Cobalt 24 LTS - crashpad_handler build issue

[ramasr...@gmail.com]

Hi ,

The 24.10.lts build is failing for crashpad_handler , loader_app is OK.

ninja: error: unknown target 'crashpad_handler'

What can be wrong ?

Thanks,

sri

Hi Sri,

Starting in 24 LTS crashpad handler must be built in a different way. Please see the instructions at https://github.com/youtube/cobalt/blob/main/starboard/doc/evergreen/cobalt_evergreen_overview.md#building-cobalt-evergreen-components.

To summarize, you'll need to define a new "native_target" toolchain in the port, and the ninja build target should now be `native_target/crashpad_handler`.

Thanks,

Holden

Thanks you Holden. Somehow the build worked for the previous RC releases of cobalt 24 , by commenting out  crashpad "native_target" dependencies .

Added native target support to toolchain/BUILD.gn ,  This is causing Boring SSL native build failure..

that error is fixed by setting "asm_target_arch" . 

  toolchain_args = {
    current_os = "linux"
    asm_target_arch = "arm"
    is_starboard = false
    is_native_target_build = true
    if(_refsw_arch == "aarch64-linux") {
      current_cpu = "arm64"
    } else if(_refsw_arch == "arm-linux") {
      current_cpu = "arm"
    }
    is_clang = false
  }

But still crahpad_handler error is seen

______

ninja -C out/bt_arm_gold loader_app crashpad_handler
ninja: Entering directory `out/bt-arms_gold'

ninja: error: unknown target 'crashpad_handler'

Thanks,

Sorry , forgot to set  native_target/crashpad_handler . It is fixed now. 

It seems setting native_target requires its own set of parameters . Many other build errors are seen . somehow it is looking for clang++ ,  even with is_clang is set to false.

I am not clear the need of native_target to start with. loader_app, crashpad handler both need to run on the target anyway. And BUILD.gn of crashpad decides not to depend on starboard.

Thanks,

Hi Holden,

downloading newer version of clang fixed some errors. . Crash pad build is failing because of many unresolved symbols from boring ssl.  It seems more changes are required for crashpad native target build.  can a platform not use native target build like is the case with cobalt 23 ?

Thanks,

Sri

It is fixed. Have to check if it runs OK.

Thanks,
