Go compile failed without any warning or error

Getting Help

I encountered an issue while compiling syzkaller (a customized version of syzkaller, based on syzkaller commit a371c43c33b6f901421f93b655442363c072d251,Compiling on this commit was successful).
When using make fuzzer, I received a message saying

build constraints exclude all Go files in xxx

here is the full output

make: *** [Makefile:158: fuzzer] Error 1

Since my environment is amd64 and Linux, I thought this would be normal; however, the compilation failed.

I tried to use -x and -v to display the compilation logs, but -v did not produce any output, and the file /tmp/go-xxxxx generated by -x was empty.

I would like to know why the compilation fails, as it does not display any errors or warnings. Is there any way to make Go show this information?

  • While uncommon, the compiler might have encountered errors it didn’t report clearly. Try running go build instead. go build can sometimes provide more verbose output compared to go compile.
