Linking issues for Netx

bressan · September 18, 2019, 6:59am

I’m upgrading from root 6.16 to 6.18 and while doing that I stumbled in a compilation issue.
This started with conflicts with external XROOTD (from /cvmfs/sft.cern.ch/lcg/releases/xrootd/4.9.0-8e2008/x86_64-centos7-gcc63-opt) which I tried to overcome using internal.
root source is from git and branch is 6.18.00-rc1. Options are defined by

cmake3 -Dcxx14=ON -Dpythia6=ON -Dpythia8=ON -DCMAKE_INSTALL_PREFIX=$PWD/../root_v6.18.00_gcc6.3.1-opt $PWD/../root_v6.18.00 -DGDML=ON -Dgdml:BOOL=ON -DCMAKE_CXX_FLAGS='-fPIC -O2' -Dminuit2=ON -Dsoversion=ON -Drpath=ON -Dgl=OFF -DCMAKE-BUILD-TYPE=Optimized -Dbuildin-xrootd=ON

here is the linking log:

As a final comment, I don’t have the same problem on my local centos7 installation, where I’m
using the same compiler but from devtoolsets and not from
/cvmfs/sft.cern.ch/lcg/releases/gcc/6.3.0/x86_64-centos7/

ROOT Version: 6.18.00-rc1 (git branch)
Platform: lxplus (centos7)
Compiler: gcc 6.3.1

Can you try please to use latest ROOT release 6.18.04? In 6.18.04, builtin version of XrootD was upgraded to 4.10.0.

bressan · September 18, 2019, 9:01am

I’m switching to branch 6.18.04, and starting the configuration.

I noticed that even if I have -Dbuildin-xrootd=ON in the config cmake is looking for it in the system.
Is this correct?

– Found Xrootd version num: 4.9.1 (setting -DROOTXRDVERS=400090001)
– libXrdMain not found: xproofd will be a wrapper around xrootd
– include_dirs: /usr/include/xrootd;/afs/cern.ch/compass/scratch/monthly/d01_del1/bressan/roots/root_v6.18.04/proof/xrdinc
– libraries: /usr/lib64/libXrdUtils.so;/usr/lib64/libXrdClient.so;/usr/lib64/libXrdCl.so

oshadura · September 18, 2019, 11:42am

it should be:

-Dbuiltin_xrootd=ON

Can you double check please?

bressan · September 18, 2019, 11:53am

Doubled checked, it was incorrect. It may be that.
I’ll restart the compilation and let you know,

bressan · September 24, 2019, 2:31pm

After correcting everything is working fine.
