Always has been, probably always will be. This is fine if you want a hand-built kernel and don't mind having to manually save the config used for a given build and keep track of them over time. For development work that's normally convenient but if you're doing this regularly to simply use the builds and want to keep track of your changes and ensure they don't get mixed up or lost (what config options did I enable in build x.y.z-foo??) using the SRPM and rpmbuild is easier (you could also use a VCS but since the original question related to RPM builds that doesn't seem to be the case). Running an rpmbuild -ba will generate a new SRPM so as long as you keep track of release numbers and preserve the SRPMs you can always go back to see how a given binary RPM was configured (you also get the used config-* included in it).

It's possible skype is erroneously(?) using the pulseaudio corking feature when playing it's audio. ie, normally you want your other audio to stop to take a call, for example. see also, http://lists.freedesktop.org/archives/pulseaudio-discuss/2011- June/010300.html To disable that feature, edit /etc/pulse/default.pa and comment-out the line referencing load-module module-role-cork -- rex -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

make is invoked from kernel.spec file like this:
make -s ARCH=$Arch V=1 %{?_smp_mflags} $MakeTarget %{?sparse_mflags}
make -s ARCH=$Arch V=1 %{?_smp_mflags} modules %{?sparse_mflags} || exit 1
where %{?_smp_mflags} is:
1 core : -j 1
2 cores: -j 2
4 cores: -j 4
...
You can see multiple make proccesses. But only 2 (in my case) do the real
work:
user1 22073 12810 0 13:13 pts/000:00:00 make -f scripts/Makefile.build
obj=fs
user1 24474 22073 0 13:15 pts/000:00:00 make -f scripts/Makefile.build
obj=fs/cifs
user1 24530 22073 0 13:15 pts/000:00:00 make -f scripts/Makefile.build
obj=fs/coda
Make proccess with pid 22073 only invoke two addititonal make proccesses
which call cc1:
user1 3617 3616 0 13:21 pts/000:00:00
/usr/libexec/gcc/x86_64-redhat-linux/4.7.2/cc1 -quiet -nostdinc
user1 3627 3626 0 13:21 pts/000:00:00
/usr/libexec/gcc/x86_64-redhat-linux/4.7.2/cc1 -quiet -nostdinc ...
One cc1 -> one core or you called make with -j 1.

annotate pdf files - best options for use with F17?
Hi, I am required to annotate a pdf file for proof-reading and I was wondering what users would recommend for easy use with Fedora 17. I looked online some and came up with xournal, PDFescape, Crocodoc: the last two are some online resource. I tried xournal but was not impressed. Any suggestions?

Subject: Multi-Threaded make
While building the kernel from source RPM, I run
the command ps -ef | grep make in another terminal,
and I do see that 4 make processes are running, with
each one building objects for a different kernel source
directory.
However, something else seems to be single threaded
which is causing the huge delay in finishing kernel build.
I found that when I run top to see the upper-most
cpu consumers, I see only one cc1 process at the top.
So I ran ps again to see how many cc1 processes there
are.
Always - just one cc1 process.
I would expect to see anywhere from 1 to 4 cc1 processes
at a time. But that is not the case.
What is forcing only a single instance of cc1 at a time?
I hope the devs can have a look at either the compiler
tools or the make util.
make is invoked from kernel.spec file like this:
make -s ARCH=$Arch V=1 %{?_smp_mflags} $MakeTarget %{?sparse_mflags}
make -s ARCH=$Arch V=1 %{?_smp_mflags} modules %{?sparse_mflags} || exit 1
where %{?_smp_mflags} is:
1 core : -j 1
2 cores: -j 2
4 cores: -j 4
...
You can see multiple make proccesses. But only 2 (in my case) do the real
work:
user1 22073 12810 0 13:13 pts/000:00:00 make -f scripts/Makefile.build
obj=fs
user1 24474 22073 0 13:15 pts/000:00:00 make -f scripts/Makefile.build
obj=fs/cifs
user1 24530 22073 0 13:15 pts/000:00:00 make -f scripts/Makefile.build
obj=fs/coda
Make proccess with pid 22073 only invoke two addititonal make proccesses
which call cc1:
user1 3617 3616 0 13:21 pts/000:00:00
/usr/libexec/gcc/x86_64-redhat-linux/4.7.2/cc1 -quiet -nostdinc
user1 3627 3626 0 13:21 pts/000:00:00
/usr/libexec/gcc/x86_64-redhat-linux/4.7.2/cc1 -quiet -nostdinc ...
One cc1 -> one core or you called make with -j 1.
Gabriel
That does not make sense.
I have a unicore!! An old Athlon64 3700+,
and yet ps -ef shows up to 4 makes running at a time.

