Date: Sun 12-Jan-1989 19:54:29 From: Unknown Subject: extra terminal launch When I double-click from the browser to launch an application I have built with the Interface Builder (e. g., the Celsius to Fahrenheit calculator), it is always accompanied by the automatic launch of an extra terminal process, complete with window and menu, followed by the requested application's displays. Does anyone know why this happens? When I execute the application from a terminal window with a csh execution command, I don't get the extra terminal launch. >From: ali@polya.Stanford.EDU (Ali T.

Does anyone know why this happens? When the Workspace is launching an app, if it doesn't recognize the app as a Mach executable, it assumes the app cannot be run directly. So a Terminal is started and the app is run in the Terminal. (Or at least that's what it seems like. Amiga users will recognize this as the same kind of thing that happens when XIcon or IconX is used to automatically start a shell to run programs that cannot be directly run from the Workbench.) By default, the IB generated Makefile lacks the few lines of magic that makes an executable into a Mach executable. Take a look at some of the makefiles in /MyDisk/Programming/Examples/*. Some have LFLAGS (or LDFLAGS; these are the command line options that get passed to the linker) are set to something that looks like: LFLAGS = -g -segcreate __ICON __tiff foo.tiff __ICON __header foo.header (This is from memory; so please double check.) The "-g" is debug; the rest of the flags specify the creation of a Mach segment called "__ICON" which holds icon-image information for this program. "foo.tiff" and "foo.header" are two files which contain information about the icons; you can, if you wish, simply replace those two files by an zero-length file. This way you get a Mach segment, preventing the Terminal window from appearing during launchtime. (But you won't have a custom icon for your app.) You can automate the creation of a such a zero-length file with a "touch" appropriately placed in the Makefile; some examples do this, I believe. This stuff isn't very well documented, even in the official Tech Docs for 0.8, mainly because it's all going to be automated or somehow made easier in the future. Workspace behaviour might also be changed for non-Mach executables. Ali Ozer, NeXT Developer Support aozer@NeXT.com >From: dorner@pequod.cso.uiuc.edu (Steve Dorner)

Perhaps IB does this automatically so that there is always a window open in which you can run the GDB debugger? Have you tried checking the "Interface Data" box when when you decompile and then remake everything? I don't know that this will help anything, but maybe whatever code is launching the extra terminal window will get left out if IB thinks you are going to build a "real" application.

Start subsequent Terminal/Shell applications by double clicking the appropriate icon (or name) in the browser window of the Workspace manager (after locating it, of course).

When you launch an app from the Workspace, if Workspace detects that the app does not have icon information, it assumes that the app is an Unix-style command and opens up a shell in which you can get the output or perhaps enter some input. For instance, you can double click on "ps" and get the output in the terminal window. Or you can double click on a shell script and have the script accept input in the terminal. This feature is of course somewhat limited; I don't know how it will change in the future. Ali Ozer, NeXT Developer Support >From: dorner@pequod.cso.uiuc.edu (Steve Dorner)
