770900 - No debugging symbols generated for Firefox on x86-64 Linux (with all relevant options on)

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[Shlomi Fish]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120616022601

Steps to reproduce:

I've ran  "make -f client.mk" and "make -f client.mk install" with this .mozconfig:

<<<
. $topsrcdir/browser/config/mozconfig
export LDFLAGS="-Wl,--no-keep-memory"
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/ff-dbg
ac_add_options --disable-optimize
ac_add_options --enable-debug
ac_add_options --enable-tests
ac_add_options --enable-debug-symbols
ac_add_options --prefix="$HOME/apps/net/www/firefox-hg"
>>>

On Mageia Linux 2 x86-64 on my Acer laptop. I've based my build on the mozilla-central revision 98255:87db9617a885e7bac31d9e724facf9f0ad3a6c50 with a small patch to get the build to work here.


Actual results:

When running gdb against firefox or firefox-bin, the stack trace is full of question marks instead of symbols:

Expected results:

There should be debug symbols.

The symbols are stripped when installing.

You can either ask the build system not to strip when installing with
  make -f client.mk install PKG_SKIP_STRIP=1

Or point gdb to the symbols location (set debug-file-directory)

(You can point it to objdir/dist/bin)

Attachment: The Patch I used.

This is the patch I used to get the trunk to build. Part of it is based on the recommendation in:

https://bugzilla.mozilla.org/show_bug.cgi?id=759320

I suggest adding the part with the " | xargs rm" ==> " | xargs rm -f".