Re: slightly OT - user-specific postscript config files?
Hi, problem (below) solved: blasted away my $HOME/.cups directory, allowing things to default to /etc/cups/lpoptions, and all is back to normal... === Cameron Mura wrote (on 11/28/2012 09:39 PM): === Hello, apologies for this being slightly off-topic (I work in Fedora, so this list occurred to me as one place to ask the question...) In a nutshell: I'm wondering if anyone could point me to useful resources that describe where user-specific Postscript information/customizations/etc. are stored on a standard, vanilla Fedora installation ? I really do mean /user-specific/ (not global) preferences here, so I imagine the info/settings probably live somewhere in $HOME/, but my Linux/Fedora print config knowledge has become outdated and quite rusty... I tried some obvious things -- like blasting away the $HOME/.gtklp that exists if one has GtkLP installed (this is a GTK frontend to CUPS) -- but all this was to no avail, my page-scaling problem persists. I've also searched extensively online for the info (queries like "linux postscript user customization file"), but still can't find anything. A bit of backstory: Suddenly, any email I print from Thunderbird, by sending to the default print queue, ends up being scaled-down by a factor of ~0.8x, positioned flush-left and flush-bottom on the standard-sized (8.5"x11" letter) paper. I learned the following from various troubleshooting efforts and tests: 1. problem is not the printer itself -- e.g., a simplex queue on the same printer works fine (problem is I use duplex) 2. problem is not Thunderbird-specific -- I initially thought I must have mung'd a t-bird setting in prefs.js or something like that, but turns out that's not the problem -- interestingly, this scaling problem does /not/ occur if I print a PDF file to the troublesome print queue, but it /does/ occur if I print a postscript file from any postscript-aware app (e.g. okular), which led me to conclude it's some generic postscript config problem... 3. problem is not global, but rather is user-specific -- the scaling problem does not occur with another user account on the same machine >From the above I deduced it's some user-specific Postscript weirdness, and was hoping this could be traced to something in $HOME, but for the life of me I can't get any further maybe I'm missing something obvious?!? ...any tips or pointers to online resources would be greatly appreciated! thanks, cam -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

All apps should work, regardless of NM or network.service being active, as long as everything is configured so that the latter two don't clash into each other. If Xorg or other things crash, it's a separate issue. For one thing, Xorg should be operational for an offline machine as well as an online one (although maybe it requires the loopback interface to be active, I'm not sure).

Yes, this I had already done.

If Xorg or other things crash, it's a separate issue. We'll see if it happens again with Xorg next time I restart. Unbelievable it would seem so reliant upon NM.

Maybe he should run:

and see it that tells him anything about parallel or parent-child.
He's clearly unwilling to take lack of a "-j blah" option to be a clue.

Make is much more constrained by disk I/O than by CPU load. Setting -j to be
equal to the number of cores/CPUs is just playing it safe. This is especially
true when building a rpm which involves not just compiles and link but also
packaging, dependency resolution and documentation tasks which are even more
disk I/O intensive than compiles. Chances are that several of these operations
that not dependent on successfully compiling the code are fired off in parallel
rather than doing them sequentially and that old workhorse make gets the task of
managing each of these tasks. Thus, you end up with multiple copies of make
running at the same time even on a single core/CPU system to perform these
tasks.
Now just to totally blow your mind... while working with the 2.5.X development
kernels prior to the release of 2.6.0 I was doing at least one kernel build for
each new point release (sometimes more if there were build issues to resolve).
At that time my primary desktop was a dual CPU (back in the day before multiple
cores) Athlon rig. Since I had all sorts of time and plenty of trials to
experiment with I played around with the setting of -j for kernel builds. My
best results were with -j 12.

