mac os cannot build: Undefined symbols for architecture x86_64 _mallctl

[karol-bisztyga]

Hey!
I'm unable to build proxygen on my mac. I do

git clone https://github.com/facebook/proxygen.git
cd proxygen/proxygen
./build

I get following errors

[100%] Linking CXX executable logging_example

I get the same errors when I'm trying to build folly.
Any ideas?
Thanks

have you installed jemalloc?it seems like some symbols from jemalloc are missing

Please give it another try and reopen if it's still a problem
