Apple M1 Special Needs

Computers with the Apple M1 chip require dedicated binaries, or binaries with both Intel and M1 contents. In order to get the hyrax-dependencies to build the following packages need to be installed prior to running the hyrax-dependencies build.

bison

• brew install bison
• export PATH="/opt/homebrew/opt/bison/bin:$PATH"

openssl

• brew install openssl
• export CPPFLAGS="-I/opt/homebrew/Cellar/openssl@3/3.0.1/include"
• export LDFLAGS="-L/opt/homebrew/Cellar/openssl@3/3.0.1/lib"
• sudo ln -s /opt/homebrew/Cellar/openssl@3/3.3.0 /usr/local/opt/opensslexport

jpg

• brew install jpg
• export PATH="/opt/homebrew/opt/jpeg/bin:$PATH"
• export LDFLAGS="-L/opt/homebrew/opt/jpeg/lib $LDFLAGS"
• export CPPFLAGS="-I/opt/homebrew/opt/jpeg/include $CPPFLAGS"

libpng

This is needed to build the gdal library in the hyrax-dependencies.

• Download libpng source

Unpack the distribution bundle and build and install the library into /usr/local

• ./configure
• make
• make check
• make install
