32bit Snow Leopard libc++11 dylibs

[Steven]

 Ok, thanks, but I am not inclined/too busy to learn macports. My app is cross platform, and supporting Mac is way too time consuming and hard already. (I already have three macs with 4 different OSX on them!).

My normal 32bit build system is actually using gcc from the command line on El Cap.Trying to install the new cxxabi.h and libs into /usr there triggers El Cap's no-write-to-usr "feature" which i have forgotten how to circumvent, and doubt it will work anyway (as you mention). Obviously i cannot compile it on Snow Leopard due to no c++11 support (and no macports)  on that system.

Compiling my app is not trivial either, due to it's Tcl/Tk dependancies.Thanks for the help though.

 there are a set of the required libs in here:

You'll need both libc++ and libc++abi,, and probably the symlink too, in your bundle. As you said, use install_name_tool to fix things up.

I have done such a bundling years ago, and it does work... but you would probably have to build the software on a 10.6 system or VM using macports for it to actually work out. We do some shenanigans to get libc++ to work right with 10.6. 

Simply using something built on 10.7 or 10.9 and linking it against that new libc++.dylib will most likely fail. Likewise, just setting the deployment_target to 10.6 on a newer system is also not likely to work, due to said shenanigans.
