Question

我正在尝试建立我从Mercurial下载的Giraffe Deep Belief Chess Playing程序。

来自README.md：在Linux（GCC 4.9），OS X（GCC 4.9），Windows（MinGW-W64 GCC 5.1）上测试。由于libstdc ++中的正则表达式实现破坏，因此肯定不支持早于4.8的GCC版本。

这是错误：

David-Laxers-MacBook-Pro:giraffe davidlaxer$ make
g++ -Wall -Wextra -Wno-unused-function -std=gnu++11 -mtune=native -Wa,-q -ffast-math -pthread -fopenmp -DHGVERSION="\"efceca80bf74\"" -O3 -march=native -Wa,-q -I. -c backend.cpp -o obj/backend.o
/opt/local/bin/as: assembler (/opt/local/bin/clang) not installed
make: *** [obj/backend.o] Error 1

我在OS X 10.10.5上。

来自Makefile：

#CXX=g++-4.9  # I changed this - dbl
CXX=g++

# this is used to build gtb only
CC=gcc-4.9

HGVERSION:= $(shell hg parents --template '{node|short}')

CXXFLAGS_BASE = \
        -Wall -Wextra -Wno-unused-function -std=gnu++11 -mtune=native -Wa,-q -ffast-math \
        -pthread -fopenmp -DHGVERSION="\"${HGVERSION}\""

以下是我使用Brew，
