Cross compilation

[jwinarske]

What is the expected method for cross compiling?

Snippet from install.js

const config = [
	'./configure --disable-gifview --disable-gifdiff',
	`--prefix="${bin.dest()}" --bindir="${bin.dest()}"`
].join(' ');

try {
	await binBuild.file(path.resolve(__dirname, '../vendor/source/gifsicle-1.92.tar.gz'), [
		'autoreconf -ivf',
		config,
		'make install'
	]);

It cross compiles as desired if I add --host=${TARGET_SYS} to config.

Using export ac_cv_build="${TARGET_SYS}" has no impact.

This is the dramatic error when --host is not set when trying to cross compile.
