Compiling ROOT: Undefined reference to `pthread_atfork'

ROOT
1

Hello,

I have tried to compile root on debian (testing amd64) and I have the following error:

[i]…/root_v5.30.01.source/configure --prefix=/usr/local/root_v5.30.01 --enable-minuit2 --enable-mathmore --enable-roofit --enable-x11 --enable-opengl --with-x11-libdir=/usr/lib/x86_64-linux-gnu --with-xft-libdir=/usr/lib/x86_64-linux-gnu --with-xext-libdir=/usr/lib/x86_64-linux-gnu

…

…/…/lib/libXrdClient.a(XrdClientEnv.o): In function Initializer': /home/ode/built-sources/root_v5.30.01.built/net/xrootd/src/xrootd/src/XrdClient/XrdClientEnv.cc:225: undefined reference topthread_atfork’[/i]

I have found a similar bug reported for Ubuntu but it didn’t help: https://savannah.cern.ch/bugs/?82494.

Can you help me please?

Best regards,

I have found the problem. A simple link to the library -lpthread was missing for creation of different binaries:

In ./net/xrootd/src/xrootd/src/XrdClient/GNUmakefile:
