[[: not found about nano_build_opencv HOT 4 CLOSED

@Hongbo-Miao

Thank you for reporting the issue. I can't replicate.

• What version of bash are you running (bash --version)?
• What version of the script are you running (it should have #!/usr/bin/env bash at the top of the file)?

1. I am using the macOS to ssh into Jetson Nano to run the script.

   This is what returned after running

   bash --version
   

   on my macOS.

   GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin18)
   Copyright (C) 2007 Free Software Foundation, Inc.

2. I downloaded and ran this script two days ago, it has #!/usr/bin/env bash on the top of the file.

Sorry for not specifying. I meant the version of bash on the Nano, not your host.

The version of bash reported by my nano is:

GNU bash, version 4.4.20(1)-release (aarch64-unknown-linux-gnu)

When you ssh into the Nano run the build script, are you running it directly like ./build_opencv.sh or are you doing sh build_opencv.sh? If it's the latter, that could explain the error. The latter would use the bourne shell (/bin/sh) or a clone, rather than bash, and some syntax is slightly different. The script won't work if launched with /bin/sh.

Oh, I think you are right, I remembered I was using sh build_opencv.sh. Thanks for explanation!
