c )make error& link problem: i386:x86-64 architecture of input file, incompatible with i386 output
Solution 1
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:
clean:
rm *.o test1 test2 test3 test4 test5 testFor
Then when you run make clean
it'll remove the old stuff, at which point you can run make again.
Solution 2
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
Solution 3
If the makefile is generated for the system, you should run ./configure to get new ones, and then recompile.

I have this output with error message when i type "make" in terminal!!
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? :(
I'm attaching makefile just in case

user786653 almost 13 yearsPaste the Makefile. But the problem, as it is telling you, is that some of the files have been compiled (implicitly or explicitly with
-m64
) while the link target (and possibly other object files) are handled with-m32
. -
user786653 almost 13 yearsThe Makefile looks fine (except you should really use the
-pthread
switch on everyfile). Perhaps you've moved the project from another machine, have you tried removing the object files and recompiling? -
user890040 almost 13 yearsHm.. no.. I actually tried this at uni and worked fine(actually Makefile is given by the lecturer haha).. hmm how to you remove the object files?

Havelock almost 12 years+1 I just had the same problem and Google brought me here. After running
make clean
it worked :)
