根据valgrind官方文档，不支持QNX。 然而，我看到了一些关于在 QNX 上使用 valgrind 的问题。 问题1 问题2。 这让我很困惑。是否可以在 QNX 上运行 Valgrind？ 如果可以的话，如何实现呢？ 也许编译一个与 QNX 平台兼容的可执行文件？或者有没有办法下载正确的文件？
我在 QNX 社区找到了 Valgrind 项目。 我下载了软件包。 但是，它不包含我需要的有关arm64/aarch64架构的文件。
您可能需要下载源代码（从这里https://community.qnx.com/sf/scm/do/listRepositories/projects.valgrind/scm）并构建它。
看起来它已经维护了 7 年了（Valgrind 3.11），所以我认为让它构建和工作将是一项巨大的努力，除非 QNX 和工具链同时没有太大变化。
我们正在使用 QNX SDP 7.1.0，并使用提供的 valgrind 我们尝试检查示例代码的内存泄漏，但是我们面临以下问题。
ARM64 front end: load_store
disInstr(arm64): unhandled instruction 0x88E1FC02
disInstr(arm64): 1000'1000 1110'0001 1111'1100 0000'0010
==151577== valgrind: Unrecognised instruction at address 0x17e48.
==151577== at 0x17E48: ??? (in /proc/boot/ldqnx-64.so.2)
==151577== Your program just tried to execute an instruction that Valgrind
==151577== did not recognise. There are two possible reasons for this.
==151577== 1. Your program has a bug and erroneously jumped to a non-code
==151577== location. If you are running Memcheck and you just saw a
==151577== warning about a bad jump, it's probably your program's fault.
==151577== 2. The instruction is legitimate but Valgrind doesn't handle it,
==151577== i.e. it's Valgrind's fault. If you think this is the case or
==151577== you are not sure, please let us know and we'll try to fix it.
==151577== Either way, Valgrind will now raise a SIGILL signal which will
==151577== probably kill your program.

We also tried to cross compile Valgrind 3.23.0 for qnx platform, and we are unable to configure because of the following error
checking for a supported OS... no (nto-qnx)
configure: error: Valgrind is operating system specific. Sorry.
How can we cross compile for QNX platform?
