Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I have a Mach-O bundle library that depends on an external dynamic library (qt) and a third-party framework (Cg). This bundle is loaded from a CFM host application (using CFBundleCreate and CFBundleLoadExecutable). This seems to work on my machine, as I have a full qt installation. But I would like to embed the qt library and Cg framework inside my bundle, as you would for a standalone application. I have tried using install_name_tool, as is required for a standalone app, but this does not seem to help. On another user's machine, the bundle cannot be loaded. Are there any special steps required to create a self-standing bundle in this way? I'm just looking to see if I'm doing things properly before I start exploring other possible problems.

The other problem that I have is that I need to tell the cardbus/IOPCardBridge to look for cards already inside the slot and to activate them. Basically simulate an insert of a card. The reason for this is that the tool I'm writing is used for testing GSM PC Cards and the test suite requires to power off the card at a certain point and then activate the card again. Due to the fact that no one is sitting in front of the machine during the test to pull out the card and push it back in I need some call (to be called from User space) to tell the OS to research for cards already in the slot. I need to write a command line tool which simply ejects (powers off) a specific PC card which is in the PC card slot. Basically I need the same functionality as the "PCCard.menu" extra when you choose "Power off Card" from the PC Card menu icon in the menu bar. Does someone know how to do this? printf("PCCardEjectCard called for socket %s (%p)\n", info->name, info); if (ejectCommand) { CFDictionarySetValue(ejectCommand, CFSTR("eject request"), CFSTR("value ignored")); err = IORegistryEntrySetCFProperties(info->service, ejectCommand); } -rick __ rick sulack darwin core os group apple computer, inc -------------------------------------------------------------- "More computing sins are committed in the name of efficiency (without necessarily achieving it) than for any other single reason - including blind stupidity" -Wulf 1972 This email sent to site_archiver(a)lists.apple.com

Has it always been this way? It seems rather odd to change from a good syntax which is fairly standardised, to a poor syntax which wasn't used anyway. :) On Fri, 14 Jan 2005 19:00:02 +1000, Chris Bergmann <ceebers(a)mac.com> wrote: It appears that gcc 4 has an issue with casting lvalues: Is this expected behaviour?
