965870 - jemalloc.o:jemalloc.c:function malloc_rtree_new: error: undefined reference to 'ffs'

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Nick Alexander :nalexander [he/him]]

I am unable to build Fennec with NDK toolchain r8e and r9 on Mac OS X.  I will try r8c shortly.

I see some old concern about ffs being available on Android (http://cphacker0901.wordpress.com/1900/09/25/build-alsa-with-androids-tool-chain/).

glandium: do you have any suggestions?

Comment 2

[Nathan Froyd [:froydnj]]

Maybe ffs got removed in the android-16 sdk?  I see it in the r8e / android-14 directory on Linux.

What does find $ANDROID_NDK_HOME/r8e -name '*.h' | xargs fgrep 'ffs(' |grep arch-arm say for you?

Sorry, I forgot the most important part -- this is building for x86 devices.  (I have --target=i386-linux-android set; I've also tried both NDKs with i686-linux-android.)

Comment 5

[Nathan Froyd [:froydnj]]

/me applauds nalexander for displaying adaptability

Ah, so maybe ffs got removed in android-16?  I wonder if there's anything equivalent in strings.h now.

Comment 6

[Nick Alexander :nalexander [he/him]]

So, strings.h appears fine.  However,

/usr/local/Cellar/android-ndk/r8e-darwin-x86_64/platforms/android-9/arch-arm/usr/lib/libc.a

includes

ffs.o:
00000000 t $a
00000000 T ffs

But

/usr/local/Cellar/android-ndk/r8e-darwin-x86_64/platforms/android-9/arch-x86/usr/lib/libc.a

doesn't appear to include ffs at all.

Caused by:

Comment 9

[Eric Rescorla (:ekr)]

Note that on bug 1018665 I see it even building for ARM.

The problem is the android toolchain being broken for non-optimized builds using some builtins. It's not really related to arm vs. not.

Hmm.... It seems like this could be fixed by deactivating this change
for non-optimized builds, then, at least until the android toolchain
changes. No?


> It's not really related to arm vs. not.

OK, I was just filling in the details.

Comment 12

[Eric Rescorla (:ekr)]

This just tripped up :bbrittain too.

It seems like we should be able to build B2G in any reasonable build
configuration and non-optimized is one such configuration, so I'd
like to get this fixed. Any reason we shouldn't turn off this flag
for non-optimized builds?

Comment 15

[Mike Hommey [:glandium]]

The conflict in include/jemalloc/internal/util.h doesn't matter, it's for code that wasn't there in the version we have in-tree.
As for include/jemalloc/internal/jemalloc_internal_decls.h, on the File to patch prompt, enter include/jemalloc/internal/jemalloc_internal.h.in.

Comment 17

[Mike Hommey [:glandium]]

Forget it, that patch only helps halfway. The configure logic needs to be inverted to work.

Comment 20

[Eric Rescorla (:ekr)]

Should try both patches, or just the most recent patch in c19?

You need both. One is a plain cherry pick of the upstream patch, and the other an additional patch I sent upstream.

Already made it upstream:

:)

Regrettably, this seems not to fix the problem:

Try to use __builtin_ffsl if ffsl is unavailable

These patches look fine to me. I think the error in #c23 is because configure isn't being re-executed - those defines should always be present (if configure runs :) based on my understanding of these patches. ekr, can you confirm that a clobber fixes it?

It seems that ti still block fennec for x86 build with "ac_add_options --disable-optimize" in mozconfig.

And, build for arm is ok with same build environment.

My build environment:
Android NDK, r8e

Ubuntu 12.04 64-bit

mozconfig:
ac_add_options --enable-debug
ac_add_options --disable-optimize

# Add the correct paths here:
ac_add_options --with-android-ndk="$HOME/android-ndk-r8e"
ac_add_options --with-android-sdk="$HOME/adt-bundle-linux-x86_64/sdk/platforms/android-21"

# android options
ac_add_options --enable-application=mobile/android
ac_add_options --target=i386-linux-android

ac_add_options --with-ccache
ac_add_options --enable-debug-symbols

mk_add_options MOZ_OBJDIR=./x86-objdir-droid
