here is my PKGBUILD file :-

    pwd
    cd ${pkgdir}
    find ${pkgdir}/ -name *.so -exec chmod 777 {} ;
    chmod 755 ${pkgdir}/usr/bin/*
}

what should I do ? I know this question suites more on arch forum but since we can ask about bash and shell scripting , So ..

Answer

Arch Linux implemented the UsrMerge in 2013 and since then it is required that Arch Linux packages use the libdir “/usr/lib” and sbindir “/usr/bin”. If you do not, then the files you try to install will conflict with the symlinks on disk, which pacman does not allow.

You will need to fix the directory locations in your package() function.

As you can see, this really has nothing to do with bash scripting, and everything to do with the nature of pacman’s packaging format and policies. 🙂
