Those are generally expected to be buildable without having to run autoconf, automake, gettext, etc. I'm pretty sure the GNU coding standards have required it since day 1. Automake generates tons of makefile real estate just for this. Generally speaking, removing the generated files (configure, aclocal.m4, Makefile.in, etc.) from git, while laudable, comes at the cost of three extra pieces of effort: 1) Unless a simple "autoreconf -is" is sufficient to do the job, a script like autogen.sh has to be prepared and put into the git 2) To the greatest extent feasible, maintainer rules have to be made to actually work to auto-update those generated files without the hassle of having to re-run autogen.sh 3) Preparing a release tarball is no longer quite as simple as just zipping up an other wise unchanged, fresh checkout (without the .git). That checkout will differ from a proper tarball in both directions: there will be files that should be in the tarball, but not in the checked-out copy, and there will be files in the check-out that should not got into the tarball. autogen.sh itself, and the special README telling people about it, are among the latter. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

It's a gross violation of the principle of least surprise. The standard way of building a Cygwin package from source is to download the source using Cygwin's setup program and then run cygport. That will work in this case too. (The cygport script runs autogen.sh.) If you choose instead to try to build from the source tarball without even looking at the cygport file, you get what you paid for. In the case of the Cygwin package, there is an alternative: You can follow the instructions at https://cygwin.com/faq.html#faq.programming.building-cygwin for building Cygwin from source. This explicitly mentions running autogen.sh. This only has to be done once, after first cloning Cygwin's git repo. After that, everything is updated as needed by the Makefile. Prior to running autogen.sh, there's no Makefile and no configure script. So I guess autogen.sh accomplishes something useful. Finally, I'd like to mention that it's extremely common for autotools-based packages to have an autogen script like Cygwin's (sometimes called bootstrap or bootstrap.sh).

[ANNOUNCEMENT] cygwin 3.3.0-0.1.9814cfd8f693 (TEST)
The following packages have been uploaded to the Cygwin distribution as test releases: * cygwin-3.3.0-0.1.9814cfd8f693 * cygwin-devel-3.3.0-0.1.9814cfd8f693 * cygwin-doc-3.3.0-0.1.9814cfd8f693 This release comes with an overhaul of the internal pipe code. In theory, there should be no user-visible changes except for bug fixes and performance improvements. But of course there will be new bugs. Please test! === What's new: --- - An IP-sampling profiler named 'profiler' has been added. It can be used to profile any Cygwin program along with any DLLs loaded. - A new tool 'gmondump' has been added. It can dump the raw information of any "gmon.out" file created by profiler, ssp, or use of the gcc/g++ option '-pg'. (Continue using gprof to get symbolic profile displays.) - New GNU-specific APIs, slated to become part of the next POSIX standard: pthread_cond_clockwait, pthread_mutex_clocklock, pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock, sem_clockwait. - New Solaris-specific APIs, slated to become part of the next POSIX standard: sig2str, str2sig. What changed: - - The speed argument to cfsetspeed(3) can now be a numerical baud rate rather than a Bnnn constant, as on Linux. Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248887.html - The internal implementation of pipes has been overhauled; this should result in improved performance. Addresses: https://cygwin.com/pipermail/cygwin/2021-August/249238.html Bug Fixes - - Fix values returned by select(2) for shutdown sockets. Addresses: https://cygwin.com/pipermail/cygwin-developers/2021-April/012092.html - Introduce a new hypotl(3) function not suffering unnecessary overflows. Addresses: https://cygwin.com/pipermail/cygwin/2021-April/248302.html - Fix path handling for paths spanning native symlinks. Addresses: https://cygwin.com/pipermail/cygwin/2021-April/248307.html - Fix tab position evaluation after console window resize. - Fix a regression in pseudo console handling, resulting in rlwrap not being able to start a new pseudo console. - Handle two race conditions in pseudo console usage. Addresses: https://cygwin.com/pipermail/cygwin/2021-April/248292.html - Fix a bug in recognizing a successful completion of connect(2) on a datagram socket. - Fix connect(2) when called with an address structure whose family is AF_UNSPEC. As specified by POSIX and Linux, this is allowed on datagram sockets, and its effect is to reset the socket's peer address. - Fix nanosleep(2) returning negative rem. NtQueryTimer appears to be able to return a negative remaining time (less than the timer resolution) for unsignalled timers. - Fix getifaddrs(3) returning address family 0 or IPv4 address 0. Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248970.html - Fix getaddrinfo(3) to return valid ai_socktype and ai_protocol values if the underlying GetAddrInfoW screws up. Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248985.html - Fix duplicate /proc/partitions entries and (presumably) duplicate PIDs in ps(1) output.
