Building Jonesforth - asm/unistd.h: No such file or directory

Question

When attempting to build Jonesforth (32-bit GNU Assembler program) on Ubuntu 16.04.4 64-bit (Xenial Xerus), I'm seeing the following:

~/src/jonesforth $ make
gcc -m32 -nostdlib -static -o jonesforth jonesforth.S
jonesforth.S:1154:24: fatal error: asm/unistd.h: No such file or directory
compilation terminated.
Makefile:11: recipe for target 'jonesforth' failed

Looking in the file jonesforth.S , I noticed the following lines:

//#include <asm-i386/unistd.h>  // You might need this instead
#include <asm/unistd.h>

I've tried using asm-i386/unistd.h instead, but that also didn't seem to help.

Is the best course of action to install more headers via sudo apt install linux-headers... ? If so, which should I go with? Should linux-headers-generic be sufficient?

Or, should I change the header that jonesforth.S is referring to?

Answer 1

Adding -I /usr/include/x86_64-linux-gnu to the make recipe seems to have solved the issue:

jonesforth: jonesforth.S
        gcc -I /usr/include/x86_64-linux-gnu -m32 -nostdlib -static $(BUILD_ID_NONE) -o $@ $<

Thanks to the suggestion from Peter Cordes above!
