configure: error: libprotobuf not found. and can not use apt-get to install libprotobuf-dev on Mac os 10.11.1 #7782

Error is

configure: error: libprotobuf not found.

I am using Mac os 10.11.1.

Tried to download apt-get through port

sudo port dpkg; sudo port apt;

apt-get install libprotobuf-dev, get following error:

Use port install protobuf-cpp

It works. That old error message is gone. Now I have a new error:

I had this problem before: #7269. At that time, I uninstalled port installed pkg-config, and brew install pkg-config. Then problem resovled.

The same way didn't solve problem today.

thanks a lot

Please read the the OS X build guide (https://github.com/bitcoin/bitcoin/blob/master/doc/build-osx.md). This time port install libevent should fix your problem.

BTW - what do you use port, brew or both? ;-)

@paveljanik your suggestion works like a charm. Brew uninstall libevent; sudo port install libevent, then problem fixed. thanks a lot

I am using both port or brew. Some of the packages seems to only in one of those.
