There is Proc.cpp:
How do I suppose to do it?
I think it somthing like: gcc -fPIC -l libtk8.3.a -c Proc.cpp
But it doesn't work...
Its the wrong lib. You initialize STUBS in your code, so link with the
stubs lib and define -DUSE_TCL_STUBS during compile. libtclstub8.3.a is
the lib in your case.

Is it durin the compiling or during linking?

this is what I'm doing:
ismc01 [164] gcc -fPIC -c Proc.cpp

ismc01 [165] gcc -shared -L
/nfs/iil/itools/sun4m_solaris_2.6/pkgs/tcl-tk/8.3.2/lib/ -ltclstub8.3
-o Proc.so Proc.o

every thing compiles without problems.
Then, in "wish8.3":
% load /nfs/iil/disks/home05/aagulya/TCL/Proc.so
couldn't load file "/nfs/iil/disks/home05/aagulya/TCL/Proc.so":
ld.so.1: wish8.3: fatal: relocation error: file
/nfs/iil/disks/home05/aagulya/TCL/Proc.so: symbol __gxx_personality_v0:
referenced symbol not found

No idea where this symbol comes from, sounds like gcc...

Try:
gcc -fPIC -DUSE_TCL_STUBS=1 -c Proc.cpp
gcc -shared -L /nfs/iil/itools/sun4m_solaris_2.6/pkgs/tcl-tk/8.3.2/lib/
-ltclstub8.3 -o Proc.so Proc.o

another thing:
the command: gcc -shared -L
/nfs/iil/itools/sun4m_solaris_2.6/pkgs/tcl-tk/8.3.2/lib/ -ltclstub8.3
-o Proc.so Proc.o
taking into acount only the dynamic library (libtclstub8.3.so), isn't
it?
There is no dynamic lib libtclstub8.3.so, only a static libtclstub8.3.a,
STUBS allows you to load your extension into Tcl 8.5/Tcl 8.4 without a
recompile, which would otherwise be needed. Additionally it allows you
to use your extension in wrapped form (for example in starkits).

what I need is static...
What do you need static (and why?) If you need a fully static tclsh with
some extra functionalities you are on the wrong track. Static packages
work differently, see the tclkit or dqkit builds for some nice single
file shells with extra static packages included.

And to repeat myself: Tcl 8.3.2 is ancient, get something more recent.
