Re: How to build mysqlclient.lib 5.7 without MSVCR120 dependency

[Adrián G.]

So I added the _ALLOW_RUNTIME_LIBRARY_MISMATCH flag, which I found, to MySQL solution generation command, like this:

cmake -Bbuild -G "Visual Studio 12 2013" -Tv120_xp -DCMAKE_CXX_FLAGS=/D_ALLOW_RUNTIME_LIBRARY_MISMATCH -DBUILD_CONFIG=mysql_release -DLINK_STATIC_RUNTIME_LIBRARIES=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=../my_boost -DWITH_SSL="C:\Program Files (x86)\OpenSSL" -DWITHOUT_SERVER=1

Afterwards, I can produce a mysqlclient.lib in MinSizeRel mode that can compile with my program in both Debug and Release modes. However, this change makes my program crash at mysql_end during mysql_real_connect. I wonder which difference/s this 'innocent' flag makes to the library that makes it incompatible in my program at runtime.

Anyway, if I opt out this approach and instead go the two separate Release/Debug mysqlclient libraries way (and after setting _HAS_ITERATOR_DEBUGGING=0 flag required to link within my program in Debug mode), my program crashes too at the same point in Debug mode.

Help, please. I know this might be quite advanced stuff, thoug.
