I've changed from #include <postgres.h> to #include "postgres.h" and I still get the same error with Postgres 12 and it complies without any problem with Postgres 10 I dont understand why the output for Postgres 12 g++ -Wall -Wpointer-arith -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -O2 -o seal_diff_cpp.o -c seal_diff_cpp.cpp seal_diff_cpp.cpp:2:10: fatal error: postgres.h: No such file or directory 2 | #include "postgres.h" | ^~~~~~~~~~~~ looks different form the ones of Postgres 10 g++ -std=c++17 -fPIC -Wall -Werror -g -O0 -pthread -I/usr/pgsql-10/include/server -I/usr/local/include -I/usr/local/include/cppcodec -o seal_diff_cpp.o -c seal_diff_cpp.cpp g++ -shared -o seal_diff_cpp.so seal_diff_cpp.o -L/usr/pgsql-12/lib -L/usr/lib64 -Wl,--as-needed -Wl,-rpath,'/usr/pgsql-12/lib',--enable-new-dtags -L/usr/local/lib -lseal -pthread All the includes with "-I" and "-std=c++17 -fPIC" are from the first line gone. I even tried to use fixed paths in my Makefiles: "PGXS = /usr/pgsql-12/lib/pgxs/src/makefiles/pgxs.mk" and "INCLUDEDIR = /usr/pgsql-12/include/server".
