c)出错和链接问题:i386:x86-64输入文件架构,与i386输出不兼容

Question

当我在终端输入"make"时,我输出错误信息!!

gcc test1.o dispatchQueue.o -o test1 -pthread
/usr/bin/ld: i386:x86-64 architecture of input file `test1.o' is incompatible with i386     output
/usr/bin/ld: final link failed: Invalid operation
collect2: ld returned 1 exit status
make: *** [test1] Error 1

有没有人可以解释为什么以及如何解决它？:(

我附加makefile以防万一

# Comment out the targets you don't want.

# Runs all of the tests.
all: test1 test2 test3 test4 test5 testFor
    ./test1
    ./test2
    ./test3
    ./test4
    ./test5
    ./testFor

test1: test1.o dispatchQueue.o
    gcc test1.o dispatchQueue.o -o test1 -pthread

test1.o: test1.c
    gcc -c test1.c

test2: test2.o dispatchQueue.o
    gcc test2.o dispatchQueue.o -o test2 -pthread

test2.o: test2.c
    gcc -c test2.c

test3: test3.o dispatchQueue.o
    gcc test3.o dispatchQueue.o -o test3 -pthread

test3.o: test3.c
    gcc -c test3.c

test4: test4.o dispatchQueue.o
    gcc test4.o dispatchQueue.o -o test4 -pthread

test4.o: test4.c
    gcc -c test4.c

test5: test5.o dispatchQueue.o
    gcc test5.o dispatchQueue.o -o test5 -pthread

test5.o: test5.c
    gcc -c test5.c

testFor: testFor.o dispatchQueue.o
    gcc testFor.o dispatchQueue.o -o testFor -pthread

testFor.o: testFor.c
    gcc -c testFor.c

dispatchQueue.o: dispatchQueue.c dispatchQueue.h
    gcc -c dispatchQueue.c

你可能有一些为i386-x64编译的旧文件(至少是test1.o).您可以删除这些旧文件并再次运行make.如果您可以修改Makefile,请尝试添加以下行:

clean:
    rm *.o test1 test2 test3 test4 test5 testFor

然后当你运行make clean它时,将删除旧的东西,此时你可以再次运行make.
