makepkg only handles libprovides/libdepends correctly if the naming scheme is: lib${name}.so --> lib$name.so.$ver But it is not uncommon for libname.so to link to a '.so' file that does not follow this naming scheme. For example, these 2 schemes are sometimes used: lib$name.so --> libname$major.$major.$minor lib$name.so --> libname-$major.$major.$minor There exists other schemes. With those cases, and before these patches, makepkg would add lib$name.so to provides unversioned and display a warning. And if another package adds lib$name.so as a dependency, the build will succeed and only a warning will be displayed. Not only makepkg fails to find version/arch for libraries in those scenarios. But the success of builds in both provide/depend sides might give the illusion that versioned sodepends are actually honored. If the idea behind these 2 patches is rejected. I would like to propose promoting the warning in find_libprovides() to an error.
