Question about libarchive

[PoloNX]

HI @WinterMute Thanks for the help about libarchive I'm new with pacman packages I use xrepo normally. When i try to build with 3.7.2 I have the following error about the link :

Maybe you have to add the switch-libzstd in depends() ?

[WinterMute]

Adding libzstd to depends won't make any difference, you still need to link the library. The easiest way to deal with this is to use pkg-config to find the libs that need linking like this

LIBS :=     -lstdc++fs `$(PREFIX)pkg-config --libs libarchive libcurl`

You'll also need to update packages again using pacman -Syu to pick up the libarchive package that I fixed again.

Thanks!
