文件格式无法识别;作为链接描述文件处理 - 为arm处理器编译c代码

标签： c linux arm

我正在努力编写一个arm设备的演示程序。

文档不存在，我更习惯于Windows环境。

我已经安装并试用了Ubuntu 14和13.10，但两者都存在同样的问题。两者都是32位。

makefile是这样的：

#
# program makefile for the POS Application
#

# build on arm-linux platform
ARCH    = /opt/gcc-4.0.2-glibc-2.3.5/arm-unknown-linux-gnu/bin/arm-unknown-linux-gnu-

# programs we use...
CP  = cp -f
MKDIR   = mkdir -p
RM  = rm -f
RMDIR   = rm -rf
TAR = tar -zcf
STRIP   = $(ARCH)strip
RANLIB  = $(ARCH)ranlib

# compiler names:
CC      = $(ARCH)gcc
CXX     = $(ARCH)g++

# flags for C/C++ compiler:
INCFLAG     = -I../include -I../sdk/include
OPTIM       = -Wall -O2 -Wunused
CFLAGS      = $(OPTIM)
CXXFLAGS    = $(OPTIM) -Wno-non-virtual-dtor

# libraries to link with:
LD_LIBS     = -ldl -lrt
LD_SDK      = -L../sdk -lkfsdk

LDFLAGS     = $(LD_LIBS) $(LD_SDK)

# Which targets should be built?
TARGET  = demo_app
#RELEASEDIR = ../release

# Be quiet when building...
#.SILENT:

#
# Files for this directory...
#
SRCDIR  = ../src

PATH1       = $(SRCDIR)/gui/
PATH2       = $(SRCDIR)/platform/

COBJECT     = \
        $(addprefix $(PATH1), $(addsuffix .o, $(basename $(notdir $(wildcard $(PATH1)*.c))))) \
        $(addprefix $(PATH2), $(addsuffix .o, $(basename $(notdir $(wildcard $(PATH2)*.c))))) \

CPPOBJECT   = \
        $(addprefix $(PATH1), $(addsuffix .o, $(basename $(notdir $(wildcard $(PATH1)*.cxx))))) \
        $(addprefix $(PATH2), $(addsuffix .o, $(basename $(notdir $(wildcard $(PATH2)*.cxx))))) \

#CFILES     = $(wildcard *.c)
#COBJECT    = $(patsubst %.c, %.o, $(CFILES))
#CPPFILES   = $(wildcard *.cxx)
#CPPOBJECT  = $(patsubst %.cxx, %.o, $(CPPFILES))

#
# Make everything...
#
all:    $(TARGET)
#   $(CP) $(TARGET) $(RELEASEDIR)
    @echo "All files have been made"
    @echo "            ************************************"
    @echo "            *                                  *"
    @echo "            *       POS APPLICATION      *"
    @echo "            *                                  *"
    @echo "            ************************************"
    @echo "succeed"

$(TARGET):  $(COBJECT) $(CPPOBJECT)
    @echo Linking $(TARGET)...
    $(CC) -o $@ $^ $(CFLAGS) $(LDFLAGS)
#   $(CXX) -o $@ $^ $(CXXFLAGS) $(LDFLAGS)

%.o:%.c
    @echo Compiling $<...
    $(CC) $(CFLAGS) $(INCFLAG) -o $@ -c $<

%.o:%.cxx
    @echo Compiling $<...
    $(CXX) $(CXXFLAGS) $(INCFLAG) -o $@ -c $<

#
# Clean old files...
#
clean:
    $(RM) *.o
    $(RM) $(PATH1)*.o
    $(RM) $(PATH2)*.o
    $(RM) $(TARGET)

#
# End of "$Id: Makefile 2011-01-24 08:21 $".
#
# DO NOT DELETE

我已经运行make clean，然后制作并获得以下消息：

Compiling ../src/platform/main.c...
/opt/gcc-4.0.2-glibc-2.3.5/arm-unknown-linux-gnu/bin/arm-unknown-linux-gnu-gcc -Wall -O2 -Wunused -I../include -I../sdk/include -o ../src/platform/main.o -c ../src/platform/main.c

/opt/gcc-4.0.2-glibc-2.3.5/arm-unknown-linux-gnu/bin/ld:/opt/gcc-4.0.2-glibc-2.3.5/arm-unknown-linux-gnu/bin/../lib/gcc/arm-unknown-linux-gnu/4.0.2/../../../../arm-unknown-linux-gnu/lib/libdl.so:1: parse error
collect2: ld return 1 exit status.

从我所做的谷歌搜索，将文件链接在一起似乎是一个问题，但我不知道为什么和出了什么问题。

我尝试过apt-get install gcc-arm-linux-gnueabi

/opt/gcc-4.0.2-glibc-2.3.5目录和子目录附带为设备提供的所谓SDK。

关于如何使其发挥作用的任何想法？

谢谢

编辑1：

如果我在libdl.so上执行了更多操作，则会显示libdl.s0.2。如果我更多该文件，它会给出libdl-2.3.5.so。最后，如果我做了readelf -h libdl-2.3.5.so该文件，我得到：

ELF

我做file libdl-2.3.5.so我得到了：

由于篇幅很长，我在这里编辑了。

这是一个示例make文件，
它包括依赖文件的创建和使用 包含头文件。 它使用'sed'生成依赖文件。 一般来说，它希望所有文件都在 本地目录，因此您需要对其进行修改 您的多个源文件目录等

首先道歉，需要很长时间才能恢复原状，感冒了并且躺在床上。

我终于弄清楚发生了什么，事实证明它很简单，就像往常一样。

arm设备的SDK附带了放在/ opt下的GCC。事实证明，由于某种未知的原因，我所拥有的副本已经解开了，但在/opt/gcc-4.0.2-glibc-2.3.5/arm-unknown-linux-gnu/arm下丢失了所有链接-unknown-linux-gnu / lib目录。

感谢undur_gongor，你的评论使我更接近这些文件，我设法找到原始的.tar.bz2文件，解压缩到正确的目录和所有链接，并且它编译正常。
