The script ./build will help with building and installing Maude. Run ./build help for instructions on how to use.

• GNU gcc
• GNU bison
• GNU flex

It is recommended that you use the latest versions of bison and flex since Maude is known to tickle bugs in certain older versions. You should use gcc 3.1 or later as there are code generation issues with the 3.0.* series. Maude requires the following packages:

On Ubuntu, you can run:

sudo apt install gcc bison flex

Additionally, you'll need:

• GNU gmp
• GNU libsigsegv
• Tecla
• BuDDY

On Ubuntu, you can run:

sudo apt install libgmp-dev libsigsegv-dev libtecla-dev libbdd-dev

• CVC4
• Yices2
• GNU gperf (for Yices2)

NOTE: There is not an Ubuntu package for Yices2 yet.

On Ubuntu, you can run:

sudo apt install cvc4 gperf

First build the dependencies:

./build deps

Then build Maude (with or without an SMT solver):

./build maude           # No SMT Solver
./build maude-cvc4      # CVC4 SMT Solver
./build maude-yices2    # Yices2 SMT Solver

Merging into master will only occur when the following have been done:

1. The feature branch is rebased on master.
2. All tests in the repository pass.
3. Code review has approved the changes.

Each feature/topic branch should use the following naming prefix scheme. If your branch falls into two categories, pick the earlier one in this list.

• build/FEATURE-NAME: Branches which modify/update the build system.
• core/FEATURE-NAME: Any branch that touches code in src/ (modifying Core Maude).
• tools/FEATURE-NAME: Branches which work in the contrib/tools directory.
• systems/FEATURE-NAME: Branches which add systems to the contrib/systems directory.
• doc/FEATURE-NAME: Branches which work on repository documentation.

The actual merge into master will be performed using the merge-pr script in contrib/scripts.

./contrib/scripts/merge-pr BRANCH 'PULL-REQUEST-NAME'
git push upstream master

with:

• BRANCH as the branch to be merged.
• PULL-REQUEST-NAME as the GitHub pull-request name.

This creates an empty merge commit which marks the feature addition/bug-fix. It's assumed that the remote you're pushing to is named upstream.
