Re: (4): Running a C Program within Perl.

Can you run the command at the prompt?

What kind of error are you getting exactly?

Show us a code snippet.

Update: I saw your reply at Re: Re: Running a C Program within Perl.. What command are you trying to run (are your getting a "no such file or Directory" type error and then trying to treat that as valid output)?

Cannot offer more help without more information: what platform are you running on? what is the expected output of your C program? what does your perl program do with that output; etc. ???

Or, you can teach him to fish and feed him for a lifetime

I can run this at the prompt, but putting in the following, /opt/BIPSConnect/bin/rdes, but when I put it in perl code (here is what I am trying to do - Quite simple and nothing complex, until I get this working) ... #!/usr/bin/perl-Tw use strict; my $cmd_to_run = "/opt/BIPSConnect/bin/rdes"; my @results = `$cmd_to_run`; [download] I get the following error... `/opt/BIPSConnect/bin/rdes: LD_LIBRARY_PATH=:/usr/lib:/usr/ucblib:/usr/ +openwin/lib:/usr/dt/lib:/usr/local/lib:/opt/hpnpl/lib:/p01cfg0 1/harvest/Harvest/lib:/opt/BIPSConnect/bin: is not an identifier` [download] I am most baffled and confused, please help me if you can.

Clearly, you are confused by the several parallel threads going at once ... Please see my most recent post. In short, try inserting a shebang line at the head of your `rdes` script.	[reply] [d/l]
