Lazarus, MacOS, MySQL and ZComponent debugging
lazarus / 16-Databases

Hello everybody.

I am writing an application which connects to a remote MySQL DB using
the last version of Component. It runs and I can debug it under
Windows, it runs under Mac if launched via Terminal, but no way to
debug it from the IDE: it says it cannot find the client library for
MySQL and stops. It seems to me I have set everything correctly, the
debugger is LLDB, and I can debug other apps not using ZComponent.
- Free Pascal Compiler version 3.2.2 [2021/05/16] for aarch64 (but I
am compiling for x64)
- Lazarus 2.0.12
- libmysqlclient.20.dylib (for MySQL 5.7) stored in the same folder of
the app
- MacOS BigSur running on M1

Any suggestion for me?

Many thanks
Paolo

Have you tried the Full Path to the dylib?

The first thing I did was to use the Library property, set to
'./libmysqlclient.dylib'; both libmysqlclient.20.dylib and
libmysqlclient.dylib (alias to it) were into the same folder of the
app.

right now I have debugger working under MacOS:
- installed MySQL on my Mac using Homebrew
- adjusted .profile_bash and symlink to the installed library
- set Library property to empty string

I prefer a 'non installation' of MySQL on customers machines, but it
will be a problem in the future.
