Windows: local printer option is greyed out

admin — Wed, 16 Mar 2011 12:17:36 +0000

Some time ago I need to add the local printer to the system, however, this option was greyed out in the “Add printer” wizard.
The problem was caused by local policy, preventing the adding of the new devices to the system.

The following should be done to enable “Add local printer” option

Start the policy editor (Control Panel -> Administrative tools -> Local security policy)
Select “Local policy” item
Find the item “Devices: Prevent Users from Installing Printer Drivers” in the section Security Settings -> Security Options and change it to Enabled
Go to “Security Settings -> User Rights Assignment” section and check, that “Load & Unalod Drivers” option contains the active user group. It important, that even if it has “All Staff” already, it still could miss “Administrators” group, so it’s necessary to add it manually.

Oracle: problem relinking binaries on Solaris

I’ve got the following message relinking the binaries on Solaris:

ld: fatal: dlopen() of support library (libmakestate.so.1) failed with error:

ld.so.1: /usr/ccs/bin/sparcv9/ld: fatal: /usr/lib/libmakestate.so.1: wrong ELF class: ELFCLASS32

The problem was caused by missing 64-bit library libmakestate.so.1 in /usr/lib.

The normal library should look like the following:

[#] file /usr/lib/sparcv9/libmakestate.so.1
libmakestate.so.1: ELF 64-bit MSB dynamic lib SPARCV9 Version 1, dynamically linked, not stripped

If the library does not exist or is incorrect, it should be reinstalled from the package SUNWsprox ( Sun WorkShop Bundled 64-bit make library)

This command checks, if the package is installed in the system:
[#] pkginfo -i SUNWsprox

After installing the package relink works fine.
