Re: [Pharo-users] OSProcess on Windows

by Bob Cowdery

Hi Carlos Well, I think frustration is starting to creep in now. Everything I touch seems to croak in some way. I loaded ProcessWrapper as it seems to be the more recommended way on Windows. Still didn't get a plugin with it. Noted that 'ProcessWrapper downloadPlugin' is supposed to do that. That didn't work as it falls over on 'Utilities informUserDuring: '. Even when I took that out of the source it still fell over. Downloaded the plugin source and tried to build it but its missing libraries and I don't know which ones. Also it has a header file which can't be generated so I made one up but probably got it wrong. Oh, well, guess I will press on a bit longer.

Hi, I am interesred also in what you are trying to use, but had loaded ProcessWrappper and executed Excell passing a spreadsheet file as argument and got the inside VBScript running fine, but the Excel terminates too early because I could fid the way to control how the parent process may wait for the child to terminate.

OSProcess on Windows

by Bob Cowdery

Does anyone use OSProcess on Windows? If so can you tell me how to make it work please. OSProcess thisOSProcess command: 'cmd.exe /C notepad' Fails in two ways. It tries to output a message to stderr but fails to do so. The message it tries to output just says: "nextPutAll: 'cannot execute cmd.exe /C notepad'". I also tried to open a console with: OSProcess thisOSProcess openConsole but that seems to do nothing and gives no errors. Any help very welcome. Regards Bob

Re: [Pharo-users] VM/Settings for Deploy

by Sven Van Caekenberghe

Laurent, Mariano, Thanks for the reply. I read the various threads you both pointed to. This is not a good situation. A good VM (stable and performant) is absolutely critical to Smalltalk/Squeak/Pharo's success. A 30% speed difference due to some secret compiler settings is very scary for what is essentially an open source project, although I also understand that some people want to get some money back for their efforts. I can't imagine that recompiling the Linux kernel, Apache or PostgreSQL with some secret compiler settings or even another compiler would make so much difference versus the open way (although some minor speedup by tuning compilation to specific hardware is to be expected). I think (and Stef suggested as much since he mentioned buying the Intel C compiler) Pharo needs to deal with this to fullfill its mission of offering a free and open source attractive platform to build and deploy mission critical Smalltalk applications. On the other hand, I wouldn't mind paying a reasonable license/support fee if that would benefit the community as a whole at the same time.
