Open ios/YourAppName.xcodeproj in Xcode Right-click on Your App Name in the Project Navigator on the left, and click New File… Create a single empty Swift file to the project (make sure that Your App Name target is selected when adding) when Xcode asks, press Create Bridging Header and do not remove Swift file then. re-run … Read more
Before iOS8, Xcode only allowed the option of creating static libraries for iOS. The common problem with that was we had to ship the binary and headers separately. Later, some developers came with the idea of creating ‘static frameworks’. [the .framework is just a folder with symbolic links to the lib and the headers]. One … Read more
Let’s see what’s going on, try $ du -hs A 13M A $ file A A: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.27, not stripped $ ldd A linux-vdso.so.1 => (0x00007fff1b9ff000) libXrandr.so.2 => /usr/lib/libXrandr.so.2 (0x00007fb21f418000) libX11.so.6 => /usr/lib/libX11.so.6 (0x00007fb21f0d9000) libGLU.so.1 => /usr/lib/libGLU.so.1 (0x00007fb21ee6d000) libGL.so.1 => /usr/lib/libGL.so.1 … Read more
Remove static keyword in method definition. Keep it just in your class definition. static keyword placed in .cpp file means that a certain function has a static linkage, ie. it is accessible only from other functions in the same file.
There are (in most cases, discounting interpreted code) two stages in getting from source code (what you write) to executable code (what you run). The first is compilation which turns source code into object modules. The second, linking, is what combines object modules together to form an executable. The distinction is made for, among other … Read more
Dynamic linking can reduce total resource consumption (if more than one process shares the same library (including the version in “the same”, of course)). I believe this is the argument that drives its presence in most environments. Here “resources” include disk space, RAM, and cache space. Of course, if your dynamic linker is insufficiently flexible … Read more
Static libraries increase the size of the code in your binary. They’re always loaded and whatever version of the code you compiled with is the version of the code that will run. Dynamic libraries are stored and versioned separately. It’s possible for a version of the dynamic library to be loaded that wasn’t the original … Read more
