Hi everyone
When I run:
tools/dev/gm.py x64.release
Everything works fine but no libv8_monolith.a is created.
So, I changed gm.py and add "v8_monolithic = true
v8_use_external_startup_data = false" and run again.
RELEASE_ARGS_TEMPLATE = f"""\
is_component_build = false
is_debug = false
%s{BUILD_DISTRIBUTION_LINE}
v8_enable_backtrace = true
v8_enable_disassembler = true
v8_enable_object_print = true
v8_enable_verify_heap = true
dcheck_always_on = false
v8_monolithic = true
v8_use_external_startup_data = false
"""
and then run:
autoninja -C out/x64.release
finally I have libv8_monolith.a
BUT....
if I run this command to make the configuration:
tools/dev/v8gen.py x64.release.sample
and then:
autoninja -C out.gn/x64.release.sample/ v8_monolith
the result is this error (basically std::bit_cast not found):
offline mode
