Getting platformio to compile using NASM

1

I’ve got a simple x86 assembly program I’m trying to build built under platformio.

I’ve got a bash script that calls

nasm -f bin -o build/main.bin src/main.asm
xxd -p build/main.bin build/main.hex

And now I’m trying to integrate it into PlatformIO so when I click on the build button it calls the script and compiles the asm file.

platformio.txt

[env:8088]
platform = native

# Custom build steps
build_flags = 
    -D CUSTOM_BUILD=1

# Define the build scripts
extra_scripts = pre:build_script.sh

However I get:

    nasm -f bin -o build/main.bin src/main.asm

            ^^^

SyntaxError: invalid syntax

Am I misunderstanding how to use the extra_scripts?

How do I get this working?

The PlatformIO Build System allows the user to extend the build process with custom scripts using the Python interpreter and the SCons construction tool…
