# In simple mode, by default all data needed for queries is now
# read into memory, using in total about 500 bytes per image. It
# is possible to select a disk cache using mmap for this instead.
# Then the kernel can read this memory into the filecache or
# discard it as needed. The app uses as little memory as possible
# but depending on IO load queries can take longer (sometimes a lot).
# This option is especially useful for a VPS with little memory.
# override DEFS+=-DUSE_DISK_CACHE

# If you do not have any databases created by previous versions of
# this software, you can uncomment this to not compile in code for
# upgrading old versions (use iqdb rehash <dbfile> to upgrade).
override DEFS+=-DNO_SUPPORT_OLD_VER

# Enable a significantly less memory intensive but slightly slower
# method of storing the image index internally (in simple mode).
override DEFS+=-DUSE_DELTA_QUEUE

# Set this if you have a C++11 compatible compiler with std::unordered_map
override DEFS+=-DHAVE_UNORDERED_MAP
# For GCC the C++11 support also needs to be enabled explicitly
override DEFS+=-std=c++11
# If your compiler is older and has std::tr1::unordered_map use this
# override DEFS+=-DHAVE_TR1_UNORDERED_MAP

# This may help or hurt performance. Try it and see for yourself.
override DEFS+=-fomit-frame-pointer

# Force use of a platform independent 64-bit database format.
override DEFS+=-DFORCE_64BIT

# By default iqdb uses integer math for the similarity computation,
# because it is often slightly faster than floating point math
# (and iqdb cannot make use of SSE et.al.) You can remove this option
# if you wish to compare both versions. This setting has
# negligible impact on the value of the similarity result.
override DEFS+=-DINTMATH
