bitcoind not compiling on Mac OS X 10.11.1 #7110

I followed the instructions on:

https://github.com/bitcoin/bitcoin/blob/master/doc/build-osx.md

Dependencies, "autogen.sh" and "configure" all run smoothly:

brew install autoconf automake berkeley-db4 libtool boost miniupnpc openssl pkg-config protobuf qt5 libevent
./autogen.sh
./configure --with-gui=qt5

But "make" stopped with this error:

Do you have qt4 installed? Please upload config.log.

He has qt5 installed. Must be related to OSX10.11.1. Same setup works on my OSX 10.11 machine. Will update now to 10.11.1 and check.

Works for me on 10.11.1. Maybe try uninstall/reinstall qt5 over brew of try to switch to a older version (http://stackoverflow.com/questions/13477363/how-can-i-brew-link-a-specific-version).

If you still have problems, please post your config.log (pastebin).

• I just tried using "./configure" without specifying "--with-gui=qt5" but I get the same error.
• I have qt5 installed
• This is my config.log

Do you have qt4 installed as well on your machine somewhere?

Looks like an upstream problem with Qt developer headers. Can you compile other Qt5 applications?

pwd
/usr/local/Cellar
cd qt
qt/  qt5/
cd qt
ls
4.8.7

I'm going to reinstall qt

Hmm...

Differ your config.log. Could this be an issue:

-Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/4.2.1
+Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

I also see some boost issues on your config log. Can you post the output of brew info boost?

Try to upgrade to the newest Xcode version. Try to remove all brew qt5 and qt4 packages and reinstall qt5.5.1 (brew install qt5).

• I uninstalled all qt versions on my system and run "brew install qt5"
• I run "make" again and it worked!
• Just for reference:

I'm running Xcode 7.1.1, I think it is the latest stable build

Boost output:

Thanks for reporting! Closing.
