Where Is C++ Std Library On Mac
Return value. Implementation-defined value. If command is a null pointer, returns a nonzero value if and only if the command processor exists. NoteOn POSIX systems, the return value can be decomposed using WEXITSTATUS and WSTOPSIG. This article is intended primarily for students leaning C for the first time on a Mac. It’s not a step-by-step tutorial on how to write and compile code in the applications described. 5 Ways to Write C Code on Your Mac. It’s hard to rank the various solutions by some standard. After you’ve read about them, it may well be that one is the obvious way to proceed initially.
About
makelib is a generic cross-platform makefile for building C/C++/Objective-C libraries.
Its purpose is to ease the build process of libraries for cross-platform projects.
Available targets by system
Building on OSX, the following files will be produced:
- Static library (
.a):i386x86_64armv7armv7sarm64 - Dynamic library (
.dylib):i386x86_64 - Mac framework (
.framework):i386x86_64
On Linux:
- Static library (
.a): host architecture - Dynamic library (
.so): host architecture
Note that on OS X builds, ARM libraries are obviously targeted for iOS.
Configuration
Recommended project structure
You may use makelib as a submodule of your project.
You'll need a build directory with a specific structure, a directory with sources, a directory with includes and finally a Makefile with configuration options.
Here's an example project structure:
Configuration Makefile
A makefile containing configuration values for makelib is required.
Assuming the previous project structure and a C++ project, this makefile may look like:
Please read the section below for details about each configuration value.
C++ Std String
Configuration values
PRODUCT
The name of your product/project.
PRODUCT_LIB
The name for the generated static library.
Note: always use a lib prefix.
PRODUCT_DYLIB
The name for the generated dynamic library.
Note: always use a lib prefix.
PRODUCT_FRAMEWORK
The name for the generated Mac framework package.
PREFIX_DYLIB
The directory in which the dynamic library is intended to be installed.
PREFIX_FRAMEWORK
The directory in which the Mac framework is intended to be installed.
DIR_INC
The directory with include files.
DIR_SRC
The directory with source files.
DIR_RES
The directory with resource files, link Info.plist.
DIR_TESTS
The directory with unit test files, if any.
EXT_C
The file extension for your C source files (typically .c).
EXT_CPP
The file extension for your C++ source files (typically .cpp).
EXT_M
The file extension for your Objective-C source files (typically .m).
EXT_MM
The file extension for your Objective-C++ source files (typically .mm).
EXT_H
The file extension for your header files (.h, .hpp, etc).
FILES
The project files to compile.
Note that you can use the GET_C_FILES function for convenience:
FILES_TESTS
The unit test files to compile.Note that you can use the GET_C_FILES function for convenience:
CC
The compiler to use (clang, gcc, g++, etc).
LIBS
Any libraries to link with when building the project.
Eg: -lpthread -lz -lc++How to view library on mac high sierra os.
FLAGS_OPTIM
Optimisation flags for the compiler (Os, O3, etc).
FLAGS_WARN
Warning flags for the compiler.
Eg: -Wall -Werror -Wpedantic
FLAGS_STD_C
The C language standard to use (c99, c11, etc).
FLAGS_STD_CPP
The C++ language standard to use (c++11, c++14, etc).
FLAGS_OTHER
Any other flags to pass to the compiler.
FLAGS_C
Specific flags for the C compiler.
FLAGS_CPP
Specific flags for the C++ compiler.
FLAGS_M
Specific flags for the Objective-C compiler.
FLAGS_MM
Specific flags for the Objective-C++ compiler.
Mac library folder. You can also sync them to iOS devices and view them on Apple TV. And if you want to use your own images as your desktop picture or screen saver, the images need to be in your System Photo Library before you can select them in System Preferences.If you have only one photo library, then it's the System Photo Library. Photos in your System Photo Library are available in apps like iMovie, Pages, and Keynote. You can use iCloud Photos, Shared Albums, and My Photo Stream only with the System Photo Library. If you choose a different library in Photos without designating it as the System Photo Library, the iCloud tab in Photos preferences is disabled:If you designate a new library as the System Photo Library and then turn on iCloud Photos, the photos and videos in the new library will merge with those already in your iCloud Photos.
BUILD_LEGACY_ARCHSBuilds legacy architectures (eg. i386 on macOS).
Note: define it before including Common.mk
