PERL Install issue

[Scott_130]

Currently we have a version of C compiler that came with our HP Version(B.11.11) so I would imagine it is fairly up-to-date. I downloaded the newest stable release from perl and am trying to install it. The error I am getting is this:

Use which C compiler? [cc]
(Bundled) cc: warning 480: The -A option is available only with the C/ANSI C pr
oduct; ignored.
(Bundled) cc: "try.c", line 1: error 1705: Function prototypes are an ANSI feat
ure.
Uh-oh, the C compiler 'cc' doesn't seem to be working.
Configure[3773]: gcc: not found.
(Bundled) cc: warning 480: The -A option is available only with the C/ANSI C pr
oduct; ignored.
(Bundled) cc: "try.c", line 1: error 1705: Function prototypes are an ANSI feat
ure.
Uh-oh, the C compiler 'cc' doesn't seem to be working.
You need to find a working C compiler.

HOWEVER,

I know the compiler is good b/c it is being used. Also, $PATH contains the proper paths to the compiler.

Any thoughts would be greatly appreciated.

Thanks

You don't have a prayer using the bundled C compiler becausxe it only speaks K&R C and Perl is written in ANSI C. You can download and install gcc or use HP's ANSI C or aC++ compiler.

Unless you have a compelling reason to compile Perl, you can use the readily available binary ports.

If indeed you do have a configured ANSI/C compiler then /usr/bin/cc should be symbolically linked to /opt/ansic/bin/cc but the warnings you are getting indicate that the bundled c compiler is being invoked.

We have a gcc compiler installed and running but it seems to want to use the HP bundles C compiler. Can you tell me how to re-direct this in the makefile or config.sh.

Thanks

I'm doing this from memory but when you run the 'configure' script, you are prompted for a compiler. Respond with 'gcc' (you make need to use the full path).

Plan B: Edit your existing makefiles replacing cc with gcc but you will probably then have to change some compiler options as well.

[H.Merijn Brand (procura]

Plan A. Use the following command

# sh ./Configure -Dcc=gcc -des

Plan B. Use my precompiled version from https://www.beepz.com/personal/merijn or http://www.cmve.net/~merijn

Plan C. Buy the C-ANSI-C compiler. It outperforms gcc by 25%, so if you have more than only perl to compile, or you need high performance perl, it's worth thinking about.

Enjoy, have FUN! H.Merijn

[H.Merijn Brand (procura · Accepted solution]

Clay, your plan B is too complicated (and unreliable). If you want to go for plan B, start with changing config.sh (cc=gcc) before you make which will cause all the makefiles to be recreated, but again, this is dangerous, because the Configure process uses the chosen C compiler to change a lot of things. look in hints/hpux.sh to see where dragons live.

-Dcc=gcc is the way to go (you /can/ use the full path)

[Scott_130]

Thanks for the responses.

I went ahead and installed a 64-bit gcc compiler from the HP site and installed it through swinstall.

Then i re-ran the perl Configure as:

sh Configure -Dcc=gcc

And I get this error:

-----------------------------
Configure[2933]: gcc: not found. You need to find a working C compiler.
-----------------------------

Is it a problem that it is 64 bit? Also, I added the path of gcc compiler which is /usr/local/pa20_64/bin

[A. Clay Stephenson]

Well, that depends upon whether or not your platform supports 64-bit code. My first step would be to compile a very baby C program using gcc. Something as simple as

int main(void)
{
(void) printf("Hello World\n");
return(0);
}

gcc baby.c -o baby

and then see if baby executes. If so you have a working gcc.

Well I think I am making progress as I was able to get Perl installed (I used another method)

I am trying now to load modules onto the box and I got an error when loading the first (Date::Calc)

# perl -MDate::Calc -e 1
Can't load '/usr/local/lib/perl5/site_perl/5.8.0/PA-RISC2.0/auto/Date/Calc/Calc.sl' for mod
ule Date::Calc: Exec format error at /usr/local/lib/perl5/5.8.0/PA-RISC2.0/DynaLoader.pm li
ne 229.
at -e line 0
Compilation failed in require.
BEGIN failed--compilation aborted

I'm so close. Any thoughts?

The PATH to cc is probably incorrect. If you loaded the (extra cost) ANSI C compiler, it will NOT be located in /usr/bin. But since /usr/bin is early in the $PATH variable, you are getting the K&R compiler. The install process should have put /opt/ansic/bin near the front of the PATH.

First, check if you have the ANSI C compiler with swlist -l bundle If you do, there are a couple of choices:

- rename /usr/bin/cc to /usr/bin/cc-k&r and make sure that the ANSI compiler's path (in /opt/ansic/bin) is present. Check /etc/PATH to be sure that everyone sees this path.

- rename /usr/bin/cc to /usr/bin/cc and create a symlink to the ANSI compiler using ln -s /opt/ansic/bin/cc /usr/bin/cc

Perl 5 is available ready to install and run from www.software.hp.com

[H.Merijn Brand (procura]

First question: *WHY* do you need a 64bit perl??? There are still a truckload of modules on CPAN that don't work with 64bit perls (or are not threadsafe for that matter).

Unless you want to link 64bit objects later - like DBD-Oracle to 64bit ports - it is unlikely that you need 64bit perl.

FYI 64bit perl is 14% slower than 32bit perl accross the line.

Have you tried my precompiled perl from https://www.beepz.com/personal/merijn/ or http://www.cmve.net/~merijn/ ? It comes with a lot of precompiled modules.

If you still want to try yourself, be sure that the PATH to gcc is in you $PATH (either add it in /etc/PATH or add it to $PATH in your ~/.tcshrc, ~/.profile, or whatever shell initializing file you have)

[H.Merijn Brand (procura]

Are you by any chance related to "Pamela R.Schulz" ? She's just posted the same question in the perlbug database.

[Scott_130]

Well, I finaly got it.

First, the 64-bit I was referring to was the gcc compiler, not PERL. I removed the gcc compiler and installed a 32-bit version and had no problems. I just assumed that the 64 bit compiler was backwards compatible. After installing the 32-bit compiler I was able to add DBI and other modules. Thanks to everyfor there help on this issue.
