Hi, half of the pg_config output bits are more informational and not really supposed to be used for building other pieces of software. pg_config(1) says: --ldflags Print the value of the LDFLAGS variable that was used for building PostgreSQL. This shows linker switches. The same holds for CFLAGS: --cflags Print the value of the CFLAGS variable that was used for building PostgreSQL. This shows C compiler switches. I think these bits should simply be dropped from plugins/emperor_pg/uwsgiplugin.py. Its usage of `pg_config --includedir` is correct. (The usage of `pg_config --libdir` is correct, but useless in Debian because it's just the default lib dir.) Admittedly the fact that "usable" options like "--includedir-server" are intermixed with informational options like "--configure" is confusing. Christoph
