在Mac Osx El Capitan上编译代码时gcc和clang之间的冲突

时间：2017-05-09 13:29:02

标签： xcode macos gcc fortran gfortran

我正在编译需要C和Fortran的代码（wgrib）。我在我的MacOsx El Capitan上安装了Xcode 7.3.1和Xcode 7.3的相关命令行工具。 我在编译wgrib（失败）后粘贴命令行和config.log。

export CC=/usr/bin/gcc

export FC=/usr/local/bin/gfortran

sudo make wgrib
makefile:362: *** ERROR, fortran compiler (enironment vararible FC) is not recognized.  Stop.


vi config.log



 This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by libaec configure 1.0.0, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --disable-shared --prefix=/usr/local/grib2

答案 0 :(得分：0)

您正在使用clang，而不是GNU gcc，如输出所示：

/usr/bin/gcc --version
Apple LLVM version 7.3.0 (clang-703.0.31)

已知libaec与clang存在兼容性问题，而使用真实的gcc应该可以解决您的问题：

brew install gcc
export CC=gcc-9   # Use the version listed in `ls /usr/local/bin/gcc-*`, not clang gcc
export FC=gfortran
make
