The emulator framework handles binary-only packages that require binary
|
|
"emulation" (or ABI re-implementation) on the native operating system.
|
|
|
|
A package Makefile should set several variables in order to use the
|
|
emulator framework:
|
|
|
|
EMUL_PLATFORMS is a the list of supported <opsys>-<arch> pairs by
|
|
the package and should be set before including bsd.prefs.mk.
|
|
The emulator framework will select an appropriate supported
|
|
platform and store it in EMUL_PLATFORM.
|
|
|
|
EMUL_MODULES.<opsys> is a list of modules from <opsys> that are
|
|
required by the package.
|
|
|
|
Example use:
|
|
|
|
EMUL_PLATFORMS= linux-i386 solaris-sparc
|
|
EMUL_MODULES.linux= base compat
|
|
|
|
.include "../../mk/bsd.prefs.mk"
|
|
|
|
.if ${EMUL_PLATFORM} == "linux-i386"
|
|
DISTNAME= foobar-linux-i586.bin
|
|
...
|
|
|
|
A user may set several variables in /etc/mk.conf to influence the
|
|
choices made by the emulator framework:
|
|
|
|
EMUL_PREFER is a list of non-native platforms that should be tried,
|
|
in order, when selecting an appropriate platform.
|
|
|
|
EMUL_TYPE.<opsys> is the distribution of <opsys> that is used when
|
|
<opsys> is selected for use by the emulator framework.
|
|
|
|
"native" means that the OS is the native operating system.
|
|
"builtin" means that the OS is installed in some "compat"
|
|
location that is managed outside of pkgsrc.
|
|
|
|
For Linux, there are several additional choices for
|
|
EMUL_TYPE.linux:
|
|
|
|
"suse" means to use the highest version of SuSE in pkgsrc.
|
|
"suse-9.1" means to use SuSE 9.1 from pkgsrc.
|
|
"suse-9.x" means to use the highest version of SuSE 9.x.
|
|
"suse-10.0" means to use SuSE 10.0 from pkgsrc.
|
|
"suse-10.x" means to use the highest version of SuSE 10.x.
|
|
|
|
There are two helper targets for use by package developers:
|
|
|
|
"emul-fetch" will cause the distfiles for all platforms listed in
|
|
EMUL_PLATFORMS to be fetched.
|
|
|
|
"emul-distinfo" will generate a "jumbo" distinfo file that contains
|
|
checksums for the distfiles for all platforms listed in
|
|
EMUL_PLATFORMS.
