Yes, use the procedure I gave you in
http://permalink.gmane.org/gmane.linux.alsa.devel/88753 . I used it a
few weeks ago to debug alsa-lib in gdb.

Just tested now, ubuntu 10.04:

sudo apt-get build-dep libasound2
apt-get source libasound2
cd alsa-lib-1.0.22/
export DEB_BUILD_OPTIONS=nostrip,noopt
dpkg-buildpackage -rfakeroot -uc -us

Simple check while the compilation runs shows the gcc compiler is called
with -g -O0 params.

In a few minutes fresh .debs were waiting for me in the parent
directory, to be installed with dpkg -i libasound*deb and stepped with gdb.

With regards,


Pavel.
