arm-none eabi-ld:找不到-lc

Question

我正在尝试为基于XMC1100的开发板编写代码。我正在尝试这个教程：http://eleceng.dit.ie/frank/arm/BareMetalXMC2Go/index.html

我已经下载了blinky.tar.gz文件并解压缩。当我尝试"make“时，我得到这个错误:arm-none eabi-ld:找不到-lc

下面是"make“的输出

arm-none-eabi-gcc -c -mcpu=cortex-m0 -mthumb -g init.c -o init.o
arm-none-eabi-gcc -c -mcpu=cortex-m0 -mthumb -g main.c -o main.o
arm-none-eabi-ld init.o main.o  -L /usr/lib/gcc/arm-none-eabi/4.8.2/armv6-m -T linker_script.ld -lc --cref -Map main.map -nostartfiles -o main.elf
arm-none-eabi-ld: cannot find -lc
make: *** [main.elf] Error 1

我使用的是Linux Mint 17 Qiana

我错过了什么？

这是我的makefile：

LIBSPEC=-L /usr/lib/gcc/arm-none-eabi/4.8.2/armv6-m

# Specify the compiler to use
CC=arm-none-eabi-gcc
# Specify the assembler to use
AS=arm-none-eabi-as
# Specity the linker to use
LD=arm-none-eabi-ld

CCFLAGS=-mcpu=cortex-m0 -mthumb -g

# List the object files involved in this project
OBJS=   init.o \
        main.o 

# The default 'target' (output) is main.elf and it depends on the object files being there.
# These object files are linked together to create main.elf
main.elf : $(OBJS)
    $(LD) $(OBJS) $(LIBSPEC) -T linker_script.ld -lc --cref -Map main.map -nostartfiles -o main.elf
    arm-none-eabi-objcopy -O binary main.elf main.bin
    objcopy -O ihex main.elf main.hex
    @echo "done"

# The object file main.o depends on main.c.  main.c is compiled to make main.o
main.o: main.c
    $(CC) -c $(CCFLAGS) main.c -o main.o


init.o: init.c
    $(CC) -c $(CCFLAGS) init.c -o init.o

# if someone types in 'make clean' then remove all object files and executables
# associated wit this project
clean: 
    rm $(OBJS) 
    rm main.elf
    rm main.bin

我遇到了同样的问题，sudo apt-get install libnewlib-arm-none-eabi帮助了我。

Answer 2

在尝试运行构建时，我得到了以下信息：

/usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/bin/ld: cannot find -lstdc++

我已经使用sudo apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi make dfu-util在Ubuntu上安装了这些包，但似乎还需要一个(至少对我的系统是这样)。在安装libstdc++-arm-none-eabi-newlib之后，它能够找到正确的文件。

以下是我的系统上该软件包中包含的文件：

$ apt-file show libstdc++-arm-none-eabi-newlib | grep -e "stdc++.a$"
