[[package-reference]]
+package+ Reference
~~~~~~~~~~~~~~~~~~~
The list of variables that can be set in a +Makefile+ to give metadata
information is:
* +PKG_NAME+, mandatory, must contain the name of the package.
* +PKG_VERSION+, mandatory, must contain the version of the package.
* +PKG_RELEASE+, mandatory, must contain the OpenADK specific release of the package.
* +PKG_HASH+, mandatory, must contain the SHA256 hash of the package, will be used
to check if a download of a package is complete.
* +PKG_SECTION+, mandatory, must contain the OpenADK specific section, see package/section.lst.
* +PKG_RELEASE+, mandatory, must contain an one line summary of the package description.
* +PKG_URL+, optional, may contain the url to the homepage of the package
* +PKG_SITES+, mandatory, must contain the download url for the package, multiple entries
with space separated, are allowed. Only HTTP/HTTPS or FTP URLS are allowed.
A backup site (http://www.openadk.org/distfiles) is always used, if the package site is
not available. There is no direct support for cvs/svn/git/hg/bzr repositories, because
building OpenADK behind a HTTP proxy should be working without any configuration hassle.
There are also some predefined mirror sites in +mk/mirrors.mk+,
which can be used.
Example: PKG_SITES:= +${MASTER_SITE_GNU:=foo/}+
* +DISTFILES+ optional, may contain the name of the tarball of
the package. If +DISTFILES+ is not specified, it defaults to +PKG_NAME-PKG_VERSION.tar.xz+.
Example: DISTFILES= +${PKG_NAME}${PKG_VERSION}.tar.gz+
* +NO_DISTFILES+ optional, may be set to 1, to disable fetching of any archives.
Provide the source code for the package in +package/<pkgname>/src+, which will be
automatically copied to the WRKBUILD/WRKSRC directory.
* +PKG_BUILDDEP+ optional, lists the build time dependencies (in terms of package
directory name, see +package/+) that are required for the current target package to
compile. These dependencies are guaranteed to be compiled and
installed before the configuration of the current package starts.
* +PKG_DEPENDS+ optional, lists the runtime dependencies that are required to
run the software package on the target. It contains a list of package names,
which might be different to the package directory name. See what is used
in PKG_template, to find out the package name used here.
* +PKG_KDEPENDS+ optional, lists the kernel module dependencies that are required to
run the software package on the target. It contains a list of kernel module names
in lower case as used in +target/linux/config+. (use minus instead of underscores)
* +PKG_NEEDS+ optional, lists the features that are required to build or
run the software package on the target. It contains a list of keywords.
Supported are +threads+ +rt+ +c+++
* +PKG_NOPARALLEL+ optional, may be set to 1, to disable parallel building of the
package via make -jn, n=4 is default, but can be changed in +Global Settings+ in the
menu based configuration.
* +PKG_OPTS+ optional, may be set to following values:
+dev+ create a development package automatically, containing header files and +.pc+ files.
Only useful for library packages, when you want to compile on the target.
+devonly+ only creates a development package with header files, normally not needed on
the target.
+noscripts+ do not automatically install *-config and other build related scripts into
+STAGING_TARGET_DIR/scripts+, required for automake/autoconf package
+noremove+ do not automatically remove package files from +STAGING_TARGET_DIR+
The recommended way to define these variables is to use the following
syntax:
----------------------
PKG_VERSION:= 2.11
----------------------
Or for lines longer than 80 characters use:
----------------------
PKG_DEPENDS:= foo bar baz
PKG_DEPENDS+= muh maeh
----------------------
The variables that define what should be performed at the
different steps of the configure, build and install process.
* +CONFIG_STYLE+ manual, auto, minimal, basic, perl or cmake
* +CONFIGURE_ARGS+ add --enable-foo/--disable-foo to configure
* +CONFIGURE_ENV+ add additional environment variables to configure step
* +HOST_STYLE+ either manual or auto
* +HOST_CONFIGURE_ARGS+ add --enable-foo/--disable-foo to host configure
* +HOST_CONFIGURE_ENV+ add additional environment variables to the host configure step
* +AUTOTOOL_STYLE+ either autoreconf, autoconf or bootstrap
* +BUILD_STYLE+ either manual or auto
* +MAKE_ENV+ add additional variables to build step
* +MAKE_FLAGS+ add additinal make flags to build step
* +FAKE_FLAGS+ add additional make flags to fake install step
* +XAKE_FLAGS+ add additional make flags to build and fake install step
* +INSTALL_STYLE+ either manual or auto
* +CONFIGURE_PROG+ overwrite default configure programm
* +MAKE_FILE+ overwrite default Makefile
* +ALL_TARGET+ overwrite default build target
* +INSTALL_TARGET+ overwrite default install target
The variables to add or overwrite preprocessor, compiler and linker flags:
* +TARGET_CPPFLAGS+ flags for the preprocessor
* +TARGET_CFLAGS+ flags for the compiler
* +TARGET_LDFLAGS+ flags for the linker
* +TARGET_CXXFLAGS+ flags for the C++ compiler
* +HOST_CPPFLAGS+ flags used for host preprocessing
* +HOST_CFLAGS+ flags used for host compiling
* +HOST_LDFLAGS+ flags used for host linking
* +HOST_CXXFLAGS+ flags for the C++ host compiler
