制作，错误127 [英] Make, error 127

问题描述

我想首先警告你，我的这方面的知识很差，我想，请不要太过于苛刻地对待我。

所以，在这个学期里，我得到了这个新的主题，我们可以与Discovery STM32 F4一起工作，而且我们仍处于设置阶段。但是我在开始时遇到了这个问题。

当我尝试编译这个blink代码时，我得到这个错误：
错误127

因此，到目前为止，我们使用这个快捷命令make来编译代码，并且我们给出了设置它的指令，如下图所示：
设置

任何人都可以看到这里有什么问题吗？

解决方案

错误127 表示以下两种情况之一：

未找到

1. 文件：您使用的路径不正确。仔细检查程序是否在你的 $ PATH 中，或者在这种情况下，相对路径是正确的 - 记住随机终端的当前工作目录可能不是对于您使用的IDE也是如此。取而代之的是使用绝对路径可能更好。
找不到ldso：您正在使用预编译的二进制文件，并且它想要一个不在系统上的解释器。也许你使用的是x86_64（64位）发行版，但预构建的是x86（32位）。您可以通过打开终端并尝试直接执行它来确定这是否是答案。或者通过在 / bin / sh （以获得默认/本机格式）和编译器上运行 file -L 本身（看看它是什么格式）。如果问题是（2），那么你可以用几个diff来解决它。

方式：

1. 得到一个更好的二进制文件。与提供工具链的供应商交谈，并要求他们提供不吸引人员。


2. 查看您的发行版是否可以安装multilib文件集。大多数x86_64 64位发行版允许您并行安装x86 32位库。
   
3. 使用类似于 crosstool-ng 。


4. 你可以在x86_64& x86安装，但看起来有点激烈;）。

I'd like to warn you first that my knowledge on this subject is very poor, I guess, so don't go too hard on me, please.

So, in this semester I got this new subject where we get to work with Discovery STM32 F4, and we are still in the phase of setting it up. But I have this problem in the beginning.

When I try to compile this "blink" code I get this error: Error 127

So, as I got it so far, we are using this shortcut command "make" to compile code, and we were given instruction to set it up as it's shown in images below: setup

Can anyone see what's the problem here?

解决方案

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).
