Hi all,
I am trying to install on my laptop root version 4.04/02. I downloaded the source file from:
root.cern.ch/root/Version404.html
then following the instructions in $ROOTSYS/README/INSTALL I did:
(I am using Debian sid, kernel 2.6.16, gcc 3.3)
pwd
/usr/local
cp ~/root_v4.04.02.source.tar.gz .
tar -zxvf root_v4.04.02.source.tar.gz
cd root
echo $ROOTSYS
/usr/local/root
#./configure linuxdeb
…
make
…

make[1]: Leaving directory `/usr/local/root/xrootd/src/xrootd’
make: *** [xrootd/src/xrootd/lib/libXrdSec.so] Error 2
I took a look at the file:
./xrootd/src/xrootd/src/XrdXrootd/XrdXrootdProtocol.hh
and on line number 63 I added:
class XrdXrootdAioReq;
trying to recompile I got next error:
g++ -O1 -o bin/g2root main/src/g2root.o
-lpacklib -lkernlib
-lg2c -lnsl -lm -ldl -pthread -rdynamic

collect2: ld returned 1 exit status
make: *** [bin/g2root] Error 1
now, the root is already there and working, but what sre these errors, and how can the later be resolved?
Cheers,
Ivan
