Hi, I got this initdb error for a 64bit-build on macOS El Capitan and Sierra: initdb -D /data/pg/hawk -E UTF8 --locale=C" The files belonging to this database system will be owned by user "rjhb". This user must also own the server process. The database cluster will be initialized with locale "C". The default text search configuration will be set to "english". Data page checksums are disabled. fixing permissions on existing directory /data/pg/hawk ... ok creating subdirectories ... ok selecting default max_connections ... 100 selecting default shared_buffers ... 128MB selecting dynamic shared memory implementation ... posix creating configuration files ... ok creating template1 database in /data/pg/hawk/base/1 ... ok initializing pg_authid ... ok initializing dependencies ... ok creating system views ... ok loading system objects' descriptions ... ok creating collations ... ok creating conversions ...

I configured with ./configure CC='gcc -m64' --prefix=/opt/bb/170704 and also tried with CFLAGS=-m64 LDFLAGS=-m64. With the same procedures, but 32-bit-builds, I don't get this error, and everything works fine. Unfortunately, I need the 64-bit version. Does the error ring a bell somewhere?
