info + fix for problem compiling nam-1.0a5 using egcs v1.1

["Julio C. Navas" <navas@cs.rutgers.edu>]

Hello,

I was trying to compile the ns-allinone-2.1b3 package and I had the
following problem with compiling nam.  I fixed the problem and now nam
compiles and works.  I thought that my experience may be of help to
others......hence this email.

First, let me tell you some info. about my setup.   I have upgraded the
nam to nam-1.0a5.   My compiler is egcs v1.1 (this is important because
everything compiled fine under gcc-2.7.2).  I had the exact same problem
on Linux (RedHat 5.1 - kernel 2.0.34) and on Solaris (SunOS 5.5.1).

This is what the compiler said when I did a make in the nam directory:

$ make

rm -f main.o; c++ -o main.o -c -O2 -DTCL_TK  -DNDEBUG -DUSE_SHM
-DHAVE_LIBTCLCL1_0B5 -DHAVE_TCLCL_H -DHAVE_LIBOTCL1_0A2 -DHAVE_OTCL_H
-DHAVE_LIBTK8_0 -DHAVE_TK_H -DHAVE_LIBTCL8_0 -DHAVE_TCL_H  -I.
-I../TclCL -I../otcl -I../tkbox/include -I../tclbox/include   main.cc
In file included from main.cc:46:
paint.h:50: warning: ANSI C++ forbids declaration `PaintStaticGCSize'
with no type
paint.h:51: warning: ANSI C++ forbids declaration `PaintGCIncrement'
with no type
main.cc:221: warning: ANSI C++ forbids declaration `' with no type
main.cc:221: abstract declarator `int' used as declaration
make: *** [main.o] Error 1


in order to fix this, I did the following:

in main.cc line 221: I changed the line from:

extern "C" Blt_Init(Tcl_Interp*);

to:

extern "C" int Blt_Init(Tcl_Interp*);


in paint.h lines 50 and 51: I changed the lines from:

const PaintStaticGCSize = 512;
const PaintGCIncrement = 64;

to:

const int PaintStaticGCSize = 512;
const int PaintGCIncrement = 64;

At this point, nam compiled.......but it still complained in the
following manner ( in several places):

animation.h:54: warning: ANSI C++ forbids declaration `ClassAllID' with
no type
animation.h:55: warning: ANSI C++ forbids declaration `ClassAnimationID'
with no type
animation.h:56: warning: ANSI C++ forbids declaration `ClassPacketID'
with no type
animation.h:57: warning: ANSI C++ forbids declaration `ClassNodeID' with
no type
animation.h:58: warning: ANSI C++ forbids declaration `ClassEdgeID' with
no type
animation.h:59: warning: ANSI C++ forbids declaration `ClassQueueItemID'
with no type
animation.h:60: warning: ANSI C++ forbids declaration `ClassAgentID'
with no type
animation.h:61: warning: ANSI C++ forbids declaration `ClassLanID' with
no type
animation.h:62: warning: ANSI C++ forbids declaration `ClassTagID' with
no type
animation.h:64: warning: ANSI C++ forbids declaration
`AnimationTagIncrement' with no type


Hope this helps!

Julio
