What is the difference between g and gcc

Question

What is the difference between g   and gcc   Which one of them should be used for general c   development

User · Answer

I was testing gcc and g   in a linux system  By using MAKEFILE  I can define the compliler used by  GNU make   I tested with the so called  dynamic memory  locating feature of  C plus plus  by    int main     int   myptr   new int    myptr   1  printf  myptr 0  is  i n   myptr   return 0      Only g   can successfully compile on my computer while gcc will report error  undefined reference to  operator new unsigned long     So my own conclusion is gcc does not fully support  C plus plus   It seems that choosing g   for C   source files is a better option

gcc and g   are compiler-drivers of the GNU Compiler Collection  which was once upon a time just the GNU C Compiler    Even though they automatically determine which backends  cc1 cc1plus      to call depending on the file-type  unless overridden with -x language  they have some differences   The probably most important difference in their defaults is which libraries they link against automatically   According to GCC s online documentation link options and how g   is invoked  g   is equivalent to gcc -xc   -lstdc   -shared-libgcc  the 1st is a compiler option  the 2nd two are linker options   This can be checked by running both with the -v option  it displays the backend toolchain commands being run

For c   you should use g     It s the same compiler  e g  the GNU compiler collection   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

Although the gcc and g   commands do very similar things  g   is designed to be the command you d invoke to compile a C   program  it s intended to automatically do the right thing   Behind the scenes  they re really the same program   As I understand  both decide whether to compile a program as C or as C   based on the filename extension   Both are capable of linking against the C   standard library  but only g   does this by default   So if you have a program written in C   that doesn t happen to need to link against the standard library  gcc will happen to do the right thing  but then  so would g     So there s really no reason not to use g   for general C   development

GCC    is a common shorthand term for the GNU Compiler Collection  This is both the most general name for the compiler  and the name used when the emphasis is on compiling C programs  as the abbreviation formerly stood for    GNU C Compiler       When referring to C   compilation  it is usual to call the compiler    G       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   You could read more here
