install.ptf missing

java problems while generating install.ptf

I get the following message when I try to rebuild

The clean removes install.ptf but the rule for creating it again can has problems

while calling &#39;sopc_builder&#39;

my $javax = "";

if ($jre_dir eq "") { $jre_dir = get_quartus_jre($quartus_dir); }

if ($jre_dir ne "") { $javax = get_java_exe($jre_dir,$shelled); }

if (! -x $javax )

{

$javax = get_java_exe($sopc_builder . "/bin/jre1.4",$shelled);

On the other hand if I open Quartus and the sopc_builder the install.ptf file

is generated correctly.

All my colleagues have the same problem. What&#39;s wrong in our installation.

We use Quartus 4.2 + Service Pack 1 and Nios 1.1.0
