Why does Apple only allow for Static Frameworks on iOS?
Clearly Apple has the ability to create dynamically loaded libraries (known as frameworks) for iOS, as they ship several with XCode (such as UIKit). App developers only have the ability to create static libraries, or at best, trick Xcode into…

Why are there two different kinds of linking, i.e. static and dynamic?
I've been bitten for the n-th time now by a library mismatch between a build and deployment environment. The build environment had libruby.so.2.0 and the deployment environment had libruby.a. One ruby was built with RVM, the other was built with…

In the current project I'm working on, some of the C# classes are being stored as source code in SQL Server database records, and executed as needed using CSScript. This is being done so that the server doesn't have to be taken down to replace the…

I am making a renderer as a hobby, one thing I thought to try is making the low levelAPI be dynamically swappable, i.e. you could have an opengl or vulkan backend and switch between the two without needing to recompile or even relaunch the…

Dynamically load user code from a common library
My project aims to provide a common interface between multiple different HDL simulators, so users can write test benches that will work no matter the simulator used. In this situation, it is the simulator, not the user's code, that is the driving…

How do .so files avoid problems associated with passing header-only templates like MS dll files have?
Based on the discussion around this question. I'd like to know how .so files/the ELF format/the gcc toolchain avoid problems passing classes defined purely in header files (like the std library). According to Jan in that answer, the dynamic…

What should developers know about Windows executable binary file compression?
I'd never heard of this before, so shame on me, but programs like UPX can compress my files by 80% which is totally sweet, but I have no idea what the the disadvantages are in doing this. Or even what the compressor does.

Why use dynamic linking for less-popular libraries?
I know the difference between static and dynamic linking. I know why the notion of a library is important. And I even know why you'd want to link something like OpenGL, platform-specific APIs, or OpenSSL dynamically; lots of applications use them…

Could Java import C++ classes from a library using JNA or JNI?
In past, I used JNI to access some winapi functions, however winapi is C and therefore just procedural. Now my plan is different and I need to know whether I'm going in the right direction. What I want is:
to make a dynamic C++ OOP library for…

If a dynamic library exports the address to a global variable defined within the library, how are accesses to that variable translated during dynamic linking so that a running application can interact with it?
