C1083: Cannot open include fhile: 'QtSql': No such file or directory

JKyle145 · wrote on 21 Jul 2016, 21:26

I just installed 5.7.0, created a Qt Widgets Application, added sql (QT += core gui sql) to the .pro file and added '#include <QtSql>' to the mainwindow.h file. No other changes made. When compiling with 'MSVC2013 64 ' in Debug mode I receive the error noted. When I change to release mode, the program compiles and runs. I manually ran the qmake file with the basic parameters noted in the documentation. No effect. Any ideas on how to resolve?

Hi and welcome to devnet,

How did you install Qt ?

The include failure looks pretty strange. What if you include something like QSqlTableModel ?

Qt installation was with the main Windows install program with binary code. Changing the include file produced the same error except for the file name. Thank you.

In the pro file add:

QT+= sql

@NickV As noted the sql was added in the .pro file.

Did you check your Qt installation folder content ?

@SGaist The sub folders in the Qt 5.7 folder look normal. The appropriate bin folder has Qt5Sql.dll and Qt5Sqld.dll files. Anything else I should look for? During installation, I chose only 5.7 packages. Would older ones be helpful?

Build -> Run qmake and build again. Always do that when you edit .pro file.

@Chris-Kawa That does seem to have resolved the issue. Thank you.

The good all classic qmake re-run… :D
