Hi Matt.
Me too, but I think Dennis and Joerg are saying that, in theory, any
build system should be able to generate an exact duplicate of any
binary SUNW packages for which Sun has documented the build parameters
and patches used. (And assuming the original sources are available, of
course.)
To illustrate, let's suppose Solaris 10 (or Nevada) included
open-source utility "foo", shipped as binary package "SUNWfoo". (Note
I'm assuming here that the Sun consolidation team that owns "SUNWfoo" has
made available the build parameters, patches, etc. for generating it.)
- For the SPS (SchilliX's) build system:
1. Translate the build parameters (that Sun used to generate
SUNWfoo) into an SPS (aka src-get) "wrapper makefile".
2. Put copies of the patches (that Sun used to generate SUNWfoo)
into the appropriate directory.
3. Put a copy of foo.tar.bz2 (the original source from
the original site) in the appropriate directory.
4. Run (I think): src-get compile foo
5. Use pkgmk(1), prototype(4), etc. to create SUNWfoo. (I'm not sure
if this step has been automated yet.)
- For the CBE (JDS team's) build system:
1. Translate the build parameters into a CBE spec file
2. (Same as above -- copy the patches to appropriate dir.)
3. (Same as above -- copy foo.tar.bz2 to appropriate dir.)
4. Run: pkgbuild -bi SUNWfoo.spec
('pkgbuild -bi' patches, compiles, creates SUNWfoo binary
package, and installs it.)
- For the TWW build system:
1. Translate the build parameters into foo/sb-db.xml
2. (Same as above)
3. (Same as above)
4. Run sb foo/sb-db.xml
5. [ Not sure if the above creates SUNWfoo and
installs it or if another step is needed. ]
