    I'm having a compile problem with 3.38-beta1 on Linux Redhat 8.
Does anyone know of a reasonable workaround? What I'm seeing follows:

% uname -a
Linux clamato.umdl.umich.edu 2.4.18-27.8.0smp #1 SMP Fri Mar 14 05:47:33 EST
2003 i686 i686 i386 GNU
/Linux

% gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2/specs
Configured with:
../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info
 --enable-shared --enable-threads=posix --disable-checking --host=i386-redha
t-linux --with-system-zlib --enable-__cxa_atexit
Thread model: posix
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)


I get the same compile error whether I run ./configure or
./configure --enable-dwarf or simply ./configure

The error:

<snip>

cd ups && make   ups
/usr/local/src/ups-3.38-beta1/ups
make[1]: Entering directory `/usr/local/src/ups-3.38-beta1/ups'
gcc -Wmissing-prototypes -Wunused -c -pipe -O2  -DHAVE_CONFIG_H  -I.  -I/usr
/X11R6/include -Idevelhdrs   ./ao_elfcore.c
ao_elfcore.c: In function `get_note_info':
ao_elfcore.c:256: duplicate case value
ao_elfcore.c:232: previously used here
make[1]: *** [ao_elfcore.o] Error 1
make[1]: Leaving directory `/usr/local/src/ups-3.38-beta1/ups'
make: *** [ups] Error 2

The 2 case labels causing the problem in question are;

  case NT_TASKSTRUCT:
and
  case NT_PRXREG:

After cpp they are both "4" which I believe means the #defines in my
/usr/include/elf.h are in play:

/* Legal values for note segment descriptor types for core files. */

#define NT_PRSTATUS 1  /* Contains copy of prstatus struct */
#define NT_FPREGSET 2  /* Contains copy of fpregset struct */
#define NT_PRPSINFO 3  /* Contains copy of prpsinfo struct */
--> #define NT_PRXREG 4  /* Contains copy of prxregset struct */
--> #define NT_TASKSTRUCT 4  /* Contains copy of task structure */
#define NT_PLATFORM 5  /* String from sysinfo(SI_PLATFORM) */
#define NT_AUXV  6  /* Contains copy of auxv array */
#define NT_GWINDOWS 7  /* Contains copy of gwindows struct */
#define NT_ASRS  8  /* Contains copy of asrset struct */
#define NT_PSTATUS 10  /* Contains copy of pstatus struct */
#define NT_PSINFO 13  /* Contains copy of psinfo struct */
#define NT_PRCRED 14  /* Contains copy of prcred struct */
#define NT_UTSNAME 15  /* Contains copy of utsname struct */
#define NT_LWPSTATUS 16  /* Contains copy of lwpstatus struct */
#define NT_LWPSINFO 17  /* Contains copy of lwpinfo struct */
#define NT_PRFPXREG 20  /* Contains copy of fprxregset struct*/

I do also note that on my system /usr/include/linux/elf.h has just:

#define NT_PRSTATUS     1
#define NT_PRFPREG      2
#define NT_PRPSINFO     3
#define NT_TASKSTRUCT   4
#define NT_PRFPXREG     20


Many Thanks,

Phil.
