Can build Mysql Connector C++ on vs 2017? - visual-studio-2017

Question

I tried to build mysql-connector-c++ from source to static library.
Referring the official spec here, I generated the Visual studio solution by the following command:
cmake -DMYSQL_DIR="E:\mysql-5.7.21-winx64" -DWITH_BOOST="E:\libs\boost_1_67_0_BUILDED" -DWITH_JDBC=ON -G "Visual Studio 15 2017 Win64" ../
Then, I opened the vs solution generated by cmake.Run build, got the two libs: mysqlcppconn8-static-mt.lib, mysqlcppconn-static-mt.lib, and copied them to my project.
When I built my project (also vs2017 version), I got the error:
mysqlcppconn-static-mt.lib(net_serv.obj) : error LNK2038: 检测到“_MSC_VER”的不匹配项: 值“1800”不匹配值“1900”(ActionProcessor.obj 中)
I am confused. They're all built in vs2017, and platform toolset are all set to "Visual Studio 2017 (v141)". I can't understand where 1800_MSC_VER has come from.

Answer 1

Here is what I did
Specs
Visual Studio 15, (2017)
x64
Static (.lib)
With static runtime (/MT)
Tools
CMAKE
Bison (In a folder without spaces)
Perl (ActiveState or Strawberry)
OpenSSL 1.0.2q.tar.gz
Add CMAKE, Bison and pearl to your system path
Check to see if you got all setup correctly
C:\>cmake --version
cmake version 3.9.6
C:\>bison --version
bison (GNU Bison) 2.4.1
C:\>m4 --version
m4 (GNU M4) 1.4.13
C:\>perl -version
This is perl 5, version 24, subversion 3 (v5.24.3)
Step 1: Build OpenSSL 1.0.x
Note: if you want to build OpenSSL 1.1.x steps will be a bit different
Extract to: C:\mysql-8.0.15\openssl-1.0.2q
Run: x64 Native Tools Command prompt for VS 2017
cd C:\mysql-8.0.15\openssl-1.0.2q
Release
perl Configure VC-WIN64A no-shared --openssldir=.\rel64
ms\do_win64a
nmake -f ms\nt.mak
nmake -f ms\nt.mak install
Debug
nmake -f ms\nt.mak clean
perl Configure debug-VC-WIN64A no-shared --openssldir=.\dbg64
ms\do_win64a
nmake -f ms\nt.mak
nmake -f ms\nt.mak install
Step 2: Build MySQL (Yes the actual database)
Extract to: C:\mysql-8.0.15
Run: x64 Native Tools Command prompt for VS 2017
cd C:\mysql-8.0.15\
cmake . -G "Visual Studio 15 2017 Win64" ^
-DWITH_BOOST=C:/mysql-8.0.15/boost ^
-DDOWNLOAD_BOOST=1 ^
-DBUILD_CONFIG=mysql_release ^
-DWITH_SSL=C:\mysql-8.0.15\openssl-1.0.2q\rel64 ^
-DLINK_STATIC_RUNTIME_LIBRARIES=1
Copy m4.exe to C:\mysql-8.0.15\sql\ this avoids any m4.exe errors during built
Open MySQL.sln and build for release x64
Copy binary_log_funcs.h and binary_log_types.h from mysql-8.0.15\libbinlogevents\export to mysql-8.0.15\include
The library should be located at:
Static release library: C:\mysql-8.0.15\archive_output_directory\Release\mysqlclient.lib
Step 3: Build MySQL Connector C++
Copy C:\mysql-8.0.15-dbg\archive_output_directory\Debug\mysqlclient.lib
to C:\mysql-8.0.15-dbg\lib\vs14
Run CMAKE GUI
Browse to the path of the MySQL Connector Project.
Click Configure, Select Visual studio 15 2017 Win64, native compilers
Tick BUILD_STATIC
Tick STATIC_MSVCRT
TICK WITH_JDBC
remove WIN_SSL_YASL from CONFIG_VARS
WITH_SSL = C:\mysql-8.0.15\openssl-1.0.2q\rel64
WITH_BOOST= C:\mysql-8.0.15\boost\boost_1_66_0
MYSQL_DIR=C:\mysql-8.0.15
Open MySQL_CONCPP.sln build for Release x64
The library is located at:
C:\mysql-connector-c++-8.0.15\jdbc\install\lib\mysqlcppconn-static-mt.lib
C:\mysql-connector-c++-8.0.15\Release\mysqlcppconn8-static-mt.lib
Step 4: Test it
Note: This test is for the JDBC style API. If you are not maintaining an existing application, use the new xdevapi API.
Create a new project and put the following in main.cpp
#define WIN32_LEAN_AND_MEAN
#include <Windows.h>
#define STATIC_CONCPP
#define CONCPP_BUILD_STATIC
#define CPPCONN_PUBLIC_FUNC
#include <driver.h>
#include <connection.h>
#include <statement.h>
#include <exception.h>
sql::Driver *mDriver;
sql::Connection *mConnection;
int main() {
mDriver = get_driver_instance(); //or use: new MySQL_Driver()
try {
mConnection = mDriver->connect("host", "username", "password");
mConnection->close();
}catch(sql::SQLException& ex) {
std::cout << ex.what();
}
delete mConnection;
return 0;
}

