Hi,expert

I have a problem in uprobe.

my systemtap version is  (version 3.2/0.168, commit release-3.1-7-ged948abe57a1
+ changes)

my android kernel version is 3.18.24

I use the follow command to build the systemtap module for arm64-android.

sudo systemtap-ubuntu/bin/stap -g -vvvvvvvvvvvvvvv -a arm64 -B    
CROSS_COMPILE=/usr/bin/aarch64-linux-gnu- -r
~/work/project/platform/out/target/product/{product}/obj/KERNEL_OBJ/  -m
myprocess.ko msyprocess_call.stp.back

the context of msyprocess_call.stp.back show below

probe process("*").function("*") {
print_usyms(ubacktrace())
}

and the build is failed,and show the below log

derive-probes process("*").function("*")
semantic error: resolution failed in DWARF builder
   thrown from: elaborate.cxx:1092
semantic error: while resolving probe point: identifier 'process' at

        source: probe process("*").function("*") {
                      ^
