Makefile

# This is a simple Makefile to build RemoteCL.
# You should prefer to use the CMakeLists.txt instead, but on systems where CMake
# may not be readily available, this Makefile might just get you what you need.
# Please note that this file is provided merely for convenience and it may be outdated.

# Refer to the README.md for the usual configure options:
# ZLib is default enabled.
ENABLE_ZLIB ?= 1
# By default, enable the event stream
ENABLE_EVENT_STREAM ?= 1
# Where the Khronos headers are located.
KHR_INCLUDE_DIR ?= external/khronos
# Default CL version
CL_TARGET_OPENCL_VERSION ?= 220
# Default RemoteCL port.
DEFAULT_PORT ?= 23857
# Default RemoteCL client hostname.
DEFAULT_HOST ?= localhost
# Default OpenCL implementation for server linking.
CL_LIBRARY ?= OpenCL
# By default, the server will use fork()
USE_THREADS ?= 0

# Default c++ compiler to use.
CXX ?= g++
# Default optimisation level.
CXXFLAGS ?= -O2 -fPIC -DNDEBUG
# Use the GCC AR wrapper in case someone tries to -flto.
AR ?= gcc-ar
