same problem but QPSQL DRIVER NOT LOADED

[SGaist]

Do you have PostgreSQL installed in some fashion ?
If so, how and where did you install it ?

[12bibi12]

@SGaist i have something named postgre https://postgresapp.com. its installed in my applications. /Applications/Postgres.app/Contents

[SGaist]

From the debug log, I would guess that you installed the 15 version of the application.

You have two options here:

• Install version 14
• Use install_name_tool to update the /Applications/Postgres.app/Contents/Versions/14/lib/libpq.5.dylib path to use the library from your installed Postgres.app

@SGaist i dont know exactly how to use install_name_tool.

do I write in my command install_name_tool with the path? I have never used it

[12bibi12]

@SGaist I tried instead installing version 14 but I got same error

[SGaist]

Did you check that ˋ/Applications/Postgres.app/Contents/Versions/14/lib/libpq.5.dylibˋ exists ?

As for ˋinstall_name_tool`, please read its help. It's really not complicated to replace a path with another one.

@SGaist I wrote this install_name_tool -change /Applications/Postgres.app/Contents/Versions/15/lib/libpq.5.dylib /Users/hayssamalsaffar/Qt/6.4.3/macos/plugins/sqldrivers/libqsqlpsql.dylib
and got this:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool [-change old new] ... [-rpath old new] ... [-add_rpath new] ... [-delete_rpath old] ... [-id name] input

[SGaist]

-change takes three arguments: old path, new path, file you want to change.

@SGaist I get this: error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't open file: libpq.5.dylib (No such file or directory)

i have checked in /Applications/Postgres.app/Contents/Versions/15/ and I have libpq5.dylib

@SGaist i made some changes and installed postgre 14 and got this instead. qt.core.plugin.factoryloader: checking directory path "/Users/hayssamalsaffar/Qt/6.4.3/macos/plugins/sqldrivers" ...

i dont if this is a step forward or step back

[SGaist]

Looks like the plugin is loaded so you are good to go.

@SGaist Thank you
