This project is part of the GNU Project.

Gnulib is intended to be the canonical source for most of the important "portability" and/or common files for GNU projects.  These are files intended to be shared at the source level; Gnulib is not a library meant to be installed and linked against.

While portability across operating systems is not one of GNU's primary goals, it has helped introduce many people to the GNU system, and is worthwhile when it can be achieved at a low cost.  This collection helps lower that cost.

There is no distribution tarball; developers should just grab source files from the repository.  Please see <http://www.gnu.org/software/gnulib/> for more details.

Gnulib features bitset, a module to support operations on lists of bits.

Its API is rich, and includes:

  • all the expected operations on single bit (set, toggle, test, etc.);
  • all the traditional binary bitwise operators (and, or, xor), often in two flavors (return new values, or perform in place); ...

There are three main motivations for using multiple threads in a program:

  • To get computational tasks done is less time, by using more than one CPU core at once.
  • For event handling. The older approach with signals and/or file descriptors in ...

Gnulib helps you write efficient algorithms
     posted by haible, Wed 23 Dec 2020 01:42:02 PM UTC - 0 replies

When writing algorithmic code, the classical approach is to define the data structures, write the algorithm, debug it, and then profile it. It often occurs that you notice that a certain list, set, or map can get large and that this costs CPU time. ...

Gnulib can help your C++ programs
     posted by haible, Wed 16 Dec 2020 08:31:05 PM UTC - 0 replies

Typically you test your programs on glibc systems.  Gnulib helps you to have the same program compile and work fine on other platforms, such as musl libc systems, macOS, FreeBSD, NetBSD, OpenBSD, AIX, Solaris, Cygwin, mingw, MSVC, Haiku, and even Minix and Android. ...
