8f15a317602727d24f60d0bbf43f851b33df3228 doc: add glibc 2.17 requirement to release-notes (fanquake) 16a7be1663b02ddefa1e4f0309be49b725ffb388 build: Bump minimum versions in symbol checker (Wladimir J. van der Laan) b77d5ad59fb9f3f26d919ee6c33ae732382de504 build: Disallow dynamic linking against c++ library (Wladimir J. van der Laan) Pull request description: Closes: #17525. Taken over from #17531. Debian 8 (Jessie) has: - g++ version 4.9.2 - libc version 2.19 CentOS 7 has: - g++ version 4.8.5 - libc version 2.17 Ubuntu 16.04.4 (Xenial, oldest supported Ubuntu) has: - g++ version 5.3.1 - libc version 2.23.0 Taking the minimum of these as our target. According to [GNU ABI document](https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html) this corresponds to: - GCC 4.8.5: GCC_4.8.0 - (glibc) GLIBC_2_17 This also contains a (long needed) commit to disallow dynamic linking to stdc++, as our releases statically link against that.

Bitcoin Core integration/staging tree
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.
For more information, as well as an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the original whitepaper.
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 and tested, but is not guaranteed to be
completely stable. Tags are created
regularly to indicate new official, stable release versions of Bitcoin Core.
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, that are run automatically on the build server.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The Travis CI system makes 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.
Translators should also subscribe to the mailing list.
