perl 5.10.0 / osx 10.5.2 'make' dies at "error: redefinition of 'union semun'"

it looks like a HAS_UNION_SEMUN or HAS_SEM needs to be undef'd?

i don't see this issue w/ 5.8.8, so it might be perl-src ...

before I blindly undef/def symbols, can anyone comment/hint on this?

Using Perl to Read jar file MANIFEST file.

[Michael Barto]

Has anybody every tried to create a Perl program ro read the contents
of the MANIFEST file in java jar file? We are trying to develop
something to provide comparisons for change between different
implementations. Is this a simple Perl backtic, system or exec of the
jar command or is there a more exotic way to do it? Also, we need to
extract Checksum. But that seems documented.

[Edward Moy]

When I build 5.10.0, I don't have this problem.  In config.h, I have:

#define HAS_UNION_SEMUN /**/

Did you run Configure and does your config.h define HAS_UNION_SEMUN?

If I remember correctly JAR files are simply Zip files so you should  
be able to use something like Archive::Zip to read the file.

if i

  ./Configure -Dfirstmakefile='GNUmakefile' ...

as usual,

 grep HAS_UNION_SEMUN config.h
  /* HAS_UNION_SEMUN:
  /*#define HAS_UNION_SEMUN / **/

after digging abt in perl src, i note that if i *ADD*

  ./Configure -Dfirstmakefile='GNUmakefile' ... -Dd_union_semun

then,

  grep HAS_UNION_SEMUN config.h
   /* HAS_UNION_SEMUN:
   #define HAS_UNION_SEMUN  /**/

and, subsequent

   make

seems happy with that.

so, the question is -- why's it need to be defined on my system, and
not on yours?

did _you_ run Configure? or the default install?

thanks.

Yes, I run Configure, and it prints:

You have union semun in .

Configure determines this by trying to compile:

--- try.c ---
#include 
#include 
#include 
int main () { union semun semun; semun.buf = 0; }
--

What happens when you try to compile the above program?

I forgot to mention that I'm still using the 4.0.1 compiler, while it  
looks like you're using the 4.2 compiler.  If the above fails to  
compile with 4.2, you might try compiling try.c with 4.0.1 just to see  
if 4.2 has a bug (though I would think this unlikely).

Well, it's a mystery.  The only other thing I can think of is if  
somehow _POSIX_C_SOURCE or _XOPEN_SOURCE are being defined when  
Configure compiles try.c (and union semun would not be defined in sys/ 
sem.h as per POSIX), but when miniperlmain.c compiles, those macros  
aren't defined, so union semun is visible in sys/sem.h, but by that  
time HAS_UNION_SEMUN has been define, so union semun gets redefined.

possibly ... checking, neither _POSIX_C_SOURCE or _XOPEN_SOURCE are
def'd in perl's config.h

either way, for now, my workaround (adding the option to config) seems
to work -- and, afaict, causes no harm.

thanks for the help.
