Re: Pier 'How to'

Trying again from the beginning. I re-dowloaded the files from http://ftp.squeak.org/various_images/Seaside-Magma-Pier/ and http://ftp.squeak.org/current_stable/win/Squeak3.9-win32.zip But I got stuck again at the same place: There is a magma direectory created, and it contains for files: applied.images, commitPackages, objects, objects.idx. Ignoring the error message: I clicked on 'create'. I got: Clicking on Ok I get again: The top of the stack is included below. The generated error is at: ..................... MATransactionalFileStream class fileStream: aFileStream aFileStream ifNil: [ MaUserError signal: 'fileStream required' ]. ^ self new setFileStream: aFileStream ; yourself ..................... aFileStream is nil. The calling method is: ...................... openFile: unqualifiedName | answer | answer _ MaTransactionalFileStream fileStream: (directory fileNamed: unqualifiedName). answer ifNil: [ MagmaEnvironmentError signal: 'Could not open files in ', directory pathName ] ifNotNil: [ answer binary ]. ^ answer ...................... I inspected 'directory fileNamed: unqualifiedName'. It indeed returned nil... directory is set to DosFileDirectory on 'C:\dev\Squeak\SMP\magma'. As far as I can see this is correct. unqualifiedName is set to 'objects'. This also seems correct, and the file exists. I attempted to follow the issue with the debugger: The method MultipleByteStream open: fileName forWrite: writeMode fails at: fileID := StandardFileStream retryWithGC:[self primOpen: f writable: writeMode] until:[:id| id notNil] forFileNamed: fileName. fileName looks ok but fileID is nil. Of course at this point the file might be locked from the previous failure...
