This is not a question but smth which google hopefully can find.
lib.export_library cc param was renamed to compile_cmd (at least for Relay)
# before:
lib.export_library(path_lib, cc="arm-linux-gnueabihf-g++")
# now:
lib.export_library(path_lib, compile_cmd="arm-linux-gnueabihf-g++")
@weberlo What is the recommended way to create build function for ARMv7 devices now?
before PR-3227 I just did
build_func = cc.cross_compiler(cc="arm-linux-gnueabihf-g++")
But cc.cross_compiler API was changed - string cc was replaced with function compile_func
I ended up with the following code where I create my own function arm_gnueabihf_create_shared just to override default compile_cmd from g++ to arm-linux-gnueabihf-g++
It works but it is not that simple. Do you have better way to get build_func which uses arm-linux-gnueabihf-g++ internally?
from tvm.contrib import cc
def arm_gnueabihf_create_shared(output,
objects,
options=None,
compile_cmd="arm-linux-gnueabihf-g++"):
cc.create_shared(output, objects, options, compile_cmd)
arm_gnueabihf_create_shared.output_format = "so"
