Hi, 
I have a SO 64bit (not arm 64)  so I have downloaded the package manually to collect all libraries for cross compilation,it is true there are missing dependencies because there are many packages (on Windows all dll are under folder libs).
Now I am searching where  libpgcommon and libpgport where are installed.  I will install a SO arm64 to search library alternative I thinks should build Postgresql for Arm.
Thanks
Pier

Hi all,

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


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.
