I installed it on my Windows XP machine. I want to try Perl6, but making the binary, I get this error:
C:\parrot-0.8.2\bin>pbc_to_exe.exe "C:\parrot-0.8.2\languages\perl6\perl6.pbc"
Unable to open filehandle
current instr.: '_config' pc 6 (library/config.pir:54)
called from Sub 'handle_args' pc 241 (pbc_to_exe.pir:99)
called from Sub 'main' pc 68 (pbc_to_exe.pir:29)
Am I missing something? or are there any other procedure other than this post by chromatic.
ok, I searched and found this.
Solution is to create a batch file instead as follows:
@echo off
rem adjust the path below to suit your environment
set PARROT_ROOTDIR=c:\parrot-0.8.2
%PARROT_ROOTDIR%\bin\parrot.exe %PARROT_ROOTDIR%\languages\perl6\perl6.pbc %*
I saved it as C:\parrot-0.8.2\bin\perl6.cmd
Then I added this to my PATH env variable: C:\parrot-0.8.2\bin\
Now this works:
C:\dev\perl6>perl6 hello.pl
Hello World!
Hurray, now I'm ready to play with perl6. Thanks so much!
I wrote a post about my install experience here: http://samdelacruz.blogspot.com/2008/12/want-to-try-perl6-heres-how-to-get.html
