Question

Has anyone successfully built gmock and gtest in Visual Studio 2010? I’ve tried with version 1.5.0, but I only get incomprehensible compilation errors.

Answer 1

I found this thread in google groups about issues found when building gmock-1.5.0 under VS2010. Following the thread, I’ve created a short readme file, which worked for me, so here it is:

• Download gmock 1.5.0 from Google Mock.
• Extract to library folder on the machine (e.g. C:\Libs\gmock-1.5.0). From now on, this folder will be reffered as ‘GMOCK_ROOT’.
• Open VS2010, and load the solution: GMOCK_ROOT\msvc\gmock.sln. Let VS convert it from VS2008 to VS2010. Important! DO NOT double-click the solution file under GMOCK_ROOT\msvc. This resulted in a bad conversion.

• Perform the following changes to sources according to the thread:

  • in project gmock –> Private Header Files –> gmock-internal-utils.h:

    • lines 201, 202: comment out the ‘Helper’ functions:

    char Helper(To);

    static char (&Helper(...))[2]; // NOLINT

    • lines 210-219: replace the entire #ifdef..#endif section with:

    static const bool value = std::is_convertible<From, To>::value;

  • in project gmock_test –> Source Files –> gmock-printers_test.cc, line 848:
    perform an explicit casting of the NULL argument to void*, otherwise VS will automatically regard it is a null int. The resulting line should look like this:

    t10(false, 'a', 3, 4, 5, 1.5F, -2.5, str, static_cast<void*>(NULL), "10");

    5. Build the solution. This should result in 4 warnings, which, as described below, are (probably) OK.

Hope this helps,

Boaz

Remarks regarding warnings:

1. Warnings 1,2 are about Copy() in xutility being deprecated due to safty. As the mock library is not a part of the production release, this is OK by me.
2. Warning 4 is OK according to the thread.
3. Warning 3: not sure, but all seems to work well.
