Introduction

This package installs a C11 language library; it implements an interface to non-local exits, which is somewhat similar to exceptions handling. The library targets POSIX systems.

The package uses the GNU Autotools and it is tested, using Travis CI, on both Ubuntu GNU+Linux systems and OS X systems.

Install

To install from a proper release tarball, do this:

$ cd ccexceptions-0.1.0
$ mkdir build
$ cd build
$ ../configure
$ make
$ make check
$ make install

to inspect the available configuration options:

$ ../configure --help

The Makefile is designed to allow parallel builds, so we can do:

$ make -j4 all && make -j4 check

which, on a 4-core CPU, should speed up building and checking significantly.

The Makefile supports the DESTDIR environment variable to install files in a temporary location, example: to see what will happen:

$ make -n install DESTDIR=/tmp/ccexceptions

to really do it:

$ make install DESTDIR=/tmp/ccexceptions

After the installation it is possible to verify the installed library against the test suite with:

$ make installcheck

From a repository checkout or snapshot (the ones from the GitHub site): we must install the GNU Autotools (GNU Automake, GNU Autoconf, GNU Libtool), then we must first run the script "autogen.sh" from the top source directory, to generate the needed files:

$ cd ccexceptions
$ sh autogen.sh

notice that autogen.sh will run the programs autoreconf and libtoolize; the latter is selected through the environment variable LIBTOOLIZE, whose value can be customised; for example to run glibtoolize rather than libtoolize we do:

$ LIBTOOLIZE=glibtoolize sh autogen.sh

After this the procedure is the same as the one for building from a proper release tarball, but we have to enable maintainer mode:

$ ../configure --enable-maintainer-mode [options]
$ make
$ make check
$ make install

Usage

Read the documentation.

IMPORTANT To use the library we must enable the POSIX features when including the standard header files; so either we include ccexceptions.h as first header, or we include the following definitions before including all the header files:

#define _POSIX_C_SOURCE 200809L

Credits

The stuff was written by Marco Maggi. If this package exists it's because of the great GNU software tools that he uses all the time.

Badges and static analysis

Travis CI

Travis CI is a hosted, distributed continuous integration service used to build and test software projects hosted at GitHub. We can find this project's dashboard at:

https://travis-ci.org/marcomaggi/ccexceptions

Usage of this service is configured through the file .travis.yml and additional scripts are under the directory meta/travis-ci.

Clang's Static Analyzer

The Clang Static Analyzer is a source code analysis tool that finds bugs in C, C++, and Objective-C programs. It is distributed along with Clang and we can find it at:

http://clang-analyzer.llvm.org/

Usage of this service is implemented with make rules; see the relevant section in the file Makefile.am.

Codecov

Codecov is a service providing code coverage reports. We can find this project's dashboard at:

https://codecov.io/gh/marcomaggi/ccexceptions

Usage of this service is implemented through direct interface between GitHub and Codecov sites; it configured through the file codecov.yml and appropriate entries in Travis CI's matrix of builds.

Codacy

Codacy is an online service providing code review. We can find this project's dashboard at:

https://www.codacy.com/app/marcomaggi/ccexceptions

Usage of this service is implemented through direct integration between GitHub and Codacy sites.
