[eclipse-clp-users] questions on building eclipse 6.0_183 on OpenSolaris

Hello,

I am trying to build Eclipse 6.0_183 on OpenSolaris, using 
gcc 4.3.3.  The platform selected by configure is 
i386_sunos5 (despite the fact that the machine is a dual 
core AMD 64).  I have two major questions:

1. The build insists that "the Java interface not supported":

...

For the graphical user interface TkECLiPSe you need Tcl/Tk 
(8.5 8.4 8.3).
We will use the following Tcl/Tk installation:
   TCL_VERSION:      8.4
   TCL_WISH:         /usr/bin/wish8.4
   TCL_ARCH_LIBRARY: /usr/lib
   TCL_LIBRARY:      /usr/lib/tcl8.4
   TK_LIBRARY:       /usr/lib/tk8.4

Accept (a), find automatically (f), specify manually (m), or 
skip (s) [a]?
Hit return to accept, or enter new value:
----------------------------------------------------------------------
Java interface not supported in this configuration, skipping.
----------------------------------------------------------------------
You didn't unpack the ECLiPSe reference documentation.
----------------------------------------------------------------------
You have requested the default configuration of eclipse.
----------------------------------------------------------------------
Making 
/export/home/ko/build/Eclipse_6.0_183/bin/i386_sunos5/eclipse
Making 
/export/home/ko/build/Eclipse_6.0_183/bin/i386_sunos5/tkeclipse

...

Nevertheless, later on it says

======== make_javainterface ========
gmake[1]: Entering directory 
`/export/home/ko/build/Eclipse_6.0_183/JavaInterface'
mkdir -p ./classes


What is going on?


2. Since --prefix= is not supported by configure, I tried to 
install in /opt/eclipse/6.0 using RUNME.  However, this only 
created

eclipse* jeclipse*  lib/  man/  tkeclipse*  tktools*

not even a bin/. tkeclipse seems to work, but jeclipse comes 
up in text mode.  I expected that to be a GUI of some sort. 
Also, the jeclipse script still refers to my "build" directory

ECLIPSEDIR="${ECLIPSEDIR:-/export/home/ko/build/Eclipse_6.0_183}"

even though it's installed in /opt/eclipse/6.0.


3. And a final question: is there any reason that the (free) 
Sun Studio 12 compilers can't be used instead of gcc to 
build Eclipse?  (I have a 64-bit Symphony installation 
compiled with Sun Studio that is not usable by gcc because 
of C++ name-mangling issues.)

Thanks very much.
