Sys::MemInfo on AIX

rgren925 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks.

I'm installing Sys::MemInfo from cpan and it has installed fine on linux, solaris and hp-ux. It's failing on aix (both 5.3 and 6.1) with the following:

I'm guessing that there is some c library that is missing that contains 'u_longlong_t; but I really don't know that stuff very well. Any ideas what I need to do to get this module to install?

Thanks very much, Rick

In this line from the make log: `/opt/tools/nagios/perl/bin/perl /opt/tools/nagios/perl/lib/5.2 +0.1/ExtUtils/xsubpp -noprototypes -typemap /opt/tools/nagiosc` [download] the `-typemap` param of `xsubpp` specifies a file which contains data-type mappings between C and XS (see xsubpp). My default typemap file (in `/usr/share/perl5/ExtUtils/typemap`) starts with these: `# basic C types int T_IV unsigned T_UV unsigned int T_UV long T_IV unsigned long T_UV ...` [download] The above command line specifies the typemap file to be `/opt/tools/nagiosc`. If this is indeed a file and a typemap file then you could try adding a line like this: `u_longlong_t T_UV` [download] or, if indeed `T_ULONGLONG` exists in Perl,: `u_longlong_t T_ULONGLONG` [download] The type `u_longlong_t` most likely refers to C's `unsigned long long` (a long is 4 bytes, this must be 8 but that's probably system dependent). And must be known to AIX as it is mentioned in `libperfstat.h` which contains the function signature for `perfstat_memory_total()` used by `arch/aix.xs` in Sys::MemInfo. The XS files for other systems in Sys::Meminfo, e.g. `linux.xs` etc. use a `double` for the return type of the meminfo functions e.g. `arch/linux.xs`. The quick hack would be to replace `u_longlong_t` with `double` in file `arch/aix.xs` So, either get a typemap file which contains said datatype mapping (googling got me one for CORBA::omniORB at https://metacpan.org/source/HOUSEL/CORBA-omniORB-0.9/typemap) or replace mapping with a `double` like the other os's do and see if that works. bw, bliako	[reply] [d/l] [select]

It worked! The change from u_longlong_t to double actually needed to be made in MemInfo.xs. All the platforms are now working. Thank you so much for this! Rick	[reply]

Cool! just test it so that you make sure you don't loose out on the conversion. Maybe the following C program will tell you the type sizes provided you manage to compile it: `#include <stdio.h> #include <libperfstat.h> int main(void){ printf("double: %d bytes\n", sizeof(double)); printf("u_longlong_t: %d bytes\n", sizeof(u_longlong_t)); printf("unsigned long long: %d bytes\n", sizeof(unsigned long +long)); return(0); }` [download] Note: others here who do know the internals of Perl may have a better solution, if your application is critical. bw, bliako	[reply] [d/l]

I'm not sure at all that this is related, but which versions of Perl do you have on your Linux, Solaris, HP-UX, and AIX environments? I'm asking because I used to be stuck with very old versions of Perl (5.8) on some AIX environments we were using (but I can't remember which version of AIX it was, our last old AIX environments have been migrated to Linux about a year ago).

Re^2: Sys::MemInfo on AIX by rgren925 (Beadle) on Sep 04, 2018 at 18:52 UTC
It's 5.20.1 on all platforms	[reply]
Re^3: Sys::MemInfo on AIX by Laurent_R (Canon) on Sep 04, 2018 at 21:20 UTC
OK, thanks, then it's not related to the Perl version. I was just trying to shoot in the dark.	[reply]
