Moc.exe

[xyz247]

When I try to compile my QMYSQL driver, I get an error (this is probably only one of many threads on this topic). "'C:\QtSDK\QtSources\4.8.1\bin\moc.exe' is not recognized as an internal or external command, operable program or batch file.". I have checked my BIN folder (C:\QtSDK\4.8.1\bin\) and no moc.exe exists, additionally I have searched my hard drive and it also could not be found.

Where can I find moc.exe? I have installed the QT SDK and I also have the sources (obviously). It's not present in either folders.

This whole compilation of MySQL drivers has so far been nothing but dreadful.

Full output

Qt Creator 2.4.1
Based on Qt 4.7.4 (32 bit)
Windows 7 (Home) x64

The binaries for a given version of Qt are under "C:\QtSDK\Desktop\4.8.x\bin" if you installed in the default location. If there is no moc.exe anywhere on your machine then either:

• You have not installed the Qt SDK at all, or
• You went out of your way to not install a set of compiled Qt libraries. You can remedy this with the SDK maintenance tool.

If you installed the SDK correctly then you have a Start Menu item to launch a correctly configured command shell. Use that.

Hi Chris,

Thanks again (you solved my last problem too). What you said worked, it just wasn't in the location that the error indicated. Now when I run qmake "INCLUDEPATH+=C:\mysql\MySQL Server 5.5\include" "LIBS+=C:\mysql\MySQL Server 5.5\lib" mysql.pro I get these errors:

Cannot find file: Server.
Cannot find file: 5.5\include.
Cannot find file: Server.
Cannot find file: 5.5\lib.

I know it's a problem with spacing in the installation path, however I am unable to change the install directory of a sub feature (MySQL Server 5.5 must be installed in the parent directory). How can I solve this?

The spaces in the paths to MySQL are definitely the problem. It's generally a good idea to avoid spaces in paths because a lot of scripts/utilities have issues.

You try using the short mangled name Windows gave the "MySQL Server 5.5" folder (perhaps MysqlS~1.5, but check):

qmake "INCLUDEPATH+=C:\mysql\MySQLS~1.5\include" "LIBS+=C:\mysql\MySQLS~1.5\lib" mysql.pro

qmake "INCLUDEPATH+=C:\mysql\MySQLS~1.5\include" "LIBS+=C:\mysql\MySQLS~1.5\lib" mysql.pro

To copy to clipboard, switch view to plain text mode 

or something like this (no guarantee):

qmake "INCLUDEPATH+=$$quote(C:\mysql\MySQL Server 5.5\include)" "LIBS+=$$quote(C:\mysql\MySQL Server 5.5\lib)" mysql.pro

qmake "INCLUDEPATH+=$$quote(C:\mysql\MySQL Server 5.5\include)" "LIBS+=$$quote(C:\mysql\MySQL Server 5.5\lib)" mysql.pro

To copy to clipboard, switch view to plain text mode

Thanks Chris, it worked (the last one). Well, off to my next error. This is painful. Why can't MySQL drivers be publicly available by Oracle?

[ChrisW67]

The MySQL drivers are publicly available. What you are are building is a small plugin to adapt the interface provided by the MySql drivers to the consistent interface that Qt expects of all SQL drivers: this is part of Qt and nothing to do with Oracle.
