pstack missing from Ubuntu 10.10
Hi All
I would like to use the tool "pstack" to get a sample of the stack trace for a process.
As far as I understood It seems widely available in all Linux systems, but it is not in Ubuntu 10.10.
I tried using apt-get as per some posts in few forum, but it cannot be found in the APT repositories.

I found this link here https://launchpad.net/ubuntu/+source/pstack/1.2-1 but I see 3 files:
A => 1 .dsc file that I don't know what does it mean
B => 2 different source tarball ( 1 ORIGINAL + 1 DIFF ?!?! ). I guess that they must be installed one after one in strictly order.

Is there any safe way to install it into my Ubuntu?
Any package that contains it that can be found via APT-GET?
Thanks a lot
Regards

According to the Launchpad site it should be available in Maverick (10.10) in the universe section. Could you post your /etc/apt/sources.list?

As for the files you've found: the .dsc is a general description of the package, the first tarball is the original source, and the second are the changes made by the packager to better fit into the distribution. You'll have to run dpkg-buildpackage on it to create an installable .deb.

Hm, you have the universe repo enabled. Did you run apt-get update after changing your repository list?

Auchh...no.
I did it after your advice but still calling
Code:
sudo apt-get install pstack

I don't get anything back.
I am trying to build the files shown in the web site.
I downloaded the files and called
Code:
me@myPc:~/myFolder$dpkg-source -x pstack_1.2-1.dsc

gpgv: Signature made Fri 08 Oct 2004 19:00:15 BST using DSA key ID AB474598
gpgv: Can't check signature: public key not found
dpkg-source: warning: failed to verify signature on ./pstack_1.2-1.dsc
dpkg-source: info: extracting pstack in pstack-1.2
dpkg-source: info: unpacking pstack_1.2.orig.tar.gz
dpkg-source: info: applying pstack_1.2-1.diff.gz
dpkg-source: info: upstream files that have been modified: 
 pstack-1.2/pstack.c

After then I try to build the library
Code:
cd pstack
make

cc -Wall -DVERSION=\"1.2\"  -g -o pstack pstack.c
pstack.c: In function ‘loadSymbols':
pstack.c:505: warning: cast from pointer to integer of different size
pstack.c: In function ‘crawl':
pstack.c:544: error: ‘EIP' undeclared (first use in this function)
pstack.c:544: error: (Each undeclared identifier is reported only once
pstack.c:544: error: for each function it appears in.)
pstack.c:546: error: ‘EBP' undeclared (first use in this function)
make: *** [pstack] Error 1

From the README files I see that they need ELF library. I installed them already but still it cannot compile. I might probably using a wrong one or what?

Ugh, sorry for not noticing this earlier, but which platform are you running on? Because there's a bug report for pstack on AMD64 platforms.

To properly (attempt) to build a package, run this
Code:
sudo apt-get install fakeroot build-essential dpkg-dev    # Install required programs to build
sudo apt-get source pstack    # Get the source
sudo apt-get build-dep pstack    # Get possible required extra programs for the build
dpkg-source -x pstack*.dsc    # Unpack/patch the source
cd pstack-<version>
dpkg-buildpackage -rfakeroot -b    # Build a .deb
dpkg -i ../pstack*.deb    # Install the package if all went well

I have INTEL based on this call
Code:
cat /etc/proc/info

model name    : Intel(R) Core(TM)2 Duo CPU     E8500  @ 3.16GHz

but executing the list of commands you are suggesting I see a suspect file called
Code:
pstack_1.2-1_amd64.changes

and other errors so the procedure is not successfull ( I am going to retry again ).

If you see code below is noted where is produced.
