programmable GCC?
|
| |
Just wondering: could someone tell me
whether any useful subsets of GCC's
functionality, such as its conversion
from intermediate code to the assembly
language of one of GCC's vast array
of output architectures, or its
advanced code optimisation capabilities,
have been separated into an independent... more »

enabling "set but unused" warning
|
| |
I've seen numerous posts regarding disabling the "set but unused" warning message. I'm having the opposite problem; I can't get this warning to occur. Given the simple program

How to I deference symbolic links when linking?

symlinks a_lib.so.1 pointing to it, and a_lib.so pointing to a_lib.so.1,
just as they ought to be. I am compiling a program which compiles against
a_lib.so. How do I get the linker to link with a_lib.so.1.1 instead?... more »
