Hm, that sounds like a file that you have write but not delete permissions to. Can someone look into this please, Well, just to state the obvious, /you/ would be the most ideally-placed person to do so. I don't even have Vista, so I'm kinda ruled out there, but I'd take a look at the perms and ACLs of conftest.dir and the existing depcomp file in there, using both 'getfacl' to show cygwin's view of the posix-style perms, and 'cacls' to compare with windoze's opinion. BTW, you didn't by any chance use winzip to unpack the tarball did you? cheers, DaveK -- Can't think of a witty .sigline today -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

The exception is the UAC stuff which could result in some executables having less permissions than usual, if, for instance, Internet Explorer has been used to download the executable. We can hopefully rule this out here, so it's just some permission problem which has nothing to do with the base OS. Note: Not all problems on Vista are Vista's (or, FWIW, Cygwin's) fault. See, for example http://cygwin.com/acronyms/#PEBCAK for one possible explanation of the problem.

The only things that are diferent are the Cygwin instillation and Vista. Note: Not all problems on Vista are Vista's (or, FWIW, Cygwin's) fault. See, for example http://cygwin.com/acronyms/#PEBCAK for one possible explanation of the problem. Nice reply :) Does look like a case of PEBCAK. Unmodified GCC 4.2.0 compiles okay, but when modified cracks appear, only on Vista though, XP is okay. So must be something to do with permissions.

Windoze tools don't generally do the right thing for cygwin's emulation of posix perms. Apart from that, the file permission settings are the same in Vista compared to older OSes.

We can hopefully rule this out here, so it's just some permission problem which has nothing to do with the base OS. I want to throw an AYS in Corinna's general direction here... one of the ongoing problems in 'doze security since wy back when is that the default perms for user-created files, the equivalent of the default umask under posix, have always been pretty wide open: AYS they haven't been tightened up for Vista? Works fine on XP. The only things that are diferent are the Cygwin instillation and Vista. Heh, so that's a bit like saying The only things that are different are everything, apart from the gcc source code. Unmodified GCC 4.2.0 compiles okay, but when modified cracks appear, only on Vista though, XP is okay. So must be something to do with permissions. So, what tool did you use to 'modify' it? cheers, DaveK -- Can't think of a witty .sigline today -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
