debug

Global USE flag

Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces


Packages describing “debug” as local USE flag

Package “debug” Flag Description
app-arch/innoextract Enable debug logging and the --debug command-line option
app-i18n/librime Enable debugging (including logging of input of RIME input methods)
dev-java/jfreesvg Enable debugging during compilation.
dev-tcltk/expect-lite pull in packages needed for runtime interactive debugger
sys-libs/glibc When USE=hardened, allow fortify/stack violations to dump core (SIGABRT) and not kill self (SIGKILL)
app-editors/nano Enable debug messages and assert warnings. Note that these will all be sent straight to stderr rather than some logging facility.
app-portage/eix Build with upstream's CXXFLAGS/LDFLAGS for debugging support; not recommended for normal use.
dev-lang/spidermonkey Enable assertions to allow for easier debugging of programs that link to spidermonkey -- note this will often crash software on regular end-user systems
sys-auth/pam_u2f Enable debug messages using the pam logging macros.
www-servers/monkeyd Enable lots of debugging info
dev-perl/perl-headers Add source locations in generated .ph files to assist with debugging when errors occur
dev-util/google-perftools Build a set of libraries with debug support (so-called debugalloc). These are available by default but are not needed unless you're actually developing using tcmalloc.
app-misc/rlwrap Enable debug
games-action/dxx-rebirth Enable various debugging code paths and sanity checks, not just output. Some of these checks date back to the retail build, and choke on some custom levels because the game was never coded to sufficiently distrust inputs
sys-block/parted Enable debugging as encouraged by upstream: [The default configuration] includes --enable-debug (by default), which contains many assertions. Obviously, these "waste" space, but in the past, they have caught potentially dangerous bugs before they would have done damage, so we think it's worth it. Also, it means we get more bug reports ;)
app-cdr/dvdisaster Enable memory debugging.
net-vpn/wireguard-modules Enable verbose debug reporting in dmesg of various WireGuard peer and device information.
app-emulation/ski enable extra binary emulation debugging via sys-libs/binutils-libs
sys-kernel/dracut Module installing additional tools like strace, file editor, ssh and more
sys-process/fcron Enable debug code and output. Since version 3.0.5 this will no longer force foreground execution, and fcron will be able to run as a service properly.
dev-lang/crystal Build each module as a separate object file. Speeds build up.
dev-libs/boost Build and install only the debug version of the Boost libraries. Only enable this flag if you're developing against boost.
dev-libs/libevent Support for running in debug mode
dev-libs/openct Add debug output to the driver library for pcsc-lite.
net-wireless/spectools Build the raw output client for spectools. (for developers)
gui-wm/wayfire add debugging symbols for error reporting. DISABLE ALL SYSTEM USE FLAGS BEFORE REPORTING BUGS.
games-board/teg Turn on debugging
games-emulation/zsnes Enable the builtin debugger
x11-wm/e16 Build libtrip debugging library
net-misc/ntpclient Enable analysis code path and debugging of NTP protocol.
mail-filter/dspam Enable debugging support (don't enable this unless something needs testing!)
media-tv/mythtv Instructs Qt to use the 'debug' target
net-misc/ptpd Enable debugging informations
net-mail/vchkuser Enables debug messages to syslog
net-misc/stargazer Enable extra debug codepaths, like asserts and extra output.
sci-libs/dealii Build an additional debug library with extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see <http://www.gentoo.org/proj/en/qa/backtraces.xml>
sys-apps/timer_entropyd Enable printf debugging and logging to the syslog at DEBUG level
sys-auth/pambase Enable debug information logging on syslog(3) for all the modules supporting this in the system authentication and system login stacks.
