Libarpack++.so is missing in arpack++

Support AUR

libarpack.so is present in arpack (from community repo) but there isn’t a library for arpack++. Can I copy the library “libarpack.so” from arpack to the folder where arpack++ is installed? So this way I just need to change his name and this wont happen:

-- Found Arpack++ lib: ARPACKPP_LIB-NOTFOUND

pkgfile libarpack++.so shows there is not package actually using this library
How can I make libraries given hearder files (.h)?

Can I use the arpack++ library from Debian/Ubuntu repositories?

You need to install arpack++ from AUR. arpack and arpack++ are different libraries.

After I installed arpack++ from AUR I copied the missing files (.so and .a files) from ubuntu repo (I got them using a container) into a path /usr/lib

Im not sure it will work

Looks like arpack++ does not contain a library by default. There is also arpackpp in the AUR, it matches the Debian version, but it provides just the headers. If you compile a application, this should be enough.

You might want to check what source the Debian project uses and try to compile it yourself.
