Installation issues of new version root-6.06.00

ROOT
1

As I was trying to install root-6.06.00 on my Fedora 21 with gc version 4.9 and 32bit build using the following installation method:
[ul]wget root.cern.ch/download/root_v6.0 … rce.tar.gz
tar zxvf root_v6.06.00.source.tar.gz
export ROOTSYS=/home/…/pythia_root/root-6.06.00
cd root-6.06.00
./configure --enable-soversion --all --build=debug --with-pythia8-incdir=$PYTHIA8/include --with-pythia8-libdir=$PYTHIA8/lib > configure.out.txt 2>&1
gmake > make.out.txt 2>&1[/ul]

I am receiving the following error message after doing: gmake

[quote]In file included from /home/…/pythia_root/root-6.06.00/math/mathcore/src/MixMaxEngine.cxx:19:0:
/home/…/pythia_root/root-6.06.00/math/mathcore/src/mixmax.h:98:19: error: ‘__uint128_t’ was not declared in this scope
myuint mod128(__uint128_t s);
^
Makefile:655: recipe for target ‘math/mathcore/src/MixMaxEngine.o’ failed
gmake: *** [math/mathcore/src/MixMaxEngine.o] Error 1[/quote]

As I continue ignoring the error towards gmake install , it becomes obvious that lots of error would accompany which will cause the source not to be installed properly. I have already uninstalled the older version. So, what would be the cause? I am wondering if I am choosing a wrong version not being compatible with my system or missing other important notes in the above commands. Your help is greatly appreciated.

Hi,

Hi,

ROOT’s master and head of v6-06-00-patches now work on 32bit. We are planning a patch release 6.06.02 including this.

Cheers, Axel.

Thanks bellenot,
I was trying to avoid Cmake method in order to have an “in-place” installation of root which does not go into my /usr/local or …and that I can compile and run the code as a C code from command line. Would that be possible?
something like the following command that I used to invoke for my older version of root?

And thanks dear Axel, I can’t wait to see that release.

Sincerely,

Hi,

Sure, you can use the CMAKE_INSTALL_PREFIX variable. E.g.:

cmake -DCMAKE_INSTALL_PREFIX=/home/ashur/root-v6.06.00 [...]

[quote=“ashur”]something like the following command that I used to invoke for my older version of root?

g++ -Wall -o example example.C `root-config --cflags --libs`

[/quote]
This is independent of CMake

Cheers, Bertrand.

Hi Bertrand,
Somehow I thought, I need to do both of the following lines of command:

I did the first but noticed that I should have done the second instead for my desired method.
Do you know if I can undo the first command?

Plus I received the following error message at the end of first command:

[quote]Install the project…
– Install configuration: "RelWithDebInfo"
CMake Error at cmake_install.cmake:36 (file):
file cannot create directory: /usr/local/tutorials. Maybe need
administrative privileges.

Makefile:66: recipe for target ‘install’ failed
gmake: *** [install] Error 1
[/quote]

Thanks,

The resolution to my second concern (error message coming form first command) is found here
http://stackoverflow.com/questions/34886877/cmake-error-at-cmake-install-cmake31-file-file-cannot-create-directory-usr
So by disabling “roottess” option during cmake, we can resolve the issue. However, I am still confused as whether both commands should be entered or just the second one (related to my preference).

Thanks,

I solved the problem except that now after

I am receiving this error message:

[quote]CMake Error at cint/ROOT/cmake_install.cmake:42 (file):
file INSTALL cannot find
"/home/…/root5.34.32/lib/libvectorDict.so".
Call Stack (most recent call first):
cint/cmake_install.cmake:38 (include)
cmake_install.cmake:157 (include)[/quote]

What do you guys think?
I ignored the error and proceeded further and it seems that it works now. But, I did this only for v5.34.32.
I think I need to wait for Axel to let me know how long should I wait for 06.02 or …?

Thanks,

Hi,

No need to wait for me:

mkdir root
cd root
git clone http://root.cern.ch/git/root.git src
cd src
git checkout v6-06-00-patches
cd ..
mkdir build
cd build
cmake ../src
make -j8
. bin/thisroot.sh
root -l -b

Repeat the last two as often as you like.

Cheers, Axel

Thanks Axel for taking your time and being kind to put down all lines.
