 |
|
I'm new to C++ to PostgreSQL interface using libpqxx.
And not sure if this is the right forum.
My guide is: https://www.tutorialspoint.com/postgresql/postgresql_c_cpp.htm
I have the ff emerged/installed:
1. GCC 11.2.0
2. PostgreSQL 13.3 (USE -server static-libs) - client libraries only
Note: server is on another PC
3. libpqxx 7.2.1
Source Code: https://pastebin.com/jHrRizAf
Compile: g++ -I /usr/include/pqxx/ -L /usr/lib64/ -I /usr/include/postgresql/ -L /usr/lib64/postgresql/ testPGcli.cpp -lpqxx -lpq
ErrorMsg: https://pastebin.com/MrjT9MHH |

If I use the command you posted,
| Code: | | g++ -I /usr/include/pqxx/ -L /usr/lib64/ -I /usr/include/postgresql/ -L /usr/lib64/postgresql/ testPGcli.cpp -lpqxx -lpq |
g++ emits the error messages you posted.
It works if I use
| Code: | | g++ testPGcli.cpp -lpqxx -lpq |
Don't ask me why... 
Please note that the examples on the tutorialpoint page are probably outdated. The tutorial was written for libpqxx-4.0. |
