How do I create a so file?
There are four steps:
- Compile C++ library code to object file (using g++)
- Create shared library file (. SO) using gcc –shared.
- Compile the C++ code using the header library file using the shared library (using g++)
- Set LD_LIBRARY_PATH.
- Run the executable (using a. out)
- Step 1: Compile C code to object file.
What is so file in Linux?
so file is a “shared object”, or library file containing compiled code that can be linked to a program at run-time. It is the Linux equivalent of a Windows DLL (dynamic link library).
How do you use a .so file in Linux?
You should use the linker option -rpath , which tells the linker to add information in the executable program where to find runtime libraries like your . so file. This will pass -rpath=$(pwd) to the linker, and $(pwd) causes the shell to call the pwd command to return the current directory.
How do I read a .so file?
However, you might be able to read the SO file as a text file by opening it in a text editor like Leafpad, gedit, KWrite, or Geany if you’re on Linux, or Notepad++ on Windows.
What is Dlopen in Linux?
dlopen() The function dlopen() loads the dynamic shared object (shared library) file named by the null-terminated string filename and returns an opaque “handle” for the loaded object. … If filename contains a slash (“/”), then it is interpreted as a (relative or absolute) pathname.
What is Ldconfig in Linux?
ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld. … ldconfig checks the header and filenames of the libraries it encounters when determining which versions should have their links updated.
Does Linux have dlls?
Do DLL files work on Linux? dll file (dynamic link library) is written for the Windows environment, and wont run natively under Linux. You would probably have to extract it and recompile it as an. so – and unless it was originality compiled with Mono, it is unlikely to work.
How do I open a shared library in Linux?
Once you’ve created a shared library, you’ll want to install it. The simple approach is simply to copy the library into one of the standard directories (e.g., /usr/lib) and run ldconfig(8). Finally, when you compile your programs, you’ll need to tell the linker about any static and shared libraries that you’re using.
What is lib a file?
Libaries consist of a set of related functions to perform a common task; for example, the standard C library, ‘libc. a’, is automatically linked into your programs by the “gcc” compiler and can be found at /usr/lib/libc. … a: static, traditional libraries. Applications link to these libraries of object code.
