When I do this I install clang a directory whose name is in the path named
by the envariable "CLANG_DIR", and put the clang version in the envariable
named "CLANG_VERSION".
1. Then I compile using the command
"clang++ -nostdinc++ -std=c++11 -isystem
${CLANG_DIR}/lib/clang/${CLANG_VERSION}/include ..."
2. Then I link using the command
"clang++ -nostdinc++ -std=c++11 -L${CLANG_DIR}/lib -stdlib=libc++
-lc++"
I actually put all this in a CMakefile, and then generally forget what I
have done.
Variants of this let me build boost, poco, log4cpp and some other standard
libraries with clang and libc++.
For boost and poco you need to figure out how to use their build system,
which is harrowing, but
possible. For autoconf style systems you need to train them to not use
libstdc++, which they really,
really want to do. For me, this typically means editing the configure
script after autoconf does its
generation magic, since I'm too impatient and bored to figure out what
autoconf and automake really
are trying to do. (Log4cpp is an autoconf project.)
