我试图安装托克。但是在制作文件时我遇到了以下问题

有人可以建议如何解决这个问题

从https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853685，Debian 存储库中的 torcs 版本 1.3.7+dfsg-4 包含修复您遇到的构建错误的补丁，方法是将有问题的行中的指针更改为指向 a nullptr。

-   const char* error = '\0';
+   const char* error = nullptr;

完整的补丁文件位于https://sources.debian.org/patches/torcs/1.3.7+dfsg-4/gcc7.patch/它引入的修复是平台中立的。或者，您可以-fpermissive按照日志提示进行编译。
