Undefined symbols for architecture x86_64

[TannyXie]

I'm on MacOS and using g++-11. I have added all the dependent libraries into my path. This is the error when I try to compile a piece of code from the test code.

Undefined symbols for architecture x86_64:

This appears to be failing to link against boost::context, glog, and at least a couple parts of Folly. How are you currently attempting to link against folly?

[TannyXie]

I exported the CPLUS_INCLUDE_PATH to /usr/local/Cellar/boost/1.78.0_1/include:/usr/local/Cellar/glog/0.5.0/include, which are the paths I found with brew info.

Hi @TannyXie - I encountered the same issue - did you happen to resolve it somehow?

[mwiewior]

export LDFLAGS="-lglog -lfolly -L/usr/local/lib"

did the trick for me.
