【问题描述】:

我已经下载了 makefile,并在 xcode 中使用 C/C++ 代码运行它。

它可以工作并输出信息(在控制台模式下),但是当我在做应用程序时(使用 GUI)它说:

**make: avr-gcc: 没有这样的文件或目录 制作:*** [main.o] 错误 1**

我是这样运行的:

snprintf(cmd, sizeof(cmd), "make -C \"%s/System/\" flash", path); 

等.. 但编译器不会生成/导出 (.o) 文件,因此链接器无法找到它们。

The makefile is:

# options for possible values)
MCU=atmega8

# id to use with programmer
# default: PROGRAMMER_MCU=$(MCU)
# In case the programer used, e.g avrdude, doesn't
# accept the same MCU name as avr-gcc (for example
# for ATmega8s, avr-gcc expects 'atmega8' and 
# avrdude requires 'm8')
PROGRAMMER_MCU=m8

# Name of our project
# (use a single word, e.g. 'myproject')
PROJECTNAME=myproject

# Source files
# List C/C++/Assembly source files:
# (list all files to compile, e.g. 'a.c b.cpp as.S'):
# Use .cc, .cpp or .C suffix for C++ files, use .S 
# (NOT .s !!!) for assembly source code files.
PRJSRC=main.c myclass.cpp lowlevelstuff.S

# additional includes (e.g. -I/path/to/mydir)
INC=-I/path/to/include

#####      AVR Dude 'writeflash' options       #####
#####  If you are using the avrdude program
#####  (http://www.bsdhome.com/avrdude/) to write
#####  to the MCU, you can set the following config
#####  options and use 'make writeflash' to program
#####  the device.


# programmer id--check the avrdude for complete list
# of available opts.  These should include stk500,
# avr910, avrisp, bsd, pony and more.  Set this to
# one of the valid "-c PROGRAMMER-ID" values 
# described in the avrdude info page.
# 
AVRDUDE_PROGRAMMERID=stk500

# port--serial or parallel port to which your 
# hardware programmer is attached

    标签: c++ c xcode makefile avr


    【解决方案1】:

    类似的错误信息

    avr-gcc: No such file or directory
    

    指出几件事中的一件

    1. 可执行文件avr-gcc 未安装(正确)

    2. 和/或 PATH 环境变量不包括保存可执行文件的目录

    3. makefile 调用不正确。

    4. 其他

    这里有一些可以尝试的方法

    当您说“下载了makefile”时,是您下载的全部内容,还是您下载了完整的软件包(avr?)如果只是makefile,您必须先下载整个软件包才能继续。

    许多软件包依赖于自动捕获或作为 env-vars 传入的设置信息来运行 make 文件。

    查看随软件分发提供的 .txt(有时是 .doc)文件。查找自述文件或安装。您可能会发现需要运行一组简单的命令来设置环境。很多时候

    ./configure
    make
    make install
    

    就是你所需要的。

    如果你的包没有类似的说明,那么你需要发现你的 avr-gcc 所在的位置并将其添加到 PATH 中,即

     find / -name 'avr-gcc*'
    

    取返回的路径,去掉结尾的/avr-gcc并将其添加到你的PATH中,即

     PATH="${PATH}:/path/to/avr-gcc-subdir"
     export PATH
     make
    

    如果这不起作用,请编辑您的问题以包含指向此软件包源代码的 URL。

    我希望这会有所帮助。

    【讨论】:

    • 问题是,如果我在控制台模式下编写代码,它可以工作,当我使用 gui 时,bot 不会:我正在运行它:snprintf(cmd, sizeof(cmd), "make - C\"%s/System/\"flash", path);等等..但是编译器会生成/导出(.o)文件..所以链接器找不到它们
    • 请编辑您的问题以包含此信息。此外,“配置”是该系统的一部分吗?您是否运行过它?如果您仍然停留在“avr-gcc:没有这样的文件或目录”,那么请查看我列表的前 3 个,其中一个就是问题所在,您需要了解如何让您的 GUI 接受设置 PATH 等。如果您学会使用正确的标签,您将在您的项目上获得更好的帮助,我认为其他 xcode 用户可能已经遇到过这个问题。祝你好运。
