Hi Experts,
I am new user using RPM libraries and C programming APIs for my project.
I am using rpmlib 5.1.6. but I am not getting any proper documentation
on this. Whatever document I can get by googling are of the version 4 of
RPMlib and most of them are out-dated. I mean the functions/APIs and
headers file (like dbindex.h, header.h etc) mentioned over there are no
longer existing!!
My action items will be mainly:
1) Fresh Install.
2) Upgrade.
3) Downgrade.
4) Uninstall.
5) Abort of any actions.
6) To get the action status of any ongoing actions.
7) To get all package information. Identify what are they..??
8) Signature of the packages.
9) Package dependencies.
10) Search package by attributes (like name, version)
11) Checksum of a package.
12) Pre/post-install handling.
13) RPM DB connections:
a) To list all the installed packages.
b) To list downgradable packages
c) To list non-downgradable packages
d) List of the packages in sub-tree
e) To get all package information.
I have checked rpm.org and prm5.org documentations but no help from
those...By googling, I have found some APIs (from rpmlib version 4) such
as :
1) int rpmReadPackageInfo(int fd,
Header * signatures,
Header * hdr);
2) int rpmInstallPackage(char * rootdir,
rpmdb db,
int fd,
char * prefix,
int flags,
rpmNotifyFunction notify,
char * labelFormat,
char * netsharedPath);
but there are no longer supported in v5.1.6.
When I tried to compile a cpp file with the following command:
g++ -I/usr/include/rpm package-info.cpp -L/MM_BASE/host-tools/lib/rpm/
-L/usr/lib/rpm -lrpmbuild -lrpm -lrpmdb -lrpmio
/usr/bin/ld: cannot find -lrpmbuild
collect2: ld returned 1 exit status
Please help me out. Please let me know which APIs I should concentrate
for the above tasks.
Thanks and Regards,
Sanjay
