Solaris+root...

Hi,

So after too many Christmas parties I have managed to compile the
2.20/05 version from yesterday...

Here are all the steps I took to compile and install ROOT using
egcs-2.91.60 19981201 (egcs-1.1.1 release) on a Sparc-Station20
under SunOS 5.5.1 (i.e. the CMSWGS at CERN)

1. Create the root ROOT directory i.e. where you want to install everything

2. Download file root_v2.20.source.tar and unpack in this directory
this contains directories src/, cint/, test/ and tutorials/

3. Download file root_v2.20.SunOS.5.4.tar and upack in same directory
this contains directory root

4. mv src root/

5. Setup environment variables
cd root
setenv ROOTSYS $PWD
setenv PATH $(PATH):$ROOTSYS/bin
setenv LD_LIBRARY_PATH $(LD_LIBRARY_PATH):$ROOTSYS/lib
Make sure that no entries in the paths exist from previous
ROOT installations.

6. Change makefile
cd src
ln -s Makefile.solaris Makefile
now edit and change to use the following lines

# Makefile of ROOT for Solaris with egcs
PLATFORM = solaris
CXX = g++
CC = gcc
CXXFLAGS = -fPIC -fno-rtti -fno-exceptions -I/usr/openwin/include
CFLAGS = -fPIC -I/usr/openwin/include
CINTCXXFLAGS = -fPIC -DG__REGEXP1 -DG__UNIX -DG__OSFDLL \
-DG__SHAREDLIB -DG__ROOT -DG__REDIRECTIO
CINTCFLAGS = -fPIC -DG__REGEXP1 -DG__UNIX -DG__OSFDLL \
-DG__SHAREDLIB -DG__ROOT -DG__REDIRECTIO
OPT = -g
NOOPT =
LD = $(CXX)
LDFLAGS = $(OPT)
SOFLAGS = -shared
SOEXT = so
SYSLIBS = -lm -ldl
SYSXLIBS = -L/usr/openwin/lib -lX11 -lm -lgen -ldl -lsocket
XLIBS = $(ROOTSYS)/lib/libXpm.a -L/usr/openwin/lib -lX11 -lsunmath
CILIBS = -lm -ltermcap -ldl -L/usr/ccs/lib -lgen

##### MACROS and TARGETS #####

include Make-macros

##### DEPENDENCIES #####

include Make-depend

# end of Makefile

I am not sure whether the -fno-rtti and -fno-exceptions options are
completely neccessary... but they were used in the Linux-egcs makefile
which I used as a template.

7. The following files need changing in directory $ROOTSYS/src
UNIX_UnixSystem.cxx
ROOTX_rootx.cxx

In file UNIX_UnixSystem.cxx go to line 398
and change the lines

#if defined(R__SOLARIS) && !defined(R__I386) && !defined(__SunOS_5_6)
sigact.sa_handler = (void (*)())SIG_IGN;

To the following:

#if defined(R__SOLARIS) && !defined(R__I386) && !defined(__SunOS_5_6)
sigact.sa_handler = (void (*)(int))SIG_IGN;

Do the same for the lines around 1777 also.
Change:

#if defined(R__SOLARIS) && !defined(R__I386) && !defined(__SunOS_5_6)
sigact.sa_handler = (void (*)())sighandler;

To:

#if defined(R__SOLARIS) && !defined(R__I386) && !defined(__SunOS_5_6)
sigact.sa_handler = (void (*)(int))sighandler;

The process is similar for ROOTX_rootx.cxx...

>From line 269:
Change:

#if defined(__sun) && !defined(__i386) && !defined(__SunOS_5_6)
ignore.sa_handler = (void (*)())SIG_IGN;

To:

#if defined(__sun) && !defined(__i386) && !defined(__SunOS_5_6)
ignore.sa_handler = (void (*)(int))SIG_IGN;

>From line 281:

Change:

#if defined(__sun) && !defined(__i386) && !defined(__SunOS_5_6)
handle.sa_handler = (void (*)())SigUsr1;

To:

#if defined(__sun) && !defined(__i386) && !defined(__SunOS_5_6)
handle.sa_handler = (void (*)(int))SigUsr1;

7.5 If you want the TTF stuff.... download this now and unpack it in the $ROOTSYS directory

8. Make sure you are in the $ROOTSYS/src directory and do
gmake clean

9. followed by
gmake

10. Go and have a cup of tea...

Maybe it would be nicer to modify the source files UNIX_UnixSystem.cxx and
ROOTX_rootx.cxx to somehow pick up automatically the SunOS version?
One might assume that __SunOS_5_5 might be defined automatically somewhere
but this does not appear to be the case on the installation I am using
on the CMSWGS at CERN... I guess you could just put something in the
makefile?

NB I have not yet tried to compile the utilities h2root g2root etc

Cheers,

Jon.
