I wouldn't recommend deleting static libraries because it is too easy to shoot
yourself in the foot if you do. If you only strip your binaries/libraries
then you can still develop, you just won't get very nice backtraces if Sage
crashes on you.
Note, even if you removed all static libraries (again, I wouldn't recommend
it!) you can still develop pure Python code which should constitute a fair
amount of the coding theory / graph theory code (I don't know though).
For your convenience lets reduce the size of 2.10.3.rc2:
We start with:
$ du -h --max-depth=1
3.3M ./examples
64K ./ipython
222M ./devel
27M ./doc
784M ./local
17M ./data
700K ./spkg
1.1G .
This is due to the fact that all the source SPKGs have already been replaced
by empty files. This is done automatically for binary releases.
Now we strip the shared libraries
$ cd $SAGE_ROOT
$ cd local/; find . -name "*.so" | xargs strip
$ cd ..
$ du -h --max-depth=1
3.3M ./examples
64K ./ipython
222M ./devel
27M ./doc
684M ./local
17M ./data
700K ./spkg
952M .
Now we strip executable (this is a bit messy):
$cd local; find . -perm /u+x -type f | xargs strip
$cd ..; du -h --max-depth=1
3.3M ./examples
64K ./ipython
222M ./devel
27M ./doc
648M ./local
17M ./data
700K ./spkg
915M .
At this point we still got a fully functional developer-enabled copy of Sage.
However, we are still at 915M.
We should consider removing _some_ of the static libraries, i.e. those which
are redundant.
$ cd local; find -name "*.a" | xargs rm
$ cd ..
$ du -h --max-depth=1
3.3M ./examples
64K ./ipython
220M ./devel
27M ./doc
383M ./local
17M ./data
700K ./spkg
650M .
However, now development might not be possible anymore.
