Valgrind:致命错误:memcheck.h:没有那个文件或目录 [英] Valgrind: fatal error: memcheck.h: No such file or directory

问题描述

我们正试图在 Valgrind 报告的 C++ 项目中追踪条件跳转或移动取决于未初始化的值.发现中提供的地址并没有真正的帮助，因为它指向 GCC 扩展程序集块的末尾，而不是导致问题的实际变量.

We are trying to track down a Conditional jump or move depends on uninitialised value in a C++ project reported by Valgrind. The address provided in the finding is not really helpful because it points to the end of a GCC extended assembly block, and not the actual variable causing the trouble.

根据 Valgrind's 用 Valgrind 消除未定义的值，最简单的方法，我们可以在包含 后使用 VALGRIND_CHECK_MEM_IS_DEFINED 或 VALGRIND_CHECK_VALUE_IS_DEFINED.此外，这些宏或函数显然记录在头文件中(绝对没有针对它们的手册页).

According to the Valgrind's Eliminating undefined values with Valgrind, the easy way, we can use VALGRIND_CHECK_MEM_IS_DEFINED or VALGRIND_CHECK_VALUE_IS_DEFINED after including <memcheck.h>. Additionally, those macros or functions are apparently documented in the header file (there is definitely no man page for them).

但是，当我包含 或 时，它会导致:

However, when I include <memcheck.h> or <valgrind/memcheck.h>, it results in:

致命错误:memcheck.h:没有那个文件或目录

fatal error: memcheck.h: No such file or directory

基于 Stack Overflow 的 如何找到哪个 rpm 包提供了我正在寻找的文件?，我执行了一个 RPM 文件搜索，但是它为 memcheck.h 返回 0 个命中.

Based on Stack Overflow's How do I find which rpm package supplies a file I'm looking for?, I performed a RPM file search, but its returning 0 hits for memcheck.h.

问题

1. 博客文章有点过时了.信息是否仍然适用?

1. The blog article is a bit dated. Does the information still apply?

如果信息准确，那么我在哪里可以找到memcheck.h?

If the information is accurate, then where do I find memcheck.h?

推荐答案

您必须安装包含 memcheck.h 的 RPM valgrind-devel.

You have to install the RPM valgrind-devel which contains memcheck.h.

*-devel 包通常位于可选"存储库中(例如 RHEL 6 上的 rhel-x86_64-server-optional-6).此外，您可以在 Google 上找到 RPM，下载并自行安装.无论采用哪种方法，memcheck.h 通常在安装后放置在 /usr/include/valgrind 中.

The *-devel packages are typically located in the "optional" repositories (e.g. rhel-x86_64-server-optional-6 on RHEL 6). Also, you can find the RPM on Google, download it, and install it on its own. With either approach, memcheck.h is typically placed in /usr/include/valgrind once installed.
