            how do I remove `GLIBC_2.27' requirement at compile time?
            Asked 2019-Dec-12 at 07:09

            I've been using a docker image for c++ compilation. It's based on Ubuntu 18.04. When I attempt to run on some Ubuntu 16 systems, I get this message:

            /lib/x86_64-linux-gnu/ version `GLIBC_2.27' not found

            I'll post the full ldd output below. I like using the newer compiler. I would prefer to not compile with an older Linux base image (but I will if necessary). I statically link most libraries, but I haven't been statically linking glibc. A number of web sources recommend against that. Is there some way I can tell my newer compiler (gcc 7.3) to not require the newer glibc? ldd -v output:



            Answered 2019-Mar-07 at 20:55

            You need to build against an older glibc version. Very few distributions, if any, support that out of the box. The only practical way at the moment is to build on an older distribution.

            Some distributions with long support cycles offer newer GCC versions that do not require newer system compilers (such as Developer Toolset, which is available for CentOS and Red Hat Enterprise Linux).



            understanding ldd verbose: what are the multiple versions?
            Asked 2019-Mar-08 at 05:09

            When I run ldd in verbose mode, I get output like that below. What does it mean when multiple versions are listed? Does that mean that any of those versions workable, or that it needs all those versions?



            Answered 2019-Mar-08 at 05:09

            What does it mean when multiple versions are listed?

            It means that your binary references symbols with these versions. See also this and this answer.

            Does that mean that any of those versions workable, or that it needs all those versions?

            The latter. Or rather, it needs a library that provides all of these symbols, which generally means GLIBC_2.27 or later for GLIBC, and GCC_4.2.0 or later for libgcc.

            Install lbrycrd

            Latest binaries are available from There is no installation procedure; the CLI binaries will run as-is and will have any uncommon dependencies statically linked into the binary. The QT GUI is not supported. LBRYcrd is distributed as a collection of executable files; traditional installers are not provided.


            Contributions to this project are welcome, encouraged, and compensated. For more details, see We follow the same coding guidelines as documented by Bitcoin Core, see here. To run an automated code formatting check, try: git diff -U0 master -- '*.h' '*.cpp' | ./contrib/devtools/ -p1. This will check any commits not on master for proper code formatting. We try to avoid altering parts of the code that is inherited from Bitcoin Core unless absolutely necessary. This will make it easier to merge changes from Bitcoin Core. If commits are expected not to be merged upstream (i.e. we broke up a commit from Bitcoin Core in order to use a single feature in it), the commit message must contain the string "NOT FOR UPSTREAM MERGE". The master branch is regularly built and tested, but is not guaranteed to be completely stable. Releases are created regularly to indicate new official, stable release versions. 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. Developers are strongly encouraged to write unit tests for new code and to submit new unit tests for old code. Unit tests are compiled by default and can be run with src/test/test_lbrycrd. The Travis CI system makes sure that every pull request is built, and that unit and sanity tests are automatically run. See
