How to create the plugin of Firebird IBASE for QT 5.10

[Rudl]

Compiler: MSVC14
QT: 5.10
Firebird: 3.0.3
OS: Windows 10

I tried first to compile following these instructions: http://doc.qt.io/qt-5/sql-driver.html.

cd %QTDIR%\qtbase\src\plugins\sqldrivers
qmake -- IBASE_INCDIR=C:/interbase/include IBASE_LIBS=-lfbclient
nmake sub-ibase

But this didn't work. qmake gave me the output:

Configure summary:
QT Sql:
InterBase..........................................................no

After some research in the internet I found a solution:

Uncomment # QMAKE_USE += ibase in your ibase.pro.

Then compile the driver the old way:

cd %QTDIR%\src\plugins\sqldrivers\ibase
qmake "INCLUDEPATH+=C:\firebird\include" "LIBS+=C:\firebird\lib\lfbclient_ms.lib" ibase.pro
nmake

I hope this will save some of your time... :-)

Thank you so much, dear colleague!
I want to make a remark to create a driver for a bunch of Qt 5.13.2, Firebird 4.0 (beta) and MS VS 2017. In this case, for 32-bit.

Note. I have:

QT Installation Directory: D:\Tools\Qt
Firebird Installation Directory: D:\Tools\FB\Servers\40

1. Run cmd.exe.
2. Run the command:
   cd D:\Tools\Qt\5.13.2\msvc2017\bin
3. Perform:
   qtenv2.bat
4. Perform:
   "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build"vcvarsall.bat x86
5. Perform:
   cd D:\Tools\Qt\5.13.2\Src\qtbase\src\plugins\sqldrivers\ibase
6. Then open the ibase.pro file for editing, find the line
   QMAKE_USE + = ibase
   Put the comment character # at the beginning of the line:
   #QMAKE_USE + = ibase
   Save the ibase.pro file.
7. Perform:
   nmake clean
   8.Perform:
   qmake "INCLUDEPATH+=D:\Tools\FB\Servers\40\include" "LIBS+=D:\Tools\FB\Servers\40\lib\fbclient_ms.lib" ibase.pro
   9.Perform:
   nmake
8. Thats all! See results in
   D:\Tools\Qt\5.13.2\Src\qtbase\src\plugins\sqldrivers\plugins\sqldrivers

Thanks again.

I hope these lines also save some time.
