How to tell cpan where a missing library is?

cantelow has asked for the wisdom of the Perl Monks concerning the following question:

Greetings,

On redhat-

I'm coming up unsuccessful trying to install the SAVI module with the command:

cpan SAVI

-probably because of this message when I try:

Warning (mostly harmless): No library found for -lsavi

But libsavi.so is available at /opt/sophos-av/lib/libsavi.so. Can someone point me to how to tell cpan where this is? I tried softlinks in /usr/lib and /lib pointing to /opt/sophos-av/lib/libsavi.so, but that doesn't do the trick.

Thanks tons!

From http://cpansearch.perl.org/src/PHENSON/SAVI-Perl-0.30/README: If the Sophos library is not in the default search path, edit Makefile.PL and update the -L and -R options appropriately.	[reply]

Many thanks for your monklike patience- I should have found and read the README file. The cpan command still doesn't find the library, but proceeding with fixing the Makefile and running perl Makefile.PL and make, I now come up with: `sav_if/s_comput.h:662:4: error: #error Unsupported GNU C/C++ target hardware platform` This looks to me like a sophos rather than a perl bug or inavailability, the code causing this error being: /* * Hardware platform. */ # if defined(__i386__) # define __SOPHOS_I386__ # elif (defined(__hppa__) && defined(_PA_RISC1_1)) # define __SOPHOS_HP_PA__ # elif defined(__sparc__) # define __SOPHOS_SPARC__ # elif (defined(_POWER) \|\| defined(__ppc__) \|\| defined(__POWERPC__) \|\| + defined(__PPC__)) # define __SOPHOS_POWERPC__ # elif (defined(TARGET_CPU_68K) \|\| defined(__CFM68K__) \|\| defined(m68k +) \|\| defined(_M_M68K)) # define __SOPHOS_68000__ # elif defined(__alpha__) # define __SOPHOS_ALPHA__ # elif defined (__s390__) # define __SOPHOS_S390__ # elif defined(__VAX) # define __SOPHOS_VAX__ # else # error Unsupported GNU C/C++ target hardware platform # endif [download] I don't understand this well, but I'll see what I can find out. Thanks again. Ann	[reply] [d/l] [select]

What OS are you on exactly, and what is the compiler being used?	[reply]
