Arch Linux

(apologies for format, my first report here)

Description:
hdf5 installs 6 pkgconfig files (currently), many of which have a Requires: field to list pkgconfig dependencies. They are given in this format, e.g. from /usr/lib/pkgconfig/hdf5_cpp.pc :

Requires: hdf5-1.12.2

which is wrong because there is no package called 'hdf5-1.12.2' installed; rather, there is a package called 'hdf5' installed with version '1.12.2'. The correct notation is using '>=', as found in e.g. /usr/lib/fontconfig/fontconfig.pc (from fontconfig-2:2.14.1-2):

Requires: freetype2 >= 21.0.15

Because of the wrong notation, queries on most of the hdf5 pkgconfig packages fail, e.g.

$ pkg-config --cflags hdf5_cpp
Package hdf5-1.12.2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `hdf5-1.12.2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'hdf5-1.12.2', required by 'hdf5_cpp', not found

I'm reporting this here because it seems Arch already does a wild dance to get some pkgconfig files in the first place: https://github.com/archlinux/svntogit-community/blob/0e8e99e35d87469c10928d63bd009bcb2c60418b/trunk/PKGBUILD


Additional info:
* hdf5 1.12.2-1

Steps to reproduce:
Perform any pkgconfig query, such as --modversion, on hdf5_cpp, hdf5_fortran, hdf5_hl, hdf5_hl_cpp or hdf5_hl_fortran.
