sopc Generation Error

[Altera_Forum]

Hi I am trying to generate the SOPC example design provided with Nios II EDS. (Standard.qpf) and I am getting the following error. Any one know how to fix this? Is it anything to do with setting the path? 

 Info: Starting PTF file elaboration.  3 [main] sh 1428 fork: child 3920 - died waiting for longjmp before initialization, errno 11 c:/altera/72/quartus/sopc_builder/bin/nios_sh: fork: Resource temporarily unavailable   Error: C:\altera\72\nios2eds\examples\verilog\niosII_cycloneII_2c35\low_cost/NiosII_cycloneII_2c35_low_cost_sopc.ptf: Failed to refresh PTF file

Hi ganenn! 

 I get the same error while trying to generate the DE_NET example system. Have you found a way to get your system working?  Thanks for any clues, Macbeth

Change the permission on directory. I think when you copy those folders they stay with the read only permission.

Thanks for your answer, the directory really was in read-only. However, the real problem was my Windows Vista which by default is not compatible with the cygwin1.dll of the SOPC system. So I had to replace the cygwin1.dll in altera\72\quartus\bin\cygwin\bin with a new one from a recent cygwin-installation. Now the generation works just fine.

Thanks! Replacing cygwin1.dll worked for me also!!!
