static-libraries

问题 I need little clarification in this area. I feel that the terms Static library & Dynamic Library are not correct. lib1.o + lib2.o + lib3.o --> "LinkerOutputFile"(executable or library). If this "LinkerOutputFile" contains the code of all the files lib1.o , lib2.o, lib3.o then its said that "LinkerOutputFile" is satically-linked "LinkerOutputFile"(executable or library). (or) If "LinkerOutputFile" just contains references & other information about to lib1.o, lib2.o, lib3.o without containing

问题 I have a project where I have one static library libhelper.a and another with my actual shared object library, libtestlib.so . My goal is to link libhelper.a into libtestlib.so . Is that possible on Linux/BSD? When I tried and created a test program I got the following errors: ./prog1:/usr/local/lib/libtestlib.so.1.0: undefined symbol '' My guess is that this is occurring because libhelper.a was not compiled with -fPIC while libtestlib.so was. What is the proper way to build programs that use

问题 I've done a some looking around but most of the answers I've found have been or felt incomplete and have left me a little confused. I have been given a C Library that I need to compile into a static library using XCode 4.3 and then use in a separate iOS app project, but I'm unsure about how to proceed. I'm not sure if the directory structure matters or not, but here it is anyways: Library -> Section1 -> src -> .c files -> sec1 -> .h files -> sec1.h -> Section2 -> src -> .c files -> sec2 -> .h

问题 I have a problem with linking my mixed language framework to a project. 1) I create framework with Swift and Objective-C classes. 2) Main logic was stored in Swift file. For example the class with method that calls NSLog("Swift log was called"). 3) Objective-C file has class that has method in which I create an instance of Swift class and call Swift-log method. 4) I link this framework with my Objective-C project, I can call all what I need in this project, but when I want to build this

问题 I've created my lib.a file with several gcc -c file.c -o file.o then ar sr lib/libtest.a file1.o file2.o file3.o confirmed with ar -t lib/libtest.a file1.o file2.o file3.o but when I try to compile test aplication gcc lib/libtest.a test.c -o test I got undefined reference in function main : to used function from file1.o, file2.o, file3.o 回答1: Order matters with libraries - try: gcc test.c -o test lib/libtest.a Basically, the linker reads the library when it comes across it on the list of

问题 My problem is simple: I would like to use the error function Erfc(double) in Java with Eclipse but I do not want to implement it (because it is complicated). So, I have found this: http://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/special/Erf.html That does exactly what I want. The problem is that I can not use it. As it is not from "docs.oracle.com", I can not just import it. But unfortunately, I can not include the library and use it neither because what I

问题 The title is pretty self explanatory: I need to call functions (they are extern "C" so no mangling) in a Visual Studio 2019 .lib file from a mingw-w64 .exe ; I have the source code for both. The reason is that I'm writing a 3D game with 2 renderers: OpenGL and Direct3D 11, and the core code and the OpenGL renderer are compiled with mingw-w64, but the D3D11 part is compiled with VS. How to interoperate between them? Can I merge both renderers into one .a (mingw-w64) static library or one .dll

问题 I've a linux application that links against a static library (.a) and that library uses the dlopen function to load dynamic libraries (.so) If I compile the static library as dynamic and link it to the application, the dlopen it will work as expected, but if I use it as described above it won't. Can't a static library uses the dlopen function to load shared libraries? Thanks. 回答1: There should be no problem with what you're trying to do: app.c: #include "staticlib.h" #include "stdio.h" int

问题 I'm trying to link a Static Library to a node.js addon in windows. I used Visual Studio 2013 Express to create a .lib library and I link it in the binding.gyp file as follows: { "targets": [ { "target_name": "modbus", "sources": [ "modbus.cc" ], "include_dirs": [ "<!(node -e \"require('nan')\")", "lib/libmodbus/src" ], "libraries": [ "-l<(module_root_dir)/lib/libmodbus/src/win32/modbus.lib" ] } ] } When I run node-gyp rebuild I recieve errors like: modbus.obj : error LNK2001: external symbol
