How long does gcc take to compile

We could build it ourselves, but the build is painful and I haven't yet gotten a completely working gcc build. Dan, Due to resource constraint we have no plan to introduce an additional release before the planned one. The solution I would suggest is to stay with the old version for a while, or build your own version.

May I know which part of building process is painful for you so that we can probably improve the how-to-build manual? Site Search User. Support forums. Share More actions Cancel.

Is this to be expected? Top replies. The updated script and binary package Hi Terry, We've just released q3-update. Thanks, Tejas. Up 0 Down Reply Accept answer Cancel. Sorry, where did you upload the test case? We saw the same issue. Xapian Olly Betts is using the compile farm for portability testing of Xapian. Buildroot PeterKorsgaard is running randpackageconfig builds of Buildroot on gcc Most day-to-day testing is on gcc10 and gcc The compile farm is a fantastic resource being provided thank you!

Libamqp EamonWalshe is using the compile farm to build and test libamqp with various gcc versions and different architectures. It consists of several parts "biosig for octave and matlab" provides functions for analysing the data in Octave and Matlab.

AloisSchloegl is using the compile farm for testing libbiosig on various platforms. Eventually, the testing will be extended to related projects NaN-toolbox for Octave with OpenMP enabled octave-nan The NaN-toolbox is a statistics and machine learning toolbox for the use in Octave and supports parallel data processing on shared-memory multi-core machines.

AloisSchloegl would like to compare different multi-core systems with the same performance test. Free Pascal nightly testsuite The Free Pascal compiler is a freeware pascal compiler. It has a testsuite with a number of machines performing compilation and testsuite runs every night. Results are visible on a special page. Wolfpack Empire Empire is a real time, multiplayer, Internet-based war game, and one of the oldest computer games still being played.

MarkusArmbruster uses the compile farm to ensure it stays portable. Dpkg GuillemJover uses the non-Linux hosts to port dpkg to those systems. It will prevent login on the management website, and also queue a task to remove the SSH keys from all farm machines.

Either wait for the cron job that does it, or run the task manually if it's urgent. Then, cleanup needs to be done manually if it's necessary. There are scripts to help SSH root on cfarm. Beware of offline machines, the script will of course not do anything on these. The output of the script is currently messy. Be patient. See "Cleanup data when a machine has a full disk" below for a strategy to cleanup. Add a new machine Preliminary work collect information about the hoster: organization name, should it appear on our website?

The meaning of "it" in the phrase "why waste time rebuilding it? See the new and more in depth answer below. The last two stages are far from a waste of time. Add a comment. Active Oldest Votes. If you prefer non-bootstrap for some reason, configure --disable-bootstrap. TylerH So thats all it is, a test? I can disable the whole process and to it in 1 pass?

Usually a new version of GCC produces better i. So the idea of the second build is to produce a compiler which runs faster, taking advantage of the better optimisations which are implemented in it itself. If you were confident that your existing compiler already compiles as well as possible, why are you attempting to upgrade? Conversely, if you are upgrading, why would you not want to take advantage of the upgrade?

The optional third compile, as the quoted answer says, is to verify that everything works as expected. Making that happen is not simple. Consider the variables in the target environment. Target operating system brand Operating system version Operating system settings Shell environment variables Availability of headers for inclusion Availability of libraries for linking Settings passed to the build process Architecture of the target processing unit Number of processing units Bus architecture Other characteristics of the execution model Mistakes the developers of the compiler might make Mistakes the person building the compiler might make In the GNU compiler tool set, and in many tarball distributions, the program "configure" attempts to produce a build configuration that adapts to as many of the permutations of these as is reasonably possible.

The interesting probabilistic consideration is this: If the result of using stage one's result to compile the compiler again equals exactly the result of using stage two's result to compile the compiler a third time, then both are likely correct for at least the features that the compiler's source code requires. Between the three reliability check points, most people are satisfied. Ensuring the compiler compiles itself consistently Other tests the compiler developers have put into their distribution The developer or system administrators source code domain is not broken by the upgrade On a mathematics side note, it is actually impossible to exhaustively test a compiler with the silicon and carbon available on planet earth.
