在 Ubuntu 16.04 上找不到 printf.c

Question

我最近切换到Ubuntu 16.04。我在 Ubuntu 上使用 vscode 作为 IDE。我配置了其他语言，但我无法为C/C++ 配置。我创建了c_cpp_properties.json, launch.json & tasks.json。当我开始编译任何给定的代码时，当拟合函数如printf 或malloc 时会出错。 错误信息：

无法打开“printf.c”：找不到文件 (file:///build/glibc-Cl5G7W/glibc-2.23/stdio-common/printf.c)。

我该如何解决这个问题？

很遗憾，Debian 和 Ubuntu 并未将源代码作为调试包的一部分提供。据我所知，也没有计划将资源作为dbgsym packages 的一部分发送。

相比之下，Fedora 及其下游发行版拥有广泛的基础设施来准备可用的源文件以进行调试。这样做并不完全是微不足道的，因为它需要重写 DWARF 数据中的文件路径，从构建树位置到安装位置。但它对调试非常有帮助，并为整个发行版提供了很好的免费软件风格。
