trying to make a Windows 64-bit application
lazarus / 16-Databases

I've been banging around for a month or so trying to find a free
database that works nicely with Lazarus. Gave up on MySql because of
the connection to Oracle but never got it to work any how. (Never
could get a libmysql.dll to play happily; guessing it is the same
issue I found with PostgreSQl [see below].)

Same with MariaDb (libmysql.dll), which I would really like to have
used because Oracle's MySql workbench plays well with my MariaDb
database. Not a real fan of Interbase or Firebird even though I have 4
years of experience with them with Delphi 7.

Now, I'm banging against PostgreSQL 13. Figured out that the libpq.dll
I had was 64 bit (from a very helpful forum post.) Would have gone
with a 32-bit dll but PostgreSQL hasn't built one in a while.

So, now to my current issue. I'm trying to build a project as Windows
64-bit.

        [Please refer to my system-ppu_not_found.jpg.]
Notice the first line says the RTL file system.ppu is not found. Ergo,
I found it and put it in with the executable of my application.
Notice the last line says [the RTL system.ppu complete with it's fully
qualified path] is listed twice along with the system.ppu I put in
with my application executable.

Any help for a doddering old man would be appreciated.

Solved this. Found CFF Explorer and, using it, determined the dll's I
was using were 32 bit. Got the 64 bit dll's and it was all joy.
