Show some of your APIs
Describe the current release and any notes about the current state of the project. Examples: currently compiles on your host machine, but is not cross-compiling for ARM, APIs are not set, feature not implemented, etc.
This project uses Embedded Artistry's standard Meson build system, and dependencies are described in detail on our website.
At a minimum you will need:
git-lfs
, which is used to store binary files in this repository- Meson is the build system
- Some kind of compiler for your target system.
- This repository has been tested with:
- gcc-7, gcc-8, gcc-9
- arm-none-eabi-gcc
- Apple clang
- Mainline clang
- This repository has been tested with:
This project stores some files using git-lfs
.
To install git-lfs
on Linux:
sudo apt install git-lfs
To install git-lfs
on OS X:
brew install git-lfs
Additional installation instructions can be found on the git-lfs
website.
The Meson build system depends on python3
and ninja-build
.
To install on Linux:
sudo apt-get install python3 python3-pip ninja-build
To install on OSX:
brew install python3 ninja
Meson can be installed through pip3
:
pip3 install meson
If you want to install Meson globally on Linux, use:
sudo -H pip3 install meson
This project uses git-lfs
, so please install it before cloning. If you cloned prior to installing git-lfs
, simply run git lfs pull
after installation.
This project is hosted on GitHub. You can clone the project directly using this command:
git clone --recursive [email protected]:embeddedartistry/project-skeleton.git
If you don't clone recursively, be sure to run the following command in the repository or your build will fail:
git submodule update --init
If Make is installed, the library can be built by issuing the following command:
make
This will build all targets for your current architecture.
You can clean builds using:
make clean
You can eliminate the generated buildresults
folder using:
make distclean
You can also use meson
directly for compiling.
Create a build output folder:
meson buildresults
And build all targets by running
ninja -C buildresults
Cross-compilation is handled using meson
cross files. Example files are included in the build/cross
folder. You can write your own cross files for your specific processor by defining the toolchain, compilation flags, and linker flags. These settings will be used to compile the project.
Cross-compilation must be configured using the meson command when creating the build output folder. For example:
meson buildresults --cross-file build/cross/gcc_arm_cortex-m4.txt
Following that, you can run make
(at the project root) or ninja
to build the project.
Tests will not be cross-compiled. They will only be built for the native platform.
Full instructions for building the project, using alternate toolchains, and running supporting tooling are documented in Embedded Artistry's Standardized Meson Build System on our website.
Link-time Optimization (LTO) can be enabled during the meson configuration stage by setting the built-in option b_lto
to true
:
meson buildresults -Db_lto=true
This can be combined with other build options.
The tests for this library are written with CMocka, which is included as a subproject and does not need to be installed on your system. You can run the tests by issuing the following command:
make test
By default, test results are generated for use by the CI server and are formatted in JUnit XML. The test results XML files can be found in buildresults/test/
.
The following meson project options can be set for this library when creating the build results directory with meson
, or by using meson configure
:
disable-builtins
will tell the compiler not to generate built-in functiondisable-stack-protection
will tell the compiler not to insert stack protection callsdisable-rtti
will disable RTTI for C++ projectsdisable-exceptions
will disable exceptions for C++ projectsenable-threading
can be used to control threaded targets and libc++ threading supportenable-pedantic
: Turn onpedantic
warningsenable-pedantic-error
: Turn onpedantic
warnings and errorshide-unimplemented-libc-apis
: Hides the header definitions for functions which are not actually implementedenable-gnu-extensions
will enable GNU libc extensions that are implemented in this library
The following options can be used to configure libc++
if used with this project:
libcxx-use-compiler-rt
libcxx-use-llvm-libunwind
libcxx-thread-library
libcxx-has-external-thread-api
libcxx-build-external-thread-api
libcxx-enable-chrono
libcxx-enable-filesystem
libcxx-enable-stdinout
libcxx-default-newdelete
libcxx-silent-terminate
libcxx-monotonic-clock
Options can be specified using -D
and the option name:
meson buildresults -Ddisable-builtins=false
The same style works with meson configure
:
cd buildresults
meson configure -Ddisable-builtins=false
Documentation can be built locally by running the following command:
make docs
Documentation can be found in buildresults/docs
, and the root page is index.html
.
