CONTINUOUS INTEGRATION SCRIPTS
==============================
# CONTINUOUS INTEGRATION SCRIPTS
Environment Variables Used in Build Scripts
-------------------------------------------
## Environment Variables Used in Build Scripts
- `NODE_LABELS`: the variable defines a list of OS properties. The set values are used by the
build scripts to select proper behavior for different OS.
- `NODE_LABELS`: space-separated list of platform properties. The included values are used by
the build scripts to select the proper behavior for different operating systems and versions.
The list should include at least `[OS_TYPE]`, `[DISTRO_TYPE]`, and `[DISTRO_VERSION]`.
The list should normally contain `[OS_TYPE]`, `[DISTRO_TYPE]`, and `[DISTRO_VERSION]`.
Possible values for Linux:
Example values:
* `[OS_TYPE]`: `Linux`
* `[DISTRO_TYPE]`: `Ubuntu`
* `[DISTRO_VERSION]`: `Ubuntu-16.04`, `Ubuntu-18.04`
- `[OS_TYPE]`: `Linux`, `OSX`
- `[DISTRO_TYPE]`: `Ubuntu`, `CentOS`
- `[DISTRO_VERSION]`: `Ubuntu-16.04`, `Ubuntu-18.04`, `CentOS-8`, `OSX-10.14`, `OSX-10.15`
Possible values for OS X / macOS:
* `[OS_TYPE]`: `OSX`
* `[DISTRO_TYPE]`: `OSX` (can be absent)
* `[DISTRO_VERSION]`: `OSX-10.11`, `OSX-10.12`, `OSX-10.13`
- `JOB_NAME`: optional variable to define type of the job. Depending on the defined job type,
- `JOB_NAME`: optional variable that defines the type of build job. Depending on the job type,
the build scripts can perform different tasks.
Possible values:
* empty: default build process
* `code-coverage` (Ubuntu Linux is assumed): debug build with tests and code coverage analysis
* `limited-build`: only a single debug build with tests
- empty: default build task
- `code-coverage`: debug build with tests and code coverage analysis (Ubuntu Linux is assumed)
- `limited-build`: only a single debug build with tests
- `CACHE_DIR`: the variable defines a path to folder containing cached files from previous builds,
e.g., a compiled version of ndn-cxx library. If not set, `/tmp` is used.
- `CACHE_DIR`: directory containing cached files from previous builds, e.g., a compiled version
of ndn-cxx. If not set, `/tmp` is used.
- `WAF_JOBS`: number of parallel build jobs used by waf, defaults to 1.
- `WAF_JOBS`: number of parallel build threads used by waf, defaults to 1.

The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free

When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
To protect your rights, we need to prevent others from denying you

For example, if you distribute copies of such a program, whether
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.

patents cannot be used to render the program non-free.
