- 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)
- 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
- 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
- gcc - What are my available march mtune options? - Stack Overflow
Is there a way to get gcc to output the available -march=arch options? I'm getting build errors (tried -march=x86_64) and I don't know what my options are The compiler I'm using is a proprietary wrapper around gcc that doesn't seem to like -march=skylake The flags should be the same so I assume whatever options I'd send to gcc to dump
- 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)
- What is the difference between clang (and LLVM) and gcc g++?
GCC is a big bag of software The typical process, as I understand it, is for a GCC frontend to lex and parse the code, convert to GCC's internal Register Transfer Language (RTL), and then for a backend to write out native code So one typical flow is: C code ---> GCC's C frontend ---> RTL ---> GCC's x86 backend ---> x86 machine code
- What is the purpose of using -pedantic in the GCC G++ compiler?
However, in some cases, the C and C++ standards specify that certain extensions are forbidden Conforming compilers such as GCC or g++ must issue a diagnostic when these extensions are encountered For example, the GCC compiler’s -pedantic option causes GCC to issue warnings in such cases
