Error compiling C++ client example - dll-interface to be used by clients of class warnings

[Adnan Kobir]

Hello there,

Using the latest source for "mongo-cxx-driver-26compat", I've built the libraries using pre-built boost binaries and have built it using scons with the following arguments:

 C:\>scons --64 --full --use-system-boost --sharedclient --dynamic-windows --prefix="C:\mongo" --cpppath="C:\local\boost_1_55_0" --libpath="C:\local\boost_1_55_0\lib64-msvc-12.0" install-mongoclient

No issues so far.

Now in visual studio 2013 (msvc 12.0). I try to compile the following example:

Error 4 error C4996: 'strncpy': This function or variable may be unsafe. Consider using strncpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details. c:\mongo\include\mongo\util\goodies.h 153 1 Mongo155

Any help would be greatly appreciated!

[Andrew Morrow]

Hi -

The warnings are, unfortunately, unavoidable by our current understanding when building the library as a DLL. On the legacy branch we have added warning suppressions so these at least are hidden.

You do have one real error shown here, which is Windows complaining about use of strncpy. You should be able to eliminate this by defining _CRT_SECURE_NO_WARNINGS as suggested in the error message. Again, on the legacy branch, we suppress these warnings for you when using the dbclient.h or bson.h header.

Thanks,

Andrew

Thanks for the prompt response. I have added the _CRT_SECURE_NO_WARNINGS flag to the preprocessor and it does compile but the executable has a strange issue:

First-chance exception at 0x00007FFDE992606C in MongoTest.exe: Microsoft C++ exception: mongo::UserException at memory location 0x000000832F84EF80.

The thread 0x1040 has exited with code 0 (0x0).

The program '[7104] MongoTest.exe' has exited with code 0 (0x0).

When I try to run the application is get the following error:

2015-01-12T08:55:38.170-0500 getaddrinfo("@?AdX") failed: errno:11003 A non-recoverable error occurred during a database lookup.

caught can't connect couldn't connect to server @╤AdX:27017 (0.0.0.0), address resolved to 0.0.0.0

Seems that there is an issue with the connect string:

c.connect("localhost");

I've tried using 'localhost' and '127.0.0.1' - seems like whatever I type in, it comes out as garbage in the console for the connect address. Any ideas?

Are you linking your application with the same version of the runtime DLL as the library? Based on the build flags you used for building the C++ driver, you will want to build your application with /MD (see http://msdn.microsoft.com/en-us/library/2kzt1wy3.aspx) to select the Retail DLL version of the runtime.

Please note that support for building on windows is considerably improved on the legacy branch.

Thanks,

Andrew

Ok figured it out, for anyone else - ensure your C/C++ commandline in Visual Studio looks like this:

/GS /W1 /Zc:wchar_t /Zi /Gm- /O2 /Fd"x64\Debug\vc120.pdb" /fp:precise /errorReport:prompt /WX- /Zc:forScope /Gd /MD /Fa"x64\Debug\" /EHsc /nologo /Fo"x64\Debug\" /Fp"x64\Debug\MongoClient.pch" 

I believe it was an encoding issue that caused my connect string to come out garbled.
