Building and Testing the libc
|
|
=============================
|
|
|
|
Build modes
|
|
===========
|
|
|
|
The libc can be built and tested in two different modes:
|
|
|
|
#. **The overlay mode** - In this mode, one uses the static archive from LLVM's
|
|
libc along with the system libc. See :ref:`overlay_mode` for more details
|
|
on building and using the libc in this mode. You can only run the libc
|
|
unittests in this mode. To run them, one simply does:
|
|
|
|
.. code-block:: sh
|
|
|
|
$> ninja check-libc
|
|
|
|
Note that, unittests for only those functions which are part of the overlay
|
|
static archive will be run with the above command.
|
|
|
|
#. **The full build mode** - In this mode, the libc is used as the only libc
|
|
for the user's application. See :ref:`fullbuild_mode` for more details on
|
|
building and using the libc in this mode. Once configured for a full libc
|
|
build, you can run three kinds of tests:
|
|
|
|
#. Unit tests - You can run unittests by the command:
|
|
|
|
.. code-block:: sh
|
|
|
|
$> ninja check-libc
|
|
|
|
#. Integration tests - You can run integration tests by the command:
|
|
|
|
.. code-block:: sh
|
|
|
|
$> ninja libc-integration-tests
|
|
|
|
#. API verification test - See :ref:`api_test` for more information about
|
|
the API test. It can be run by the command:
|
|
|
|
.. code-block:: sh
|
|
|
|
$> ninja libc-api-test
|
|
|
|
Building with VSCode
|
|
====================
|
|
|
|
As a quickstart to using VSCode for development, install the cmake extension
|
|
and put the following in your settings.json file:
|
|
|
|
.. code-block:: javascript
|
|
|
|
{
|
|
"cmake.sourceDirectory": "${workspaceFolder}/llvm",
|
|
"cmake.configureSettings": {
|
|
"LLVM_ENABLE_PROJECTS" : "libc",
|
|
"LLVM_LIBC_FULL_BUILD" : true,
|
|
"LLVM_ENABLE_SPHINX" : true,
|
|
"LIBC_INCLUDE_DOCS" : true
|
|
}
|
|
}
|
|
|
|
Building with Bazel
|
|
===================
|
|
|
|
#. To build with Bazel, use the following command:
|
|
|
|
.. code-block:: sh
|
|
|
|
$> bazel build --config=generic_clang @llvm-project//libc/...
|
|
|
|
#. To run the unit tests with bazel, use the following command:
|
|
|
|
.. code-block:: sh
|
|
|
|
$> bazel test --config=generic_clang @llvm-project//libc/...
|
|
|
|
#. The bazel target layout of `libc` is located at: `utils/bazel/llvm-project-overlay/libc/BUILD.bazel <https://github.com/llvm/llvm-project/tree/main/utils/bazel/llvm-project-overlay/libc/BUILD.bazel>`_.
