Now in order to compile with 32-bit gcc, just add a flag -m32 in the command line of compiling the ‘C’ language program. Hence the fourth line Target: x86_64-linux-gnu confirms that we are running 64-bit gcc.
Just type the following command on Linux terminal.ĬOLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/5/lto-wrapper
Therefore we must have a knowledge about this.īefore proceeding forward, let’s confirm which bit-version of gcc is currently installed in our system. But it would lead to problem, if someone wants to run their program as a 32-bit rather than 64-bit for testing or debugging purposes. Well it would be a good option in terms of speed purposes. Mostly compiler(gcc or clang) of C and C++, nowadays come with default 64-bit version.
