Installing Python 2.5.1 (built against tcltk 8.4) for Linux

Download Python

1. Download Python 2.5.1 from

• Create a directory such as rh9_gcc32 (or cd into the directory corresponding to OS and gcc version for which you want to install python, such as rhel4_gcc34 )

2. Edit the file, "Setup," in the "Modules" directory, "Modules/Setup"
   • Enable zlib (Uncomment the line corresponding to "zlib")
   • To build Python against tcltck 8.4, there are three lines to edit in the file (I would suggest searching for "_tkinter" in the Modules/Setup file, then following the documentation)
     1. Enable tkinter, by Uncommenting the line "

Do a Standard Build 

• Run
  1. make
  2. make install

Do Custom Build Python against an arbitrary version of tcl/tk

After running 'configure,' in the same directory, there will be a file created in the Modules directory, named "Setup:" Modules/Setup. 

1. Edit the file, "Modules/Setup"
   • There will be 4 relevant lines in this file that you have to edit.  They look like this:
   • # *** Always uncomment this (leave the leading underscore in!)*:
      _{*}
     1. _tkinter _tkinter.c tkappinit.c -DWITH_APPINIT
     {color}

2. Run
   • make
   • make install

* Step 3 must be done before 4.   Running, "./configure," generates the file Modules/Setup 

While running "make", if you run into any problems finding tcl8.4 or tk8.4 libraries, try setting the environment variable, LD_RUN_PATH

...

to point to the location of the

...

tcltk libraries:
make clean
setenv LD_RUN_PATH <Location of tcltk libraries>
make
make install
unsetenv LD_RUN_PATH 

Installing Python 2.5.1 (built against tcltk 8.4) for Windows

By default, tcl/tk version 8.4 ships with Python 2.5.1 for Windows so just go through the installation process.

1. Download the appropriate python2.5.1 msi file for your windows architecture http://www.python.org/download/releases/2.5.1/
2. Using command.exe, enter the following command
   • if installing on a network drive
     • msiexec /a <python-msi-path>/python-2.5.1.msi ALLUSERS=1 TARGETDIR=<installation director
   • Example, to install python in "V:\Glast_Software\Toaster\GLAST_EXT\Windows-i386-32bit\python\2.5.1-gl1\vcc71" logged in on glast06, enter
<Library Location>*
• e.g., setenv LD_RUN_PATH/usr/lib
3. Run make
   • make
4. ** Unset the LD_RUN_PATH environment varible{*}
   • unsetenv LD_RUN_PATH
5. Run
   • make install
     •  msiexec /a V:\Glast_Software\Toaster\GLAST_EXT\VC8\python\python-2.5.1.msi ALLUSERS=1 TARGETDIR="V:\Glast_Software\Toaster\GLAST_EXT\Windows-i386-32bit\python\2.5.1-gl1\vcc71"
