Hi,
I'm using rrd to make simple graphics (no perl, no ruby, no python, just
like the first example in the Alex van den Bogaerdt's tutorial) successfuly
in PowerPC/Linux, but now I'm facing troubles to reduce the total size of
(libpng+lifreetype+libart+librrd).
I tried:
-strip-unneeded;
-static/dynamic libs use;
-disable of python, ruby, perl;
I have a 769 kb executable file... can I do something else?
Thanks.
