If you never build the X or FOX gates, you can delete this long
message now. 8-)
I started making some changes to our build trees a few weeks ago
to prepare for both Xorg 1.5 and for being able to build on Indiana.
One thing led to another, and before I knew it, it had turned into
my Third Annual X Open Source Makefile Overhaul (tm).
Even more astonishingly, this time I even wrote some documentation
on the results (attached to this message, will be checked into the
tree as open-src/README).
I'll be sending the changes out for code review soon (once I finish
fixing a few last build errors) and then I'll be setting up a hg repo
in the FOX project to start using them to test Xorg 1.5 pre-release
builds - so for now, this is mostly just a heads up and chance for
people to comment.
Big changes:
- Instead of some variables being APP_* in app modules, LIB_* in
lib modules, and other variables being LIB_* in all modules, all
modules of all types now use the same variable names. For boolean
variables, they all take "yes" or "no", not "yes" for some and "true"
for others.
- There's just one way now to specify things like running autoreconf
and man page "suntouching" flags, instead of some directories adding
makefile targets, others setting variables, etc.
- Rules that were the same or almost the same, but duplicated in
multiple makefiles are now consolidated into a common set of rules
to give us one place to make changes and the same behaviour everywhere.
- All shell scripts & Makefiles now specify use of /bin/ksh93 as the
shell instead of /bin/sh, so that build results are the same on
Nevada (where /bin/sh is the old Bourne Shell) and on Indiana
(where /bin/sh is replaced by ksh93). Some changes have been made
to them to better conform to the Shell Style guidelines from the
OpenSolaris Shell project (mostly ones that improve performance or
readability).
- Specifying the compiler for a module to be Sun Studio or gcc is
easier and cleaner, and changing the default to gcc should also
be easier if someone was to be porting OpenSolaris X to a new platform.
- Now that most components are migrated to open-src, and there are
no dependencies on xc bits anymore, the "BEFOREX" and "AFTERX"
lists to build part before the closed source xc gate, and part of
it after are gone - there's just one list to build, and it's all
built before the xc gate, which should also help us make sure the
open builds are buildable without xc.
New features:
- A "xmake" script is provided that will let you run builds in
subdirectories with all the flags normally provided when run
from the module directory - i.e. you don't have to just run
make in open-src/xserver/xorg - you can run xmake in
open-src/xserver/xorg/build_32/hw/xfree86/util/xorgcfg if that's
all you want to rebuild.
- A "find-build-errors" script is included that picks out the
errors from the buildit and make_release packages logs and
just prints those to make it easier to find the 10 lines of
errors in the 16 megs of log files from a full build.
- The version of a upstream source can be set to "git" to cause
it to be checked out of git instead of using a tarball - this
won't be allowed in code checked into the master gate, but will
be useful for developers tracking upstream changes, such as in
the afore-mentioned Xorg 1.5 pre-release porting gate I'll be
setting up.
- "make configure" will just run the configure script or equivalent
(split out of the build step of the previous rules)
- "make debug" and "make debug-install" will build and install
binaries built with debug flags (-g) instead of optimization flags
and as a random bonus, I've migrated our mdb modules/scripts package
from the closed source portion of the tree to open-src/utils, which
includes the mdb modules to walk the clients and grabs lists in the
X server and scripts to run these to list all current clients and
current device/server grabs, and modified them to add Xorg support
to the existing Xsun code. These aren't shipped in Solaris or
OpenSolaris, just provided as a tool for developers to debug with.
Plus, if you order now, this bonus knife will be yours for only...
wait, wrong script, never mind.
