Upgrade CPAN for Perl in Raspbian Linux fails

I'm trying to upgrade CPAN in latest and most upgraded Raspbian. I run this on a Raspberry Pi A with 256 MB RAM of which 32 MB is graphics memory. Cpan doesn't complain about being out of memory, but it can't unarchive. I have installed gcc-4.7 which seems to be required to compile inside cpan. My goal is to install Tkx after upgrading CPAN:

. I've done this in Ubuntu

14.04 for x86-32. There is no libtkx-perl for Raspbian or Ubuntu, but there was for earlier versions of Debian:

Now I try to install Tkx using the old CPAN, but it locks me out of the system due to high CPU-load. When the screen-saver started I can't interrupt it. I can't login using SSH. I can't use the Alt+F1 terminal I run startx from since the screensaver can't be interrupted. I thought Linux prioritized user input, but I don't think Linux works that well if it locks out the user when the CPU-load is high -- it would be better if it compiled Perl-modules at a lower pace and let the user issue commands. Even if this would be due to low memory a good operating system would handle that by sending a message about low memory and then terminate the operation of cpan. Update: Now the installation of Tkx seems to have hung completely and the OS can't be contacted, but the green light for SD-card access is permanently on.

Is there anyone here that has succeeded in upgrading CPAN to 2.05. I think Perl without a useable cpan would be rather useless.

I configured cpan to use sudo -- the same configuration works in Ubuntu.

Here is the session:

which suggest a memory issue. Have you tried to add more swap- space?

Thanks, but I don't know how to add swap-space. Is it just to plug-in a USB-stick with a swap-partition? If it is an out of RAM-memory problem I think the error messages should be clearer.

Anyway I found a way to install Tkx usin cpanm. The installation runs fine with windows popping up to test functions, but then the programs I write fail with segmentation fault. I installed it in Raspbian with these command lines:

### sudo apt-get update && sudo apt-get install gcc-4.7 tcl8.5-dev sudo curl -L

CPAN and a linux distro's packages are not compatible because they use entirely separate methods for resolving dependencies. Using both in the same development system is a good way to bork your Perl set-up because its very unlikely that CPAN and the Raspbian package management will be in sync as regards library versions and patch levels.

In short:

- if you're going to use CPAN, start by uninstalling all the Raspbian Perl packages and only use CPAN as your source of Perl libraries, modules and updates.

- if you decide to stick with the Raspbian Perl package set, don't go near CPAN.

I prefer to stick with Raspbian. I could find a lot of modules by searching in aptitude for "-perl". Is there a way to list all packages that matches /lib.*-perl/ ?

I did find a Debian-method of installing from CPAN on

When I run this I was locked out of my system for a long time and couldn't even interrupt the screen-saver. I think this is extremely bad for an OS. Maybe this is a unique behavior for Raspbian on Raspberry Pi. I think they should reserve some CPU-time for the user to at least be able to kill the program.

Does `aptitude search lib.*perl | less` do the trick?

There is some group working on libtcl-perl for Debian:

Maybe one could get this to work in Raspbian.

I tried: git clone git://anonscm.debian.org/pkg-perl/packages/libtcl-perl.git cd libtcl-perl/ perl Makefile.PL make

I do have tcl.h on my system. find / -name tcl.h 2> /dev/null

Output: /usr/lib/perl5/Tk/pTk/tcl.h /usr/include/tcl8.5/tcl-private/generic/tcl.h /usr/include/tcl8.5/tcl.h

This works: cpan2deb Tkx

But after installation it doesn't work, and one gets segment fault when using it, even if I have the manually installed Tcl for Perl.

libtcl-perl exists in Debian testing and unstable, and also in Raspbian testing:

Well, you should try to build a Debian package from the Debian source :)

Interesting.

Ok, looking at the debian/rules file, there is some magic involved:

#v+ % cat debian/rules #!/usr/bin/make -f

TCLCONFIG=$(shell grep -Eo '/usr/lib/.+/tclConfig.sh' /usr/lib/tclConfig.sh)

%: dh $@

override_dh_auto_configure: dh_auto_configure -- --tclconfig $(TCLCONFIG) --no-usestubs #v-

Maybe you could try to build the package the debian way; after cloning the repo, make sure to have the Build-Depends installed [0], and then try to run `dpkg-buildpackage -uc -us'.

Alternatively you could try to simulate the parameters from debian/rules as perl Makefile.PL --tclconfig $(grep -Eo '/usr/lib/.+/tclConfig.sh' /usr/lib/tclConfig.sh) --no-usestubs

(Maybe only the --no-usestubs is enough ...)

It might need more RAM than you have, and be terribly slow to build, but perlbrew (installer in the repo) allows you to keep a separate, CPAN-compatible build of a recent Perl under Debian without screwing up the system /usr/bin/perl.

Thanks for trying to help!

I tested this but I did not get the information you got: pi@pi2 ~/libtcl-perl $ sudo apt-cache policy libtcl-perl N: Unable to locate package libtcl-perl

I installed the packages with: sudo apt-get install debhelper tcl tcl-dev perl

I tried this: pi@pi2 ~/libtcl-perl $ dpkg-buildpackage -uc -us dpkg-buildpackage: source package libtcl-perl dpkg-buildpackage: source version 1.02+ds-3 dpkg-buildpackage: source changed by Salvatore Bonaccorso dpkg-buildpackage: host architecture armhf dpkg-source --before-build libtcl-perl dpkg-source: info: applying fix_hardening_FTBFS.patch dpkg-source: info: applying wording.patch fakeroot debian/rules clean dh clean dh_testdir dh_auto_clean dh_clean dpkg-source -b libtcl-perl dpkg-source: error: can't build with source format '3.0 (quilt)': no upstream tarball found at ../libtcl-perl_1.02+ds.orig.tar.{bz2,gz,lzma,xz} dpkg-buildpackage: error: dpkg-source -b libtcl-perl gave error exit status 255

It didn't work. I tried this:

pi@pi2 ~/libtcl-perl $ perl Makefile.PL --tclconfig $(grep -Eo '/usr/lib/.+/tclConfig.sh' /usr/lib/tclConfig.sh) --no-usestubs Tcl config file '--no-usestubs' not found

It also did not work.

I could just wait until Raspbian is upgraded to Jessie.

I have the most updated system from the latest NOOBS: sudo apt-get update && sudo apt-get -y upgrade sudo apt-get -y dist-upgrade sudo rpi-update

It still says Wheezy though.

Reply to
M.O.B. i L.

Right, I guess you're on wheezy and I'm on jessie :)

Oops, sorry, I confused building a package from git and from a source package.

You can download the missing .orig.tar.gz e.g. from

formatting link

put it in the directory above the source tree and run `dpkg-buildpackage -uc -us' again.

Sounds like /usr/lib/tclConfig.sh doesn't exist. Interesting. Should be in tcl-dev. (But maybe not in wheezy.)

Or upgrade to jessie ...
