# Makefile for liblmdb (Lightning memory-mapped database library).

# Configuration. The compiler options must enable threaded compilation.
#
# Preprocessor macros (for CPPFLAGS) of interest...
# Note that the defaults should already be correct for most
# platforms; you should not need to change any of these:
#
# 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 performance 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.
#	You might need to change this if the default size is too small.
