# Configuration. The compiler options must enable threaded compilation.

|
|
|
|
|
# Preprocessor macros (for CPPFLAGS) of interest:
|
|
|
|
|
#
|
|
|
|
|
# To compile successfully if the default does not:
|
|
|
|
|
# - MDB_USE_POSIX_SEM (enabled by default on BSD, Apple)
|
|
|
|
|
# Define if shared mutexes are unsupported. Note that Posix
|
|
|
|
|
# semaphores and shared mutexes have different behaviors and
|
|
|
|
|
# different problems, see the Caveats section in lmdb.h.
|
|
|
|
|
#
|
|
|
|
|
# For best performence or to compile successfully:
|
|
|
|
|
# - MDB_DSYNC = "O_DSYNC" (default) or "O_SYNC" (less efficient)
|
|
|
|
|
# If O_DSYNC is undefined but exists in /usr/include,
|
|
|
|
|
# preferably set some compiler flag to get the definition.
|
|
|
|
|
# - MDB_FDATASYNC = "fdatasync" or "fsync"
|
|
|
|
|
# Function for flushing the data of a file. Define this to
|
|
|
|
|
# "fsync" if fdatasync() is not supported. fdatasync is
|
|
|
|
|
# default except on BSD, Apple, Android which use fsync.
|
|
|
|
|
# - MDB_USE_PWRITEV
|
|
|
|
|
# Define if the pwritev() function is supported.
|
|
|
|
|
#
|
|
|
|
|
# Data format:
|
|
|
|
|
# - MDB_MAXKEYSIZE
|
|
|
|
|
# Controls data packing and limits, see mdb.c.
|
|
|
|
|
#
|
|
|
|
|
# Debugging:
|
|
|
|
|
# - MDB_DEBUG, MDB_PARANOID.
