description	Instructions for building Smith

Compute-node requirement (Codex)

Only run compilation and test commands on a compute node. Determine this by running:

./skills/building/scripts/is_compute_node

If it prints login, do not run ./config-build.py, cmake --build ..., or ctest .... Stop and ask the user to switch to/allocate a compute node, then continue once is_compute_node prints compute.

This repository supports two build workflows:

• Smith-only (default): builds Smith against externally provided TPLs (e.g., via Spack/uberenv + a host-config).
• Co-develop Smith (opt-in): additionally builds the mfem, axom, and tribol git submodules as CMake subdirectories.

Smith-only build (default)

1. Configure (recommended wrapper around CMake):

./config-build.py -bp build -ip install -hc "$(./skills/building/scripts/determine_host_config)" --exportcompilercommands

3. Build and test:

cmake --build build -j
ctest --test-dir build

Co-develop Smith (MFEM + Axom + Tribol)

Use this only when you intend to modify/build Smith against the submodules.

1. Initialize submodules (required):

git submodule update --init --recursive

2. Configure with co-develop enabled:

./config-build.py -bp build-codevelop -ip install-codevelop -hc "$(./skills/building/scripts/determine_host_config)" -DSMITH_ENABLE_CODEVELOP=ON --exportcompilercommands

3. Build and test:

cmake --build build-codevelop -j
ctest --test-dir build-codevelop

Common build options

Common CMake options (and their defaults) live in cmake/SmithBasics.cmake. Pass them at configure time as -D<OPTION>=ON|OFF, for example:

./config-build.py -hc "$(./skills/building/scripts/determine_host_config)" -DENABLE_ASAN=ON

Build types (when requested)

Only set a build type when the user explicitly asks for one. Use config-build.py's -bt option, which takes a CMake build type (e.g., Debug, Release, RelWithDebInfo, MinSizeRel):

./config-build.py -bp build -ip install -hc "$(./skills/building/scripts/determine_host_config)" -bt <CMAKE_BUILD_TYPE> --exportcompilercommands

AddressSanitizer (ENABLE_ASAN)

AddressSanitizer is available via the ENABLE_ASAN CMake option (default: OFF). It is supported with GCC or Clang. This should also build in with the CMake build type Debug by default.

./config-build.py -hc "$(./skills/building/scripts/determine_host_config)" -bt Debug -DENABLE_ASAN=ON

Host-config selection (-hc)

If the user does not specify a host-config file, determine the best match by running:

./skills/building/scripts/determine_host_config

Use its output as the -hc argument (as shown in the examples above). If the user explicitly provides a host-config file/path, use that instead.
