Requirements

Please make sure to follow the instructions for compiling python prior to building ROOT since ROOT needs to be built against python. ROOT may also be built against MySQL on the linuxes. Also note that often the version of the source we utilize for ROOT is Fermi-specific where patches have been applied or the version of ROOT is from a branch from their Subversion repository.

v5.20.00-gl5

...

We
...
ran
...
into
...
a
...
problem
...
this
...
time
...
with
...
distribution
...
of
...
our
...
linux
...
build
...
for
...
ROOT.
...
It
...
seems
...
prefix
...
cannot
...
be
...
used,
...
so
...
we
...
must
...
set
...
the
...
ROOTSYS
...
env
...
var
...
for
...
our
...
build.
...
make
...
install
...
no
...
longer
...
seems
...
to
...
work
...
unless
...
prefix
...
is
...
used,
...
so
...
we
...
are
...
left
...
to
...
prune
...
the
...
resulting
...
ROOT
...
build
...
directories
...
on
...
our
...
own.

Both

the

the

using:

otool

-L
...
name.dylib.
...
i.e.
...
otool -L
...
libCint.dylib
...
Next
...
update

the

using

the

command:
...

install_name_tool
...
-id
...
newID fileName i.e.
...
install_name_tool
...
-id
...
libCint.dylib
...
libCint.dylib
...
For
...
any
...
ROOT
...
libraries
...
referenced
...
do:
...

install_name_tool
...
-change
...
oldName
