The variable $MESON_CROSSFILE should be quoted to handle potential spaces in paths. Without quotes, the test will fail if the path contains spaces. Change to if [ -e "$MESON_CROSSFILE" ]; then.

Suggested change

	if [ -e $MESON_CROSSFILE ]; then
	if [ -e "$MESON_CROSSFILE" ]; then

The variable $MESON_CROSSFILE should be quoted to prevent word splitting. Without quotes, paths with spaces will cause the command to fail. Change to MESON_OPTION=\"$MESON_OPTION --cross-file $MESON_CROSSFILE -Dstatic-linkage=true\".

Suggested change

	MESON_OPTION="$MESON_OPTION --cross-file $MESON_CROSSFILE -Dstatic-linkage=true"
	MESON_OPTION="$MESON_OPTION --cross-file \"$MESON_CROSSFILE\" -Dstatic-linkage=true"

The variable $MESON_CROSSFILE should be quoted to handle potential spaces in paths. Without quotes, the cat command will fail if the path contains spaces. Change to cat \"$MESON_CROSSFILE\".

Suggested change

	cat $MESON_CROSSFILE
	cat "$MESON_CROSSFILE"
