What is an SO 6?
so. 6 is a symbolic link to the 64-bit x86 C library, used to run 64-bit executables; /usr/lib/x86_64-linux-gnu/libc.so is (usually) a linker script pointing to the 64-bit C library (dynamic or shared, as needed) and dynamic linker, and is used to link 64-bit executables (when building them).
What is rpath and rpath link?
The difference between -rpath and -rpath-link is that directories specified by -rpath options are included in the executable and used at runtime, whereas the -rpath-link option is only effective at link time. On SunOS, if the -rpath option was not used, search any directories specified using -L options.
Can Mac use .so files?

What can I do with a linker command line?
Any other ideas that are on the same complexity level as a simple linker command line (like creating a simple linker script etc.) are welcome too, as long as they are not weird hacks like editing the resulting binary…
How to link a symver to a c file?
I think you can get away with making a simple C file containing the symver statement and perhaps a dummy function calling memcpy. Then you just have to ensure that the resulting object file is the first file given to linker. I suggest you either link memcpy () statically; or find the source of memcpy ( ) and compile it as your own library.
How to link against older version of glibc?
Using gcc and ld on x86_64 linux I need to link against a newer version of a library (glibc 2.14) but the executable needs to run on a system with an older version (2.5).
