OSX上的makefile路径问题

makefile

OSX上的makefile路径问题,makefile,Makefile,好的，我想我会尝试最后一次更新，看看它是否能让我有所收获。我创建了一个非常小的测试用例。这不应该构建任何东西，它只是测试路径设置。我还设置了路径，因此没有空格。这是我能想到的最小、最简单的测试用例 此生成文件将设置路径，回显路径，使用指定的完整路径运行avr gcc-v，然后在不使用指定的完整路径的情况下尝试运行它。在第二次尝试时，它应该在路径中找到avr gcc，但没有 makefile TOOLCHAIN := /Users/justinzaun/Desktop/AVRBuilder.app

然后它找到了，但这似乎不是正确的方法。例如，它试图将系统

而不是正确路径中的系统

update-为了确保这一点，我还添加了
ls

您的问题不是
make
未能找到
avr gcc
。您的问题在这一行：


$(CC) $(CFLAGS) -mmcu=$(MCU) -c $(input) -o $(output)


由于未定义
$（输入）
和
$（输出）
，因此您的
avr gcc
命令行不完整。请尝试将该行改为：


$(CC) $(CFLAGS) -mmcu=$(MCU) -c $< -o $@



$（CC）$（CFLAGS）-mmcu=$（MCU）-c$<-o$@



$我猜您正在使用OSX。找出一个优雅的解决方案可能需要几次迭代

同时，试一下这个乱七八糟的方法，告诉我们结果：


CC=`avr-gcc`


问题是make无法找到avr gcc，这是由于
PATH=
行中的
\
造成的


$ mkdir /tmp/foo\ bar
$ cd /tmp/foo\ bar
$ (echo "#! /bin/sh"; echo "echo this got run") > execable
$ chmod +x execable
$ mkdir /tmp/tstmake; cd /tmp/tstmake


（现在制作一个包含如图所示内容的Makefile）


更新：这不是唯一的问题，至少在我使用MBP模拟问题时是如此。其余两项是：


    

  • CPATH
    还需要删除反斜杠（这是关于这些设置的一般规则：=设置）
    • 

  • CPATH
    需要通过添加行显式地
    export
    ed
    
出口CPATH
    • 


到
Makefile


（有时需要反斜杠的原因与字符串被明确传递到shell的次数有关：当字符串在
$（CC）
中时需要反斜杠一次，但当它是环境变量或
$（PATH）
的一部分时需要反斜杠零次）
如果要更新PATH变量，请执行以下操作：


export PATH=$(shell echo $${PATH}):<paths to add>


生成文件：


export PATH=$(shell echo $${PATH}):c:.
all:
    @luckyme.sh


make的输出：


~$ make
Hello Lucky Me ! 



我在OSX和Linux上尝试了您的示例，得到了与您相同的结果。我不太明白为什么这不起作用（我很想知道），但我确实有两个解决办法可能会有所帮助

导出SHELL

不要在Makefile中设置路径，而是像这样覆盖SHELL：


export SHELL=/Users/whatever/avr-dir/wrapper


以下是该包装器的可能版本：


#!/bin/bash
PATH="/Users/whatever/avr-dir:${PATH}"
/bin/bash "$@"


Make将调用此包装器来运行yoru配方的每一行。这有点难看，但它确实在OSX上对我有效

修复make之外的路径。也许创建一个脚本，每次登录时运行一次，修复shell中的路径，或者创建一个小脚本（我通常称之为
mk
），修复路径，然后调用make传递任何参数。这是一个exmaple：


#!/bin/bash
PATH="/Users/whatever/avr-dir:${PATH}" exec make "$@"



我知道你要求一个Makefile解决方案，但我想我还是会提到这个选项。这只是我的观点，但路径之类的东西往往是特定于机器的（而不是特定于项目的），我更喜欢将它们与源代码分开。
鉴于此页面没有正确的答案，我将链接到此页面，它会：



无论出于何种原因，OSX都不会导出路径，除非您也设置了SHELL变量

因此：


…行得通。
我最近才遇到这个问题。正如其他评论所指出的，MacOS附带的
make
版本存在一些问题。构建（如上面@MadScientist建议的）或GNU自制。在我的系统上安装的
make
版本是3.81，并且显示出相同的问题。自制软件（4.3版）提供的版本正常工作。
生成文件可能出错，但这不是错误的原因。我发布了一个更新的makefile和错误消息。这仍然归结为路径中找不到avr gcc，我可以看到它在那里。如果问题是路径中找不到avr gcc，那么错误将是“未找到命令”，而不是“没有这样的文件或目录”，make的退出代码将是127，而不是1。-我将研究其他问题，只是看起来有些奇怪。main.c也在那里。我真的认为这仍然是一个路径问题，请参阅我的更新问题。如果我只是遗漏了一些东西，而这不是路径问题，那么我真的不知道它是什么。我已经将路径行设置为
path:=/Users/justinzaun/Library/Developer/Xcode/DerivedData/AVR_Builder-gxiykwiwjywvoagykxvmotvncbyd/Build/Products/Debug/AVR Builder.app/Contents/Resources/avrchain/bin:$（路径）
但我仍然得到
make:avr gcc:没有这样的文件或目录
。我正在添加ls命令的输出，这样我就知道我没有发疯。当您设置好手动调用
avr gcc
时，
which
（或
type-p
）会说什么？例如，在我的MBP
上，哪个gcc<
