Unable to connect to Mysql on Mac
-
Hi and welcome to devnet,
Did you install MySQL for OS X ?
-
what does otool -L on libqsqlmysql.dylib return ?
-
Allready checked, all covered in the specific places. But for the record…
libqsqlmysql.dylib (compatibility version 0.0.0, current version 0.0.0)
/opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
/Users/**/Qt/5.2.0/clang_64/lib/QtSql.framework/Versions/5/QtSql (compatibility version 5.2.0, current version 5.2.0)
/Users/**/Qt/5.2.0/clang_64/lib/QtCore.framework/Versions/5/QtCore (compatibility version 5.2.0, current version 5.2.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)
Thnx a lot!
-
Then what error does QSqlDatabase return ?
-
Sorry, I meant the QSqlDatabase::error function
-
Yes that's it but I was hoping for more information since you have the plugin that seems to be built correctly.
Did you build it yourself ?
-
Not yet, because it didn't work at all. I thought it evt. could work since it comes in the package… however. I'm trying to build it again. After downgrading my server to mysql 5.5 version and adjusting the suggested links from the program internal help I'm stuck again:
qsql_mysql.o only in 32bit but it automatically tries to build in 64bit clang…omg
-
Are you trying to build the plugin in 32 bit ? Qt's in 64 bit by default
-
How did you install Qt ?
-
Hello again.
Now i managed to build the plugin successfully with latest versions.
But still the sample sqlbrowser doesn't load the driver.I also checkt all dependencies and tried having a copy of the driver libqsqlmysql.dylib and libqsqlmysql_debug.dylib as well as libmysqlclient.18.dylib to the project folder.
desperate again… a big thnx for any hints in advance!!
-
I'm working on osX 10.8.5, Qt Creator 3.01 (based on Qt 5.2.1 clang-64)
the driver is based on the same version src for sql-drivers and mysql 5.6.17 (x86_64) also properly working with workbench on localhost…the only thing could be that libmysqlclient.18.dylib wasn't built with clang-64. but how to solve that? the linker worked properly.
-
They must not be in the same folder as the application. Qt looks for the plugins in specific folders. What you must ensure is that llibqsqlmysql can get to libmysqlclient what does otool -L on both libraries return ?
-
Of course, putting them in the same folder as the project was an act of desperation. The links i've checked and all seemed fine to me - i found all the required files in pace.
The output of otool -L for libmysqlclient and libqsqlmysql in the clang_64/plugins/sqlservers folder:libmysqlclient.18.dylib:
libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)libqsqlmysql.dylib:
libqsqlmysql.dylib (compatibility version 0.0.0, current version 0.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) -
The id of libmysqlclient.18.dylib is just libmysqlclient.18.dylib so you either need to add the path containing that lib to DYLD_LIBRARY_PATH or update the id to use the full path to it.
