<Openfree`> anyone has expience build chromium on gentoo-arm, I'm using OMAP4 pandaboard
<Openfree`> while using chromium-14.0.803.0, first encounter unrecognize neon instruction problem, because I'm using -mfp=vfpv3-d16
<Openfree`> then I swith to -mfpu=neon, then have problem with -DUSE_EABI_HARDFLOAT, because of enable -mfloat-abi=hard
<Openfree`> I'm trying to add this, not sure it will work, http://paste.pocoo.org/show/432028/
<Openfree`> oops, better file a bug report
<Openfree`> also have problem with firefox :-(

[Comment 2 Yixun Lan 2011-07-07 10:08:23 UTC]

I've try to add this, but with no luck,
expect result should see  -DUSE_EABI_HARDFLOAT when come to build v8
but I look at log, haven't seen yet

Created attachment 279313 [details]
full build log of chromium

decompressed log takes 4.8MB, so I compress it

[Comment 4 Yixun Lan 2011-07-07 13:55:22 UTC]

Created attachment 279329 [details]
this patch enable eabi_hardfloat

after apply this patch, you can see compile v8 will enable '-DCAN_USE_VFP_INSTRUCTIONS' '-DUSE_EABI_HARDFLOAT=1'

[Comment 5 Yixun Lan 2011-07-07 22:04:12 UTC]

that patch works, now I compile successfully.

[Comment 6 Yixun Lan 2011-07-07 22:05:01 UTC]

also should remove line "doins out/Release/libppGoogleNaClPluginChrome.so || die"
there is no this file after compiling

[Comment 7 Paweł Hajdan, Jr. (RETIRED) 2011-07-17 04:33:27 UTC]

Sorry, I think that ebuild isn't even keyworded ~arm, and I think hardfload is not (yet) supported by upstream.
