Hi,

You probably did not install the glew library or do not have a recent enough version.

Please note that this forum is for announcement of (working) user application that you would like to share with the rest of the community.

No I have the lastest version of glew (1.6) installed by macports …
The strange thins is that the error occur only on the installation of root by source where

./configure options are :
<Dario.Moricciani@Dario-Moriccianis-MacBook:~/Desktop> root-config --config
macosx64 --enable-builtin-pcre --enable-cintex --enable-explicitlink --enable-genvector --enable-krb5 --enable-mathmore --enable-mysql --enable-python --enable-qt --enable-reflex --enable-table --enable-builtin-freetype --enable-ruby --enable-minuit2 --enable-roofit --enable-unuran --enable-qtgsi --enable-gdml --enable-soversion --with-f77=/opt/local/bin/gfortran-mp-4.5 --with-fftw3-incdir=/opt/include/include --with-fftw3-libdir=/opt/local/lib --with-pythia6-libdir=/Users/dario/software/pythia6 --with-pythia8-libdir=/Users/dario/software/pythia8140/lib --with-pythia8-incdir=/Users/dario/software/pythia8140/include --with-gsl-incdir=/opt/local/include --with-gsl-libdir=/opt/local/lib --with-qt-incdir=/opt/local/include --with-qt-libdir=/opt/local/lib --with-gviz-incdir=/opt/local/include --with-gviz-libdir=/opt/local/include --with-glew-incdir=/opt/local/include --with-glew-libdir=/opt/local/include

While the binary installation work fine. That means there is some problem on the build procedure.

I am sorry but where I have to post my question ?
