Release 5.32.03 on Ubuntu 12.04

ROOT
1

Dear all,
I tried to install the version 5.32.03 on Ubuntu 12.04, and I have several problems. I can’t run the codes.
Initially, not all libraries are loaded, then I manually loaded with
gSystem-> Load (“lib …”)
and I get:

root [6] gSystem -> ListLibraries ()

Now, when I try to run some tutorials, for example “gerrors.C”, I get the following message.

root [7] .x gerrors.C
Warning in TCanvas::Constructor: Deleting canvas with same name: c1
Warning in TCanvas::ResizePad: c1 width changed from 0 to 10

Someone could kindly help me?
Thanks,
Gianpaolo.

You didn’t write how you “installed” ROOT … and it seems to me that something is wrong in there …
In general, you have two choices:

  1. use my installation instructions (ROOT’s “etcdir” is automatically set to “${ROOTSYS}/etc”): [url]Installing ROOT from Source
  2. configure your ROOT adding “–prefix=/Where/You/Want/To/Install/It --etcdir=/Where/You/Want/To/Install/It/etc/root” (if you do not set “etcdir”, it will default to “/etc/root”, regardless of what your “prefix” is)
    See also:

Hi,
I have installed ROOT as follows:
I downloaded the source "root_v5.32.03.source.tar.gz"
and then:

cd root
. /configure
. /configure --prefix =/opt/ROOT/v5.32.03
make
make install

Hi,
I can’t solve my problem. Can you help me?

Try (build it in “/tmp/ROOT/root”, install it into “/opt/ROOT/v5-34-00-patches”) … cd /tmp rm -rf ROOT mkdir ROOT cd ROOT svn co http://root.cern.ch/svn/root/branches/v5-34-00-patches root cd root export ROOTSYS=/opt/ROOT/v5-34-00-patches rm -rf ${ROOTSYS} ./configure --enable-explicitlink --enable-soversion --all make make install cd /tmp rm -rf ROOT Then … cd source /opt/ROOT/v5-34-00-patches/bin/thisroot.sh root

Very good!!
Now everything works fine. The problem was solved.

Thank you!

Hi, quite a similar situ to that noted.

I’m running ROOT 5.32/00, gcc Ubuntu/Linaro 4.6.3-1ubuntu5 on 12.04 x86_64.

root [0] gSystem->ListLibraries();

My code (attached) compiles with g++ -o prune prune.cpp root-config --cflags --glibs
but upon execution…

So, I follow the instructions as set above for 5.34 … which installs fine, but shows:

root [0] gSystem->ListLibraries();

/opt/ROOT/v5-34-00-patches/lib/libMathCore.so

4 libraries loaded

with the same error as before. I know that the “Error in TBufferFile::ReadClassBuffer:” means the input is probably corrupted, but I would like first to squash the warnings & see if that helps.

A hopeless case, am I not? :wink:

In the beginning of your “main”, try to add (and don’t forget to “#include <TApplication.h>”):
TApplication a(“prune”, 0, 0); // just to make sure that the autoloading of ROOT libraries works

Hi, thanks for the swift reply.

int main()
{
TApplication a(“prune”, 0, 0);
(etc)

Unfortunately, no luck

g++ -o prune prune.cpp root-config --cflags --glibs

Try:
ldd ./prune
and inspect the returned list of libraries (in particular, make sure that all absolute paths to ROOT libraries point to your distribution).

Thanks, but it all seems legit.
