None of the noise above about clang++ failing to be able to build a simple c++ program nor the missing string and cmath header files. Perhaps this is just a Debian Linux issue and has to do with upgrades to LSB 4.1 [Linux Standard Base 4.1], but then I don't know enough about LSB to know exactly how a compiler infrastructure would be impacted by it, if at all. [http://www.linuxfoundation.org/collaborate/workgroups/lsb/lsb-41-release-notes] NOTE: (The work on Libc++ under libcxx being put under /runtime and recognized by Cmake is still not working, from what I've seen, though work on it around 2 weeks prior was mentioned it would get added for Linux) - Marc -- Marc J.

Can you compile a Hello World C++ programa that uses iostreams with Clang? My guess is that clang's heuristics for locating g++ libraries and headers is failing on your setup. [snip]

[LLVMdev] [cfe-dev] Building past few days with Clang++ and Clang produces errors on Cmake for Debian Linux
*Resolution:* After doing an strace on the clang++ executable generated from gcc builds of llvm/clang I discovered some polluted gcc-4.7 intermixed and I had yet to install libstdc++6 (4.7) to build against. After doing so clang/clang++ worked as expected and have been doing so for well over a year of nightly builds from trunk. Unfortunately, I have a dilemma seeing as gcc/g++/cpp are all presently configured by Debian to target gcc-4.6 and therefore should not even have polluted the includes directories with anything but libstdc++6 (4.6.3) but that is an issue for Debian who seems to update it's libs in a mixed fashion without properly updating updates-alternatives for gcc to point to gcc-4.7 or until they have more of their distribution updated to hold both versions of libstdc++6 for 4.6.3 and a differentiated naming convention for the upcoming version, 4.7 instead of blatantly rewriting over the 4.6.3 libstdc++6 package with the 4.7 revision. - Marc On 03/27/2012 06:14 PM, Marc J.
