rakudo-star-2015.03, Fedora 21 x86_64
It is possible to build and run MoarVM on systems that prohibit
executable stacks? I have executable stacks and executable heaps turned
off for security reasons on my web servers. Here's what happens when I
try to build Rakudo Star:
$ perl Configure.pl --backend=moar --gen-moar
[... lots of output ...]
Building NQP ...
/usr/bin/perl Configure.pl
--prefix=/home/markmont/rakudo/rakudo-star-2015.03/install
--backends=moar --make-install
/home/markmont/rakudo/rakudo-star-2015.03/install/bin/moar: error while
loading shared libraries: libmoar.so: cannot enable executable stack as
shared object requires: Permission denied
===SORRY!===
No suitable MoarVM (moar executable) found using the --prefix
(You can get a MoarVM built automatically with --gen-moar.)
Command failed (status 32512): /usr/bin/perl Configure.pl
--prefix=/home/markmont/rakudo/rakudo-star-2015.03/install
--backends=moar --make-install
$
Hacking MoarVM/Configure.pl to turn off JIT doesn't help, the same
problem still occurs. However, everything works fine if I undo the
lockdown to permit executable heaps/stacks, relocatable text segments,
and unconfined users.
Parrot formerly worked fine on these systems.
Is there any way to use MoarVM without needing executable stacks or
executable heaps, so that it functions purely as a bytecode interpreter?
