MacOS 上安装 R 包
install.packages("data.table")后面提示是否安装需要编译的版本: Do you want to install from sources the package which needs compilation?y/n 选择了 y 之后，报错
clang: error: unsupported option '-fopenmp' 网上找到的解决方法是：
- 安装 clang-omp
brew install clang-omp但是提示：
Error: No available formula with the name "clang-omp"
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
==> Searching local taps...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.- 原来是 clang-omp 迁移到了 llvm 中，遂安装 llvm
brew install llvm
ln -s /usr/local/opt/llvm/bin/clang /usr/local/bin/clang-omp- 但是还是同样的报错，观察错误提示：
clang -I/Library/Frameworks/R.framework/Resources/include -DNDEBUG -I/usr/local/include -fopenmp -fPIC -Wall -g -O2 -c assign.c -o assign.o
clang: error: unsupported option '-fopenmp'发现，执行的是 clang，而不是 clang-omp，所以在命令行执行
ln -s /usr/local/opt/llvm/bin/clang /usr/local/bin/clang
ln -s /usr/local/opt/llvm/bin/clang++ /usr/local/bin/clang++只加一个 clang 的软链接，后面会发现还会有个 clang++ 的报错，因此需要 clang++ 也要加。
2018.5.23：安装包“ddalpha”出现问题
ld: warning: directory not found for option '-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0'
ld: warning: directory not found for option '-L/usr/local/gfortran/lib'
ld: warning: directory not found for option '-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0'
ld: warning: directory not found for option '-L/usr/local/gfortran/lib'
ld: library not found for -lgfortran
clang-6.0: error: linker command failed with exit code 1 (use -v to see invocation)最后解决方法：
mkdir ~/.R
cd .R
vim MakevarsMakevars里面加上一句：
FLIBS = -L`gfortran -print-file-name=libgfortran.dylib | xargs dirname`保存，再重新在 R 中安装：install.packages("ddalpha") 即可。
