macOS Quick Start Guide SDK v2.9.x for Alexa Smart Screen SDK not tested for MacOS Monterey 12.3.1

I followed the directions tested for earlier versions of MacOS but when I tried to make -j8 after a long cmake, the MD5 function couldn't be found. I looked up online that the library openssl was no longer used for MD5 and instead that Common Crypto's version of MD5 was being used or I would have to disable openssl encryption in the cmake command as a command line argument with -DENABLE_OPENSSL_ENCRYPTION=0

Here are the errors for make -j8:

/Users/shyamalchandra/sdk_folder/avs-device-sdk/capabilities/AudioPlayer/acsdkAudioPlayer/src/Util.cpp:53:10: error: 'MD5' is deprecated [-Werror,-Wdeprecated-declarations]
    if (!MD5((uint8_t*), key.size(), hashOutput)) {
/usr/local/Cellar/openssl@3/3.0.3/include/openssl/md5.h:52:1: note: 'MD5' has been explicitly marked deprecated here
OSSL_DEPRECATEDIN_3_0 unsigned char *MD5(const unsigned char *d, size_t n,

In addition, at the end of the cmake before the make -j8, this happened:

Here are the steps I did on an installation of MacOS Monterey 12.3.1:


cd ~
mkdir sdk_folder
cd sdk_folder
mkdir sdk-build third-party sdk-install db
brew install curl (This is different than the instruction for earlier MacOS)
echo export PATH="/usr/local/opt/curl/bin:$PATH" >> ~/.zshrc
brew install gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-libav sqlite3 repo cmake clang-format doxygen wget git openssl@1.1
cd third-party

wget -c
tar xf pa_stable_v190600_20161030.tgz

# If you use MacOS Big Sur, install the following version instead
# wget -c
# tar xf pa_stable_v190700_20210406.tgz

cd portaudio
./configure --disable-mac-universal && make
brew info openssl@1.1
echo export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig:/_path-to-openssl_/lib/pkgconfig:$PKG_CONFIG_PATH" >> ~/.bash_profile
cd ~/sdk_folder
git clone --single-branch --branch v1.26.0
cd ~/sdk_folder   
git clone --single-branch --branch v1.8.1
cd ~/sdk_folder
git clone --single-branch --branch v1.8.3
cd ~/sdk_folder   
git clone


cd ~/sdk_folder/sdk-build
cmake -S ../avs-device-sdk -B . \
-DCURL_LIBRARY=/usr/local/opt/curl/lib/libcurl.dylib \
-DCURL_INCLUDE_DIR=/usr/local/opt/curl/include \
-DPORTAUDIO_LIB_PATH=$HOME/sdk_folder/third-party/portaudio/lib/.libs/libportaudio.a \
-DPORTAUDIO_INCLUDE_DIR=$HOME/sdk_folder/third-party/portaudio/include \
-DCMAKE_INSTALL_PREFIX=$HOME/sdk_folder/sdk-install \


make -j8 (I have 8 cores on my iMac i9)

4. I never got this step

make install

So, that is what happened. If you need any additional information, please let me know to compare and contrast your results with my Intel iMac. Thanks!
