Question

我在ubuntu上安装4suite.xml时遇到此错误。试图在我的ubuntu上安装harpia，但我的系统中缺少几个包，所以在获取那些缺少的依赖项的过程中，我坚持这一点。

cc1: some warnings being treated as errors

你可以帮我解决这个问题吗？

Answer 1

尝试使用以下代码可能会有所帮助：

fprintf(fp, "%s", PyString_AS_STRING(repr));

线索来自fprintf, error: format not a string literal and no format arguments [-Werror=format-security]和How to fix this compiler error 'format not a string literal and no format arguments'以及deploying python codes

中的类似情况

Answer 2

对我来说一个快速而肮脏的解决方法是将 CFLAGS 设置为使用 -Wno-error=format-security 覆盖 -Werror=format-security（CenTOS 上的 python 2）：

wget  https://files.pythonhosted.org/packages/0e/ae/3c5b4fffb12be7c3a80c99475853349e1cf8477f99051921ea06fbf5e3b9/4Suite-XML-1.0.2.tar.gz
tar -xvf 4Suite-XML-1.0.2.tar.gz
export CFLAGS=" -Wno-error=format-security" # no error will be generated, you know what you do
python2  ./setup.py install # 4Suite-XML compilation works without error

错误：格式不是字符串文字而没有格式参数[-Werror = format-security]
