ROOT 6.14.04 install error

Hello,

I am trying to install ROOT 6.14.04 on a computing cluster and I am getting the following error during the build:

I configure ROOT by doing:

cmake -Dbuiltin_afterimage=ON -Dbuiltin_fftw3=ON -Dbuiltin_cfitsio=ON …/root-6.14.04

_ROOT Version: 6.14.04
_Platform: Red Hat Enterprise Linux Server release 6.4 (Santiago)
_Compiler: gcc (GCC) 6.3.0

I think I am missing libpng but I am not sure. If that is the case then I will have to ask the administrators to install it for me. Is that actually the case? If not then how should I resolve this error?

Maybe your problem is not that you don’t have libpng, but that the version available is too old, as RHEL 6 is quite old itself. Is the compiler you are using from devtoolset? If yes, then building ROOT with it is not supported as far as I remember, due to ROOT-6207. If your cluster has CVMFS, I would recommend to pick ROOT from there if you can.

The compiIer was not from devtoolset and the cluster did not have CVMFS. I was able to install ROOT after having the administrators install libpng for me. ROOT was still picking up the old library so I had to force to just look at the new library by doing:

make -Dbuiltin_afterimage=ON -Dbuiltin_fftw3=ON -Dbuiltin_cfitsio=ON -DPNG_LIBRARY_RELEASE:FILEPATH=/panfs/pfs.local/software/install/libpng/1.6.35/gcc/6.3/lib/libpng.so …/root-6.14.04

Now its working though!
