how do I know what's the dependencies of a qt application ?

when I try  build a QT app to an arch package, how do I know what's the dependencies of a qt application ?

such as VLC, https://archlinux.org/packages/extra-st … 86_64/vlc/ ,  it shows that this app  needs  qt5-base \ qt5-svg  \ qt5-x11extras,

how do I know that my app needs which dependencies ?

I know that I can let my app link to its own standalone libs, but reuse is good.

any one who have the experience ?

pacman -Si <package>

Pacman/Rosetta for a list of common pacman commands.

He's trying to write a pkgbuild for a given binary, not query the stats of an existing package.

"Knowledge", "Experience", looking closely at the binary.
https://wiki.archlinux.org/title/PKGBUILD#Dependencies
Mainly looks at the makefile (qmake .pro or cmakelist etc) for the build requirements and also "ldd /path/to/binary" to see the linked objects and query their paths w/ "pacman -Qo"
You can use fine-libdeps for that, https://wiki.archlinux.org/title/Arch_p … pendencies

Ps: "Qt" - "QT" is "QuickTime"

I resort to building it in a clean chroot and adding dependencies as they are found to the PKGBUILD until it works.
