PackagesEnable 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-arch/innoextract | Enable debug logging and the --debug command-line option |
| app-cdr/dvdisaster | Enable memory debugging. |
| 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-emulation/ski | enable extra binary emulation debugging via sys-libs/binutils-libs |
| app-i18n/librime | Enable debugging (including logging of input of RIME input methods) |
| app-misc/rlwrap | Enable debug |
| app-portage/eix | Build with upstream's CXXFLAGS/LDFLAGS for debugging support; not recommended for normal use. |
| dev-haskell/atomic-primops | Enable extra internal checks. |
| dev-haskell/text-short | Enable runtime-checks via 'assert' |
| dev-lang/crystal | Build each module as a separate object file. Speeds build up. |
| 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/zig | Build with debug extensions enabled. |
| 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. |
| dev-perl/perl-headers | Add source locations in generated .ph files to assist with debugging when errors occur |
| dev-tcltk/expect-lite | pull in packages needed for runtime interactive debugger |
| 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. |
| 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 |
| media-tv/mythtv | Instructs Qt to use the 'debug' target |
| net-misc/chrony | Get DEBUG_LOG output from chronyd when passing -dd parameter |
| net-misc/ptpd | Enable debugging informations |
| net-p2p/transmission | Enable assertions |
| net-vpn/ovpn-dco | Enable debug output in dmesg |
| net-vpn/wireguard-modules | Enable verbose debug reporting in dmesg of various WireGuard peer and device information. |
| 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-auth/pam_u2f | Enable debug messages using the pam logging macros. |
| 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 ;) |
| sys-devel/gcc | Enables GCC's 'checking' facility via --enable-checking=yes,extra,rtl. This adds checks to various compiler passes for integrity and input validation. This can help catch possible miscompilations early as well as latent bugs which could become real problems in future, but at the cost of slower compile times when using GCC. Unrelated to backtraces. |
| sys-libs/glibc | When USE=hardened, allow fortify/stack violations to dump core (SIGABRT) and not kill self (SIGKILL) |
| 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. |
| www-client/chromium | Enable DCHECK feature with severity configurable at runtime. Mostly intended for debugging and development, NOT RECOMMENDED for general use. |
| www-servers/nginx | Enable support for debugging log |
| x11-wm/e16 | Build libtrip debugging library |
