不同的语言执行不同的代码编译命令。

代码编译成功后进行子程序的判断运行。

def compile(solution_id, language, program_info, dblock):    low_level()    '''将程序编译成可执行文件'''    language = language.lower()    language_to_cmd={        "c": "gcc",        "c++": "g++",        "python": "python2",    }    if language in language_to_cmd.keys():        language = language_to_cmd[language]    dir_work = os.path.join(config.work_dir, str(solution_id))    build_cmd = {        "gcc":        "gcc main.c -o main",        #"gcc main.c -o main -Wall -lm -O2 -std=c99 --static -DONLINE_JUDGE",        "g++":         #"g++ main.cpp -O2 -Wall -lm --static -DONLINE_JUDGE -o main",        "g++ main.cpp -o main",        "java": "javac Main.java",        "ruby": "reek main.rb",        "perl": "perl -c main.pl",        "pascal": 'fpc main.pas -O2 -Co -Ct -Ci',        "go": '/opt/golang/bin/go build -ldflags "-s -w"  main.go',        "lua": 'luac -o main main.lua',        "python2": 'python2 -m py_compile main.py',        "python3": 'python3 -m py_compile main.py',        "haskell": "ghc -o main main.hs",    }    if language not in build_cmd.keys():        return False    p = subprocess.Popen(        build_cmd[language],        shell=True,        cwd=dir_work,        stdout=subprocess.PIPE,        stderr=subprocess.PIPE)    out, err = p.communicate()  # 获取编译错误信息    logging.info("complie info (empty means OK): " + out+err)    err_txt_path = os.path.join(config.work_dir, str(solution_id), 'error.txt')    f = file(err_txt_path, 'w')    f.write(err)    f.write(out)    f.close()    if p.returncode == 0:  # 返回值为0,编译成功        return True    program_info["compile_info"] = err + out    #dblock.acquire()    #update_compile_info(solution_id, err + out)  # 编译失败,更新题目的编译错误信息    #dblock.release()    return False
