I am trying to write a simple perl script to compile my java code but I am having some few problem. This is what I have in my perl code. The perl  file is call compile.

Code:

#!/usr/bin/perl javac  @ARGV[0] ;

I call it as below;

Compile Hello.java

My small java program does not compile. any idea?

 

Ah - I think you're a Shell programmer converting to Perl - you'll need too backquote the compile command as the way it's written, you've got it looking for as Perl function called javac.

Here's a completed (but minimal) piece of code to compile and run a Java program from Perl:

Code:

#!/usr/bin/perl print `javac $ARGV[0]`; ($basename) = ($ARGV[0] =~ /(.*)\./); print `java $basename`;

Note the need to print out the results (backquotes return the result rather than sending it to stdout).  The regular expresion match is to strip off the .java from the end of the java command so that what you run would be

jgo Hello.java

which would call up

javac Hello.java
then
java Hello

Question - have you looked at the Ant build tool - it's become pretty much a Java standard for specifiying build procedures and dependencies - a sort of OS independent version of make
