Re: BUG #17733: ERROR: could not load library "/Users/frank/postgres/postgresql-13.9/lib/postgresql/llvmjit.so": dl - Mailing list pgsql-bugs

Dear Andres, dear list,

it's just only llvmjit.so which (weirdly) links to libncurses.6.dylib here in EDBs postgresql-13.9 build - nothing else.

Neither plpgsql.so nor libpq.dylib reference libncurses.6.dylib - to answer your specific question about them.

Since I agree that this is no classic pgsql bug at all - I too wonder how to lure someone at EDB on this matter.

There  seems no community support mail - just options for users owning a 'plan' ( I at least couldn't figure one out ).

But it too seems that EDB staff lurks in here on a regular basis - so my hope was to have them pick it up from here ;)

FWIW - I'll CC Sandeep Thakkar (from former issue #16460) in good hope to get things sorted.

Thankyou!

cheers,

Frank Reppin

That looks like an issue with the specific build - you're going to have to
take that up with EDB.

It's pretty odd that llvmjit.so is linking to ncurses. Looks like some
compiler flags might have been injected in a too broad way.

Are other libraries, e.g. plpgsql.so and libpq.dylib also referencing ncurses?
