Identify modules ready to be converted to Soong
The output will be in the `m dist` results as soong_to_convert.txt, or
can be built using:
$ m $OUT/soong_to_convert.txt
The output is a list of modules that are probably ready to convert to
Soong:
# Blocked on Module (potential problems)
283 libEGL (srcs_dotarm)
246 libicuuc (dotdot_incs dotdot_srcs)
221 libspeexresampler
215 libcamera_metadata
...
0 zram-perf (dotdot_incs)
The number at the beginning of the line shows how many native modules
depend on that module.
All of their dependencies have been satisfied, and any potential
problems that Make can detect are listed in parenthesis after the
module:
dotdot_srcs: LOCAL_SRC_FILES contains paths outside $(LOCAL_PATH)
dotdot_incs: LOCAL_C_INCLUDES contains paths include '..'
srcs_dotarm: LOCAL_SRC_FILES contains source files like <...>.c.arm
aidl: LOCAL_SRC_FILES contains .aidl sources
dbus: LOCAL_SRC_FILES contains .dbus-xml sources
objc: LOCAL_SRC_FILES contains Objective-C sources
proto: LOCAL_SRC_FILES contains .proto sources
rs: LOCAL_SRC_FILES contains renderscript sources
vts: LOCAL_SRC_FILES contains .vts sources
Not all problems can be discovered, but this is a starting point.
