SPARC. The placement of new libraries and programs follows the standard conventions described in 32-bit and 64-bit Libraries. The 32-bit libraries continue to be located in the same place, while the 64-bit libraries should be placed in the specific architecture-dependent directory under the normal default directories. Placement of 32-bit and 64-bit specific applications should be transparent to the user.
This means that 32-bit libraries should be placed in the same library directories. 64-bit libraries should be placed in the sparcv9 subdirectory under the appropriate lib directory.
Programs that require versions specific to 32-bit or 64-bit environments are a slightly different case. These should be placed in the appropriate sparcv7 or sparcv9 subdirectory of the directory where they are normally located.
64-bit libraries should be placed in the amd64 subdirectory under the appropriate lib directory.
Programs that require versions specific to 32-bit or 64-bit environments should be placed in the appropriate i86 or amd64 subdirectory of the directory where they are normally located.
