781668 - No more symbols in gdb with fennec build

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Nicolas Silva [:nical]]

With jimDB I have no symbols when debugging fennec.

jrmuizel updated his tree as well today (august 9, 2012) and since then he has no symbol in gdb either.

debugging without symbols is recipe for sadness, therefore we need to fix this.

Are you saying it was working until recently?

What does "info sharedlibrary" say, at the gdb prompt?

Yeah. "info sharedlibrary" says in the appropriate column "No"

Are you running Jelly Bean? There's a bug in the Jelly Bean linker that prevents GDB from properly attaching to the linker. http://code.google.com/p/android/issues/detail?id=34856

I'm going to try the patch in that bug. Also, running "sharedlibrary" manually in GDB should get the symbols back.

I was seeing this on a Nexus S running Gingerbread.