Bash - an odd problem using sed or awk or for
Hello, I have a bash script in which a variable is set to one or more lines of text. What I want is to remove any lines up to and including a blank line (or alternatively to echo all the lines after the last blank line). There may be zero or more blank lines, and the blank lines need not be consecutive. If there is no blank line, then all the lines should be shown. If the last line is blank, then nothing should be shown. So for example the variable may contain: (the '=' are not part of the variable) abc def hijk xyz So in this case what is wanted is: hijk xyz to be shown. I tried something like: echo "$XX" | sed -e '/./,/^$/d' but this didn't display anything. (Where XX is the variable.) I also tried using a 'for' loop but again this displayed nothing: opt="" IFS=$'\n' for n in $XX; do test -z "$n" && opt="" || opt="$opt $n"; done (Echoing $opt after this shows that it contains nothing.) I'm not sure why but even using a for loop just to show it had seen a blank line didn't work either (using something like 'test -z "$n" && echo found'). My understanding was that by setting IFS to a newline, then the 'for' loop should see the blank line and just set '$n' to the null string. We should then be able to test on that. Ideally what I am looking for is a snappy one line 'sed' or 'awk' command to handle this :-) Unfortunately at the moment I seem to be getting nowhere though, even with the 'for' loop.

I don't use Gnome (especially not this new one), but you should have an icon somewhere in the "system tray" (or whatever is equivalent in Gnome3), showing the status of the network. You can left- or right-click on it, and use available menus to access any configuration-related GUI for NetworkManager.

I disagree with you here. You build a rpm in stages: "%prep", "%build", "%install", "list check for %files" and packaging (dependency resolution/debug-info/etc). Each stage is dependent on the previous one. All the stages are run sequentially. make (%build stage) and make install (%install stage) may run things in parallel. But this is something else (as I understand the process). > Thus, you end up with multiple copies of make running at the same time > even on a single core/CPU system to perform these tasks. Exactly.

Oh, for a simple variable this should work
echo "${XX/*
}"

What I want is to remove any lines up to and including a blank line (or alternatively to echo all the lines after the last blank line). There may be zero or more blank lines, and the blank lines need not be consecutive. If there is no blank line, then all the lines should be shown. If the last line is blank, then nothing should be shown. So for example the variable may contain: (the '=' are not part of the variable) abc def hijk xyz So in this case what is wanted is: hijk xyz to be shown. I tried something like: echo "$XX" | sed -e '/./,/^$/d' but this didn't display anything. (Where XX is the variable.) I also tried using a 'for' loop but again this displayed nothing: opt="" IFS=$'\n' for n in $XX; do test -z "$n" && opt="" || opt="$opt $n"; done (Echoing $opt after this shows that it contains nothing.) I'm not sure why but even using a for loop just to show it had seen a blank line didn't work either (using something like 'test -z "$n" && echo found'). My understanding was that by setting IFS to a newline, then the 'for' loop should see the blank line and just set '$n' to the null string. We should then be able to test on that. Ideally what I am looking for is a snappy one line 'sed' or 'awk' command to handle this :-) Unfortunately at the moment I seem to be getting nowhere though, even with the 'for' loop. Thanks, John. John, this is easily accomplished, but you are not telling us where and from what source is your variable being set. For example, are you reading the lines in from a file or from stdin? If so, then I would get rid of lines containing any space(s) as follows: while read line; do set $line [ $# -lt 2 ] && echo $line done < SomeFile If reading from stdin, then you only need done (without the < SomeFile). It will print only the lines that lack a space. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Re: Multi-Threaded make
JD gmail.com> writes: > For the last time: > rpmbuild has no -j anything option!!! > JD - Calm down. Have a glass of wine or a beer or whatever. Noone is saying rpmbuild has a -j option. Several of us are trying to explain to you that programs like rpmbuild can do things that the end user may not realize are happening. If you wish to learn from our experience, we'll attempt to answer your questions. If not, don't expect much help. Back to the question at hand. Depending on the nature of the rpm being built, rpmbuild may spawn several make processes that run in parallel. You are seeing this when you run ps during your build. You probably have no control over this although there MAY be options for invoking rpmbuild that control this. What I was attempting to explain is that tasks with significant I/O can frequently run in parallel even though there are fewer CPUs than tasks. Several tasks can be waiting on I/O and the CPU is idle which means doing something else MAY decrease the overall time the rpm build takes. I used the example of building the kernel to illustrate this; nothing more.

Re: Disabling NetworkManager

It was bloody obvious from the first time I ever saw the Gnome desktop after log-in. And barely different from other releases of Gnome, as far back as Fedora 9, at least. There's an icon of two computers networked together on the taskbar, it represents your network. Depending on whether you left-click or right-click on it, you get different options.
