I have installed lilypond 2.14.1 on my Fedora 14 machine, as per the lilypond instructions for linux. When I run lilypond, it gives the following error message. /usr/local/lilypond/usr/bin/lilypond: error while loading shared libraries: libgmp.so.3: cannot enable executable stack as shared object requires:Permission denied I see several threads here already about executable stacks. I have already tried execstack to set/clear the flag for that shared object. Neither allows lilypond to run.

I'm working with some basic stack overflows. The following code compiles & runs fine in a non-ubuntu VM that's has no security features installed. On Ubuntu 10.04 it segfaults every time.

How Do I make a file a executable program ?
View 3 Replies View RelatedI've installed a few too many interesting items with Yumex into Fedora-14..
When I click to download an interesting pix, for my editing hobby, I get this here pop-up after saving the pix:
"The program executable (null) could not be found. Make sure that ClamAV/ClamWin is installed properly and check the Fireclam settings."
I searched Yumex for Clam and Fireclam, and they aren't installed, and I don't want it installed, because Clam slows-down the operation a lot in these prehistoric old towers...
Seems I installed a peripheral for Null and Clam, but what could it be..? I've searched through Yumex.. I just can't figure it...
I installed all the "nulls", hoping that would eliminate that irritating pop-up.. It didn't... Seems my only option is to reinstall the OS to get rid of the pop-up.. Is there another option?..
I have 3 c++ files, classdef.h (header file with class definition), methods.cpp (class methods) and program.cpp - the program itself. Both .cpp files have

I have Wine installed, but I can not open the file as it is blocked from executing with a window popping up telling me that this file was blocked due to security reasons. I go into the files properties and try to change the permission but that does not help. Is there a way to get around this? Possibly in the terminal as root?
View 3 Replies View RelatedI installed the latest version of Thunderbird by downloading the tarball and copying the contents to the required folder and just point launchers to the Thunderbird file.
However I cannot get GNOME Do to run Thunderbird. When I type run in Gnome Do, I go through the entire list without having Thunderbird as an option. The only plugin I can find is one that allows you to copy Thunderbird contacts to the clipboard.
I have set Thunderbird to be my default mail client, so when I type an email address I can choose to compose a mail in GNOME Do, but just opening up Thunderbird to check mail is not possible.

In GUI configuration tool it is set to disabled and grayed out so that there is no way to enable it there. Is there another way to enable SELinux?

I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine.

Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
