rules_gtsam

Rules for building GTSAM with bazel. Heavily inspired by rules_pcl.

How to use

In your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_gtsam",
    url = "https://github.com/aharmat/rules_gtsam/archive/main.tar.gz",
    sha256 = "1cf2f543d11c8d4fea77252299fbaf8297f35b454b2b502112be0ab193b39948",
    strip_prefix = "rules_gtsam-main",
)

load("@rules_gtsam//bzl:repositories.bzl", "gtsam_repositories")
gtsam_repositories()

# NOTE: This must be loaded after the call to gtsam_repositories().
load("@rules_gtsam//bzl:init_deps.bzl", "gtsam_init_deps")
gtsam_init_deps()

In your top-level BUILD.bazel file:

load("@rules_gtsam//bzl:gtsam.bzl", "gtsam_config")
load("@rules_gtsam//bzl:gtsam.bzl", "gtsam_dllexport")

gtsam_config()
gtsam_dllexport(library_name="gtsam")
gtsam_dllexport(library_name="gtsam_unstable")

To define a target that depends on GTSAM:

cc_binary(
    name = "example",
    srcs = ["main.cc"],
    deps = ["@gtsam//:gtsam"],
)

cc_binary(
    name = "example2",
    srcs = ["main2.cc"],
    deps = ["@gtsam//:gtsam_unstable"],
)

Current limitations:

• TBB is not supported, so Boost pool is the default allocator
• Metis is not supported, so GTSAM_SUPPORT_NESTED_DISSECTION is False
• GeographicLib is not supported, so anything that depends on it will fail to compile
• Tests are not built
• All files that depend on CppUnitLite are excluded
