I am using the Android NDK to build a project. This morning the output of ndk-build started displaying tons of output as if I had set a flag somewhere to debug the make process. Below is part of the log, showing where this output starts. The lines I want to get rid of begin with a plus '+' in column 1. 

make[1]: Entering directory `/Users/bgm/svn1.8-workspaces/cur-trunk/repo/trunk/coverage/android/Buckets/jni'

... hundreds of lines like the above that start with '+'

Are you running ndk-build manually in a terminal, or invoked from somewhere?

It seems like something has executed set -x in a parent process to the ndk-build command. To reverse it, run set +x in the same terminal.

  • I'm invoking ndk-build from a Makefile: Here is what I tried based on your suggestion (I added the 'set +x;' That did not solve the problem: (cd jni; set +x; $(NDK_ROOT)/ndk-build) – Sam Mar 04 '15 at 22:44
  • When I run "ndk-build" directly from a terminal command line I also get that extra logging. I tried "set +x" before running ndk-build. That did not fix the problem. – Sam Mar 04 '15 at 23:03
  • "set -x" was the problem. Just before the logging output showed up, I'd modified some components of the build, including taking a new release of a library that included a required build script. The vendor had been debugging that script and put a "set -x" in it. – Sam Mar 05 '15 at 17:43
