WebBy default, libtool uses PIC objects for shared libraries and non-PIC objects for static libraries. The --with-pic option also accepts a comma-separated list of package names. Specifying --with-pic= pkgs is the same as configuring every package in pkgs with --with-pic and every other package with the default configuration. WebMar 31, 2024 · The difference between static and shared libraries is how those are used, for instance by an executable. The code from a static library is directly integrated into the program: the compiler will take copies of the code the program uses from the static library and make it part of the program.

WebA shared library consists of an archive of object files (.ofiles) collected into one file by either the compiler or the linker. Usually, to create a shared library, the .ofiles must be compiled into Position Independent Code (PIC) by the compiler. WebDownload and use 600+ Chicago stock photos for free.

There is no code to relocate them in ld.so. There is no copy-on-write. Non-PIC shared libraries are almost always a performance loss, so there's no point in supporting them. This is especially true of x86-64 because it has better support for PIC than x86.

WebDec 10, 2024 · But there is a workaround in 3 steps: 1. Disable the libc support checking; 2. Output the relocatable file (.o) as native-image compiling result; 3. Statically link the .o file with GCC by yourself. We managed to do this with musl to statically link the output .o file with other static libraries (.a) into a shared library (.so) . WebA static convenience library contains non-PIC objects, so can be linked into an old static library, or a program. When GNU Automake is used, you should use noinst_LTLIBRARIES instead of lib_LTLIBRARIES for convenience libraries, so that the -rpath option is not passed when they are linked.

WebStep 2: Creating a shared library from an object file Now we need to actually turn this object file into a shared library. We will call it libfoo.so: gcc -shared -o libfoo.so foo.o Step 3: Linking with a shared library As you can see, that was actually pretty easy. We have a shared library. Let us compile our main.c and link it with libfoo. WebMay 10, 2011 · $ cat test.c static int foo = 100; int function (void) { return foo; } $ gcc -fPIC -shared -o libtest.so test.c So foo will be in data, at a fixed offset from the code in function, and all we need to do is find it! On amd64, this is quite easy, check the disassembly:

WebStatic libraries are archives of object files, and have file names like liblibrary.a. Some targets also support shared libraries, which typically have names like liblibrary.so. If both static and shared libraries are found, the linker gives preference to linking with the shared library unless the -staticoption is used.
