Building HHVM

Compiling and installing

cd ~/hhvm && \
cmake3 . && \
make -j$(($(nproc)+1)) && \
sudo make install

Alternatively compile with Zend Compat layer:

cd ~/hhvm && \
cmake3 -DENABLE_ZEND_COMPAT=ON . && \
make && \
sudo make install

Running HHVM on Amazon EC2

t1.micro

Because of its low memory, if you want to run HHVM on a t1.micro instance, you'll need to add the following to your config.hdf file (#1129):

Eval {
    JitASize = 134217728
    JitAStubsSize = 134217728
    JitGlobalDataSize = 67108864
}

Or the config.ini equivalent (not tested):

hhvm.eval.jit_a_size = 134217728
hhvm.eval.jit_a_stubs_size = 134217728
hhvm.eval.jit_global_data_size = 67108864

Beefier instance types don't have this issue, although it would still be a good idea to tweak your settings for your instance type.
