[Ma7moud El-Naggar]

i have this problem too
and i hope to find solution to this problem

[saa7_go]

This is how i build QMYSQL driver with MinGW/GCC.

1. create directory C:\mysql, C:\mysql\include, and C:\mysql\lib
2. copy mysql headers(*.h) to C:\mysql\include
3. copy libmysql.lib to C:\mysql\lib
4. use command prompt and change directory to C:\mysql\lib and run :
> reimp -d libmysql.lib
> dlltool -d libmysql.def -D libmysql.dll -l libmysql.a -k
5. change directory to mysql driver plugin(for example C:\Qt\2010.03\qt\src\plugins\sqldrivers\mysql) and run:
> qmake "INCLUDEPATH+=C:\mysql\include" "LIBS+=-LC:\mysql\lib -lmysql" mysql.pro
> mingw32-make all

Please help meee!!!

[Lykurg]

let me guess, you are using the command prompt for MSVC, because it tries to use it even if you are intend to use MinGW. So either use the right command prompt or while running qmake use the -spec flag and set the right file.

[jfabian]

Yes, I think that is the problem but MinGW is in : c:\qt\2010.04\mingw how can use MinGW command prompt, because I used QT command prompt and I get same error.

or what file should I run to execute the right command prompt??


or what can I do to use -spec flag?

can you write a example please?

[jfabian]

I resolved this problem uninstalling visual studio 6.0
