I was concerned to have to preform the configure/make every time I change the destination path. It turns out that the makefile produced by configure uses prefix only for the install. Thus it is not big deal anymore. Thx for all commnets. A. -- http://mail.python.org/mailman/listinfo/python-list

It's not clear that the build depends on the destination. The install does, though. The Makefile does the install, so it needs the prefix. config builds the makefile, so it also needs the prefix. Under M$ Windows I was able to install Python in let's say C:\Program Files\python and then move/copy it frelly to whatever location I need. Only thing was the resetting PATH to the new location. I miss that under Linux. Are you sure it doesn't work well enough for you to use on Linux? A quick grep on the python binary and library files reveal that only pydoc knows the prefix - and that points to files that don't exist on my system. That leaves five things to worry about: unix avoids making the user muck with the path by installing the binary in the path, so you have to move the binaries and the libraries separately. The pydoc executable uses the path to the python binary in it's #! line. If you use the shared binary, you may have to muck with the load library state information (not sure what to use to do this on your Linux). Third party libraries may break. Oh yeah - tracebacks on .pyc and .pyo files may be confused because the source files aren't where they where when the file was generated, but that should be the same as it is on Windows. mike -- Mike Meyer [EMAIL PROTECTED] http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information. -- http://mail.python.org/mailman/listinfo/python-list

Even if he reconfigures, he's not going to rebuild the whole thing unless he does a make clean. For example, I just built Python twice, once with a prefix of /usr/local/apps/pytest1 and then with a prefix of /usr/local/apps/pytest2 and timed the compile: BUILD 1: [EMAIL PROTECTED] 7:16AM Python-2.4.1 % cat compile_it.sh ./configure --prefix=/usr/local/apps/pytest1 make make install ./compile_it.sh 107.50s user 9.00s system 78% cpu 2:28.53 total BUILD 2: [EMAIL PROTECTED] 7:18AM Python-2.4.1 % cat compile_it.sh ./configure --prefix=/usr/local/apps/pytest2 make make install ./compile_it.sh 21.17s user 6.21s system 56% cpu 48.323 total I *know* a significant portion of the time of BUILD 2 was spent in configure. So if he's really eager to save a few CPU seconds, he can edit the Makefile manually and change the prefix section. Maybe I'm just a slow file editor, but I would do configure again just because it'd probably be faster for me. Not to mention potentially less error prone. But he's going to have to build something again. Or not. He *should* be able to just tar up the whole directory and it should just work. I moved /usr/local/apps/pytest1 to /usr/local/apps/pyfoo and imported xml.dom.minidom and it worked. I'm guessing the python binary searches relative to itself first (??). But if I move the python binary to a new location, it doesn't find xml.dom.minidom. JMJ -- http://mail.python.org/mailman/listinfo/python-list
Manging multiple Python installation
Hi, I run Mandrake 10.0 with python 2.3 installed by default. I want to keep it as it is but need another, very customized Python installation based of 2.3 as well. I would prefer to have it the way it is on Windows, one folder e.g. /opt/mypython with all the stuff under that. It would be unlike that standard installation where everything is scattered across /usr /bin/ /.../doc. That way I can easily tar it and distribute to whatever machine I want. How can I achieve that? Please help, Andy -- http://mail.python.org/mailman/listinfo/python-list
