It's a true statement, ethernet is not necessary, if you keep the PC with the USB printer running when you need to print. I've used both Linux & MSWindows as print servers. If memory serves WinXP was able to offer 'Print Services for Unix', their name for LPD, to allow any USB printer connected to the WinXP PC to be accessed by Linux clients using CUPS. I didn't even have to install Samba on the Linux PCs, vanilla CUPS worked fine. Of course the reverse is also true as Peter mentioned. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
[gentoo-user] ...I not allowed to make pdfs from images??????
Hi, from some images I want to create a pdf. I found this commandline to do so (imagemagick): convert 1.png 2.ong 3.png result.pdf If I do so I got this message: convert: attempt to perform an operation not allowed by the security policy `PDF' @ error/constitute.c/IsCoderAuthorized/408. What the heck... How can I allow myself to work on my compyter ? ;) Cheers! Meino

This option means that gcc is determining the type of CPU automatically and adjusts the instruction set used to exactly this CPU. Although, in your case, it is highly likely that your new CPU understands all commands from the old, but I wouldn't bet on it. Its possible that your existing software encounters problems like "illegal instruction" or the like. Very bad if your compiler crashes after CPU replacement, then you cannot emerge anything.

Since I got time, I'll change the CFLAGS for at least the @system stuff, that should get me booted for sure. While the native setting makes things easier for normal use, I can see the point of not using it when changing CPUs. That is one reason for this thread. The CPUs are different and may require some changes during the swap. Is there a easy way to see what if any changes will be made? I did a emerge -UDNa @system but it's not showing any change. Does it require a emerge -e @system to force the change? Or is it not changing anything? Thanks much. Better safe than sorry. ;-) Dale :-) :-)

But there's still the problem that the stable version of kstars does not check the correct version of indi and compiles a version not supporting it although the use flag has been set. Do you create a bug report for kstars or shall I do it? Alex

I am not aware of a simple way of only doing those, so a "emerge --empty @world" will be needed. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Based on the output, that's what I was thinking. Emerge picks up on other USE changes but it seems it only grabs the CFLAGS during the compile/configure phase for each package. Would this change the kernel image as well or would it remain the same? I may build a new kernel just to be sure. One good thing about this, I can compare the times with current CPU and new CPU later and get a rough idea of speed increases. ;-) Pardon me while I generate some heat. o_O Dale :-) :-)
