1. Build testing with GitHub Actions
|
|
------------------------------------
|
|
|
|
We test master branch in https://github.com/linux-test-project/ltp/actions[GitHub Actions]
|
|
to ensure LTP builds on various distributions including old, current and bleeding edge.
|
|
We test both gcc and clang toolchains, various architectures with cross-compilation.
|
|
For list of tested distros see
|
|
https://github.com/linux-test-project/ltp/blob/master/.github/workflows/ci.yml[.github/workflows/ci.yml].
|
|
|
|
|
|
NOTE: GitHub Actions does only build testing, passing the CI means only that
|
|
the test compiles fine on variety of different distributions and releases.
|
|
GitHub Actions also uses the latest distribution image of a particular release.
|
|
|
|
1.1 Oldest tested distributions

|
|
|==============================================================
|
|
| Distro | kernel | glibc | gcc | clang
|
|
| CentOS 7 | 3.10 | 2.17 | 4.8.5 | -
|
|
| Ubuntu 18.04 LTS bionic | 4.15 | 2.27 | 7.3.0 | -
|
|
| Debian 10 oldstable (buster) | 4.19.37 | 2.28 | 8.3.0 | 7.0
|
|
|==============================================================
|
|
|
|
Older distributions are not officially supported, which means that it
|
|
may or may not work. It all depends on your luck. It should be possible
|
|
to compile latest LTP even on slightly older distributions than we
|
|
support with a few manual tweaks, e.g. disabling manually tests for
|
|
newly added syscalls, etc. Trivial fixes/workarounds may be accepted,
|
|
but users are encouraged to move to a newer distro.
|
|
|
|
If latest LTP cannot be compiled even with some amount of workarounds,
|
|
you may result to older LTP releases, however these are _not_ supported
|
|
in any way. Also if you are trying to run LTP on more than 10 years old
|
|
distribution you may as well reconsider you life choices.

1.3 Minimal supported kernel version
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Minimal supported kernel version is 3.10.
|
|
|
|
1.4 Supported libc

[align="center",options="header"]
|
|
|==================================
|
|
| Libc | Note
|
|
| https://www.gnu.org/software/libc/[GNU C Library (glibc)] | Targetted libc, tested both compilation and actual test results.
|
|
| https://uclibc-ng.org/[uClibc-ng] | Although not being tested it should work as well as it attempt to maintain a glibc compatible interface.
|
|
| https://www.uclibc.org/[uClibc] | Older https://www.uclibc.org/[uClibc] might have problems.
|
|
| https://musl.libc.org/[musl] | Not yet fully supported (see
|
|
https://github.com/linux-test-project/ltp/blob/master/ci/alpine.sh[CI script]
|
|
for list of files which need to be deleted in order to compile under musl).

1.5 Used C standard
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
LTP compiles with '-std=gnu99'.
