Hi all,

I should use the client of Postgresql on Arm64, Host where i build is Ubuntu 20.04 64bit

I have downloaded the library from Ubuntu repository http://ftp.de.debian.org/debian/pool/main/p/postgresql-15/libpq-dev_15.5-0+deb12u1_arm64.deb

When I am building the library with libpq.a it shows following error,  probably there are missings libraries. Do you know the additional library that I need to link?

Did you directly download that one package, or install it via apt?  Because I wonder why it did not pull in the required dependencies.
