To be consistent with the recent change of FOO_MAKE_OPT into FOO_MAKE_OPTS, make the same change for FOO_BUILD_OPT.

|
|
==== +luarocks-package+ tutorial
|
|
|
|
First, let's see how to write a +.mk+ file for a LuaRocks-based package,
|
|
with an example :
|
|
|
|
------------------------
|
|
01: ################################################################################
|

02: #

03: # luafoo
|
|
04: #

05: ################################################################################
|

|
07: LUAFOO_VERSION = 1.0.2-1
|
|
08: LUAFOO_DEPENDENCIES = foo
|
|
09:
|
|
10: LUAFOO_BUILD_OPTS += FOO_INCDIR=$(STAGING_DIR)/usr/include
|
|
11: LUAFOO_BUILD_OPTS += FOO_LIBDIR=$(STAGING_DIR)/usr/lib
|
|
12: LUAFOO_LICENSE = luaFoo license
|
|
13: LUAFOO_LICENSE_FILES = COPYING
|
|
14:
|
|
15: $(eval $(luarocks-package))
|
|
------------------------
|
|
|
|
On line 7, we declare the version of the package (the same as in the rockspec,
|
|
which is the concatenation of the upstream version and the rockspec revision,
|
|
separated by a hyphen '-').
|
|
|
|
On line 8, we declare our dependencies against native libraries, so that they
|
|
are built before the build process of our package starts.
|
|
|
|
On lines 10-11, we tell Buildroot to pass custom options to LuaRocks when it is
|
|
building the package.
|
|
|
|
On lines 12-13, we specify the licensing terms for the package.
|
|
|
|
Finally, on line 15, we invoke the +luarocks-package+
|
|
macro that generates all the Makefile rules that actually allows the
|
|
package to be built.
|
|
|
|
[[luarocks-package-reference]]
|
|
|
|
==== +luarocks-package+ reference
|
|
|
|
LuaRocks is a deployment and management system for Lua modules, and supports
|
|
various +build.type+: +builtin+, +make+ and +cmake+. In the context of
|
|
Buildroot, the +luarocks-package+ infrastructure only supports the +builtin+
|
|
mode. LuaRocks packages that use the +make+ or +cmake+ build mechanisms
|
|
should instead be packaged using the +generic-package+ and +cmake-package+
|
|
infrastructures in Buildroot, respectively.
|
|
|
|
The main macro of the LuaRocks package infrastructure is +luarocks-package+:
|
|
like +generic-package+ it works by defining a number of variables providing
|
|
metadata information about the package, and then calling +luarocks-package+. It
|
|
is worth mentioning that building LuaRocks packages for the host is not
|
|
supported, so the macro +host-luarocks-package+ is not implemented.
|
|
|
|
Just like the generic infrastructure, the LuaRocks infrastructure works
|
|
by defining a number of variables before calling the +luarocks-package+
|
|
macro.
|
|
|
|
First, all the package metadata information variables that exist in
|
|
the generic infrastructure also exist in the LuaRocks infrastructure:
|
|
+LUAFOO_VERSION+, +LUAFOO_SOURCE+, +LUAFOO_SITE+,
|
|
+LUAFOO_DEPENDENCIES+, +LUAFOO_LICENSE+, +LUAFOO_LICENSE_FILES+.
|
|
|
|
Two of them are populated by the LuaRocks infrastructure (for the
|
|
+download+ step). If your package is not hosted on the LuaRocks mirror
|
|
+$(BR2_LUAROCKS_MIRROR)+, you can override them:
|
|
|
|
* +LUAFOO_SITE+, which defaults to +$(BR2_LUAROCKS_MIRROR)+
|
|
|
|
* +LUAFOO_SOURCE+, which defaults to +luafoo-$(LUAFOO_VERSION).src.rock+
|
|
|
|
A few additional variables, specific to the LuaRocks infrastructure, are
|
|
also defined. They can be overridden in specific cases.
|
|
|
|
* +LUAFOO_ROCKSPEC+, which defaults to +luafoo-$(LUAFOO_VERSION).rockspec+
|
|
|
|
* +LUAFOO_SUBDIR+, which defaults to
|
|
+luafoo-$(LUAFOO_VERSION_WITHOUT_ROCKSPEC_REVISION)+
|
|
|
|
* +LUAFOO_BUILD_OPTS+ contains additional build options for the
|
|
+luarocks build+ call.
