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

[CrowSun]

@jsulm I forgot to reply on you message, when I answered to you.

[jsulm]

@CrowSun https://dev.mysql.com/downloads/connector/c/

[CrowSun]

@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

[mrjj]

Hi
And the mysql.pro file are in
C:\Qt\5.7\Src\qtbase\src\sql\drivers\mysql ?

[jsulm]

@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?

[CrowSun]

@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!

[SGaist]

Hi,

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

[CrowSun]

@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."

:(

[mrjj]

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

[SGaist]

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

[CrowSun]

@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:

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

[SGaist]

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.

[CrowSun]

@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.

[CrowSun]

@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)

[CrowSun]

@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?

[SGaist]

https://en.wikipedia.org/wiki/8.3_filename

It should be good to build the plugin.

[CrowSun]

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

[SGaist]

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

[CrowSun]

@SGaist I made a try with copying only now and in the end of that huge text block I receive an error.

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