static-libraries

I use code::blocks to compile my static library. The output result is a libstatic.a file. Now, how do I link to my library to use functions that were compiled? (I tried to use #include "libstatic.a" but my project doesn't compile) cc -o yourprog yourprog.c -lstatic or cc -o yourprog yourprog.c libstatic.a You should #include "libstatic.h" , i.e. use the appropriate header file in your code ( that's why your code doesn't compile) and include the path to your libstatic.a in the linker options as one of your input libraries. This webpage has some examples on linking to a static library, e.g. gcc

I'm trying to make a static library from a class but when trying to use it, I always get errors with undefined references on anything. The way I proceeded was creating the object file like g++ -c myClass.cpp -o myClass.o and then packing it with ar rcs myClass.lib myClass.o There is something I'm obviously missing generally with this. I bet it's something with symbols. Thanks for any advice, I know it's most probably something I could find out if reading some tutorial so sorry if bothering with stupid stuff again :) edit: myClass.h: class myClass{ public: myClass(); void function(); }; myClass

I am building a static library. The build setting has the Architectures set to: $(ARCHS_STANDARD) which is shown as Standard Architectures (armv7, armv7s, arm64) I build the lib choosing iOS Device AND then using the simulator (for example iPhone Retina). Now that I have two builds (one inside Debug-iphoneos and the other inside Debug-iphonesimulator , I use lipo -create to create the aggregated lib: lipo -create path/to/first/lib /path/to/second/lib -o MyLib.a If I used this library in another project to simulate on any iOS device with 64-bit architecture, it gives symbol(s) not found for

I know an .so file is a kind of dynamic library (lots of threads can share such libraries so there is no need to have more than one copy of it in memory). But what is the difference between .a and .la ? Are these all static libraries? If dynamic libs have big advantages over static ones, why there are still lots of static libraries? I also want to know the underlying mechanism to load libraries (both kinds) and how a piece of code in a lib is invoked when it is used somewhere. Which part of the kernel should I study? And what related Linux command/utility should I know in order to know how a

I know very little about DLL's and LIB's other than that they contain vital code required for a program to run properly - libraries. But why do compilers generate them at all? Wouldn't it be easier to just include all the code in a single executable? And what's the difference between DLL's and LIB's? Charles E. Grant There are static libraries (LIB) and dynamic libraries (DLL). Libraries are used because you may have code that you want to use in many programs. For example if you write a function that counts the number of characters in a string, that function will be useful in lots of programs.
