@edwinxxxx said in QMYSQL driver not loaded on mac:

how can i find the path like "opt/local..." on my machine?

find / -name libqsqlmysql.dylib

[edwinxxxx]

@jsulm sorry, i still cant find any folder whose name begin with "/opt/local..."

[jsulm]

@edwinxxxx "/opt" is a system folder just under root /

[edwinxxxx]

@jsulm is that mean i cant locate the file "libmysqlclient.xx.dylib" in my pc?

[jsulm]

@edwinxxxx No, it doesn't mean that. If it is somewhere on your machine you can find it.
Where did you install it?
Did you try what I suggested?

find / -name libmysqlclient.*.dylib

[edwinxxxx]

@jsulm Yes! it shows a lot of contents, and the related information is

[jsulm]

@edwinxxxx So, it is in /usr/local, not /opt/local.

[edwinxxxx]

@jsulm when i call "otool -L " it indicates that

libqsqlmysql.dylib (compatibility version 0.0.0, current version 0.0.0)
	@rpath/QtSql.framework/Versions/5/QtSql (compatibility version 5.9.0, current version 5.9.8)
	@rpath/QtCore.framework/Versions/5/QtCore (compatibility version 5.9.0, current version 5.9.8)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.50.2)

so according to other's experience i run

install_name_tool -change/usr/local/mysql/lib/libmysqlclient.20.dylib/usr/local/mysql-8.0.17-macos10.14-x86_64/lib/libmysqlclient.21.dylib/Users/edwinxxxx/Qt5.9.8/5.9.8/clang_64/plugins/sqldrivers/libqsqlmysql.dylib

however,it seems didn't work still.

I'm really not an MacOS expert, but don't you miss spaces here? Everything adter -change is one string without any separation via spaces.

[edwinxxxx]

@jsulm woooow! i add the spaces and the error disappear!
REALLY REALLY thanks!!!!
