Does the order of static libraries matter?

Does the order of static libraries matter?

When linking object files (static libraries) into an executable, the order in which you give the libraries matters. For simple scenarios where there are no cyclic references, the dependent library should come on the left, and the library which provides said dependency should come on the right.

Why does the order in which libraries are linked sometimes cause errors in gcc?

Why does the order in which libraries are linked sometimes cause errors in GCC? Basically this kind of errors are originated from the linker in the compilation phase. Otherwise it can be solved by ordering the libraries correctly. Loaders and tsort these two can help to rearrange and correct the ordering.

What is Rdynamic?

-rdynamic. Pass the flag -export-dynamic to the ELF linker, on targets that support it. This instructs the linker to add all symbols, not only used ones, to the dynamic symbol table. This option is needed for some uses of dlopen or to allow obtaining backtraces from within a program. -s.

Does gcc include linker?

The gcc (or g++ ) command is simply a driver. It runs other programs, including the compiler proper ( cc1 for C code, cc1plus for C++ code) and the assembler and the linker.

What is library order?

Nov 12, 2019 1985. “On Order” is part of the process of the library acquiring (purchasing) a book. It means that we’ve made the decision to get it, and sent an order to the publisher, but it has not arrived yet. When a book does arrive, its status changes to “Received” with a date of when it came in.

What is no as needed?

Including it says your program doesn’t need any of the API definitions: -no-as-needed says, whatever they are, you’re getting them all anyway.

What is — whole archive?

–whole-archive. For each archive mentioned on the command line after the –whole-archive option, include every object file in the archive in the link, rather than searching the archive for the required object files.

What is rpath in GCC?

In computing, rpath designates the run-time search path hard-coded in an executable file or library. Dynamic linking loaders use the rpath to find required libraries. Specifically, it encodes a path to shared libraries into the header of an executable (or another shared library).

Is gcc a compiler or linker?

The GNU Compiler Collection (gcc) The GNU Compiler Collection, gcc, can compile programs written in C, C++, Java and several other languages. It provides many useful command line options and syntax extensions, and also serves as a powerful frontend for the GNU linker, ld.

Where does gcc look for libs?

Note: gcc looks for the libraries’ names from left to right and stop finding when it matches the first library with the searching term. You also can show the library search directories list by adding the verbose flag -v when linking.
