GCC    
The {GNU} {Compiler} Collection, which
currently contains front ends for {C}, {C}, {Objective-C},
{Fortran}, {Java}, and {Ada}, as well as libraries for these
languages (libstdc, libgcj, etc).

GCC formerly meant the GNU {C} compiler, which is a very high
quality, very portable compiler for {C}, {C} and {Objective
C}.

The compiler supports multiple {front-ends} and multiple
{back-ends} by translating first into {Register Transfer
Language} and from there into {assembly code} for the target
architecture.

{(http://gcc.gnu.org/)}.
{Bug Reports (http://gcc.gnu.org/bugzilla/)}.
{FTP} gcc-2.X.X.tar.gz from your nearest {GNU archive site}.
{MS-DOS (ftp://oak.oakland.edu/pub/msdos/djgpp/)}.

Mailing lists: gcc-help@gcc.gnu.org, gcc-announce@gcc.gnu.org
(announcements).

["Using and Porting GNU CC", R.M. Stallman, 1992-12-16].

英文字典中文字典相关资料:


  • What is the difference between g++ and gcc? - Stack Overflow
    GCC or G++ just choose a different front-end with different default options In a nutshell: if you use g++ the frontend will tell the linker that you may want to link with the C++ standard libraries The gcc frontend won't do that (also it could link with them if you pass the right command line options)
  • What is the difference between GNU, GCC, and MinGW?
    GCC stands for "GNU Compiler Collection" and is a piece of GNU software that includes a compiler with frontends for multiple languages: The standard compiler releases since 4 6 include front ends for C (gcc), C++ (g++), Objective-C, Objective-C++, Fortran (gfortran), Java (gcj), Ada (GNAT), and Go (gccgo)
  • Compiler standards support (c++11, c++14, c++17) - Stack Overflow
    Instead you can check the online docs at gcc Standards and the useful synopsis at cppreference com According to cppreference, full support of c++11 came with gcc 4 8 1; To have full support of c++14 (with some of the new features of c++17), instead, you need gcc 5 0 and above
  • Whats the meaning of gcc -c and gcc -o? [duplicate]
    -c tells GCC to compile a source file into a o object file Without that option, it'll default to compiling and linking the code into a complete executable program, which only works if you give it all your c files at the same time To compile files individually so they can be linked later, you need -c
  • c++ - GCC: Difference between -O3 and -Os - Stack Overflow
    GCC -O3 is more likely to be helpful than in the past, and bloat problems are probably less bad GCC used to enable -funroll-loops as part of -O3, but doesn't anymore (only with -fprofile-use with PGO data available) Upcoming GCC 12 changes -O2 to include -ftree-vectorize (SIMD) like clang -O2 does; previously it used to only be enabled at -O3
  • GCC -g vs. -g3 GDB flag: What is the difference?
    The broader answer is that gcc supports four levels of debug information, from -g0 (debug information disabled) through -g3 (maximum debug information) Specifying -g is equivalent to -g2 Curiously, the gcc docs say little about what information -g -g2 includes or excludes: Request debugging information and also use level to specify how much
  • How to install GCC piece by piece with GMP, MPFR, MPC, ELF, without . . .
    No, the bootstrapping does not depend on it It makes sense to use --disable-shared for building GMP, MPFR and MPC but not for GCC itself (and using the download_prerequisites script means you don't need to build GMP, MPFR and MPC manually anyway)
  • Does GCC support C++20 std::format? - Stack Overflow
    GCC 13 has added support for std::format According to cppreference, as of GCC 13, no gaps remain in its C++20 support (in both the core language and the standard library) This bugzilla ticket notes that some C++23 extensions to std::format have not yet been implemented GCC 13 can be expected around April 2023
  • gcc - Determining C executable name - Stack Overflow
    gcc main c -o myCoolExecutable o This is ok if your program consists of a single file If you have more files I suggest using make: create a Makefile and then run the command make A Makefile is a file containing some rules for compilation An example can be the following (# means the line is a comment): CXX = gcc #CXXFLAGS = -std=c++11 #INC
  • gcc is not recognized - How to make gcc mingw work in Windows?
    The Mingw binary installation instructions (such as these) tells me to change the PATH environment variable in Windows, in order to use the gcc g++ etc commands anywhere This might also be necessary for some programming IDE to find the compiler
