"Cannot find file: mysql.pro" while building MySQL driver in Qt


  • Hello everyone. I'm totally frustrated after tonns of tries on making connection between Qt and MySQL. I reinstalled both of them for many times and I saw different types of errors while I was trying to make connection MySQL&Qt. Right now I have such situation.
    I enter such commands in cmd
    C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql>qmake "INCLUDEPATH+=C:\MySQL-insalldir\MySQL Server 5.7\include" "LIBS+=C:\MySQL-insalldir\MySQL Server 5.7\lib\libmysql.lib" mysql.pro

    and i'm getting such error:
    Cannot find file: mysql.pro.

    I have all the pathes environment variables and i'm stucked on what I'm actually doing wrong.
    Please, help me.

    @CrowSun said in "Cannot find file: mysql.pro" while building MySQL driver in Qt:

    C:\MySQL-insalldir\MySQL Server 5.7

    You actually need the path to MySQL client library, not the server.
    Does C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql contain mysql.pro?

  • Can you please clarify where MySQL client library usually locates? I made everything as in docs and Installer puts in installation and data folders a folder named MySQL Server. So all needed libs (such as "...\include" and libmysql.lib) are located in that directives.
    And yes, there is no mysql.pro in " C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql" and that was also strange to me, because in my previous installation that path definitely contained that file. But it was another strange error which pushes me to reinstall Qt and MySQL. And now I get that error, that I described in the topic.

    Hi
    Just a note/question.
    If you do not select the source part in the installer. Will
    the mysql.pro be there ?

  • @jsulm I already have mysql connector. It was installed into Program Files folder by default. Actually installer doesnt even offers me choice of path. But, I tried that one:
    C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql>qmake "INCLUDEPATH+=C:\Program Files\MySQL\MySQL Connector C 6.1\include" "LIBS+=C:\Program Files\MySQL\MySQL Connector C 6.1\lib\libmysql.lib" mysql.pro
    and get the same "Cannot find file: mysql.pro." mistake

    @CrowSun Well, it doesn't make sense to call qmake as long as you don't have mysql.pro file.
    How did you install Qt source code?

    0

  • @mrjj I have only 3 files in that folder and it is:
    qsql_mysql_p.h
    qsql_mysql.pri
    qsql_mysql.cpp

    @jsulm i have downloaded file "qt-unified-windows-x86-3.0.2-online" and then just went through installation. I chose almost all components and Source part too.

    Hope you can help me...
    Big thank to all of you for replyings and not ignoring my problem!

    Hi,

    As an alternative, you can download the 5.7.1 source for Windows from here and check with that one.

  • @SGaist Okay, so I replaced components from my folder C:\Qt\5.7\Src with the components from that zip file and than I tried 2 commands below with such results:

    "C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql>qmake C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql>qmake "INCLUDEPATH+=C:\MySQL-insalldir\MySQL Server 5.7\include" "LIBS+=C:\MySQL-insalldir\MySQL Server 5.7\lib\libmysql.lib" mysql.pro
    Cannot read C:/Qt/5.7/Src/qtbase/src/sql/drivers/mysql: ???????? ? ???????.
    Error processing project file: C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql
    Cannot find file: mysql.pro."

    and this

    "C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql>qmake "INCLUDEPATH+=C:\Program Files\MySQL\MySQL Connector C 6.1\include" "LIBS+=C:\Program Files\MySQL\MySQL Connector C 6.1\lib\libmysql.lib" mysql.pro
    Cannot find file: mysql.pro."

    :(

    @CrowSun
    and
    cd C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql
    type mysql.pro
    lists the file ?

    Just in case, I've checked the content of the zip file and the /qtbase/src/plugins/sqldrivers/mysql/ folder contains mysql.pro.

  • @SGaist I actually find my super silly mistake. When I type command from C:\Qt\5.7\Src\qtbase\src\plugins\sqldrivers\mysql> command began to executing. BUT... then I get another error.
    So the picture looks like that:

    "C:\Qt\5.7\Src\qtbase\src\plugins\sqldrivers\mysql>qmake "INCLUDEPATH+=C:\Program Files\MySQL\MySQL Connector C 6.1\include" "LIBS+=C:\Program Files\MySQL\MySQL Connector C 6.1\lib\libmysql.lib" mysql.pro
    Info: creating stash file C:\Qt\5.7\Src\qtbase.qmake.stash"

    than I entered command:
    "C:\Qt\5.7\Src\qtbase\src\plugins\sqldrivers\mysql>mingw32-make"

    and get that error:

    "mingw32-make -f Makefile.Release all

    I already searched info about that mistake and someone says that this is a qt bug. Is it true?

    You'll likely have to escape the spaces in the path. Or use the good old 8.3 notation. By the way, use forward slashes for your path. Qt will handle conversion for your properly.

  • @mrjj I found mysql.pro in C:\Qt\5.7\Src\qtbase\src\plugins\sqldrivers\mysql and now I'm stacked with a new problem, which I described higher in my previous message.

  • @SGaist There isso much spaces in MySql folders by default. Idk how to avoid them properly.
    Anyway, i tries with forward slashes:
    "C:\Qt\5.7\Src\qtbase\src\plugins\sqldrivers\mysql>qmake "INCLUDEPATH+=C:/Program Files/MySQL/MySQL Connector C 6.1/include" "LIBS+=C:/Program Files/MySQL/MySQL Connector C 6.1/lib/libmysql.lib" mysql.pro"

    and get the same error...I made something wrong again?

    p.s. sorry, but what is that 8.3 notation? never heard before (shame on me)

  • @SGaist will it became a solution for my problem if I'll take all needed folders(include) and libs(libmysql.lib) to another created folder without spaces and use this new pathes in my command? Will it work or it will cause just a new problems?

    It should be good to build the plugin.

  • @SGaist so that solution is valid? to replace files in folder.
    Or I should avoid it and try an 8.3 notation?

  • Lifetime Qt Champion

    Replace ? I thought you wanted to copy the headers and libraries in their own folder without spaces. That or the notation should both work.

    Are you sure that your MySQL library is built for MinGW ?

  • @SGaist i'm so ashamed of my non-acquaintance, but no, I'm not sure.
    I have installed it with a "mysql-installer-community-5.7.21.0.msi" which I downloaded from official site.
    How I can figure out that my MySQL library is for MinGW?

    You can use Dependency Walker to see if it depends on the Visual Studio runtime.

    One other thing to check is whether your library is 32 or 64 bit.

  • @SGaist I uninstalled mySql from my pc and than I downloaded MySql community Server for windows 32bit (btw I have a 64bit windows). Than I unpacked zip archive in a folder without spaces and entered all previous commands in console. And FINALLY it all executed without errors.
    Thanks to everyone who replied on my topic and thank you SGaist for all answers and patience!