Answer 2

I don't even know where to start explaining to be honest. Building this was a massive pain.
Before you begin to read this, please ensure you have the following:
C:\boost
C:\OpenSSL-Win32
C:\OpenSSL-Win64
Because I was writing my own "wrapper" and trying to make UNICODE work properly, I was getting weird exceptions, and I was unable to debug anything because I downloaded the latest package which is built without debug information (https://dev.mysql.com/downloads/connector/cpp/)
This is the first time I try to build this, so I went to their Github repository and grabbed the latest "master": https://github.com/mysql/mysql-connector-cpp
BUT! This does not contain the "JDBC" sources, which is by the way the "native" connector as they call it. So I grabbed it from the branch: https://github.com/mysql/mysql-connector-cpp/tree/jdbc and then copied the files into "mysql-connector-cpp-master\jdbc".
OK. I opened "x64 Native Tools Command Prompt for VS 2017" and navigated to "mysql-connector-cpp-master". At this point I still had no idea what I am doing and how to build it, all I could understand from the docs and different articles here is to run:
cmake -DWITH_JDBC=ON --build .
This started to configure things and build OK, but it stopped here:
-- Searching for static libraries with the base name(s) "mysqlclient"
CMake Error at FindMySQL.cmake:524 (message):
Could not find "mysql.h" from searching "/usr/include/mysql
/usr/local/include/mysql /opt/mysql/mysql/include
/opt/mysql/mysql/include/mysql /usr/local/mysql/include
/usr/local/mysql/include/mysql C:\Program Files/MySQL/*/include
C:/MySQL/*/include"
Call Stack (most recent call first):
CMakeLists.txt:332 (INCLUDE)
OK. So what now... where is "mysql.h" ?! After searching... and searching, I found this: Missing mysql.h and trying to find mysql-devel
And I quote:
Grab the MySQL Community Server and install it on your system. It
contains a directory called include in which you find the mysql.h.
Ok, great we need more stuff. So I download: https://dev.mysql.com/downloads/mysql/ and run the command again.
Happy days, something happened but no libs yet. I did get however a VS 2017 solution called: "MYSQLCPPCONN.sln".
This contains VS 2017 configuration to build the library for Win32. And of course trying to build with this solution will give you A LOT of unresolved external symbols.
So I run again the cmake but with static option added:
cmake -DWITH_JDBC=ON -DBUILD_STATIC=ON --build .
This time when I open "MYSQLCPPCONN.sln" I can see another project "mysqlcppconn-static" and this builds fine without issues.
However, in my case I need x64. I just created a new configuration for x64 by copying the exiting configuration fron Win32.
So that's it, I have both Win32 and x64 "mysqlcppconn-static.lib".
Overall Conclusion at this time:
Quite hard to build, without experience you will spend some time...
time.
No proper documentation, their existing documentation is poorly
written and very confusing.
No UNICODE support, yes the projects compile as Multi-Byte
Character Set.
I will see if I can debug and find out why am I getting exceptions in the library when using this (from their documentation):
sql::ConnectOptionsMap connection_properties;
connection_properties["hostName"] = "";
connection_properties["port"] = "";
connection_properties["userName"] = "";
connection_properties["password"] = "";
connection_properties["schema"] = "";
connection_properties["OPT_CONNECT_TIMEOUT"] = 10;
connection_properties["CLIENT_MULTI_STATEMENTS"] = (true);
connection_properties["OPT_CHARSET_NAME"] = "utf8";
connection_properties["OPT_SET_CHARSET_NAME"] = "utf8";
I hope you can build your library with this information, and hopefully in the future it will become more easier and clear.
Good Luck.
