Re^2: perl v5.28.1 install GPIB module fail

in thread perl v5.28.1 install GPIB module fail

Hi Rob, thanks for your reply. please take a look at the below log. one more piece of information: I have tried the older ActivePerl version, and the installation succeeded. (I just want to update to the new Perl version for other module installation.) I will try strawberry Perl later, maybe I should switch to a Linux environment. also, copy the README of this GPIB module

Windows NT Source Installation
------------------------------

This might work on WIN98 as well, but I haven't tested it.

Install your GPIB card if you want to access devices directly 
from the NT machine.  Make sure the GPIB card is working and 
the Microsoft C libraries are installed.

Make sure your Perl is at least 5.005.  Get the latest from
http://www.activestate.com.

Make sure you have the following CPAN modules, the installation proces
+s
will complain with helpful messages if you don't have these modules.
    MD5
    Storable

Edit Makefile.PL to exclude any modules that don't interest you.  Modu
+les
that don't yet function under NT (GPIB::hpserial, GPIB::llp) are
automatically excluded.

Edit ni/Makefile.PL if you are using a National Instruments GPIB card
and make sure the paths to the include files and libraries are correct
+.

    tar zxvf gpib-xxx.tgz

    -- Edit Makefile.PL, ni/Makefile.PL 

    perl Makefile.PL
    nmake

    -- Create C:\PGPIB.CONF

The excerpt you posted above confirms syphilis's hunch about checking `perl -V:cc`. It is empty as you discovered. The `make` output shows that it is likely trying to execute a `$(CC) -c ...` but `CC`, which most likely is set via `perl -V:cc`, is empty. And tries to execute `-c` which follows. Perlmonks have answered a similar question here: https://stackoverflow.com/questions/65728942/how-to-make-perl-makefile-pl-use-a-given-c-compiler-when-compiling-an-xs-module and offer solutions by either telling `perl Makefile.PL` what `CC` to use (`perl Makefile.PL CC=...`) or how to save your CC choice permanently with Perl's config. If all else fails, a quick hack would be to edit the `Makefile` produced (not the `Makefile.PL`) and find where `CC` is set, perhaps a `CC=` line near the top. And set it to the path of the compiler executable which compiled `perl.exe` (do you have one?). Having said that, you will likely encounter additional errors with the linker (`perl -V:ld`). Usually, and in my system, linker executable can be replaced by the compiler, so additionally set `LD` (in `Makefile`) to the same CC executable. bw, bliako	[reply] [d/l] [select]

cc='undef'; I will bet you all of the money in all of the world (except for that miniscule portion that actually belongs to me) that your "older ActivePerl version" that successfully built the module in the past did not respond to `perl -V:cc` with output of `cc=undef;`. I would not even consider trying to build a perl extension on a perl that reported `cc='undef';` The fact that it built on an older ActivePerl gives me hope that the same can be achieved with Strawberry Perl. And that's where I would recommend starting. Recent ActivePerl offerings (and your 5.28.1 might be one of these) provide an opportunity for you to request ActiveState to build the module for you You could perhaps try that. I don't know how that all works ... if it works at all ... it's just something I've read about ... and I'm not at all interested in it. But it's another option for you to investigate, if you're interested. Personally, I'd start with Strawberry Perl. Cheers, Rob	[reply] [d/l] [select]
