Note that options for hidl-gen expected to be invoked by the build system are marked with 'internal' in the help menu.
hidl-gen -h hidl-gen -o output -L c++-impl -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
Some defaults for package roots are also provided
hidl-gen -o output -L c++-impl android.hardware.nfc@1.0 hidl-gen -o output -L vts android.hardware.nfc@1.0 hidl-gen -L hash android.hardware.nfc@1.0
Example command for vendor project
hidl-gen -L c++-impl -r vendor.foo:vendor/foo/interfaces vendor.foo.nfc@1.0
See update-makefiles-helper.sh and update-all-google-makefiles.sh for examples of how to generate HIDL makefiles (using the -Landroidbp option).
This is a helper tool to convert C headers to valid .hal files.
m c2hal && c2hal -h
