[dmn-star]

I have always turned off the three below, maybe it's an option for you too.

boost:without_locale = True
boost:without_log = True
boost:without_stacktrace = True

[granger35]

Thank you @dmn-star ,

You are right, without_locale and without_log turned to True do the job, but i need the boost logs (and logs are required if without_local is set to True).
I have to set i18n_backend_iconv to libiconv for now, default libc does not work.

[SSE4]

checking the config.log I see the error:

  6 Undefined symbols for architecture arm64:
  7   "_iconv_open", referenced from:
  8       _main in has_iconv_libc_obj.o
  9 ld: symbol(s) not found for architecture arm64

perhaps, android's libc (bionic) doesn't provide iconv interface? let's check, and if so, for Android we should use libiconv as a default backend (instead of libc iconv).

[SSE4]

found answer: android/ndk#702
TLDR: iconv is provided by bionic since API level 28
for lower API levels we should default to i18n_backend_iconv = "libiconv"
I'll prepare the fix

[granger35]

Thank you for pointing out the problem and fixing it.
