Question

10.12.1全新安装，升级到10.12.3。

我做了brew install unixodbc。

然后我尝试了R CMD INSTALL RODBC_1.3-14.tar.gz 有错误：

checking for gcc... /usr/local/opt/llvm/bin/clang -fopenmp checking whether the C compiler works... no configure: error: in `/private/var/folders/7f/3n9kqyy13glcwlrx7h8cb5dc0000gn/T/RtmpYQnA2y/R.INSTALL354a771740af/RODBC': configure: error: C compiler cannot create executables See `config.log' for more details ERROR: configuration failed for package ‘RODBC’

然后我解压缩RODBC并尝试./configure并在日志中收到以下错误消息：

configure:2690: /usr/local/opt/llvm/bin/clang -fopenmp -v >&5 clang version 3.9.1 (tags/RELEASE_391/final) Target: x86_64-apple-darwin16.4.0 Thread model: posix InstalledDir: /usr/local/opt/llvm/bin configure:2701: $? = 0 configure:2690: /usr/local/opt/llvm/bin/clang -fopenmp -V >&5 clang: error: argument to '-V' is missing (expected 1 value) clang: error: no input files configure:2701: $? = 1 configure:2690: /usr/local/opt/llvm/bin/clang -fopenmp -qversion >&5 clang: error: unknown argument: '-qversion' clang: error: no input files configure:2701: $? = 1 configure:2721: checking whether the C compiler works configure:2743: /usr/local/opt/llvm/bin/clang -fopenmp -Wall -mtune=core2 -g -O2 -I/usr/local/opt/llvm/include -I. conftest.c >&5 ld: library not found for -lomp clang: error: linker command failed with exit code 1 (use -v to see invocation) configure:2747: $? = 1 configure:2785: result: no

我遇到了同样的问题对我来说，问题是R安装程序依赖于OS X附带的clang编译器（Sierra，10.12.4），does not support openmp。

我也无法获得指定configure工作的不同编译器的常用方法（例如示例here），因为事实证明，RODBC的配置脚本很难 - 编码为使用R安装指定的编译器和lib / include路径，这些路径描述为here。

我能够通过编辑~/.R/Makevars来指向我通过macports（gcc）安装的sudo port install gcc6版本来解决问题，原因如下：

CC=/opt/local/bin/gcc-mp-6 -fopenmp
CXX=/opt/local/bin/g++-mp-6
LDFLAGS=-L/opt/local/lib -L/usr/local/opt/llvm/lib
CPPFLAGS=-I/opt/local/include -I/usr/local/opt/llvm/include

然后正常安装过程（R CMD INSTALL ./RODBC_1.3-15.tar.gz）按预期工作。

安装RODBC Mac OS Sierra 10.12.3
