ROOT

Hi,

I am trying to install root version v5-21-01-alice in macbook.
I am getting following error:

net/netx/src/TXNetFile.cxx:61:37: error: XrdOuc/XrdOucPthread.hh: No such file or directory
make: *** [net/netx/src/TXNetFile.o] Error 1

Could anyone please suggest some possible solution?

Thanks in advance

You are compiling ROOT with an inconsistent version of xrootd. You are wrongly taken an obsolete version in /opt/alien.
See with the Alice librarian.
