为什么 GNU make 进程挂起？

Question

TL;DR:

全新Windows10 安装，我安装了ARM DS-5 v5.26.2 开发工具。我正在使用它的 make.exe 来构建我们的项目，无论是从 Cygwin 命令行还是从 Eclipse IDE 的构建设置。

我们的 Makefile 包含以下行：

uname_result := $(shell uname -s)

但是每当 make 到达这条线时，它就会卡住。这发生在 bash 终端以及 Window 的命令提示符上。

更新 3：

经过更多故障排除后，问题似乎出在 DS-5 的 make 实用程序本身。我将 make 添加到我的 Cygwin 安装中，并使用了那个，现在我的构建运行 OK。

现在的问题是为什么 ARM 的版本不能在我的 Win 10 机器上运行，而它以前在 Win 7 上运行良好。

长版：

在工作电脑上使用 Windows 7 两年后，我刚刚在工作电脑上全新安装了 Windows 10。在过去的两天里，我正在经历重新安装我们的工具并恢复体形的过程。不幸的是，我现在受困于 make 让我头疼。

我们使用 ARM 的 DS-5 工具集开发嵌入式固件。该项目是一个 Makefile 项目，因此我们不使用内置的 Eclipse 构建器。为了在 Eclipse 环境之外构建项目，我安装了 Cygwin 以方便使用 bash CLI。 make 和 clang 都是 DS-5 安装的一部分。

当我在项目的 Makefile 表单 CLI 上运行 make 时，执行会无限期地卡住。

[...去除一个长篇大论继问题揭露过程...]

追查问题根源，发现问题出在这一行：

uname_result := $(shell uname -s 2>NUL)

为了简化，我验证了问题出在shell命令本身。我用以下命令做了一个非常简单的 Makefile，但也卡住了：

uname_result := $(shell ls)

当使用 make -d 处理 makefile 时，当它到达该行时，我得到以下信息：

CreateProcess(C:\cygwin64\bin\ls.exe,ls,...)
Main thread handle = 000000000000009C

为什么make不能执行shell命令？在迁移之前，这个完全相同的脚本曾经工作得很好。

更新 1 及更多信息：

我的系统上只有一个make.exe，放在C:\DS-5_v5.26.2\bin。

我创建了一个简化的 makefile，Makefile.tmp:

.PHONY: help
help:
    echo ====================== TESTING ======================
    uname_result := $(shell ls)

我从 Cygwin 的 bash CLI 处理这个 makefile:

$ /cygdrive/c/DS-5_v5.26.2/bin/make -d -f Makefile.tmp help

我在 return:

因此，如您所见，它既不执行 echo 命令也不执行 ls 命令。如果我注释掉 shell 命令，我会看到 TESTING 消息回显到终端。

显然，DS-5 的 make.exe 是为 Windows 打造的。从 Cygwin bash 调用它应该有问题吗？如果是这样，为什么它在 Win 7 机器上运行良好？

更新 2 及更多信息：

我重复了测试，这次运行ning 来自 Windows' CMD 提示。我用 dir 命令替换了 bshell 行中的 ls 命令。令人惊讶的是，同样的行为也在 CMD 上发生了！

所以，显然，问题是 make 的 shell 函数调用。

Answer 1

在与 ARM 支持联系后，我得到了以下回复：

With regards to the problem you are seeing this is a known issue with GNU 
make version 4.1 supplied by ARM with DS5.  This version of make was shipped 
with DS5 versions 5.23 to 5.26. DS5-5.22 used make 3.81, and DS5-5.27 and 
later have used make 4.2 - neither of which suffer from this defect.

There are three possible workarounds in your case:
1 - Avoid using the "shell" command in your make script - this is probably 
not ideal!
2 - Upgrade your DS-5 version to 5.27 or later - this may or may not be an 
option for you.
3 - Download[*] a different version of GNU make and use it in place of the 
version 3.81 that was supplied with your current version of DS-5.

[*] - Although make is freely available under GPL, unfortunately there are 
legal implications involved with its redistribution which is why I can't 
simply email you an alternative version of make.

感谢 ARM 的 Alex 对此的支持。
