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
Package | “debug” Flag Description |
---|---|
app-misc/rlwrap | Enable debug |
app-editors/nano | Enable debug messages and assert warnings. Note that these will all be sent straight to stderr rather than some logging facility. |
net-mail/vchkuser | Enables debug messages to syslog |
x11-misc/albert | Enable debugging informations |
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 |
dev-lang/crystal | Build each module as a separate object file. Speeds build up. |
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. |
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. |
sys-libs/glibc | When USE=hardened, allow fortify/stack violations to dump core (SIGABRT) and not kill self (SIGKILL) |
app-i18n/librime | Enable debugging (including logging of input of RIME input methods) |
app-portage/eix | Build with upstream's CXXFLAGS/LDFLAGS for debugging support; not recommended for normal use. |
dev-tcltk/expect-lite | pull in packages needed for runtime interactive debugger |
dev-haskell/pandoc-citeproc | Turn on debug tracing. |
games-emulation/zsnes | Enable the builtin debugger |
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-java/jfreesvg | Enable debugging during compilation. |
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 |
app-arch/innoextract | Enable debug logging and the --debug command-line option |
app-cdr/dvdisaster | Enable memory debugging. |
dev-haskell/chaselev-deque | Enable the extra internal checks. |
app-emulation/ski | enable extra binary emulation debugging via sys-libs/binutils-libs |
net-misc/chrony | Get DEBUG_LOG output from chronyd when passing -dd parameter |
media-tv/mythtv | Instructs Qt to use the 'debug' target |
net-vpn/wireguard-modules | Enable verbose debug reporting in dmesg of various WireGuard peer and device information. |
net-wireless/spectools | Build the raw output client for spectools. (for developers) |
dev-libs/openct | Add debug output to the driver library for pcsc-lite. |
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 <https://www.gentoo.org/proj/en/qa/backtraces.xml> |
sci-mathematics/agda | Enable debugging features that may slow Agda down. |
net-misc/ptpd | Enable debugging informations |
sys-auth/pam_u2f | Enable debug messages using the pam logging macros. |
sys-auth/pambase | Enable debug information logging on syslog(3) for all the modules supporting this in the system authentication and system login stacks. |
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 ;) |
www-client/chromium | Enable DCHECK feature with severity configurable at runtime. Mostly intended for debugging and development, NOT RECOMMENDED for general use. |
www-servers/monkeyd | Enable lots of debugging info |
x11-wm/e16 | Build libtrip debugging library |
