Re: gracebat runs in X, but not as a system call from a perl script

Forgot to say that the error message is :the system cannot

I do startxwin to open X and then do
gracebat <parameters>
this does what I want, namely produce a jpeg file

Now if I try this for a perl script(run from X)
system(gracebat <parameters>)

i.e. the exact same line that produced the right result
I get an error.

I guess the reason is that I am using the activestate perl instead of the
cygwin
perl; anyway there were reasons for that, not sure if valid or not[the
reason
was getting DBD::Oracle to work, which was a huge pain].
So I guess "system" to perl is whatever system Activestate was installed
for,
i.e. Windows.
The question is:
Is it possible to get around this?
Can I tweak the system command so that it executes gracebat(but
otherwise use Activestate, e.g. for Oracle DBI queries?
If you use Activestate then I believe it invokes cmd.exe for your system call. Take the parameter you passed to system in your Activestate perl and plug it into a cmd.exe shell (copy and paste). Massage until it works under cmd and copy and paste that new command back into your perl and it should work.

My guesses would be that you are using "C:/path/to/gracebat <parms>" and Activestate invoking cmd can't find that or perhaps you are literally using "gracebat <parms>" and gracebat is in Cygwin's PATH but not cmd's PATH.

If work is so terrific, why do they have to pay you to do it?
