Three questions:
What is ARM-GCC? How does it relate to GCC?
The compilation toolchain and the target program run on the same architecture platform, which is called local compilation
The compilation toolchain and the target program run on different architecture platforms, which is called cross-compilation
ARM-GCC is a compiler for the arm platform, which is a branch of the GCC compilation tool chain
virtual machine
development board
What are the further classifications of ARM-GCC?
The second item: linux none
The third item: gnu: glibc eabi: application binary standard interface hf: support hard floating point platform
How to install ARM-GCC?
apt install gcc
When using the installation command on different platforms, the gcc tool compilation chain of different platforms will be installed
install arm-gcc on ubuntu
apt install gcc-arm-linux-gnueabihf
Linaro
Two cases:
Here you can see that the development board has recognized the shared folder of ubuntn
Now mount the ubuntn shared folder to the development board
Programs running x86_64 architecture on ARM architecture
cp the hello executable file of the virtual machine to the shared folder
Switch to superuser on the development board and compile
Executable format errors are found, indicating that executable programs on different platforms cannot be mixed because the executable file formats are different from each other
Run cross-compiled programs on the ARM architecture
The development board can be compiled normally
