Installed or upgraded Ubuntu 20.04 Focal Fossa Requirements, Conventions or Software Version Used Software Requirements and Conventions Used Software Requirements and Linux Command Line Conventions Category How to Compile basic C program from source code.This will be achieved by using the apt install command. The objective of this tutorial is to install GCC the C compiler on Ubuntu 20.04 LTS Focal Fossa Linux. It is a standard compiler used in most projects related to GNU and Linux, for example, Linux kernel. For instance, to compile a file of geek.c through Linux terminal, you must write the following command with -m32 flag.GCC, the GNU Compiler Collection is a compiler system developed to support various programming languages.

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.
