Try valgrind. It's an excellent memory instrumentation system which can trace back programming mistakes with complete callstacks of the offending site if you compile with debugging symbols.

Does > anyone know how I can prevent scons from trying to make these files or > how I can fool scons into thinking that it could? I'm a SCons user so maybe I can shed some light on the issue. SCons uses content signatures rather than time stamps by default, that is it detects file changes by accumulating MD5 signatures of preprocessed data (i.e. with dependencies). This doesn't work very well on directories such as /usr, but SCons suppresses these errors by default since it's a normal situation on UNIX-like systems. The usual way is to move the include paths from SCons' CPPPATH construction variable to the CXXFLAGS (or CCFLAGS). This way SCons doesn't get to see the directories and therefore ignores the files during the dependency scan. You can also change the target signatures method to use time stamps ranther than content stamps. A good resource for making these modifications would be the scons site at www.scons.org and the wiki on the same site which has lots of information.

'localhost' is mapped to 127.0.0.1, so probably the cups admin port is bound to 127.0.0.1 only. You can verify that with "netstat -ta".

If the remote partition is mountable, I think you'll be better off by taking a tar copy of the file system so that you're not constrained to restoring it on the exact same size. Try something like this from your "local" machine (assuming the other machine is called "remote"): ssh [EMAIL PROTECTED] '(cd /src && tar zcfp - .)' > backup.tar.gz (You can omit the 'z' option if compression isn't important.) If you do want to transfer the entire partition, I would recommend you restore the data using a reverse of the above from a loopback mount of that partition file (see the mount man page). This has the added advantage that is allows you to change the filesystem type and/or parameters of the target disk rather than just dumping over the old partition. However, to transfer the entire partition, you could do something like this: ssh [EMAIL PROTECTED] cat /dev/sdc7 > mypartition or compress it as well (on the remote side) using: ssh [EMAIL PROTECTED] 'cat /dev/sdc7 | gzip -9' > mypartition.gz Disclaimer: all of this is untested, but it shouldn't be too far off from a usable solution :-) Hope this helps, Andreas -- gentoo-user@gentoo.org mailing list

Are there any evidence of said bloat and poor performance with 4.0 or do you base it on hearsay? :-) I studied a lot of assembly output on the pre-release versions of 4.0 and the optimizer has really improved compared to the older series. I would imagine stuff not compiling is mostly because the C++ standard has moved considerably over the last years, and a lot of software which caters for GCC 2.95 isn't well-formed given the latest revision of the standard. That said, it usually takes a minor revision (i.e. 4.1) before a compiler is generally usable for a distro. I remember all the breakage when GCC 3.0 was introduced.. // Andreas -- gentoo-user@gentoo.org mailing list

Thanks, Richard This has to do with the printing support of samba, your smb.conf is probably configured to share printers as well as files, and when samba tries to access the print spooler to find out what printers are available it fails to connect. Samba regards this as non-fatal as it can still provide useful services by sharing files and directories. You should be able to find more information about samba's printing support in their HOWTO or FAQ documents. Regards, Andreas -- gentoo-user@gentoo.org mailing list

Shame ICC support is only in a couple of > packages and not more widespread. I wouldn't want to start a flamefest, but I've had a lot of experience with the ICC compiler over the last year working on the Battlefield 2 game engine (I used ICC under Linux) and I thought I'd add my two cents. There are a number of issues with using ICC on large C++ codebases. The most important ones I encountered are, in brief: - It sometimes generates invalid DWARF debugging sections, which crashes both GDB (all versions) and Intel's own debugger, idb. Not very helpful. - It sometimes generates broken assembly code (with duplicate assembly labels) that will not assemble, especially when you use floating point intrinsics (which are on by default). The only remedy is to move certain parts of expressions around. - It silently violates floating point IEEE requirements on the default optimization level (by using SSE single precision). This breaks many programs to the point where they see NaN values everywhere. I'm just trying to show that it's not all roses. For instance, I wouldn't expect something as large as openoffice or mozilla to compile and run successfully with ICC anytime soon unless major dev work goes into porting and babysitting those builds for ICC. On the positive side, ICC has excellent ANSI/ISO C++ support (it's based on a very good frontend which is also shared by Comaeu C++ IIRC), and when you care about speed more than correctness, it's very hard to beat. // Andreas -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Wacky Mouse...
Hi,
while I don't know what's causing your specific problem, this sounds a
lot like the behavior you would see back in the day when you set the
mouse protocol to PS/2 when the mouse device was really a serial
mouse, or vice versa.
Try changing the mouse protocol in the xorg configuration file and see
if that helps.
Regards,
Andreas
