Location of Qt 5.4 source code
-
Hello
Please give me a prompt where I can get the source code of Qt 5.4?
And what is it's archive name?
Saying more precisely, I need \src\plugins\sqldrivers\oci directory.
I can find only old versions of Qt.Thanks
-
Hi,
"Here":https://www.qt.io/download-open-source/# you can find the source package. However you can also get the sources through the installer you used.

Thanks a lot
Maybe i'm just confused but every package i have downloaded doesn't seen to have folder \src\plugins\sqldrivers*folder_for_some_database*, e.g. \src\plugins\sqldrivers\oci... i just don't know where can i find files to build a database driver, which as i was told are not in the installation pack, but in the source code.
-
Because Qt's sources are not installed by default, you have to check that option to get them
-
So, I started my MaintenanceTool->Package manager.
Here is a list of items i had cheched before my instalation.
Qt
---|Qt 5.4
-------------|MinGW
-------------|msvc2013
-------------|Source Components (checked all options)
-------------|Qt WebEngine
---|Tools
-----------|MinGW
---|Qt Extras(checked all options)What else should be checked for the sources to be downloaded?
-
If you checked "Source Components", then it should be in C:<Qt>\5.4\Src
-
In the directory <Qt>\5.4\Src there are folders such as gnuwin32, qtactiveqt, qtandroidextras, qtbase etc.
But I still don't have any idea of the existence of \src\plugins\sqldrivers\ociI will try to explain more precisely what I need.
Here http://doc.qt.io/qt-5/sql-driver.html#qoci is described that I should build the SQL driver if i want to work with a database. As I don't have it in my list of drivers, viewed via QSqlDatabase::​drivers(), I have to build it on my own.
Here is the instruction(taken from that doc page):
@Build the plugin as follows (here it is assumed that Oracle Client is installed in C:\oracle):set INCLUDE=%INCLUDE%;c:\oracle\oci\include
set LIB=%LIB%;c:\oracle\oci\lib\msvc
cd %QTDIR%\src\plugins\sqldrivers\oci
qmake oci.pro
nmake
@
So I don't have either *src\plugins\sqldrivers\oci * or even imagination whre it can be found. In the previous versions of Qt I found the archive with sources, and the needed directory. But I can't find it for the 5.4 version.
Thanks for help
-
@ <Qt>\5.4\Src\qtbase\src\plugins\sqldrivers\oci@
-
yeah... Thanks a lot!
It was realy there...
Maybe it was just my fault but I think you should correct this path in the documentation.
-
One more question about the driver...
I did as in in the instructions:
@set INCLUDE=%INCLUDE%;D:\OClient\product\11.2.0\cl
ient_1\oci\include
set LIB=%LIB%;D:\OClient\product\11.2.0\cl
ient_1\oci\lib\msvc
cd %QTDIR%\5.4\Src\qtbase\src\plugins\sqldrivers\oci
qmake oci.pro
mingw32-make@so, as i understood, it has built me a driver, but i don't understand where it is now. the set PATH=%PATH%;D:\OClient\product\11.2.0\client_1\bin is set in my environmental variables. but calling the qDebug()<<QSqlDatabase::drivers(); doesn't print QOCI in the list of drivers.
now i have the next files in my 5.4\Src\qtbase\src\plugins\sqldrivers\oci directory:

After nmake, I believe you need nmake install

The documentation has been updated for the next release

Thanks for updating the documentation
Okay, i did mingw32-make install
So it copied qsqloci.dll and qsqlocid.dll to the sqldrivers and Qt5Sql_QOCIDriverPlugin.cmake (and i don't know what it is)
For being sure, i copied these .dll and libqsqlocid.a, libqsqloci.a to every folder which i thought could need them. When making a new project, qDebug()<<QSqlDatabase::drivers(); prints:
@("QSQLITE", "QMYSQL", "QMYSQL3", "QOCI", "QOCI8", "QODBC", "QODBC3", "QPSQL", "QPSQL7")@But after i had tried to connect to my database, it failed and lastError().text() returned the next: "Driver not loaded Driver not loaded"
My code of connection:
@qDebug()<<QSqlDatabase::drivers();
QSqlDatabase db;
db.addDatabase("QOCI");
db.setHostName("192.168.2.");
db.setDatabaseName("orcl.slesherdb.");
db.setUserName("");
db.setPassword("");
bool ok = db.open();
qDebug()<<db.lastError().text();@My listing of cmd after mingw32-make install

I'd say the obi dll(s) can't be found by your application. Go to the run part of the Project panel and update the PATH environment variable by adding "D:\OClient\product\11.2.0\client_1\oci\lib\msvc" if it contains the dlls or the corresponding folder in there
-
Unfortunately, it has already been added.
And it has also been added Windows folder, System32 folder, and the bin folders of Oracle client and Oracle server, where oci.dll is placed
-
I did as you wrote here:http://qt-project.org/forums/viewthread/21546
So I added new environmental variable QT_DEBUG_PLUGINS = 1
There are lots of things I can't understand

Did you check the environment variable value in the run part ? Depending on when you did your modification, it might be not up to date

I'm not sure if I understood you. I changed only PATH variable, the other ones are by default.
And I am confused why QT_DEBUG_PLUGINS tells me that some of .dlls are not plugins, or uses incompatible Qt library. (Cannot mix debug and release libraries.)
-
Some people change their system PATH rather than just in Qt Creator, that's why I asked the double check of PATH.
IIRC both debug and release dlls are stored in the same folder so Qt will check them all hence the incompatibility error message.
-
The problem is solved.
I have changed the part of code of connection:
@QSqlDatabase db;
db.addDatabase("QOCI");@instead of
@QSqlDatabase db = QSqlDatabase::addDatabase("QOCI");@
When I guessed to change back, everything was ok.
Thanks a lot to all!
