Compile your own version

It is possible to follow the steps used to build the current version on Archer2. These steps are codified at the Archer2 github repository and include a number of dependencies to be built in the correct order:

$ git clone
$ cd pe-scripts
$ git checkout cse-develop
$ ./sh/tpsl/ --prefix=/path/to/install/location
$ ./sh/tpsl/ --prefix=/path/to/install/location
$ ./sh/tpsl/ --prefix=/path/to/install/location
$ ./sh/tpsl/ --prefix=/path/to/install/location
$ ./sh/tpsl/ --prefix=/path/to/install/location
$ ./sh/tpsl/ --prefix=/path/to/install/location
$ ./sh/ --prefix=/path/to/install/location
The --prefix option indicating the install directory should be the same in all cases. See the Archer2 github repository for further details (and options).
