[features]
# by default, building libelf is disabled.  It must be explicitly enabled
default = []

# if this feature is enabled, then the build.rs will try to build the libelf binaries.
# if the build fails, this crate's build will still succeed
#
# The success or failure of the build will be communicated via a variable in cargo,
# which dependent crates can resolve with DEP_LIBELF_SYS_SUCCEEDED
enabled = ["libz-sys", "libc"]

# If this feature is enabled, it implies `enabled`, and also will cause the build to fail if
# libelf cannot be built
