configuration problem with DDD 3.3 ?

[John Bartelt]

Hello.  I am trying to build ddd verion 3.3 on a solaris 2.6 machine.
I have run into the following problem with configure script:

....
checking for Motif... libraries in default path, headers in default path
checking for Athena... libraries in default path, headers in default path
checking for Xpm... libraries /usr/local/lib/X11R5, headers 
/usr/local/X11R5/include
checking for XOpenDisplay in -lX11... no
configure: error: The X11 library '-lX11' could not be found.
                  Please use the configure options '--x-includes=DIR'
                  and '--x-libraries=DIR' to specify the X location.
                  See the files 'config.log' and 'ddd/config.log'
                  for further diagnostics.
configure: error: ./configure failed for ddd

The ddd/config.log ends with this:

#include <X11/Intrinsic.h>
#include <X11/xpm.h>

int main() {
XtToolkitInitialize();
; return 0; }
configure:7836: checking for XOpenDisplay in -lX11
configure:7858: g++ -o conftest -g -O2    -isystem /usr/local/X11R5/include 
-isystem /afs/slac/package/X11/R6.4/sun4x_56/include  -L/usr/local/lib/X11R5 
-R/usr/local/lib/X11R5  -L/afs/slac/package/X11/R6.4/sun4x_56/lib 
-R/afs/slac/package/X11/R6.4/sun4x_56/lib conftest.C -lX11  -lSM -lICE -lsocket 
 
-lnsl  -lSM -lICE -lsocket  -lnsl 1>&5
ld: fatal: file /usr/local/lib/X11R5/libX11.a: unknown type, unable to process 
using elf(3E) libraries
ld: fatal: File processing errors. No output written to conftest
collect2: ld returned 1 exit status
configure: failed program was:
#line 7844 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error.  */
#ifdef __cplusplus
extern "C"
#endif
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char XOpenDisplay();

int main() {
XOpenDisplay()
; return 0; }


The command I used in this case was:

$ ./configure --prefix=/afs/slac/package/gnu2/ddd/3.3 
--exec-prefix=/afs/slac/package/gnu2/ddd/3.3/sun4x_56 
--x-includes=/afs/slac/package/X11/R6.4/sun4x_56/include 
--x-libraries=/afs/slac/package/X11/R6.4/sun4x_56/lib

Initially, I did not specify the X11 lib or include dir.  I then tried
several different versions of X11.  All came up with same error.  Note that
that configure is using the dirs I specified, but they are later in the
list than the X11 dirs it found.  I can find nothing wrong with the
the file it complains about:

$ file /usr/local/lib/X11R5/libX11.a
/usr/local/lib/X11R5/libX11.a:  current ar archive, not a dynamic executable or 
shared object

(I realize this is an old version, but as you see, attempts to override
this selection fail.)

Is this a bug in the configure script?  Can you suggest a solution or
work-around?

Thanks, John Bartelt
