Starting it up reports the following error:

Release/beta/aurora/nightly work fine presumably because they were built with the 4.4.3 toolchain.

Using "nm" on the libmozglue.so files extracted from the various APKs seems to confirm that the 4.4.3 builds have the symbols defined, e.g:

00021450 A __exidx_end
00021358 A __exidx_start
         w __gnu_Unwind_Find_exidx

whereas the libmozglue.so from my local 4.6.3 build doesn't have symbols.

Attachment: Link libmozglue without -nostartfiles on android

I think this would work. Will r? when confirmed to work.

Comment 2

[Kartikaya Gupta (email:[e-mail])]

That patch doesn't seem to fix the problem. I still get the same behaviour on startup:

In case it helps, this is what gets run when I do a make -C objdir/mozglue/build after touching that makefile.

Comment 3

[Mike Hommey [:glandium]]

Can you add a DSO_LDOPTS += -Wl,--verbose and attach the resulting output?

Comment 4

[Mike Hommey [:glandium]]

I can't reproduce with either ndk r8b or r8c, what are you using?

Comment 5

[Mike Hommey [:glandium]]

I can't reproduce with an old build of the ndk r6b with gcc 4.6.3 either.

Comment 6

[(inactive) Jim Chen [:jchen] [:darchons]]

I reproduced with Mozilla-repackaged NDK r7 using gold.

I couldn't reproduce with stock NDK r6b, stock NDK r8b using ld/bfd, and stock NDK r8b using gold.

Comment 7

[Mike Hommey [:glandium]]

Looks like we should deploy r8c on the build slaves, then.

Comment 8

[Kartikaya Gupta (email:[e-mail])]

Attachment: Output with verbose

This is with DSO_LDOPTS += -Wl,--verbose

Comment 9

[Kartikaya Gupta (email:[e-mail])]

Verified that this works fine with r8c and gold as well. Seems to just be an issue with the mozilla-repackaged NDK, then.
