Ibase SQL plugin build error on Windows 10 / MSVC 2017 64 bits for Firebird 3

[lqsa]

How compile the ibase SQL plugin for Fireberid 3 on Windows 10, MSVC 2017 64 bits?

Firebird is installed on D:\Firebird.

Executing this:

C:\Qt\5.9.2\msvc2017_64\bin\qmake "INCLUDEPATH+=D:/Firebird/include" "LIBS+=-lfbclient" ibase.pro

on C:\Qt\5.9.2\Src\qtbase\src\plugins\sqldrivers\ibase

Appears:

Project ERROR: Library 'ibase' is not defined.

After read this post: https://forum.qt.io/topic/75419/ibase-sql-plugin-build-error, I've commented QMAKE_USE += ibase on ibase.pro, but gives this error:

Cannot read C:/Qt/5.9.2/Src/qtbase/src/plugins/sqldrivers/qtsqldrivers-config.pri

This file doesn't exist. So, I've commented include($$shadowed($$PWD)/qtsqldrivers-config.pri) on qsqldriverbase.pri.

Now qmake finish ok.

When try to run nmake, it isn't found on the path, so I've executed this bat: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat"

After do:

cd C:\Qt\5.9.2\Src\qtbase\src\plugins\sqldrivers\ibase
nmake

appears a link error:

fbclient.lib doesn't exist, what can I do now?

Hi,

IIRC you have to configure Qt once and then you should be able to build the driver.

@SGaist How configure QT? I'm not compiling QT, I've installed QT with the installer.

[SGaist]

I didn't say you had to compile Qt, just configure it using the configure.bat script.

[lqsa]

@SGaist After run configure.bat, I've run again nmake, but appears the same error.

@lqsa "LIBS+=-lfbclient" - this is not enough, you need to tell the linker where it is located:

LIBS+="-LPATH_WHERE_LIB_IS_LOCATED -lfbclient"

[lqsa]

@jsulm It works! Thank you very much!.

Just say that fbclient.lib doesn't exist on Firebird, but it exists fbclient_ms.lib. Finally LIBS is: LIBS+="-LD:/Firebird/lib -lfbclient_ms"
