Yes, that confirms that the E2BIG for execve() is caused
by too large args+env passed to the program.
According to IBM docs, AIX 5 has a ridiculous, non-configurable
limit of 24K for args.
The main culprit here is PAR::Packer: it calls par with one
argument that is already 23K long (it's a "perl -e ..." type
command). Maybe I can eliminate that, but that's a bit of work
and I want to make sure beforehand that this the only reason
why PAR::Packer doesn't work on AIX 5.
Hence, are you ready for a little experiment?
(1) Run "make clean" to start with a clean slate
(2) Try to shrink your process enviroment by unsetting all
environment variables that are not absolutely necessary
(3) Strip non-functional whitespace from script/par.pl
(saves ~4K) by running
$ perl -i -p -e 's/^\s+// if /^=cut/../^1;/' script/par.pl
(4) Save some more environmental bytes by reducing the array
ld_path_keys in function par_setup_libpath in myldr/mktmpdir.c
like this
const char *ld_path_keys[3] = {
"LIBPATH", "PATH", ""
};
(note the empty string as last element)
(5) Now try a normal build
$ perl Makefile.PL
$ make
$ make test
Cheers, Roderich
