如何在C ++ 11和新的STL中使用GSL？

Question

I am setting up a new C++ project (in Xcode 4.6) and I would very much like to use the features of the new C++11 standard (lambda expressions, auto, etc.). I am trying to (statically) link the Gnu Scientific Library (GSL) into this project, using Darson's answer to this previous question. However, his answer suggests to change the compiler to LLVM GCC 4.2, which does not support the new C++11 features.

When I change to the default Apple LLVM compiler 4.2, build fails and I get a long list of errors that Xcode traces back to semantic issues (undeclared identifiers, unknown type names, etc.) in the headers of the new "libc++" STL.

So my question is: Did anyone find a way to use GSL in the new C++11 standard? It doesn't necessarily have to be in Xcode, I am comfortable using any (UNIX) IDE or build environment.

Answer 1

I've been able to solve my own question, and I thought I'd share it with those who might be struggling with this as well.

Like I suspected, the problem occurred because my GSL install (from macports) was build against the "old" STL (libstdc++). Hence, my solution was to recompile GSL against the "new" STL (libc++). This is easily done by unpacking the sources and running

./configure CC=clang CFLAGS="-stdlib=libc++" LDFLAGS="-stdlib=libc++"

I also added --disable-shared to build the static library only, and --prefix=... to set the build path. Then all what's left is to run make and make install .
