Using GCC

After Jupiter is installed with Ubuntu, Bianbu systems, it supports onboard development. Here, we take the use of GCC to compile a test program as an example to introduce the onboard development method.

Install GCC

Ubuntu Desktop and Bianbu Desktop versions have gcc installed by default. You can view the version of gcc by running the following command:

milkv@k1:~$ gcc -v
Using built-in specs.
Target: riscv64-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 13.2.0-4ubuntu3-bb2' --with-bugurl=file:///usr/share/doc/gcc-13/README.Bugs --enable-languages=c,ada,c++,go,d,fortran,objc,obj-c++,m2 --prefix=/usr --with-gcc-major-version-only --program-suffix=-13 --program-prefix=riscv64-linux-gnu- --enable-shared --enable-linker-build-id --libexecdir=/usr/libexec --without-included-gettext --enable-threads=posix --libdir=/usr/lib --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --with-default-libstdcxx-abi=new --enable-gnu-unique-object --disable-libitm --disable-libquadmath --disable-libquadmath-support --enable-plugin --enable-default-pie --with-system-zlib --enable-libphobos-checking=release --with-target-system-zlib=auto --enable-objc-gc=auto --enable-multiarch --disable-werror --disable-multilib --with-arch=rv64gc --with-abi=lp64d --enable-checking=release --build=riscv64-linux-gnu --host=riscv64-linux-gnu --target=riscv64-linux-gnu --with-build-config=bootstrap-lto-lean --enable-link-serialization=2
Thread model: posix
Supported LTO compression algorithms: zlib zstd
gcc version 13.2.0 (Ubuntu 13.2.0-4ubuntu3-bb2)

If gcc is not installed in your system, you can install it with the following command:

sudo apt update
sudo apt install build-essential

Hello World test program

Create a new test file hello.c, you can use the touch command to create it in the command line:

touch hello.c

Edit the file content as follows:

#include <stdio.h>

int main() {
printf("Hello, World!\n");
return 0;


gcc -o hello hello.c

Run the generated program hello:


The output is as follows:

milkv@k1:~$ ./hello
Hello, World!
