I have this implemented in apk-tools. Take a look there how it can be implemented and feel free to reuse the code if possible. http://apk-tools.sourceforge.net (use svn version.

Its relatively easy to automatically find out the dependencies. find [ all elf files ] | while read elffile ; do for so in `readelf -d $elffile |\ grep NEEDED |\ sed 's/.*Shared library: //; s/\[\(.*\)\]/\1/'` ; do dep=`find_lrp_that_has_file $so` add_dependency $dep done done So you shouldn't need to figure out all dependencies by hand. -- Natanael Copa ------------------------------------------------------------------------- Using Tomcat but need to do more?
