How to solve these problems when I build mosquitto on macOS ？

[karlp]

Please read the https://github.com/eclipse/mosquitto#build-dependencies section. The cmake files are not smart enough to tell you directly about missing dependencies.

It doesn't look like the version of openssl you have has TLS PSK support. You could try to get something more modern, or disable TLS PSK support: cmake -DWITH_TLS_PSK=no should do it, but I haven't tested. Alternatively, I'd suggest you get it through homebrew.

[chipengliu]

@ralight I have installed openssl through homebrew , but I still haven't found out what the problem is.

openssl version
OpenSSL 1.0.2n  7 Dec 2017

[ralight]

In that case you need to find out the path to the homebrew installed openssl files and pass that as an argument to cmake so it can detect it. Something like:

cmake -DOPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2n/include -DOPENSSL_CRYPTO_LIBRARY=/usr/local/Cellar/openssl/1.0.2n/lib/libcrypto.dylib -DOPENSSL_SSL_LIBRARY=/usr/local/Cellar/openssl/1.0.2n/lib/libssl.dylib .

This appears to be solved based on the :+1: , so I'm going to close it.
