"If you only installed c compiler you would have command gcc but not command g++;g++ is c++ compiler not c compiler"

"So running the gcc command automatically includes the c standard libraries running g++ automatically includes the c++ standard libraries etc;but notice running gcc does not automatically link in the c++ standard library"

"Also if you use g++ to link the object files it automatically;links in the std c++ libraries gcc does not do this"

"So using g++ is better than gcc"

"G++ seems to work better than gcc in my experience"

"Use g++ not gcc;gcc is a c compiler whereas g++ is a c++ compiler"

"G++ compiler is more strict then gcc compiler"

"Use g++ to compile c++ programs it ll link in the standard c++ library;gcc will not"

"Unfortunately g++ packed the structs significantly looser than gcc which caused significant problems sharing objects between c and c++ code"

"Btw you should use g++ not gcc when compiling c++ code;there are significant differences even if gcc is sometimes able to compile c++ or fortran code you ll mostly use gcc to compile c code"

"C++ source files should be compiled by g++ not by gcc;remember that gcc means gnu compiler collection and also contains gfortran and gccgo etc."

"Mex is just a tool which calls one underneath and since g++ is the c++ compiler of gcc you should install this one;as far as i know it will still not work because matlab supports only gcc 4.3 not sure about that"

I have some issues with compiling very simple code with gcc or g++ main.c below

The g++ version is a little larger than the gcc version but not 100x larger

So maybe the answer is that it s c++ code and the fact they compiled the objects with gcc not g++ made you think it was c code;if they only link with g++ then adding preprocessor checks and extern c is useless that only affects preprocessing and compilation at the linking stage that s already done

Some distributions chop you might need to more than just gcc package devtools into tons of small packages gcc g++ binutils gdb

Since there is only one compiler it is also accurate to call it gcc no matter what the language context;however the term g++ is more useful when the emphasis is on compiling c++ programs

I also need the .cpp to be compiled with g++ and related cxxflags whereas the .c need to be compiled with gcc and simplier cflags

The -wall option asks for almost all warnings the -wextra ask for some more of i strongly recommend compiling with gcc -wall -wextra -g for c code or g++ -wall -wextra -g for c++ code also add other useful options such and the -g option is asking for debug information in dwarf format these days

With this test code gcc produces a diagnostic only for the unsigned member;so although i d also usually prefer unsigned integers for bitfields or for bitwise manipulation g++ is happier and quieter with int here

Using g++ to compile multiple .cpp and .h files in sublime 2;the reason why using .cpp in sublime text fails is gcc does not do

The reason for this is gcc essentially says use c rules when driving the tool chain and g++ says use c++ rules when driving the tool chain;g++ knows that to create a working executable it needs to pass -lstdc++ to the linker stage whereas gcc obviously doesn t think this is necessary even though it knew to use the c++ compiler at the compile the source code stage because of the .cc file ending

If gcc g++ are not installed then you need to install them via homebrew;cmake setup in the cmake settings make sure that both the c and c++ cuda host compilers are set to your install of gcc g++ usually in usr local bin

A more up-to-date g++ gets a more up-to-date g++ right compiling with with usr libexec gcc i686-redhat-linux 4.8.3 cc1plus via g++ -c tst.cpp we get

Also use the correct gcc frontend executable g++ will treat .c files like c++ files unless you explicitly tell it not too;so if you are compiling real c then use gcc not g++

This is also reproducible with gcc not just g++
