Can you install GCC 10 on a Raspberry Pi?
In this article I will show you how to install GCC 10 on your Raspberry Pi system and how to compile C++17 programs. At the time of this writing Raspbian is based on Debian Buster, which comes with the stable but slightly outdated GCC 8.3 as the default C and C++ compiler.
Where can I get cross compiler for Raspberry Pi?
The cross compiler is built on the Linux system on which we want to compile our Raspberry Pi programs. Download the build shell script from github and place into a newly created empty directory that we’ll use for downloading and building everything.
Which is the default compiler for the Raspberry Pi?
The above procedure will keep GCC 8.3 as the default C and C++ compiler for any package that depends on it. If you want to compile C programs you could use gcc-9.1 and for C++ g++-9.1.
Where can I download a build script for Raspberry Pi?
Download the build shell script from github and place into a newly created empty directory that we’ll use for downloading and building everything. Open the script and change some variables according to the information gathered from the Raspberry Pi system.
Which is the correct flags to use when compiling C code on a Raspberry Pi?
gcc takes the -mcpu= (or -march=) flags to produce optimized code for a particular CPU type. There’s a plethora of arm variants, and the gcc Arm target also provides numerous FPU types. Which -mcpu=/-march= flags and -mfpu= flags are the proper/native ones to use when compiling C code on a Raspberry Pi ?
How to compile C files on Raspberry Pi?

How to compile C + + 17 on Raspberry Pi?
To compile a C++17 that uses an ‘If block’ and an ‘init statement’ use the following steps: In order to save the code, you need to create a file and name it if_test.cpp. When that is said and done, you should see something like this on your Raspberry Pi:
