No it wont, unfortunately. rpm 3.*, rpm 4.0.* and rpm >= 4.1 have quite distinct API's, from 4.1 upwards fortunately the API has remained almost unchanged. > > Also, is there any such application written in C which I can refer > for the usage of the rpmlib APIs.

Check out apt-rpm >= 0.5.15cnc3 (http://moin.conectiva.com.br/AptRpm), it supports all major versions from 3.0.x to 4.2.1 using the rpmlib API and written in C++ (which, while not exactly C should be close enough for you to figure out the API usage and especially the differences between rpm versions). Or better yet, grab the repository head from https://oops.kerneljanitors.org/repos/apt-rpm/trunk/ (it's a subversion repository), it now has generic rpm version detection making supporting several versions much nicer than what it was. Oh and the stuff you're interested in lives in apt-pkg/rpm/ directory :) - Panu - _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/rpm-list
