cannot compile obj/content/browser/content.time_zone_monitor.o because of a undefined reference.

[Mark Enriquez]

I have tried to compile chromium source from commondatastorage.googleapis.com/chromium-browser-official, version 44.0.2403.4, but cannot get pass this  error:

../../content/browser/time_zone_monitor.cc: In member function ‘void content::TimeZoneMonitor::NotifyRenderers()’:
../../content/browser/time_zone_monitor.cc:30:29: error: ‘detectHostTimeZone’ is not a member of ‘icu_52::TimeZone’
   icu::TimeZone* new_zone = icu::TimeZone::detectHostTimeZone();
                             ^
ninja: build stopped: subcommand failed.

I'm using the system (ubuntu 15.04) libraries and headers and tried using either libicu 55 or libicu 52 from source and package, '-Duse_system_icu=1'  in running  build/gyp_chromium and  build/linux/unbundle/replace_gyp_files.py. I also tried  

build/linux/unbundle/remove_bundled_libraries.py 'base/third_party/icu' --do-remove

Changing detectHostTimeZone to createDefault  let me build the target but a part of the comment in the timezone.h seem to show that something may not go right in the future. That part is in Bold.

    /**
     * Creates an instance of TimeZone detected from the current host
     * system configuration. Note that ICU4C does not change the default
     * time zone unless TimeZone::adoptDefault(TimeZone*) or
     * TimeZone::setDefault(const TimeZone&) is explicitly called by a
     * user. This method does not update the current ICU's default,
     * and may return a different TimeZone from the one returned by
     * TimeZone::createDefault().
     *
     * @return  A new instance of TimeZone detected from the current host system
     *          configuration.
     * @draft ICU 55
     */
    static TimeZone* U_EXPORT2 detectHostTimeZone();

Could anyone help me on this?

Which target have you tried to build? Shared or static build? What are your settings?

I've tried to building it in 64-bit, shared build. I used mostly the libraries provided by the distribution (ubuntu 15.04) aside from libvpx and icu. In running build/gyp_chromium  I passed these  arguments :

Try not setting any gyp defines and see if that works first.

The build takes a very long time on this machine but it seems it will build successfully as the obj/content/browser/content.time_zone_monitor.o will not be compiled.

ninja -C out/Release  obj/content/browser/content.time_zone_monitor.o  
ninja: Entering directory `out/Release'
ninja: error: unknown target 'obj/content/browser/content.time_zone_monitor.o'

[Nico Weber]

Then I suppose the gyp define combination you're using isn't supported.
