar file on which you need to depend. You don't need to link against the C++ dynamic library for Java apps.

I mean, protobuf is not header-only library? If yes, does the Java version requires the dynamic library, and how it is linked, when using Maven built JAR?

Re: Problem with linking runtime libraries on Windows for C++
Thanks for yoru response! I found that Microsoft Visual Studio was using the /MDd flag while compiling libprotobuf.lib. I changed it to use /MD which is what I am using to build my application. So now both are using the same flags, but I am still seeing the same error. I am linking the application against msvcrt.lib and msvcprt.lib which is what MSDN suggests for the /MD flag.

Re: Problem with linking runtime libraries on Windows for C++
/MDd is the debug library. libprotobuf.lib only links against it when built in debug mode. Are you also compiling your app in debug mode? You need to make sure to compile both projects in the same mode. Are you able to build the tests that come with the protobuf code? If so, maybe check what's different between the tests project and your project. Otherwise, I don't have any other ideas.
