Re: covert perl code to binary

2019-01-11 Thread Mike Flannigan



Thanks.

My Strawberry install finally failed with
Stopping: 'install' failed for 'B::C'.

I am running ver 5.26 of Strawberry.



I suspect you mean this Readme file:

|INSTALL|
|cpan B::C|
|On strawberry I needed|
|||perl Makefile.PL FIXIN="perl -S pl2bat.bat"|
|On Windows and AIX for 5.12 and 5.14 you need to patch and rebuild CORE 
perl:|

|||ramblings/Export-store_cop_label-for-the-perl-compiler.patch|
|For 5.14 and 5.15 I recommend also the following patches:|
|||ramblings/revert-B-load-BEGIN.patch (The 5.14.1 version)|
|||ramblings/Carp-wo-B.patch|
|We generally discourage the use of perl since 5.16 unhandled and|
|unacknowledged security problems with the implementation of "unicode"|
|symbols and packagenames, where they really implemented binary names|
|for all symbols without any checks and further support of such binary|
|names. Identifiers are not identifiable anymore.|
|See the warning at perl Makefile.PL.|
|5.20 improved support for binary names for most syscalls, dumpers and|
|APIs, but TR39 and strict names are still not handled, the problems|
|are not understood and reactions are generally hostile.|
|5.18 made it 20% bigger with the implementation of COW strings.|
|Most strings cannot be stored statically anymore since then.|
|The best perl versions for the compiler are 5.14.4, 5.22.1 and cperl,|
|since these are the most tested versions, where the coretest suite 
passes. The above is only part of the Readme file. I'm not sure what to 
make of that. Especially that part that says: 'We generally discourage 
the use of perl since 5.16 unhandled and unacknowledged security 
problems' Mike |

B::C is a module that you install from CPAN.
I assume I don't put Use B::C at the top of
my perl script, but instead perlcc uses it.

Is perlcc also a module?
Or is that an executable?
I think I see that it is composed of 5 files:
assemble
cc_harness
disassemble
perlcc.PL
pl2exe.pl

After installing perlcc, do I just open a command
prompt and type perlcc -o hello.exe hello.pl?

Does all this work on Windows?  My guess is Yes.

It actually does the compilation - as opposed to pp which is just 
packaging it - so you don't see the perl code of the source file.


Does that resolve your question?

Re: covert perl code to binary

2019-01-11 Thread Mike Flannigan



Thanks.  On Windows I did 'cpan install B::C'
and it went on and on with many test fails.
After about 3 minutes it threw a 'Perl interpreter
has stopped working' error (details below) and when
I closed that box it continued with the test fails
for another 3+ minutes and then stopped (it was probably
still running - I did a Ctrl C on it).  One little
item I picked out is
ExtUtils::Install  generates non-zero binary'

So then I did 'cpan install -n B::C' and that also
ran about 5 minutes with test fails and threw a
'Perl interpreter has stopped working' error.  When
I closed that box it continued with the test fails
for another 5+ minutes (I took a shower in here) and
then slowed down on statements like


#   Failed test '6: use Pod::Perldoc -O3 gives expected 'ok' outpu
#   at t/modules.t line 227.
#   ''
# doesn't match '(?^ms:ok$)'

The install still running, but I think it is safe to say
it does not install real good on Strawberry Perl.

Opening foo, I found the string 'Hello, world.' but only once amongst

I'm afraid I don't have a Windows box to experiment with.

I could use some more explanation.

B::C is a module that you install from CPAN.
I assume I don't put Use B::C at the top of
my perl script, but instead perlcc uses it.

Is perlcc also a module?
Or is that an executable?
I think I see that it is composed of 5 files:

first of all, see

Otherwise perhaps https://metacpan.org/pod/B::C will work for you or you can
