Build DuckDB FDW

DuckDB FDW depends on the libduckdb.so dynamic library. On Ubuntu and Debian, you can directly use the precompiled binaries provided by DuckDB.

On EL-based operating systems, you need to compile libduckdb from scratch and use this version to compile duckdb_fdw.

Pigsty’s github.com/pgsty/pgsql-rpm repository offers pre-built templates:

• libduckdb
• duckdb_fdw

DuckDB has provided the libduckdb-src.zip source code, making it convenient for building.

Build Notes

You can only build this on EL8 & EL9 (EL7 not supported), to build duckdb_fdw, you also need to build libduckdb from source.

To build libduckdb-src, use the same building args as building duckdb_fdw:

clang++ -c -fPIC -std=c++11 -D_GLIBCXX_USE_CXX11_ABI=0 duckdb.cpp -o duckdb.o
clang++ -shared -o libduckdb.so *.o

To build libduckdb:

cd ~/rpmbuild/SPECS && make libduckdb

To build duckdb_fdw:

cd ~/rpmbuild/SPECS && make duckdb_fdw
