• Quickstart: Record traces on Linux
• Cross-compiling for Linux ARM/64

方法1

直接在arm64機器或者容器里編譯。

git clone https://android.googlesource.com/platform/external/perfetto/ && cd perfetto
tools/install-build-deps
tools/gn gen --args='is_debug=true is_clang=false' out/linux
tools/ninja -C out/linux tracebox traced traced_probes perfetto

方法2

交叉編譯。

• 配置

git clone https://android.googlesource.com/platform/external/perfetto/ && cd perfetto
tools/install-build-deps --linux-arm
tools/gn gen --args='is_debug=true is_clang=false target_cpu="arm64" target_os="linux" target_triplet="aarch64-none-li
nux-gnu"' out/linux_arm64

配置完畢，在out/linux_arm64/args.gn中可以查看配置結果：

$ cat out/linux_arm64/args.gn
is_debug = true
is_clang = false
target_cpu = "arm64"
target_os = "linux"
target_triplet = "aarch64-none-linux-gnu"

在out/linux_arm64/toolchain.ninja中：

$ cat out/linux_arm64/toolchain.ninja  | head -n 10
rule solink
  command =  aarch64-none-linux-gnu-g++ -fuse-ld=gold -shared ${ldflags}   @${root_out_dir}/${target_output_name}${output_extension}.rsp ${solibs} ${libs} -Wl,-soname,${target_output_name}${output_extension} -o ${root_out_dir}/${target_output_name}${output_extension} && aarch64-none-linux-gnu-strip -o ${root_out_dir}/stripped/${target_output_name}${output_extension} ${root_out_dir}/${target_output_name}${output_extension}
...
