Hi, I'm trying to strip perl down as much as possible for a small |
| 2 |
embedded server. The end app will just run server type applications |
| 3 |
(and possibly a perl based web application for configuration). All |
| 4 |
modules needed will be bundled in the build so I have removed CPAN, |
| 5 |
debugger, headers, etc |
| 6 |
|
| 7 |
Another design point is that I have decided that I don't need to support |
| 8 |
locale's other than the main english, unicode (and unicode european |
| 9 |
languages). |
| 10 |
|
| 11 |
OK, so this is my INSTALL_MASK to install perl (ignore the line breaks) |
| 12 |
|
| 13 |
export INSTALL_MASK="${INSTALL_MASK} */usr/lib/perl5/*.h |
| 14 |
usr/lib/perl5/5.*/ExtUtils/ |
| 15 |
usr/lib/perl5/5.*/CPAN/ |
| 16 |
usr/lib/perl5/5.*/CPANPLUS/ |
| 17 |
usr/lib/perl5/5.*/*-linux-*/auto/Encode/JP |
| 18 |
usr/lib/perl5/5.*/*-linux-*/auto/Encode/KR |
| 19 |
usr/lib/perl5/5.*/*-linux-*/auto/Encode/CN |
| 20 |
usr/lib/perl5/5.*/*-linux-*/auto/Encode/TW |
| 21 |
usr/lib/perl5/5.*/*-linux-*/Devel/ |
| 22 |
usr/lib/perl5/5.*/*-linux-*/auto/Devel/ |
| 23 |
usr/lib/perl5/5.*/Module/CoreList.pm |
| 24 |
usr/lib/perl5/5.*/Module/Build* |
| 25 |
usr/lib/perl5/5.*/perl5db.pl usr/lib |
| 26 |
/perl5/5.*/[Pp]od |
| 27 |
usr/lib/perl5/5.*/unicore/mktables |
| 28 |
usr/lib/perl5/5.*/unicore/TestProp.pl |
| 29 |
*/usr/lib/perl5/5.*/unicore/*.txt |
| 30 |
*/usr/lib/perl5/*.pod" |
| 31 |
|
| 32 |
Afterwards I then strip a huge bunch of comments out of some perl files: |
| 33 |
sed -i -e 's/^#.*//' -e '/^$/d' \ |
| 34 |
${TARGET}/usr/lib/perl5/5.12.2/unicore/lib/*/*.pl |
| 35 |
|
| 36 |
|
| 37 |
Now that gets me down to some 20-30MB install size, but the squashfs |
| 38 |
size of the same is around 4MB (vs around 10-12MB normal). |
| 39 |
|
| 40 |
The main size reduction from here is reducing the unicode file sizes. I |
| 41 |
have had a quick hack at this above by eliminating some of the |
| 42 |
JP/KR/CN/TW stuff, but there is still some 10s MB that could be removed. |
| 43 |
I think the solution is to understand how mktables works and customise |
| 44 |
it so that it generates only the required lookup tables? Anyone got any |
| 45 |
experience or solutions? |
| 46 |
|
| 47 |
Any other ideas on shrinking the install further? (I'm a bit reluctant |
| 48 |
to strip too many core modules at this stage until the final build is |
| 49 |
decided - also most only consume a few KBs...) |
| 50 |

Thanks |
