README.md

The arm-stmos toolchain

A special binutils/gcc toolchain is necessary to build stmos and associated programs. For convenience, a bash script has been written to attempt to automate the majority of the compilation/installation process. This process is based of off various tutorials from osdev.org.

Some programs are required for the build process. A list can be found here. Once installed, just run the script:

./create-toolchain.sh

It should be safe to re-run the script, if necessary.

After successful installation, be sure to add the toolchain to your path ($HOME /arm-stmos/bin). Then, follow these steps to build pdclib and the crt0:

Cd to src/pdclib
Make sure the Makefile does not have the -g flag set under CFLAGS
Build pdclib (make)
Copy pdclib.a to ~/arm-stmos/lib/gcc/arm-stmos/8.2.0/libc.a
Add the -g flag to CFLAGS in the Makefile; Rebuild pdclib
Copy pdclib.a to ~/arm-stmos/lib/gcc/arm-stmos/8.2.0/libg.a
Cd to the stmos root directory; run make crt
Copy crt0.o ~/arm-stmos/lib/gcc/arm-stmos/8.2.0/crt0.o

Now everything should be ready. Build stmos, run it, hope it works.
