Loading libRGL.so on MAC OSX

ROOT
1

I have compiled root-v28c on MAC OSC Snow Leopard, where I have used the configuration the following option

./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

Then when I try this with my application I get the following error:

<Dario.Moricciani@Dario-Moriccianis-MacBook:~/Desktop> root

Take in mind that I have installed the latest version (1.6) of glew using MacPorts, see for example the configuration options above.

While if I use the root binary distribution it work fine … Please any one can help me ?

Best Regards

Can you, please, try to re-configure ROOT with --enable-builtint-glew (and without --with-glew-xxx), and recompile/relink it? Will it help?

I have configure and compile with this options :

It looks like build system ignored --enable-builtin-glew, it still uses the version from MacPorts.
I do not have a Mac at the moment (and I never used MacPorts).

What is the output of configure script, at the end of the line “Checking whether to build included GLEW”?

I am sorry I forgot last line of configure.log :

.

.
Checking whether to build included GLEW
Result: yes

Hi,

just try:

./configure

and have a look what configure manages to detect. On my machine I’ve:

Checking for GL/gl.h ... /usr/X11/include
Checking for libGL, or libMesaGL ... /usr/X11R6/lib
Checking for libGLU, or libMesaGLU ... /usr/X11R6/lib
Checking for GL/glew.h ... no
Checking for libGLEW ... no
Checking whether to build included GLEW ... yes
Checking for pkg-config ... /sw/bin/pkg-config
Checking for libftgl ... no
Checking whether to build included libftgl ... yes

Cheers, Fons.

ok but in order to compile root using GL and glew software installed by macport what I have to do ?

I have understand the problem ! If I load the built-in library all is OK :

Hello. I’m sorry, I did not answer you before since I hate guessing and do not have working Mac at the moment.
But still, what you have is not a solution. So, today I have to start guessing:
on Mac, do you have to specify something like DYLD_LIBRARY_PATH? What it can be (oh, guessing-shmessing started :frowning: ) is that libglew from MacPort is found before our built-in library is found and you have this problem
(I think, “mac-enabled” collegues will correct me, if I’m wrong).
Can you show what is your DYLD_LIBRARY_PATH?

Still, this does not explain the case you had at the beginning.
