T2K needed in Linux, also?

[Kelly O'Hair]

The new sparse binary plugs will have the same exact layout as a jdk install
tree, e.g. bin, lib, jre, jre/lib, jre/bin, etc.
With one additional directory called "libfiles". This is where t2k.lib will be found,
however, look quickly, because it may be deleted from the binary plugs soon
and won't even be needed anymore. So anything you do around t2k.lib may be a bit
of a waste of time. The new sparse binary plugs are awaiting some legal issues
and should be showing up any day now.

The j2se/make/common/BinaryPlugs.gmk file has the rules for dealing with the
binary plugs and has a rule that will copy the t2k.lib file into the right
place when the make/sun/font/Makefile is run. There is an export and import
process for the BinaryPlugs. As the different engineering groups remove
the need for plugs, this file should get smaller and smaller, as will the
size of the binary plugs which will be created automatically soon.

Unfortunately we suspect there is a missing 'mkdir' in BinaryPlugs.gmk right
now:

------- BinaryPlugs.gmk -------
*** /tmp/sccs.SHa4YR    Sat Jul 28 13:57:44 2007
--- BinaryPlugs.gmk     Sat Jul 28 13:57:37 2007
***************
*** 448,453 ****
--- 448,454 ----
   import-binary-plug-t2k-library: \
       $(LIBFILES_DIR)/t2k.lib $(LIB_LOCATION)/$(PLUG_T2K_LIBRARY)
         $(RM) $(OBJDIR)/t2k.lib
+       $(MKDIR) -p $(OBJDIR)
         $(CP) $(LIBFILES_DIR)/t2k.lib $(OBJDIR)
   else # !windows
   import-binary-plug-t2k-library: \

At least that's what we think prevents the new sparse binary plug bundles
from allowing an OpenJDK build on windows to work right now.
We were testing windows builds last week just before I took off on a
short vacation.
You could simulate things by creating this "libfiles" directory and placing
your t2k.lib file in it.

As far as debugging the build process, it's not easy, but it has been
getting better over the last few releases.
Expect more build changes in the future with a goal of simplification.

Try 'gnumake -p', or there was a recent article in Dr. Dobbs about debugging
makefiles that was very helpful. Last month maybe or 2 months ago?
