How to find which package provides a file?

Question

For example, I can't install package qcad because of error: "can't find qdict.h".
How can I find the package which provides the file qdict.h so I can install the package qcad?

@Joe, I illustrate: I want to install qcad, but it doesn't compile because can't find file qdict.h. I want to know which package contains that file. I've tried to google, but found nothing. — Eddy_Em, Mar 28 '13 at 07:45
I've download ebuild, made some error fixes in code and rebuild manifest. QCad is absent in official repos. — Eddy_Em, Mar 28 '13 at 07:55
@warl0ck, there's no package qt. BTW QCad needs qt3, but there's no qt3 in official packages. I don't understand how it's possible. — Eddy_Em, Mar 28 '13 at 07:56
Thanks to all! I found app-portage/pfl: its e-file helps me. This is qt-meta. — Eddy_Em, Mar 28 '13 at 08:09

You may use the e-file command from the pfl package (emerge -av app-portage/pfl) to search by package contents.

e-file YOURFILE

Alternatively, you may use an online database.

Regarding the qcad package specifically, you probably need the Qt4 package. IIRC, use emerge -av x11-libs/qt-gui (If that doesn't work out, try searching for QT packages. Use this query: emerge -s qt.)

To be more precise, pfl provides the command e-file – Tobias Kienzler Nov 05 '13 at 11:04

FYI, the e-file command simply queries the very same online database linked in the answer. It's called the Portage File List. – daveloyall Jan 16 '20 at 23:26
