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.

Auchh...no.
I did it after your advice but still calling
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
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
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
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
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
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.

What's the output of uname -a ? Because I think this is only a perceived "error": the 64bit architecture used in current personal computers was developed by AMD, not Intel, and is called AMD64 for that reason. Intels own 64bit architecture, Itanium, never really caught on outside of high-end servers (the ones where you pay more for the OS than for a mid-range server hardware).
