I have a question: How to compile a static library in Linux with gcc, i.e. I need to compile my source code into a file named out.a. Is it sufficient to simply compile with the command gcc -o out.a out.c? I'm not quite familiar with gcc, hope anyone can give me a hand.

See Creating a shared and static library with the gnu compiler [gcc]

gcc -c -o out.o out.c

-c means to create an intermediary object file, rather than an executable.

ar rcs libout.a out.o

This creates the static library. r means to insert with replacement, c means to create a new archive, and s means to write an index. As always, see the man page for more info.

Creating a shared and static library with the gnu compiler (gcc), Here's a summary on how to create a shared and a static library with gcc. The goal is to show These examples were tested and run on Linux. Linux, in a way, is a series of static and dynamic libraries that depend on each other. For new users of Linux-based systems, the whole handling of libraries can be a mystery. But with experience, the massive amount of shared code built into the operating system can be an advantage when writing new applications.

Static and Dynamic Libraries, Create a C file that contains functions in your library. filter_none. Create a header file for the library. filter_none. Compile library files. gcc -c lib_mylib.c -o lib_mylib.o. Create static library. Now our static library is ready to use. $ gcc -static -static-libstdc++ -static-libgcc. Also note the library order. After building the program, check whether the program is statically linked as what we do for C programs: $ ldd cpp-program not a dynamic executable. Note for CMake: to specify a static library (libssl as an example) in CMake (find more here):

Generate the object files with gcc, then use ar to bundle them into a static library.

Static Libraries, Static libraries are simply a collection of ordinary object files; conventionally, Static libraries permit users to link to programs without having to recompile its� Everything works fine if you collect it from the dynamic link library: gcc test.c -lcurl -o test Now I want to raise a static program: gcc test.c /tmp/curl/lib/libcurl.a -static -lcurl -lssl -lcrypto -ldl -lm -lz -DCURL_STATICLIB -I/tmp/curl/include -o test He is going with errors:

How to Create and Use a C Static Library | by Lee Gaines, Static libraries, also called “archives”, are just collections of object files that contain functions. All the functions within the library are organized and� Creating a shared and static library with the gnu compiler (gcc) The tq84-library sources main.c Create the object files Create static library Link statically Create the shared library Link dynamically with the shared library Use the shared library with LD_LIBRARY_PATH Move the shared library to a

How to Use Linux's ar Command to Create Static Libraries, Use Linux's ar command to create function libraries when you're developing software. This tutorial will show you how to create a static library,� and the library rule as: libmylib.a: addSorted.o freeLinks.o ar rcu $@ $+ ranlib $@ the $+ here means "all of the dependency file names". Finally, if you want gcc to make an actual static executable, and not just use the library you made, you need to pass the '-static' option to gcc.

Linux Tutorial, How to generate a shared object: (Dynamically linked object library file.) Note that this is a two step process. Create object code; Create library; Optional: create � To compile it, use the following command (pass the static library testlib.a as the source file, so gcc compiler knows to link it later. 1 gcc -o test.out test.c testlib.a

  • check this
  • it would have helped to point out what the commands do, and what they intend to achieve. especially in this case the ar needs explanation, as it is the key to creating the static library.
  • The ar program creates, modifies, and extracts from archives, which are a single files holding a collection of other files in a structure that makes it possible to retrieve the original individual files. ar creates an index to the symbols defined in relocatable object modules in the archive when you specify the modifier s. (see man ar)
