Since I'm not specifying one by default, and there is no blacklist or whitelist, the fallback list is used. The first "compiler.fallback" on OSX 10.6 that meets the requirement to support "libc++" is "macports-clang-7.0". Not sure if this help anyone, but it explains why the dependency on clang-7.0 for cmake at least. - MLD</div></div></blockquote><br class=""></div><div>OK, but why then do you see this on OSX 10.6, but I don’t (i.e. see my first mail, with the clang/llvm deps) ?</div><div><br class=""></div><div>Something has to be different between the two, to get a different outcome.</div><div><br class=""></div><div>Chris</div><br class=""></body></html>
