Hello, As shown in the wiki articles shown below: https://wiki.gentoo.org/wiki//etc/portage/env https://wiki.gentoo.org/wiki/Knowledge_Base:Overriding_environment_variables_per_package
I made the following provisions to debug a program that was segfaulting on my system: (1). mkdir -p /etc/portage/env && cd /etc/portage/env (2). cat debug.conf CFLAGS="${CFLAGS} -ggdb" CXXFALGS="${CFLAGS}" FEATURES="nostrip" (3). cat package.env app-cdr/xfburn debug.conf (4). grep burn /etc/portage/package.use app-cdr/xfburn debug (5). FEATURES="nostrip" emerge -av xfburn I've had to define FEATURES on the command line as shown in (5), for nostrip to apply. For some reason, enabling the setting in /etc/portage/env/debug.conf did not seem to work for me. Where did I go wrong there? Thanks.
