ddd configure bugs (I think so!)

[Jong B. Lee]

Dear Andreas,

I can't post a mail to ddd@gnu.org.
My mail looks so strange (converted to MIME?) in the mailing list archive.
So, I write this mail to you directly.

Here, I mean the *BUG*s as configuring BUG on cygwin environment.

Wht I found is that the link order of the X libraries is NOT correct, and some 
odd things.

Your link order is :
   -lXm -lXp -lXpm -lXaw -lXmu -lXext -lXt -lSM -lICE -lX11 -lncurses -liberty 
-lm

But, this should be
   -lXm -lXp -lXaw -lXmu -lXpm -lXext -lXt -lX11 -lSM -lICE -lncurses -liberty 
-lm

According to LessTif FAQ (http://www.lesstif.org/FAQ.html#TOPIC5), the link 
order should be
-lX11 -lSM -lICE.

And, $LIBXAW $LIBXPM , NOT  $LIBXPM $LIBXAW  in Makefile.am and Makefile.in.
With the order of $LIBXPM $LIBXAW, cygwin complains some variables are 
undefined (unresolved symbols error).


Next,
<<<ddd:/configure:line # 8064>>>
echo $ac_n "checking for XawTextSetInsertionPoint in -lXaw""... $ac_c" 1>&6
echo "configure:8066: checking for XawTextSetInsertionPoint in -lXaw" >&5
ac_lib_var=`echo Xaw'_'XawTextSetInsertionPoint | sed 'y%./+-%__p_%'`
if eval "test \"`echo '$''{'ac_cv_lib_$ac_lib_var'+set}'`\" = set"; then
  echo $ac_n "(cached) $ac_c" 1>&6
else
  ac_save_LIBS="$LIBS"
LIBS="-lXaw ${XAW_LIBS} -lXpm ${XT_LIBS} ${XEXT_LIBS} ${X11_LIBS} ${X_PRE_LIBS} 
$LIBS"
cat > conftest.$ac_ext <<EOF

Here, without   -lXpm ,   -lXaw is not included.
So, I added it.


And,  sigName.C
strsignal is declared const char *, not char * in cygwin's 
/usr/include/string.h:70

So, I changed the ddd-3.2.92/ddd/sigName.C
   46c46
   < extern "C" char *strsignal(int signo);
   ---
   > extern "C" const char *strsignal(int signo);
   51c51
   <     return strsignal(signo);
   ---
   >     return (char *)strsignal(signo);



Last, ddd.C  ( mkstemp )
< template > causes parse error on cygwin c++ (I don't know why.  gcc works 
well.)
Probably because 'template' is a c++ keyword.

O.K., I changed it, too.
3077c3077
< extern "C" int mkstemp(char *template);
---
> extern "C" int mkstemp(char *templ);
