Just type the following command on Linux terminal. Command: gcc -v Output Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/5/lto-wrapper Target: x86_64-linux-gnu ...................... ......................
Compile 32-bit program on 64-bit gcc in C and C++ Nowadays the compiler comes with default 64-bit version. Sometimes we need to compile and execute a code into some 32bit system. In that time, we have to use thisS feature. At first, we Shave to check the current target version of the gcc compiler.
The -m32 flag tells GCC to compile in 32-bit mode.
DIFFERENCE BETWEEN g++ & gccg++ is used to compile C++ program. gcc is used to compile C program.
If you have a multilib GCC installed, it's as simple as adding -m64 to the commandline. The compiler should complain if it is not built with multilib support.
In order to link, you'll need all the 64-bit counterparts of the standard libraries. If your distro has a multilib GCC, these should also be in the repositories.
