如何禁用GCC警告作为源代码开发人员被视为错误的大量冗余解释。现在，我想知道是否有办法在不接触源代码(包括构建工具配置文件(的情况下禁用它们，即让编译继续忽略警告。根据我对 GCC 文档在请求或抑制警告选项中的理解，如果指定用于./configure和make，CXXFLAGS="-w"应该足够了，例如，CXXFLAGS="-w" ./configure && make 。
备注：我知道违背开发人员的意图编译程序不是一个好主意，并且传达问题并一起修复它总是更好的选择，如果不是唯一的话。
背景(请阅读整个问题，尤其是上面和下面的评论，我不是在寻找以下问题的修复程序！ 我正在尝试在具有 armv7 架构的 Synology DSM 5.0 上的 Debian 7.6 chroot 中编译 QEMU Git 标签 v2.1.0 并获得

尝试了一些选项，现在我只想知道这是否可能，以便在 GNU 构建工具中实现更好的内部。我非常确定构建结果即使不是无法使用，也至少是不可靠的。
顺便说一句：如果您通过搜索引擎找到此问题，并且在使用 QEMU 时遇到相同或类似的问题，请参阅 v2.1.0 的构建由于未声明__NR_select而在 armv7l 上失败。
您对-w选项的看法是正确的，确保它传播到任何地方的最简单方法是将其放在CC变量中：CC="gcc -w" ./configure ...
但是，如果他们专门将此警告作为错误打开，那么我认为您不应该尝试禁用它。在这种情况下，代码显然是为了使此警告不可能实现，并且很可能您的工具链中存在严重错误(例如，整数类型定义错误，因此它们期望的类型与指针大小相同(。您应该尝试跟踪此问题，否则您只会浪费时间在运行时崩溃的损坏版本上。为什么不查看警告消息引用的一些源代码行，看看实际发生了什么？
