Re: f22: ip route replace via line command not work
Il giorno gio, 04/06/2015 alle 14.15 +0200, Dario Lesca ha scritto: Now after update to f22 this command (ip r replace or delete) not work anymore. Also on a fresh install of f22 is not possible to change via line command the default gateway to point to another router. Is this a bug or is intentional ?

I installed gsl and gsl-devel, but didn't find any man pages, so I cannot
tell what it says (or would say) about how to call that function. As a
result, I had to guess.
perhps it wants you to locally allocate an actual structure instance

in that case, remove thne * from the declaration and add the to the call.

Hello,

This short piece of code fails.
It seems to be due to the gsl library!
Thank for your help.
#include gsl/gsl_multifit_nlin.h
int main () {
const gsl_multifit_fsolver_type *T_ ;
gsl_multifit_fsolver *s_ = gsl_multifit_fsolver_alloc (T_, 10, 1);
}
You haven't initialized T_, so when you call
gsl_multifit_fsolver_alloc, it fails because it doesn't know what
solver type to allocate for.
So, try initializing it, eg.
const gsl_multifit_fsolver_type *T_ = gsl_multifit_fdfsolver_lmsder;
the other thought I had is that you may need to pass the address of
T_ so the function knows where your local gsl_multifit_fsolver_type
is, so it can store data there. Try passing T_ instead. In this case
you wouldn't need to initialize it because the routine will use
the address of your local variable.

So, you can find that in Fedora's Package DB; in this case, here: https://admin.fedoraproject.org/pkgdb/package/gsl/ However, I don't think this is a packaging problem. If it's a *bug*, the package owner might help you diagnose that and interface with upstream, but usually contacting upstream directly is the best approach. I think, though, that this might be a programming / usage problem, and for that you probably will have best luck asking either in the upstream community or in a programming qa site — I see that there are over 300 questions on GSL in Stack Overflow already http://stackoverflow.com/?show=allsort=newestlayout=expandedtagFilter=listtags=gsl -- Matthew Miller mat...@fedoraproject.org Fedora Project Leader -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

F22: Touchpad and Middle click
Hi, I've installed F22 on a Dell E5430 laptop. I've noted the following behavior upon text selection: - with an external mouse, the middle works as expected, that it pastes the currently selected text - with the touchpad (which has two buttons), the simultaneous pressing of left and right buttons does not paste the selected text as I expect (until F21 it worked) I've tried both on GNOME, XFCE and Cinnamon. I don't know if this may be a consequence of using libinput as described here: https://fedoraproject.org/wiki/Changes/LibinputForXorg I've found similar questions in the AskFedora and FedoraForum sites, but for both there is no answer yet. Anyway, does anybody have a tip to solve this issue?

it is linked with gsl and math library.
I guess that there is an issue either with the c code or with the binary
library.
Well, looking at the code, you're passing T_, which is uninitialized.
Not knowing the API for gsl_multifit_fsolver_alloc(), I have no idea
what params it's expecting, but that's a pretty good one to start
looking at.
In fact, there's two possibilities...passing in an uninitialized pointer
is suspect, and if the function is supposed to fill in whatever that's
pointing at with a value is also a problem as you've declared it as a
const, meaning you can't assign data to it at run time.
That is right.
I tried to not set it const, but it is the same result.
I tried to have a look in the code, but I did not understand what is going on.
I did not find any example.
Actually, I made similar things to that is proposed for
gsl_multifit_fdfsolver
which do not suffer from this allocation issue.
Who is in charge of this package?
Thank.

You almost need another one so you can research, on-line, how to fix up the other one when it goes doolally. If you're in that position, you may as well install a long-lived distro on one, and use it as your server. -- tim@localhost ~]$ uname -rsvp Linux 3.19.8-100.fc20.i686 #1 SMP Tue May 12 17:42:35 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.

f22: ip route replace via line command not work
Sometime I must try other network or gateway, since to f21 I have change the default gateway vie line command via command like this: ip r rep default x.x.x.x Now after update to f22 this command (replace or delete) not work anymore. See some example: [root@dodo:~]# ip r default via 10.44.0.247 dev p6p1 proto static metric 100 10.11.12.0/24 dev virbr0 proto kernel scope link src 10.11.12.1 10.44.0.0/20 dev p6p1 proto kernel scope link src 10.44.2.27 metric 100 [root@dodo:~]# /sbin/ip route rep default via 10.44.0.254 proto static metric 1024 [root@dodo:~]# ip r default via 10.44.0.247 dev p6p1 proto static metric 100 10.11.12.0/24 dev virbr0 proto kernel scope link src 10.11.12.1 10.44.0.0/20 dev p6p1 proto kernel scope link src 10.44.2.27 metric 100 [root@dodo:~]# ip r del default via 10.44.0.247 dev p6p1 proto static metric 100 [root@dodo:~]# ip r default via 10.44.0.247 dev p6p1 proto static metric 100 10.11.12.0/24 dev virbr0 proto kernel scope link src 10.11.12.1 10.44.0.0/20 dev p6p1 proto kernel scope link src 10.44.2.27 metric 100 Only the ip r add to another network work, or if I create a new NetworkManager profile without default gateway (probably is the new version of Network Manager responsible for this problem). It's possible to restore old manual method for change temporary the default gateway?

This short piece of code fails.
It seems to be due to the gsl library!
Thank for your help.

You haven't initialized T_, so when you call
gsl_multifit_fsolver_alloc, it fails because it doesn't know what
solver type to allocate for.
So, try initializing it, eg.
const gsl_multifit_fsolver_type *T_ = gsl_multifit_fdfsolver_lmsder;

the other thought I had is that you may need to pass the address of
T_ so the function knows where your local gsl_multifit_fsolver_type
is, so it can store data there. Try passing T_ instead. In this case
you wouldn't need to initialize it because the routine will use
the address of your local variable.

fsolver and fdfsolver are not compatible!
I did not find a way to initiate this pointer.
