-AGL CMake template
-==================
+# AGL CMake template
Files used to build an application, or binding, project with the
AGL Application Framework.
isn't recommended now to handle project build especially in a multiuser
project because CMake will not be aware of new or removed source files.
-You'll find simple usage example for different kind of target under the
-`examples` folder. More advanced usage can be saw with the
-[low-level-can-service](https://gerrit.automotivelinux.org/gerrit/apps/low-level-can-service)
-which mix external libraries, binding.

| \<root-path\> | - | Path to your project. Hold master CMakeLists.txt and general files of your projects. |
-| conf.d | \<root-path\> | Git submodule to app-templates AGL repository which provides CMake helpers macros library, and build scripts. config.cmake is a copy of config.cmake.sample configured for the projects. |
-| app-templates | conf.d | Holds examples files and cmake macros used to build packages |
+| conf.d | \<root-path\> | Holds needed files to build, install, debug, package an AGL app project |
+| app-templates | conf.d | Git submodule to app-templates AGL repository which provides CMake helpers macros library, and build scripts. config.cmake is a copy of config.cmake.sample configured for the projects. SHOULD NOT BE MODIFIED MANUALLY !|
+| autobuild | conf.d | Scripts generated from app-templates to build packages the same way for differents platforms.|
+| cmake | conf.d | Contains at least config.cmake file modified from the sample provided in app-templates submodule. |
+| wgt | conf.d | Contains at least config.xml.in template file modified from the sample provided in app-templates submodule for the needs of project (See config.xml.in.sample file for more details). |
| packaging | conf.d | Contains output files used to build packages. |
-| autobuild | conf.d | Scripts used to build packages the same way for differents platforms. |
| \<libs\> | \<root-path\> | External dependencies libraries. This isn't to be used to include header file but build and link statically specifics libraries. | Library sources files. Can be a decompressed library archive file or project fork. |
| \<target\> | \<root-path\> | A target to build, typically library, executable, etc. |
-Usage
-------
+## Usage
+
+### Initialization
To use these templates files on your project just install the reference files using
**git submodule** then use `config.cmake` file to configure your project specificities :
```bash
-git submodule add https://gerrit.automotivelinux.org/gerrit/apps/app-templatesconf.d/app-templates
+git submodule add https://gerrit.automotivelinux.org/gerrit/apps/app-templatesconf.d/app-templates conf.d/app-templates
+mkdir conf.d/cmake
+cp conf.d/app-templates/cmake/config.cmake.sample conf.d/cmake/config.cmake
```
-Specify manually your targets, you should look at samples provided in this
-repository to make yours. Then when you are ready to build, using `autobuild`
-that will wrap CMake build command:
+Edit the copied config.cmake file to fit your needs.
+
+### Update app-templates submodule
+
+You may have some news bug fixes or features available from app-templates
+repository that you want. To update your submodule proceed like the following:
```bash
-./conf.d/app-templates/autobuild/agl/autobuild.mk package
+git submodule update --remote
+git commit -s conf.d/app-templates
```
-Or with the classic way :
+This will update the submodule to the HEAD of master branch repository.
+
+You could just want to update at a specified repository tag or branch or commit
+, here are the method to do so:
```bash
-mkdir -p build
-cd build
-cmake .. && make
+cd conf.d/app-templates
+# Choose one of the following depending what you want
+git checkout <tag_name>
+git checkout --detach <branch_name>
+git checkout --detach <commit_id>
+# Then commit
+cd ../..
+git commit -s conf.d/app-templates
```
-### Create a CMake target
+### Create CMake targets
For each target part of your project, you need to use ***PROJECT_TARGET_ADD***
-to include this target to your project, using it make available the cmake
-variable ***TARGET_NAME*** until the next ***PROJECT_TARGET_ADD*** is invoked
-with a new target name. Be aware that ***populate_widget*** macro will also use
-***PROJECT_TARGET_ADD*** so ***TARGET_NAME*** will change after using
-***populate_widget*** macro.
+to include this target to your project.
+
+Using it, make available the cmake variable ***TARGET_NAME*** until the next
+***PROJECT_TARGET_ADD*** is invoked with a new target name.
So, typical usage defining a target is:
#### config.xml.in file
-To build a widget you need to configure file _config.xml_. This repo
-provide a simple default file _config.xml.in_ that will be configured using the
-variable set in _config.cmake_ file.
+To build a widget you need a _config.xml_ file describing what is your apps and
+how Application Framework would launch it. This repo provide a simple default
+file _config.xml.in_ that should work for simple application without
+interactions with others bindings.
+
+It is recommanded that you use the sample one which is more complete. You can
+find it at the same location under the name _config.xml.in.sample_ (stunning
+isn't it). Just copy the sample file to your _conf.d/wgt_ directory and name it
+_config.xml.in_, then edit it to fit your needs.
> ***CAUTION*** : The default file is only meant to be use for a
> simple widget app, more complicated ones which needed to export
#### Using cmake template macros
-To leverage all macros features, you have to specify ***properties*** on your
-targets. Some macros will not works without specifying which is the target type.
+To leverage all cmake templates features, you have to specify ***properties***
+on your targets. Some macros will not works without specifying which is the
+target type.
As the type is not always specified for some custom targets, like an ***HTML5***
application, macros make the difference using ***LABELS*** property.
***build_widget*** that make an archive from the populated widget tree using the
`wgtpkg-pack` Application Framework tools.
-Macro reference
---------------------
+## Macro reference
### PROJECT_TARGET_ADD
project_subdirs_add("[0-9]-*")
```
-### project_targets_populate
+## Autobuild script usage
-Macro use to populate widget tree. To make this works you have to specify some
-properties to your target :
+### Generation
-* LABELS : specify *BINDING*, *HTDOCS*, *EXECUTABLE*, *DATA*
-* PREFIX : must be empty **""** when target is a *BINDING* else default prefix
- *lib* will be applied
-* OUTPUT_NAME : Name of the output file generated, useful when generated file
- name is different from `${TARGET_NAME}`
+To be integrated in the Yocto build workflow you have to generate `autobuild`
+scripts using _autobuild_ target.
-Always specify `populate_widget()` macro as the last statement, especially if
-you use ${TARGET_NAME} variable. Else variable will be set at wrong value with
-the **populate_** target name.
-
-Usage :
+To generate those scripts proceeds:
-```cmake
-project_targets_populate()
+```bash
+mkdir -p build
+cd build
+cmake .. && make autobuild
```
-### project_package_build
+You should see _conf.d/autobuild/agl/autobuild_ file now.
-Use at project level, to gather all populated targets in the widget tree plus
-widget specifics files into a **WGT** archive. Generated under your `build`
-directory :
+### Available targets
-Usage :
+Here are the available targets available from _autobuild_ scripts:
-```cmake
-project_package_build()
-```
+- **clean** : clean build directory from object file and targets results.
+- **distclean** : delete build directory
+- **configure** : generate project Makefile from CMakeLists.txt files.
+- **build** : compile all project targets.
+- **package** : build and output a wgt package.
+
+You can specify variables that modify the behavior of compilation using
+the following variables:
+
+- **CONFIGURE_ARGS** : Variable used at **configure** time.
+- **BUILD_ARGS** : Variable used at **build** time.
+- **DEST** : Directory where to output ***wgt*** file.
-### project_closing_message
+Variable as to be in CMake format. (ie: BUILD_ARGS="-DC_FLAGS='-g -O2'")
-Will display the closing message configured in `config.cmake` file. Put it at
-the end of your project CMake file.

+Usage example:
