godep and dependency management

Mindfly uses godep to manage dependencies. It is not strictly required for building Mindfly but it is required when managing dependencies under the Godeps/ tree, and is required by a number of the build and test scripts. Please make sure that godep is installed and in your $PATH.

Installing godep

There are many ways to build and host go binaries. Here is an easy way to get utilities like godep installed:

Create a new GOPATH for your tools and install godep:

export GOPATH=$HOME/go-tools
mkdir -p $GOPATH
go get github.com/tools/godep

Add $GOPATH/bin to your path. Typically you'd add this to your ~/.profile:

export GOPATH=$HOME/go-tools
export PATH=$PATH:$GOPATH/bin

Using godep

Here's a quick walkthrough of one way to use godeps to add or update a Mindfly dependency into Godeps/_workspace. For more details, please see the instructions in godep's documentation.

cd $GOPATH/src/github.com/cheyang/numa-utils
git pull https://github.com/cheyang/numa-utils.git
godep restore -v
# To add a new dependency, do:
go get path/to/dependency
godep save ./...

Build

cd $GOPATH/src/github.com/cheyang/numa-utils
make

Make sure `libnuma.so.1` is in you LD_LIBRARY_PATH or default lib path like `/usr/lib`

you can download ftp://oss.sgi.com/www/projects/libnuma/download/numactl-2.0.11.tar.gz
