How to change this linker?

checking whether the gcc linker (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld) supports shared libraries... yes

It seems that you have mismatch in boost somewhere. How did you install the dependencies? With Homebrew? Maybe check if MacPort or another package manager is installed and make sure, you remove all versions of boost and then reinstall it with Homebrew (check the build-osx doc).

@jonasschnelli
brew install boost the version is 1.66 and i have compile from source 1.60

./b2 install 

but now i don't know how to fix the dependencies

Hi, guys :D, I am a beginner in open source! How can I contribute to Bitcoin?

I've just tried compiling this on my x86_64 OSX machine with no issues. I have the same version of boost. You did use brew to install boost? I assume you followed the instructions ./doc/build-osx.mc. Also, what version of OSX are you running?

@Miskerest I have compiled it successfully, but now I can't locate the mistake。

What is the cause of this problem？Destruction of my compile environment

@kenneth - since your issue is now resolved, I'm going to close this issue. Feel free to re-open if you think this is still a problem.

I got the same issue with a port+brew double install of boost. I removed the port (1.55.0_0, 1.55.0_2 and 1.66.0_2) versions and the issue was removed as well:

sudo port uninstall boost  # all versions
