[Bioperl-l] [Bioperl-guts-l] Notification: incoming/1133 (fwd)

[Jason Stajich]

Apparently the newer perl releases (I used the code from 5.7.3) provides
better MakeMaker modules to handle this.
I could at least run
% make
(lots cp to blib cmds)
couldn't load shell: Argument list too long (bu22).
*** Error code 1 (bu21)
% make test

all tests ran (not necessarily passing because of DB_File problems with
the indexes)

My procedure:

Get a copy of perl 5.7.3
% cp -r perl-5.7.3/lib/ExtUtils bioperl-1.0
% cd bioperl-1.0
% perl -I. Makefile.PL
% make
[still one error reported]
% make test
(some tests still fail)
% make install
couldn't load shell: Argument list too long (bu22).
*** Error code 1 (bu21)

fails in 'make' with 'Arg list too long' message

What happens is that a list of things to MakeMake is too long for the
command line (in "# --- MakeMaker pm_to_blib section")

For the reference, command-line length limit is not
a shell limit; it is built in kernel/libc.
It has to do with the execvp()
limit ARG_MAX, which is 4096 characters in POSIX,
but most systems have it inflated, to different extents.

Test it with
--------arg_max.c--------
#include <unistd.h>
main() {
  printf("ARG_MAX = %ld\n  This is the maximum length of the arguments to the
exec() family of functions\n",
         sysconf(_SC_ARG_MAX));
  exit(0);
}
--------

Linux is the second most generous (most systems tested show 64K).
It is topped only by SUN (tried 5.8), where it is 128K.
IRIX and DEC/Alpha have 20K limit.
HP -- just 8K.

It would be prudent to stick to the POSIX limit, and
split the pm_to_blib into pieces.
