Конфликт между gcc и clang при компиляции кода на Mac Osx El Capitan

Я компилировал код (wgrib), для которого нужны C и Fortran. Я установил Xcode 7.3.1 и соответствующие инструменты командной строки для Xcode 7.3 на свой MacOsx El Capitan. Я вставляю командную строку и config.log после компиляции wgrib (которая не удалась).

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

Почему вы называете этот конфликт между clang и gcc? Я нигде не вижу лязга. Что печатает /usr/local/bin/gfortran -v?   -  person Vladimir F    schedule 09.05.2017
comment
Эта ошибка не имеет ничего общего с Fortran. Сообщения об ошибках: неподдерживаемая опция «--fast-math» и неподдерживаемая опция «-fopenmp». Вам нужно будет исправить сломанный make-файл. Правильный флаг -ffast-math, а не --fast-math. Вам нужно, чтобы OpenMP работал на вашем компьютере.   -  person Dietrich Epp    schedule 09.05.2017

Проблема была фактически в OpenMP. Теперь все работает! Благодарю вас!   -  person Arianna    schedule 22.05.2017

Вы используете clang, а не GNU gcc, как указано в выводе:

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

Известно, что у libaec есть проблемы совместимости с clang, использование настоящего gcc вместо этого должно решить вашу проблему:

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