Thanks for the advice!

I have indeed installed the TclTkAquaBI and tried but it'svery
complicated.
I don't know whether you can help ?

1) I need to build my own wish with shared objects (libtcl.dylib
etc...) which
are not provided in TclTkAquaBI distribution - even using it together
with the native Tcl.framework
you don't have the *.h files etc...).
So I decided to use the Fink tcl/tk distribution which works fine.

2) Using the TclTkAquaBI (the one which includes xotcl-1.2) is also not
easy when you
want to link an xotcl shared object (called
/Library/Tcl/xotcl1.2/libxotcl1.2.dylib)
First, because you need xotcl.h, so you have to download separately the
sources
that have been used for building the shared library (sources are kindly
distributed
from http://tcltkaqua.sourceforge.net/8.4.7.html). Even using
libxotcl.dylib file distributed in TclAquaBI not not make sense for a
simple reason: if I need another package (such as BLT), which is not
distributed in TclAquaBI, I will also
have to compile it myself, which is very difficult when it is not
configured for this purpose (blt is also distributed in Fink).

3) So, sy conclusion was to compile Xotcl myself, which I did, I think,
successfully.
  configure;
./configure --with-tcl=/sw/lib --with-tclinclude=/sw/include
--with-tk=/sw/lib --with-tkinclude=/sw/include

  I just got errors when building xowish:

  gcc -pipe -rdynamic -o xowish tkAppInit.o \
         xotcl.o xotclError.o xotclMetaData.o xotclObjectData.o
xotclProfile.o xotclTrace.o xotclUtil.o xotclShadow.o xotclCompile.o
aolstub.o xotclStubInit.o \
         -O3 -Wall -Wconversion -Wno-implicit-int -fno-common -L/sw/lib
-ltcl8.4 \

gcc: unrecognized option `-rdynamic'
ld: Undefined symbols:
_Tk_Init
_Tk_MainEx
_Tk_SafeInit

Apparently also:
   ==> -ltk8.4 is missing ?

But xotclsh was successfully built.


4) then, I built a very simple tkAppinit.c:

#include "tk.h"
#include <xotcl.h>
int
main(argc, argv)
     int argc; /* Number of command-line arguments. */
     char **argv; /* Values of command-line arguments. */
{
     Tk_Main(argc, argv, Tcl_AppInit);
     return 0; /* Needed only to prevent compiler
warning. */
}

int
Tcl_AppInit(interp)
     Tcl_Interp *interp; /* Interpreter for application. */
{
     if (Tcl_Init(interp) == TCL_ERROR) {
         return TCL_ERROR;
     }
     if (Tk_Init(interp) == TCL_ERROR) {
         return TCL_ERROR;
     }
     Tcl_StaticPackage(interp, "Tk", Tk_Init, Tk_SafeInit);
     if (Xotcl_Init(interp) == TCL_ERROR) {
       return TCL_ERROR;
     }

     Tcl_Import(interp, Tcl_GetGlobalNamespace(interp), "xotcl::*", 1);
     if (Tcl_PkgRequire(interp, "XOTcl", XOTCLVERSION, 1) == NULL) {
       return TCL_ERROR;
     }

     return TCL_OK;
}

I got an executable (miniwish) built with the following compile/link
commands (with some warnings):

gcc -fno-common -DXOTCLVERSION=\"1.3.1\" -c -I/sw/include
-I/sw/include -I/usr/include/X11 -I/sw/include tkAppInit.c

But this executable does not work correctly:

./minibiokwish
dyld: ./minibiokwish can't open library: libxotcl1.3.1.dylib (No such
file or directory, errno = 2)
Trace/BPT trap

(executed from an X11 environment - not Aqua - of course).
