Hi,
I am trying to startup a squeak image from another squeak image. I have the following command. p := PipeableOSProcess forkAndExec:'Squeak.exe' arguments: #('Squeak3.10.2-7179-basic.image') environment: nil descriptors: nil workingDir: 'C:\Documents and Settings\Arushi Aggarwal\Desktop\CS598\win32-Squeak3.10.2-7179\Squeak3.10.2-7179\' errorPipelineStream:(InternalPipe nonBlockingPipe nextPutAll: 'this is the error stream '; yourself). It does not seem to recognize the argument that is being passed, and prompts for the user to choose the image. Both Squeak.exe and the image lie in the path that has been specified as the workingDir. Is there anything else I can do to make it recognize the argument? Thanks Arushi |

Hi Arushi, OSProcess support for Windows is not as complete as it should be, so some of the things that work on Linux do not work properly on Windows. It looks like you have successfully built an OSProcessPlugin for your Windows system (well done!). I do not have a Windows system with me today and I have not looked at this in a while, but I am afraid that passing command line arguments may be one of the things that is not complete on Windows. Another thing that could be an issue is that the OS pipe support on Windows does not work, so on Windows you cannot read and write the input and output streams to the external Squeak process that you are starting. I don't know it that is a concern for you or not. Dave |
Hi,
Thanks for the reply. I managed to get it to work with arguments, that dont have spaces in the path. Works for now. Arushi On Sat, Apr 24, 2010 at 7:35 AM, David T.
