How to link to libc++ on /usr/local/lib?

Question

I've tried to provide -L /usr/local/lib, tried -nostdinc++, tried to set DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH but otool aways gives me:

otool -L sample
sample:
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

How to link to my custom compiled /usr/local/lib/libc++.dylib on OS X?

Variations of compilation were upon basic clang++ -std=c++11 -stdlib=libc++.

As you've pointed out, oTool with -L is telling you that the libc++.1.dylib is being used from /usr/lib.

OSX development provides you with the command *install_name_tool*, which allows you to set the location of the required paths.

As an example, you'd use it something like this: -

install_name_tool -change /usr/lib/libc++.1.dylib /usr/local/lib/libc++.dylib <target file>

where the first path is the current path, the second is the one you want to change it to and the third is the file you're changing the paths for.
