Some of us are using PERL on our Windows boxes to process data, etc. Many are also using cygwin to have a UNIX-like environment. This page offers some tips on getting ActiveState's PERL to work within a cygwin environment.
First, many folks recommend using a cygwin version of Perl if you are going to use cygwin as it avoids some of the problems I have addresed below. That may be a viable solution for you. I had already invested time in building my tools based on ActiveState (which has a richer set of add-ins, like modules). The cygwin folks also recommend getting a cygwin implementation of Xemacs.
stats.pldoesn't, even though d:/parris/perl is in the path. When you try to run a script relying on the #!c:/perl/bin/perl.exe syntax to specify the program that should process the script the shell (in this case cygwin's bash) effectively executes a command like:
c:/perl/bin/perl.exe absolute_script_nameIf you are running from DOS everything is ok as this looks like:
c:/perl/bin/perl.exe d:/parris/perl/stats.plBut with cygwin it looks like:
c:/perl/bin/perl.exe /cygdrive/d/parris/perl/stats.pland Perl balks with "no such file" because it can't resolve this pathname.
#!/usr/local/bin/perland /usr/local/bin/perl looks like:
#!/bin/sh # This is necessary to make perl work with cygwin. Cygwin passes # "cygwin style" paths to the program in the #! statement and ActiveState # perl does not know what /cygwin/d/... means. # So, we put #!/usr/local/bin/perl in the perl script and this is called # This routine translates the path name to something of type d:/ args="" while [ $# -gt 0 ] do var=$1 shift if test "`echo $var | grep '/'`" = "$var" then # cygpath does the /cygwin/d/ to d:/ conversion var=`cygpath -w $var` # but then we have to swap \ for / (extra \ needed because the # shell makes a first pass at removing the \. var=`echo "$var" | sed 's/\\\/\\//g'` fi args="$args $var" done # finally the command is to call perl with the name of the script and the args. cmd="c:/perl/bin/perl.exe $args" $cmd
This uses the cygwin command, cygpath to convert to a windows style pathname and then convers \ to / before calling perl. This script could certainly be a lot more robust but it gets the job done for me.
