There is no --debug mode for cargo resulting in the following build
failure in ripgrep since its conversion to cargo infrastructure in
commit 342fd3e735:
error: Found argument '--debug' which wasn't expected, or isn't valid in this context

# Cargo package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of package
|
|
# .mk files for Cargo packages. It should be used for all packages that use
|
|
# Cargo as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this Cargo infrastructure requires the .mk file
|
|
# to only specify metadata information about the package: name, version,
|
|
# download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different steps
|
|
# are doing, if needed. For example, if <PKG>_BUILD_CMDS is already defined,
|
|
# it is used as the list of commands to perform to build the package,
|
|
# instead of the default Cargo behaviour. The package can also define some
|
|
# post operation hooks.
|
|
