I was able to install the pybind11 example here before I upgraded my MacOS. However, after I upgraded my MacOS to Mojave, when I compile the same example on that link, I see the following error:
clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'g++' failed with exit status 1
Am I missing a linker command? I've searched online but couldn't find a solution.
I actually found the answer. I only needed to do
export MACOSX_DEPLOYMENT_TARGET=10.9
The installation went smoothly.
