zypper list/dump to find files in a package

English Install/Boot/Login

I have a problem compiling a package and the problem is that it can not find interpolation.h. I know it should be part of alglib and I think I had installed the development package earlier.

First I tried the straight way:

> find / -xdev -name interpolation.h
(nothing)

Then found zypper has a file-list option, so:

> sudo zypper se --file-list interpolation.h

i+ | hugin               | Toolchain for Stitching of Images and Creating Panoramas | package

I am quite sure the alglib-interp-devel has interpolation.h but I like to see details, a full path would be nice.

No file information and this is the most detail I could find in zypper, interesting enough you can not find the work “dump” in the zypper man pages of the --help output

I know I can somehow get the .rpm file for alglib-interp-devel and then use “rpm -qlp” and will do that but zypper does somehow know “interpolation.h” is installed but I can not find any details about/around it.

Is there any way to access the internals of zypper / libzypp to dump this information?

Huh? You already has this package installed, you can simply do “rpm -ql alglib-interp-devel”.

zypper does somehow know “interpolation.h” is installed

Yes, it can search file list of installed packages. Same as using “rpm -ql”.

Okay, that work!

And yes, will never forget from now on, but missed that point that zypper is just a layer over the RPM package manager.

Good to see the details as it explains why the make script can not find interpolation.h:

> rpm -ql alglib-interp-devel | grep interpolation.h
/usr/include/alglib/polynomial/polinterpolation.h
/usr/include/alglib/rational/polinterpolation.h
/usr/include/alglib/rational/ratinterpolation.h
