[arch-general] Is it a bug ? (device-mapper PKGBUILD)
Hi , I was looking at the device-mapper PKGBUILD . I'm not sure but the last line looks problematic : # fix device-mapper link bug ln -sf /lib/libdevmapper.so "${pkgdir}/usr/lib/libdevmapper.so" || return 1 What If device-mapper is not yet installed in the system ? What am I missing ?

if i understand it correctly, build() just builds the package. only when you pacman -U it will you execute those commands (in sequence). therefore, the make and install steps are exectuted before the symlink is created. -- patrick brisbin

There will be a symlink in /usr/lib/libdevmapper.so that links to /lib/libdevmapper.so, whether this file exists or not. When the package is installed, this file exists because it is included inside the package.

aha . Lesson of the day : We can link non-existing files . Thank you for the clarification .
