QMake can't find MySQL
-
Hi there,
I have been reading the documentation on how to build the MySQL driver. Here is my setup:
- Windows 10
- MySQL Server v8.0.18 (64-bit) (installed under "C:\Program Files\MySQL")
- MySQL Connector C++ v8.0.18 (installed under "C:\Program Files\MySQL")
- MSVC 2017 (64-bit) to compile
- QT 5.13.2 w/ Sources, and Debugging Tools for Windows
Going through the documentation, I am running the following command:
cd C:\Qt\5.13.2\Src\qtbase\src\plugins\sqldrivers qmake -- MYSQL_INCDIR="C:\Program Files\MySQL\MySQL Server 8.0\include" MYSQL_LIBDIR="C:\Program Files\MySQL\MySQL Server 8.0\lib"and the output is:
Running configuration tests... Checking for DB2 (IBM)... no Checking for InterBase... no Checking for MySQL... no Checking for OCI (Oracle)... no Checking for ODBC... no Checking for PostgreSQL... no Checking for SQLite (version 2)... no Checking for TDS (Sybase)... no Done running configuration tests. Configure summary: Qt Sql Drivers: DB2 (IBM) .............................. no InterBase .............................. no MySql .................................. no OCI (Oracle) ........................... no ODBC ................................... no PostgreSQL ............................. no SQLite2 ................................ no SQLite ................................. yes Using system provided SQLite ......... no TDS (Sybase) ........................... noIs there a way to determine why this is failing? I don't see why it isn't picking up the MySQL libraries.
Thanks,
John

@jsulm Thanks jsulm, that got it to recognize MySQL! I guess the default developer command prompt within Visual Studio is either the x86 or mixed environment. Just a note, I had to use 'x64 Native Tools Command Prompt for VS 2019' to get it to recognize, the cross tools one wouldn't recognize it.
That solves this issue specifically, as I get the output needed.
Thanks everyone for your help.

Hi and welcome to devnet,
You should have test logs. They will contain the various tests done and why they failed.

Thanks SGaist, it appears NMAKE is failing to find windows.h, here is the most relevant log:

Should I add that directory to the PATH?

@cawlfj said in QMake can't find MySQL:
QT has no a details step for it long time .
At least the error above is not Qt's fault - when the compiler can't find windows.h then it was not set up correct...

@cawlfj Thanks for the suggestion, I just installed VS Studio 2019. I also deleted the config.cache, .opt, .summary and .log files before running again. After running the following within the VS studio developer command prompt:
cd C:\Qt\5.13.2\Src\qtbase\src\plugins\sqldrivers qmake -- MYSQL_INCDIR="C:\Program Files\MySQL\MySQL Server 8.0\include" MYSQL_LIBDIR="C:\Program Files\MySQL\MySQL Server 8.0\lib"I get the same output where it doesn't see MySQL, and an architecture conflict in the log:

Does that mean something is wrong with my environment variables?
