# Run command to generate makefile.
./configure

# Or you could use --prefix=/hawq/install/path to change the Apache HAWQ install path, 
# and you can also add some optional components using options (--with-python --with-perl)
./configure --prefix=/hawq/install/path --with-python --with-perl

# You can also run the command with --help for more configuration.
./configure --help

#Note: If ./configure complains that libyarn is missing, it is provided under ./depends/libyarn. 
# Please follow the above steps to install libyarn. You may need to run ldconfig after libyarn is installed.

# Run command to build and install
# To build concurrently , run make with -j option. For example, make -j8
# On Linux system without large memory, you will probably encounter error like
# "Error occurred during initialization of VM" "Could not reserve enough space for object heap";
# Try to set vm.overcommit_memory = 1 temporarily, and/or avoid "-j" build, and/or add more memory and then rebuild.
# On mac os, you will probably see this error: "'openssl/ssl.h' file not found". 
# "brew link openssl --force" should be able to solve the issue.
make -j8
 
# Install HAWQ
make install
