c )make error& link problem: i386:x86-64 architecture of input file, incompatible with i386 output
提问by user890040
I have this output with error message when i type "make" in terminal!!
当我在终端中输入“make”时，我有这个带有错误信息的输出！！
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
Is there anyone who can explain why and how to fix it? :(
有没有人可以解释为什么以及如何解决它？:(
I'm attaching makefile just in case
我附上makefile以防万一
# Comment out the targets you don't want.
# Runs all of the tests.

./test1

./test3
./test4

You probably have some old files (at least test1.o) compiled for i386-x64. You can remove these old files and run make again. If you can modify the Makefile try adding a line such as:
您可能有一些为 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，请尝试添加一行，例如：
clean:
rm *.o test1 test2 test3 test4 test5 testFor
Then when you run make cleanit'll remove the old stuff, at which point you can run make again.
然后当你运行make clean它会删除旧的东西，此时你可以再次运行 make 。

I had similar problem. Problem for me was that object files were generated with i386 arichitecture and I was trying to link with x86_64 linker. I deleted object files generated them anew with x86_64 options and tried to linking again. It works now
我有类似的问题。对我来说问题是目标文件是用 i386 架构生成的，我试图用 x86_64 链接器链接。我删除了使用 x86_64 选项重新生成它们的目标文件，并尝试再次链接。它现在有效

If the makefile is generated for the system, you should run ./configure to get new ones, and then recompile.
如果为系统生成了makefile，则应该运行./configure 来获取新的，然后重新编译。
