这是XML的

这是原来Makefile的
simple_quoter_server: $(simple_quoter_server_objects)
        g++ -L/usr/local/lib -I/usr/local/include \
        -o sqs $(simple_quoter_server_objects) \
        -lexpat -lpthread

改成交叉编译
simple_quoter_server: $(simple_quoter_server_objects)
        arm-linux-gcc-4.4.3 -L/usr/local/lib -I/usr/local/include \
        -o sqs $(simple_quoter_server_objects) \
        -lexpat -lpthread

make 后出现错吴
simple_quoter_server.o: could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make: *** [simple_quoter_server] Error 1

file信息
# file simple_quoter_server.o
simple_quoter_server.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

小白求解答

先make  clean一下，可能目录下还留有x86的.o文件

试了，我确定没有 .o文件 除非有隐藏的

simple_quoter_server: $(simple_quoter_server_objects)
        arm-linux-gcc-4.4.3 -L/usr/local/lib -I/usr/local/include \
        -o sqs $(simple_quoter_server_objects) \
        -lexpat -lpthread

这只是说明sqs执行档是用交叉编译器链接生成的，但用来链接的object文件($(simple_quoter_server_objects)所指向的内容)还是按照原来的规则编译的。

好高深， 是不是Makefile文件哪里写错了？
你看下
# Makefile for XML stuff


all : simple_quoter_server simple_quoter_client

xmlrpc_objects = reply.o request.o server.o client.o \
    node.o socket.o server_socket.o client_socket.o

base64_objects = b64.o

simple_quoter_server_objects = simple_quoter_server.o \
                               $(xmlrpc_objects) \
                               $(base64_objects)

simple_quoter_client_objects = simple_quoter_client.o \
                               $(xmlrpc_objects) \
                               $(base64_objects)


CXXFLAGS= -g -I/usr/local/include


simple_quoter_server: $(simple_quoter_server_objects)
    arm-linux-gcc -L/usr/local/lib -I/usr/local/include \
    -o sqs $(simple_quoter_server_objects) \
    -lexpat -lpthread

simple_quoter_client: $(simple_quoter_client_objects)
    arm-linux-gcc -L/usr/local/lib -I/usr/local/include \
    -o sqc $(simple_quoter_client_objects) \
    -lexpat -lpthread


simple_quoter_server.o : simple_quoter_server.cpp
simple_quoter_client.o : simple_quoter_client.cpp
reply.o : reply.cpp
request.o : request.cpp
node.o : node.cpp
socket.o : socket.cpp
server_socket.o : server_socket.cpp
client_socket.o : client_socket.cpp
b64.o : b64.c


clean :
    rm -f *.o sqs sqc

看起来你需要
1. 在Makefile里加上"CXX=arm-linux-gcc-4.4.3"和"LD=$(CXX)"用来指定默认的编译器和链接器；
2. 用"LDFLAGS=-L <交叉编译器安装路径里的lib目录>"来指定链接时搜索共享库的路径
3. 把“CXXFLAGS= -g -I/usr/local/include”里的路径改成你交叉编译器安装路径里的include目录；
4. 把Makefile里g++用$(LD)代替，"-L /usr/local/lib"用$(LDFLAGS)代替；

另外，注意根据

-lexpat -lpthread

你需要ARM版本的libexpat.so和libpthread.so。 通常它们包含在交叉编译器的安装包里，如果没有的话，你需要自己预先交叉编译好并且安装到交叉编译器的安装路径里。

#CXXFLAGS= -g -I/home/work/toolschain/4.4.3/include

simple_quoter_server: $(simple_quoter_server_objects)
        arm-linux-gcc -L/home/work/toolschain/4.4.3/lib \
        -I/home/work/toolschain/4.4.3/include\
        -o sqs $(simple_quoter_server_objects) \
        -lexpat -lpthread

simple_quoter_client: $(simple_quoter_client_objects)
        arm-linux-gcc -L/home/work/toolschain/4.4.3/lib \
        -I/home/work/toolschain/4.4.3/include\
        -o sqc $(simple_quoter_client_objects) \
        -lexpat -lpthread

我改成这样可以么？

Makefile没深入写过，能不能帮忙改下。

谢谢，问题已经解决了
