It appears:

Can you help me ?

First check that your binaries (grin-miner) is in the directory you are expecting.
When compiling from source the binaries are created in the ~/grin-miner/target/debug directory.

Linux handles the searchpath a little strange.
If you type “echo $PATH” you get all the paths that are searched for with your command.
Your local position “./” is not included within your $PATH variable.
You need to include your current position when executing your command, ./grin-miner

There is a .profile file that should exist in your /home/username directory if you’re on linux or Users/username directory if you’re on mac.

In your terminal enter these commands

  • cd
  • nano .profile

Copy and paste the following lines at the end of your now open .profile file

  • export PATH="$HOME/grin-miner/target/debug:$PATH"
  • export PATH="$HOME/grin/target/release:$PATH"

Now save an exit your edited .profile with:

  • Ctrl and x keys to exit
  • y to save
  • enter to confirm

Finally, update your path with this command

  • source ~/.profile

Now try grin-miner and see if it runs.

I do. But the problem has not been solved.
I use cloud.google VM Ubuntu 16.04.
When I run :

"cd
git clone https://github.com/mimblewimble/grin-miner.git
cd grin-miner
git submodule update --init
cargo build "

It appear:

" = note: /usr/bin/ld: cannot find -lOpenCL
/usr/bin/ld: cannot find -lOpenCL
collect2: error: ld returned 1 exit status

error: aborting due to previous error

error: Could not compile ocl_cuckatoo. "

I don’t know where the problem is.

Info from grin-miner instructions…

Building the OpenCL plugins

OpenCL plugins are not enabled by default. Run install_ocl_plugins.sh script to build and install them.

./install_ocl_plugins.sh

You must install OpenCL libraries for your operating system before. If you just need to compile them (for development or testing purposes) build grin-miner the following way:

cargo build --features opencl

I solved the installation problem.
On cloud.google VM Ubuntu ,you should First switch to ROOT(Input command: sudo -i ).
Then installation Grin v0.5 Step by Step.

But there is another problem.
When I run grin-miner it cannot connect.
Grin miner version 0.5.0 appears:
“Connection status: can’t establish server connection to 127.0.0.1:13416. Will retry every 5 seconds
Mining status: waiting for server "
My Grin version 0.5.0 is connected. It appears:
" Current status: running”
"connected peers: 27 "
What should I do ?
