Recipe for target 'wp77' failed - Error 1

#1

Hi All,

New to MangOH, just got a board recently and working through installing Legato environment and the basic tutorials now.

I have installed the WP7702 CF3 module, working through the instructions on

and

The device itself is pinagable.

I downloaded and installed legato-18.01.0-R8-WP77-linux-64bit.zip.

Running through the examples, I am encountering problems with building the HelloWorld example program.

I navigate to the HelloWorld folder using CLI and type

$make wp77

And I get a whole lot of messages. The following is the output after the above CLI command:

Makefile:7: recipe for target ‘wp77’ failed
make: *** [wp77] Error 1

I have looked through forums and found similar looking errors, however I can’t progress from here based on the info that I have found.
Is there something really obvious going on here? Assistance would be greatly appreciated.

Cheers,
Aleo

Hi Aleo, it happened twice to to me on a MangOH Red as well. The first time went away after reinstalling but I didn’t know exactly why. After checking the number of files in the legato framework directory and making sure that my new installation had all the scripts of the original one I could move on and make for all modems.

To find the number of files in both directories I used:

find legato_framework -type f | wc -l 

Hope it helps for you as well.
Marc
