5b93e65f6abfd174a56cf50c952ca5d5c3833859 build: remove D__STDC_FORMAT_MACROS from CPPFLAGS (fanquake) dbfca4a815d2dbef69f3b634c24b875bc1d22afc build: require glibc 2.18+ for release builds (fanquake) Pull request description: This increases our runtime glibc requirement from 2.17 to 2.18. From what I can see the only platform this drops release support for is CentOS 7, which reached the end of it's "full update" support at the [end of 2020](https://wiki.centos.org/About/Product). It does receive maintenance updates until 2024, however I don't think supporting glibc 2.17 until 2024 is realistic. It was mentioned in #22405 that our 2.17 requirement could be a bit excessive, and I tend to agree, however without a good reason to require an even newer version, I think a move from 2.17 -> 2.18 is sufficient for now. That means we get a glibc with "proper" support for `thread_local` (see below), as well as avoid having to patch dependencies to retain glibc compatibility (see #23489). Note that anyone wanting to self-compile and target a glibc 2.17 runtime could currently build with `--disable-threadlocal`. However we wouldn't make any guarantees on how long that workaround might exist for. glibc 2.18 was released in August 2013: https://sourceware.org/legacy-ml/libc-alpha/2013-08/msg00160.html. > Add support for calling C++11 thread_local object destructors on thread and program exit. This needs compiler support for offloading C++11 destructor calls to glibc. The last time we increased our runtime glibc requirement for release builds was in #17538 (0.20 release), where we moved from a 2.11 requirement to 2.17.

What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master branch is regularly built (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be
completely stable. Tags are created
regularly from release branches to indicate new official, stable release versions of Bitcoin Core.
The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.
The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled in configure) with: make check. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
