Installin applphoton with conda packages

[tgiani]

Hi, I m trying to install applphoton using conda packages. I ve created a new environment and I ve installed the conda packages for root:

conda create --name nnpdfroot 
source activate nnpdfroot
conda install cern-root

Then I ve cloned the repo and I ve tried to install the compilers, automake and libtool

git clone  https://github.com/scarrazza/applgridphoton.git
cd applgridphoton
autoreconf -i
./configure --prefix=/scratch/anaconda2/envs/nnpdfroot

Here there is the output of the last two lines

(nnpdfroot) bash-4.2$  autoreconf -i

Sounds like the gcc compiler is not able to compile, so I would say this is not related to the cern-root package. Are you sure you can compile c/c++ code? The conda package provides the root-config?

If i try to compile without creating a new clean conda environment I m able to compile c++ code, but then I will have problems in creating the applgrid grid, as reported in issue #5 in NNPDF/external.

I guess the problem in compiling c++ code is happening only when I m working in a new environment with nothing in it. Following the instructions of Zahari's email of some weeks ago i was trying to install the compilers, automake and libtool from conda, with these commands:

autoreconf -i
./configure --prefix=$CONDA_PREFIX
make
 make install

I don 't know if I m missing some steps.

If i try to run root-config from the conda env with the root packages installed i get

(nnpdfroot) bash-4.2$ root-config
Usage: root-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--cflags] [--auxcflags] [--ldflags] [--new] [--nonew] [--libs] [--glibs] [--evelibs] [--bindir] [--libdir] [--incdir] [--etcdir] [--srcdir] [--noauxcflags] [--noauxlibs] [--noldflags] [--has-<feature>] [--arch] [--platform] [--config] [--features] [--ncpu] [--git-revision] [--python-version] [--cc] [--cxx] [--f77] [--ld ] [--help]

so i guess that root is there

Just realised that maybe i should have referred directly to issue #5 in NNPDF/external, intead of opening a new one here
