What do I miss...?
The ability to clearly describe your problem!
Sorry I tried to be minimum... But here are more details?
What did you do?
I assume you wrote some c code.
Yes, this code above is written in c (c++ in fact but I have simplified).
Did you compile it? And if so, how?
Yes, with default tools (gcc under debian bulllseye linked with libodbc)
You installed odbcunix I assume.
How did you configure it?
Correctly.
What is the output of "odbcinst -q -d"?
Correct :
[PostgreSQL ANSI]
[PostgreSQL Unicode]
What did you expect?
That my c program produces the same list
What did not work?
Include logs, error messages.
Logs and error messages : none (This is the heart of the problem)
What did you do to solve your problem so far?
I have reduced my problem - which is much more complex - to the simplest
test prograam.
And I ask for help, as I have no more idea after many hours.
