Segfault with mobile/xul

[Emmanuel Engelhart]

Hi,

Currently I'm trying to compile by myself FF mobile for Android using
mozilla-central.

I have achieved to compile & run on the Android emulator FF mobile with
the native UI (although it dies if I try to open a Web page).

But, I'm more interested in the mobile/xul code because I want to port a
XUL app. (currently running with xulrunner) to Android.

It seems to compile fine, but at the execution I have a sefault:

Does someone know why?

Sorry, I don't. Have you tried looking at the crash in GDB? Jim Chen made
doing this very easy.

hi Emmanuel, since you have been building both the native and XUL
versions of Firefox Mobile, you might want to delete your OBJDIR to
ensure your build does not inadvertently link incompatible object files.

Also, what Android NDK version are you using? I have seen similar
startup crashes when using NDK r7 (the current version). The crashes
"went away" when reverted to an older NDK version like r6b or r5c (which
is the version used on Mozilla's build machine).

Hi

Doug's assumption was right: I was using android-ndk-r7 and with
android-ndk-r6b it works!

Thank you for your help.
