Compile perl 5.6.1 on hpux 11.0 - make test fails

[Raymond Cordoni]

I am compiling perl 5.6.1 on hpux 11.0 using the HP ANSI C compiler and PA-RISC2.0 architecture and my make test fails in two places - op/grent and op/pwent. These tests generate a core dump on my system. A forum search comes up with a couple of people having the same problem - but no solution. Perl 5.6.0 did not have this problem. Does anybody know of a solution?

I also did a google group seach and found more information about this problem, but again no solution. Thanks to Jim Garner for the following:

If you succeed in compiling on HP-UX 11.0, let me know your experience with the
following: I've had a problem with the perl-5.6.1 getpwent() function when
compiled under HP-UX 11.0 -- it dumps core if I call it at eof. The pwent()
test that comes with perl calls the function a fixed number of times (25), so
if your /etc/passwd is 25 or more entries, the test appears to pass. I can
write a C program to call getpwent() past eof and it returns properly, so the
problem is not with the HP library call. I'd like confirmation of this problem
before reporting it as a bug.

Have you tried to load a precompiled version? Try this:

I am not able to use the binary distribution for perl because it does not work with the DBD-Oracle module. In order to install DBD-Oracle, you have to compile perl with additional linker flags -lpthread -lcl.

Ray,

You might try using 'gcc' to compile perl 5.6.1 on your 11.0 machine. I've had success in compiling perl from the source using gcc instead of the default HP C compiler. You can find a binary distribution here:

http://hpux.connect.org.uk/hppd/hpux/Gnu/gcc-2.95.3/

Be sure to download binutils as well and have both of these in your PATH when compiling perl 5.6.1. Hope that helps.

I believe that you will also need the gmake utility from GNU also.

Mike,

the default C compiler is only for the kernel. It shouldn't be used for programming (or building anything).

I've used gcc and gmake with 5.6.0 it works fine.

I have an Admin here who built 5.6.0 on 11.0 with HP C/ANSIC. He had to tweak something in the ./Configure script to make it work. I'm sure that 5.6.1 isn't much different from that perspective. I'll ask him in the morning (9am PST). Email me if I haven't posted anything shortly thereafter.

Mike,

I meant to say that if HP C/ANSIC isn't available, something else like gcc must be used since the default compiler is for the kernel.

After reading my earlier response, it kinda came out pretty sukky. Sorry 'bout that.

Thanks for all the input. I have the HP Ansi C compiler so I don't need gcc and I am not trying to use the braindead kernel compiler. I suspect that there is a bug in the pwent() and grent() routines in perl 5.6.1 that wasn't there in 5.6.0. I don't really need (as of this writing) either of these routines - I just wanted a clean "make test". I have since installed all the perl modules I use and done some basic testing and all looks OK.

You may be able to get around this by having the libraries (-lpthread -lcl) first and then the default libraries. This works on our N class running HP-UX 11.00. You can set the order of the libraries when running the configure program. When asked for libraries use -lpthread -lcl $*. This solution is bothersome since the order of the libraries should not make any difference. Possibly a word boundary problem.

I did try -lpthread -lcl at the beginning and it made no difference. Interestingly enough, putting it in reverse order "-lcl -lpthread" makes the DBD-Oracle install fail - so order is important!

Ray,

What I've found is that the pwent.t and grent.t tests read $max entries from the /etc/passwd and /etc/group files. If there are less than $max enties that test fails. To get it to pass count the number of entries in both files:
cat /etc/passwd | wc -l
cat /etc/group | wc -l
Next edit pwent.t and modify $max to equal the number of entries in the passwd file. The $max variable is around line 64.
Do the same with grent.t using the number of lines in the group file.
Good Luck,
Steve
