This is C++ code and does not belong in a source file with .c extension.

A static library for x86_64 will be of no use when compiling ARM
executables. This is really not an issue for the devel list, there is
nothing wrong with how Fedora is developed here, it is a user error.
> dnf install -y llvm
> dnf install -y glib-static
Here, you are not specifying the architecture explicitly, but if this is on
an x86_64 host, you are going to get the x86_64 versions of these too. (And
you almost certainly do not want glib (version 1), maybe glib2, or did you
mean glibc?)
> arm-none-eabi-g++
Are you sure you want to target arm-none-eabi and not arm-linux-gnueabi or
even aarch64-linux-gnu? What device are you targeting? If it runs some form
of GNU/Linux, try:
https://copr.fedorainfracloud.org/coprs/lantw44/arm-linux-gnueabi-toolchain/
or:
https://copr.fedorainfracloud.org/coprs/lantw44/aarch64-linux-gnu-toolchain/
instead of the arm-none-eabi target.
arm-none-eabi is a generic freestanding (no operating system) target. It
assumes you explicitly link to an implementation of some basic operating
system functions, or even include them as part of your source code. (It is
common for devices truly without an operating system to build an application
with a bundled small operating system, typically an RTOS (real-time
operating system).) For devices with an operating system, you should instead
use the specific target corresponding to that operating system.
In short, this is off-topic for this list, there are many issues with what
you are doing, and none in Fedora so far.

This list is for developing fedora itself, not a programming development list.
I think you are better off asking on the fedora arm mailing list or the fedora
users mailing list.

compile a basic example to arm executable on Fedora
I try to create a hello word arm static executable, with the default example
but I got these errors.
I search on the web and fedora packages to find a way to solve this issue.
I used a basic example source code:
cat hello.c
#include
using namespace std;
int main(void)
{
std::cout << "Hello word! from Fedora Linux!" << std::endl;
return 0;
}
I install wit the dnf tool
dnf install -y libstdc++-static.x86_64
dnf install -y llvm
dnf install -y glib-static
I try also with -static and
arm-none-eabi-g++ -static-libstdc++ hello.c -o arm_hello-static
but , I got these errors, any help ?
