Those are dynamically linked libraries, for what you know you could have libsupc++ statically linked to your libc++/abi or to at least of those libraries.<br><br>I'm not aware of any linux distribution or libc++ build under linux that is just using libc++ without libstdc++ or libsupc++, for what I know, at this point in time, libc++, at least under linux, is using libstdc++ and libsupc++ to provide a complete C++ support and filling the blanks that are still not supported by the library.<br>
<br>I think that libc++ will reach the indendpence from the GNU libs if and only if it will provide a complete C++ environment.<br><br><div class="gmail_quote">2013/7/29 Ben Pope <span dir="ltr"><<a href="mailto:benpope81@gmail.com" target="_blank">benpope81@gmail.com</a>></span><br>

</div>I've built libc++ against libc++abi on Ubuntu 13.04, and yes, you do<br>
need to specify -lc++ -lc++abi<br>
<br>
ben@localhost:/usr/lib$ ldd libc++.so<br>
linux-vdso.so.1<br>
libc++abi.so.1<br>
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0<br>
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6<br>
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6<br>
librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1<br>
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1<br>

<br>
libsupc++ is not required if libc++abi is used, and of course, libstdc++<br>
is also not required.<br>
<br>
In this configuration, with Clang 3.3, the llvm nightly test suite<br>
passes. (Ok, there is one failure, but it's the same as with libstdc++)<br>
