“gcc” and “cint” installation manual

1. C++ compiler installation (30 min to 2 hours)

   • Unpack the tar-file (# tar xzvf gcc-3.2.tar.gz)
     Directory 'gcc-3.2' is created.

2. Make a new directory (# mkdir ObjectDir)

3. Descend in the directory you've created (# cd ObjectDir)

4. Type '../gcc-3.2/configure'

5. Type 'make bootstrap' (and wait a lot...)

6. Type 'make install' (as SuperUser) (and wait a little bit...

7. Modify your enviroment variables:
   # export PATH=/usr/local/bin:$PATH
   # export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

8. Check gcc version (# gcc -v)
   Output should be:
   Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.2/specs
   Configured with: ../gcc-3.2/configure
   Thread model: posix
   gcc version 3.2

9. CINT installation (20 min to 1 hour):

   • Unpack the tar-file (#tar xzvf cint.tar.gz)
     Directory 'cint' is created.

10. Compile Cint and optional library
    (#./setup platform/[machine])
    NOTE: you have to select the correct machine taking in account the gcc-compiler version!

11. If you have already unpacked 'root':
    copy the file 'long.dll' in $ROOTSYS/cint/include/
    (#cp include/long.dll $ROOTSYS/cint/include/.)
    root must be recompiled.
