问题描述

我想在我的一个函数中使用标准的 c 函数

I want to use standard c function in one of my function

void print(const char* format,...) {    
    char buffer[256];
    va_list args;
    va_start (args, format);
    vsnprintf (buffer,256,format, args);
    va_end (args);
    sendString(buffer);
}

错误来了

我的makefile是这个

My makefile is this 

TOOLCHAIN=arm-none-eabi-

all: Serial.o irq.o lowlevel.o main.o startup.o 

    $(TOOLCHAIN)ld  -o check.elf -T /home/sanju/Arm/check/other/ROM.ld Serial.o irq.o

    $(TOOLCHAIN)gcc $(CCFLAGS) -I$(INCLUDE) -c $< 

startup.o : startup.S 

    $(TOOLCHAIN)as $(ASFLAGS) -o startup.o $< 




.PHONY: clean 

clean : 

    rm -rf *.o  *.elf *.hex *.o *.bin

在目标中，所有链接都失败了.我已经用 arm-elf 工具链尝试过这个例子，我也遇到了一些错误.我用谷歌搜索了很多，但没有找到任何解决方案.

In the target all it fails in linking. I have tried the example with arm-elf toolchain there also i am getting some errors.I have googled a lot for it but did not find any solution for it.

推荐答案

尝试使用 gcc 作为 ld 前端.更改:

Try using gcc as ld frontend. Change:

$(TOOLCHAIN)ld  -o check.elf [...]

进入

$(TOOLCHAIN)gcc  -o check.elf [...]

GCC 知道在调用 ld 时添加一些必要的选项.

GCC knows to add some necessary options when invoking ld.
