MAC OS GDB TUTORIAL INSTALL

You can install 'MinGW-W64' under 'Cygwin' by selecting these packages (under 'devel' category): The MinGW-W64 (a fork of MinGW, available at ) supports target of both 32-bit and 64-bit native Windows. MinGW-W64 Target 32/64-bit Native Windows This is because Cygwin is a Unix emulator under Windows. However, if the target is Cygwin, to distribute, you need to distribute Cygwin runtime environment ( cygwin1.dll).

MAC OS GDB TUTORIAL CODE

If the target is native Windows, the code can be distributed and run under Windows.

If you use Cygwin's GCC, the target could be native Windows or Cygwin.

64-bit compilers may produce target of 32-bit or 64-bit.

32-bit compilers/programs can run on 32-bit or 64-bit (backward compatible) Windows, but 64-bit compiler can only run on 64-bit Windows.

Windows/Intel uses these instruction sets: x86 is a 32-bit instruction set i868 is a 32-bit enhanced version of x86 x86_64 (or amd64) is a 64-bit instruction set.To differentiate these variations, you need to understand the followings: MinGW-W64: a fork of MinGW that supports both 32-bit and 64-bit windows.It also included MSYS (Minimal System), which is basically a Bourne shell ( bash ). MinGW: MinGW (Minimalist GNU for Windows) is a port of the GNU Compiler Collection (GCC) and GNU Binutils for use in Windows.It also included the commonly-used Bash shell. Cygwin is huge and includes most of the Unix tools and utilities. Cygwin GCC: Cygwin is a Unix-like environment and command-line interface for Microsoft Windows.Thread model: posix Installing GCC on WindowsДЇor Windows, you could either install Cygwin GCC, MinGW GCC or MinGW-W64 GCC. If gcc is not installed, the system will prompt you to install gcc. Open a Terminal, and enter ' gcc -version'. It is the standard compiler for most Unix-like operating systems. GNU Toolchain, including GCC, is included in all Unixes. -std=c++2a, or -std=gnu++2a (C++2a with GNU extensions), experimental.-std=c++17, or -std=gnu++17 (C++17 with GNU extensions), experimental.-std=c++14, or -std=gnu++14 (C++14 with GNU extensions), default mode for GCC 6.1 and above.You can use command-line flag -std to explicitly specify the C++ standard. The default mode is C++98 for GCC versions prior to 6.1, and C++14 for GCC 6.1 and above. GCC version 3 (2001): incorporating ECGS (Experimental GNU Compiler System), with improve optimization.

GCC version 1 (1987): Initial version that support C.

GCC is also a cross-compiler, for producing executables on different platform. They are also ported to Windows (by Cygwin, MinGW and MinGW-W64). GCC (and GNU Toolchain) is currently available on all Unixes.

MAC OS GDB TUTORIAL PORTABLE

GCC is portable and run in many operating platforms.

MAC OS GDB TUTORIAL GENERATOR

GNU Bison: a parser generator (similar to lex and yacc).

GNU Autotools: A build system including Autoconf, Autoheader, Automake and Libtool.

GNU Binutils: a suite of binary utility tools, including linker and assembler.

GNU Make: an automation tool for compiling and building applications.

GNU Compiler Collection (GCC): a compiler suite that supports many languages, such as C/C++ and Objective-C/C++.

GCC is a key component of so-called ' GNU Toolchain', for developing applications and writing operating systems. The current version is GCC 7.3, released on. It is now referred to as ' GNU Compiler Collection'. GCC, formerly for ' GNU C Compiler', has grown over times to support many languages such as C ( gcc), C++ ( g++), Objective-C, Objective-C++, Java ( gcj), Fortran ( gfortran), Ada ( gnat), Go ( gccgo), OpenMP, Cilk Plus, and OpenAcc.

Richard Stallman founded the GNU project in 1984 to create a complete Unix-like operating system as free software, to promote freedom and cooperation among computer users and programmers.
