Also note that when a library is examined, an object file within it can be left out of the link if it does not provide symbols that the symbol table needs. This is a very important feature of static linking. The C library I mentioned before makes a heavy use of this feature, by most...
compiling C/C++ code that is dependent on external libraries. I've been using the language for a while but only the extend of the standard library. The process is much different from in C than it is in languages like Python where there is a package manager for you to install external ...
$+ is like ‘$^’, but prerequisites listed more than once are duplicated in the order they were listed in the makefile. This is primarily useful for use in linking commands where it is meaningful to repeat library file names in a particular order....
grpc (and abseil) were installed using vcpkg and gcc 13 and I've had no problems building my projects with either clang 17 or gcc 13, but not so with clang 18+ I can see differences in generated symbols between clang 17 and 18, there's missing "U absl::lts_20240116::log_internal:...
In internal linking mode, add an extra "gcc -Wl,-r" phase to collect all the per-package _all.o files into a single "_allall.o" file, and pass -lgcc, -lmingw32, etc. at that time. Then perform internal linking as normal using the one "_allall.o" file instead of every indivi...

I installed the gcc version again and now the gcc examples work. I think it might be that I needed a different version of the omp library that I must have installed in the mean time. For example, using the gcc library the sample_csr2m now works: ...
The above output indicates that the main executable depends on three libraries. The second line in the above output is ‘libc.so.6’ (standard ‘C” library). This is how gcc linker is able to resolve the function call to printf(). ...

library in memory can be shared by different running processes. To build a shared library libvector.so : $: gcc -shared -fpic -o libvector.so addvec.c multvec.c Once we have created the library,we would then link: $: gcc -o prog21 main2.c ./libvector.so ...
