[Octave-bug-tracker] [bug #47355] [forge]: NaN fails to install in windows

[John Donoghue]

Follow-up Comment #5, bug #47355 (project octave):


In octave:

>> getenv("CC")
ans =


In windows, using the msys make that is packaged with mxe octave,
test makefile:


CC ?= gcc

all:
        @echo "CC=$(CC)


Output is CC=cc

If I run make CC=gcc

Output is CC=gcc


If I change topline to CC := gcc

Output is CC=gcc

In Linux (I tested with fedora) it behaves the same ?= does not work for
setting CC to a default if CC is not externally set. (it sets it to cc
instead)

So it is at least consistant in the two OSs I tried.
