请教，avrstudio4.12怎么输出cof文件，用网上提供的方法都试过了，帮帮我！！

我用AVR-GCC，按  archeng504 阿成  提供的makefile格式，改了我的makefile，build时输出了

Build started 11.3.2006 at 17:29:28

Makefile:46: *** missing separator.  Stop.

Build failed with 1 errors and 0 warnings...

的错误提示





我改的makefile 文件如下：

另：可不可以直接利用avrstuio 自己直接生成可输出cof文件的makefile呢？？

mymach

要用外部的makefile文件，可以直接用winavr自带的工具修改

用外部makefile文件时要注意：

1.工程文件和目标文件(main函数所在的源文件)同名

2.makefile和目标文件放在同一个目录

3.如果头文件和C文件不在同一目录，需要在makefile中设置

archeng504

这一行错了

all: $(TARGET) test1.hex test1.eep test1.coff

应为

all: $(TARGET) test1.hex test1.eep coff

archeng504

winavr自带的工具修改的makefile文件，我觉的不适合在avrstuio中用！这个makefile文件要求跟程序文件放在同一个目录，编译时产生的文件都放在这个目录下，这样使到这个目录乱乱的。所以，我建议在avrstuio生成的makefile文件的基础上进行修改！！我编了一个makefile文件生成工具（不太好用），给你看下界面



他的功能很少，主要增加了C++功能

archeng504 阿成，你好，我也认为在avrstudio4.12中用winavr生成的makefile不好，你这个生成makefile的软件在这有下吗？？？

我又改了，但还是出现了

Build started 13.3.2006 at 08:19:19

Makefile:46: *** missing separator.  Stop.

的错误，救救我吧

archeng504

我分析过，这个makefile应该没有语法错误，可能是在网页中copy时把中文字符的空格也copy进去了！！

我贴一个Makefile上来，

点击此处下载 Makefile.rar

我那个软件还没有放上来，正在改进中。

我应该怎么改呀，我改了后，又出现新的错误了，

gcc plug-in: Error: Object file not found on expected location D:\WinAVR\my-work\pwm\pwm\pwm.elf

Make sure your makefile specifies the output .elf file as pwm.elf

你的MAKEFILE文件有修改依据吗，是根据什么修改的，有具体的修改方法吗？

e9f11

我再改就出现这个了

gcc plug-in: Error: Object file not found on expected location D:\WinAVR\my-work\pwm\pwm.elf

Build started 13.3.2006 at 11:53:21

环境：winavr20060125 + avrstudio4.12.462(sp1)  

步骤：

1.先用avrstudio生成内部makefile.

2.修改这个makefile，修改内容：

  1.找到这行

CFLAGS += -Wall -gdwarf-2 -DF_CPU=8000000UL  -O0 -fsigned-char

将其中的-gdwarf-2改为-gstabs，其他不变

修改后：CFLAGS += -Wall -gstabs -DF_CPU=8000000UL  -O0 -fsigned-char

  2.找到这行

all: $(TARGET) lcd1602_8bit.hex lcd1602_8bit.eep size

添加coff转换过程，在size前添加coff

修改后为：all: $(TARGET) lcd1602_8bit.hex lcd1602_8bit.eep coff size

再在这一行后添加coff转换的实现代码：

COFFCONVERT= avr-objcopy --debugging \

--change-section-address .data-0x800000 \

--change-section-address .bss-0x800000 \

--change-section-address .noinit-0x800000 \

--change-section-address .eeprom-0x810000



coff: $(PROJECT).elf

        $(COFFCONVERT) -O coff-avr $< $(PROJECT).cof

  3.找到这一行

        -rm -rf $(OBJECTS) t1captrue.elf dep/* t1captrue.hex t1captrue.eep

添加$(PROJECT).cof，目的是当执行清除命令时能把生成的.cof文件也删除。

修改后：-rm -rf $(OBJECTS) t1captrue.elf dep/* t1captrue.hex t1captrue.eep $(PROJECT).cof

3.在avrstudio中设为外部makefile，并调用刚才修改的makefile
