这可能是一个不太可能的事情，但是有没有办法将 OS X 上 R Shiny 动态使用的 C++ 标准库从 libc++ 更改为 libstdc++ ？
提出这个问题的原因是我想尝试一下R Shiny但每当我尝试任何示例时，我的 R 就会崩溃:
> require(shiny)
Loading required package: shiny
> runExample("01_hello")
libc++abi.dylib: __cxa_guard_acquire detected deadlock
Abort trap: 6
从 R Gui 运行，我获得了更多信息(详细信息)，并且我注意到崩溃之前有一个 RcppExports.cpp 调用。我在使用 libc++(带有 C+11 的 LLVM C++ 标准库)与 libstdc++(GNU C++ 标准库)时遇到了问题before 。鉴于 Rcpp 需要 GNU 库，而 LLVM 库是 Xcode 5 中的默认库，我怀疑这就是问题所在。有没有办法更改 R Shiny 在 Mac OS X (10.9.1) 上加载的默认 C++ 库？

最佳答案
看到我遇到了完全相同的问题 - hadley 和 Joe 的评论为我在 MacOSX Mavericks 工作(很抱歉窃取答案，但我没有足够的声誉来添加评论...)
- 安装最新的 xcode
- (重新)安装 Rcpp
- 重新启动 R
关于c++ - 更改 Mac OS X 10.9.1 w/Xcode 5 上 R Shiny 使用的 C++ 标准库(__cxa_guard_acquire 检测到死锁)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21607657/
