Building embeddable version of V8 as static library with minimal binary size

[Yukkuri Shiteimasu]

Hi, I am trying to incorporate ES6 JavaScript engine into my small single-binary GUI application for scripting purposes and have chosen V8 as such implementation, but having hard time building minimal static library.

My flags I used in hope of creating small binary are:

--->3---

is_debug = false

target_cpu = "x64"

is_component_build = false

strip_debug_info = true

symbol_level = 0

v8_static_library = true

v8_enable_i18n_support = false

v8_use_snapshot = false

v8_enable_disassembler = false

v8_enable_gdbjit = false

v8_enable_handle_zapping = false

v8_no_inline = true

v8_monolithic = true

v8_experimental_extra_library_files = []

v8_extra_library_files = []

v8_enable_concurrent_marking = true

v8_enable_embedded_builtins = false

is_desktop_linux = false

icu_use_data_file = false

enable_iterator_debugging = false

enable_precompiled_headers = false

clang_use_chrome_plugins = false

asan_globals = false

libcpp_is_static = true

use_aura = false

use_dbus = false

use_gio = false

use_glib = false

use_icf = false

use_udev = false

--->3---

Also tried adding -Os to CFLAGS.

But resulting out.gn/x64.release/obj/libv8_base.a is about 25Mb in size even after the stripping, which is hardly can be embedded into small application (being ~25 times the application size itself).

As I read earlier in this group, some had achieved results of about ~2.5Mb[1], which is almost acceptable for my purposes, and so I wonder, what could I tune (drop, disable, exclude or otherwise, while maintaining core ES6 functionality) in order to get small static binary?

Did you ever figure this out?

Hi,

Able to get reduced size of v8 libs for this?. We are seeing v8_base.a size is coming around 8 MB. Please let me know, if you got any changes/config to be made to reduce size.

Thanks.

needs to minimize static library size too, any guidelines?
