Build GOTCHA

This section describes how to build GOTCHA, and what configure time options are available.

There are two build options:

• build GOTCHA with Spack, and

• build GOTCHA with cmake

---

Build GOTCHA with Spack

One may install GOTCHA with Spack. If you already have Spack, make sure you have the latest release. If you use a clone of the Spack develop branch, be sure to pull the latest changes.

Install Spack

$ git clone https://github.com/spack/spack
$ # create a packages.yaml specific to your machine
$ . spack/share/spack/setup-env.sh

Use Spack’s shell support to add Spack to your PATH and enable use of the spack command.

Build and Install GOTCHA

$ spack install gotcha
$ spack load gotcha

If the most recent changes on the development branch (‘dev’) of GOTCHA are desired, then do spack install gotcha@develop.

Attention

The initial install could take a while as Spack will install build dependencies (autoconf, automake, m4, libtool, and pkg-config) as well as any dependencies of dependencies (cmake, perl, etc.) if you don’t already have these dependencies installed through Spack or haven’t told Spack where they are locally installed on your system (i.e., through a custom packages.yaml). Run spack spec -I gotcha before installing to see what Spack is going to do.

Build GOTCHA with CMake

Download the latest GOTCHA release from the Releases page or clone the develop branch (‘develop’) from the GOTCHA repository https://github.com/LLNL/GOTCHA.

cmake . -B build -DCMAKE_INSTALL_PREFIX=<where you want to install GOTCHA>
cmake --build build
cmake --install build
