udev linker errors

[manik sheeri]

Hi

I am trying to build chromium with my custom toolchain. The Chromium version I am using is 37.0.2062.120

My build configuration is :

myconf="

-Dwerror= 

-Duse_openssl=1

 -Duse_system_ffmpeg=0

 -Dbuild_ffmpegsumo=1

 -Dproprietary_codecs=1 

-Dremove_webcore_debug_symbols=1

 -Dlogging_like_official_build=1 

-Ddisable_sse2=1

 -Denable_google_now=0

 -Denable_plugin_installation=0 

-Duse_gnome_keyring=0 

-Ddisable_nacl=1

 -Ddisable_pnacl=1

 -Duse_gconf=0

 -Duse_gio=0

 -Denable_hangout_services_extension=0 

-Denable_wifi_bootstrapping=0

 -Duse_pulseaudio=0 

-Duse_system_libexif=0

 -Duse_kerberos=0"

The configuration command I used is :

./build/gyp_chromium build/all.gyp --depth . $myconf

Build command:

../ninja-1.5.1/ninja -C out/Release chrome

Build environment Variables:

export LDFLAGS="-Wl,--rpath-link,/usr/custom-toolchain/lib \

-Wl,--dynamic-linker,/usr/custom-toolchain/lib/ld-linux.so.2"

export PKG_CONFIG_PATH="/usr/custom-toolchain}/lib/pkgconfig"

The compilation succeeds but I have got linker errors for 'udev' library.

Questions :

Chromium is built as a static executable. Right ?

Does that mean, it is looking for static 'libudev' library ?

I can see using pkg-config that libudev is installed.

I explicitly added the following 'ldflags' tag for the 'udev' target in system.gyp :

{

      'target_name': 'udev',

      'type': 'none',

      'conditions': [

        # libudev is not available on *BSD

        ['_toolset=="target" and os_bsd!=1', {

          'direct_dependent_settings': {

            'cflags': [

              '<!@(<(pkg-config) --cflags libudev)'

            ],

   'ldflags': [

              '<!@(<(pkg-config) --libs-only-L --libs-only-other libudev)',

            ],

          },

          'link_settings': {

            'ldflags': [

              '<!@(<(pkg-config) --libs-only-L --libs-only-other libudev)',

            ],

            'libraries': [

              '<!@(<(pkg-config) --libs-only-l libudev)',

            ],

          },

        }],

      ],

    },

But this change doesn't help.

any idea what could be causing such issue ?

Thanks.

[Lei Zhang]

So what is the "pkg-config --libs-only-L --libs-only-other libudev"
and "pkg-config --libs-only-l libudev" output with your custom
toolchain?

I'm assuming use_udev is set to 1 in your gyp config? You listed a
whole bunch of build options, but left out the one that's actually
relevant.

Also, there's no need to list all the errors without the failing
command that's being executed. You basically just enumerated all the
places where we use udev.

pkg-config --libs-only-L --libs-only-other libudev 

-L/usr/custom-toolchain/lib

pkg-config --libs-only-l libudev 

-ludev

Looking into the common.gypi file for the 'udev'

 # libudev usage.  This currently only affects the content layer.

        ['OS=="linux" and embedded==0', {

          'use_udev%': 1,

        }, {

          'use_udev%': 0,

        }],

I think 'udev' is set to 1 because I have not set embedded=1.

Also, looking into the .ninja file for content_browser, I can see the '-DUSE_UDEV' in defines

I actually did not intend to write the whole error list, but don't know why I pasted all of it :)

May be I am too bored right now. ha ha. Nevermind, it's fun playing around with chromium so far.

Thanks.

[Lei Zhang]

Do you have /usr/custom-toolchain/lib/libudev.so? If it's a symlink,
make sure it's pointed to the right libudev.so.{0,1}.

[manik sheeri]

ls -al /usr/custom-toolchain/lib/libudev.so shows that

/usr/custom-toolchain/lib/libudev.so -> libudev.so.0.4.0

[Lei Zhang]

libudev.so.0.4.0 looks old. Does it have all the symbols that the
linker is looking for?

You can try manually running the final link command, but add
-Wl,--verbose to the end. Assuming you are using gold, it will show
you debug messages like:

/path/to/ld.gold: Attempt to open
/usr/lib/gcc/x86_64-linux-gnu/4.8/libglib-2.0.so failed
/path/to/ld.gold: Attempt to open
/usr/lib/gcc/x86_64-linux-gnu/4.8/libglib-2.0.a failed
/path/to/ld.gold: Attempt to open
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libglib-2.0.so
succeeded

Look for libudev and see what the linker is (not) finding.

[manik sheeri]

I checked for the undefined symbols using 

nm --demangle /usr/custom-toolchain/lib/libudev.so | grep -i <symbol name>

The symbols are present in the library.

What is 'gold' ?

My linker command(at the link stage of the build) as per the ninja build system was:

ninja: Entering directory `out/Release'

[1/1] LINK chrome

(The whole command is very long, but this should give the idea)

[Lei Zhang]

Gold is shiny, and also the name of a linker. You may be using GNU ld,
which also accepts --verbose. In either case, manually run the very
long command with -Wl,--verbose and you'll gain more visibility into
what the linker is doing and why it can't find libudev.

[manik sheeri]

"all that glitters is not gold"  :)

Anyways, I was able to find and fix the problem.

The "libudev.h" header file in my custom toolchain path didn't have ' extern "C" {} for when cplusplus is defined'.

Thanks for the help.

I was successfully able to compile and link the chrome for the above mentioned configuration.

However, inside out/Release directory when I execute the "./chrome" command it gives me the following error

[13110:13110:1021/231934:FATAL:browser_main_loop.cc(158)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.

Aborted

Any idea what this is about?

[Lei Zhang]

Read the link and find out.

That, or just do:

out/Release/chrome --no-sandbox

;)

Gold is a linker developed mostly by Ian Lance Taylor at Google. It was released with speed in mind.

You can learn more about it at http://research.google.com/pubs/pub34417.html and http://en.wikipedia.org/wiki/Gold_(linker)

[manik sheeri]

Thank you. I was able to resolve the problem.

[manik sheeri]

With the same configuration of build as mentioned above, I am able to run the chrome with a sandbox too.

I have enabled plugin installation and therefore I was able to install flash support for chromium.

However, when I try to watch videos on YouTube, I can not play them. I get the black screen with the error.

I am wondering may be it is because I have disabled 'pulse-audio' support for the browser. Right ?

[Lei Zhang]

I think you should start a new thread at this point.

[manik sheeri]

okay.
