Good, thanks for the info, learn something new about make all the time.

The change was made in the nan package to fix a specific problem, see http://hg.code.sf.net/p/octave/NaN/rev/3931a2259cb2

Not sure if this should be addressed in configure_make.m as you suggest or if it's limited scope enough to be fixed in one package. Nan package could try setting CC with something like

CC := $(shell $(MKOCTFILE) -p CC)

running make --no-builtin-variables, makes it use the ?= rule.

So I guess internally, make sets CC to cc, prior to checking ?= etc.

Running make -p | grep CC:

bash-3.1$ make -p | grep CC
CC=cc
LINK.o = $(CC) $(LDFLAGS) $(TARGET_ARCH)
CC = cc
CPP = $(CC) -E

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.

The NaN package Makefile contains

CC ?= gcc

so does that mean CC is "cc" in the Octave environment on Windows? If so, how is that environment configured, is it by Octave, Windows, or other?

In regards to running make from pkg install, I see that when it invokes configure, if the env vars for CC etc are not set, it uses those from mkoctfile.

When calling make, it doesn't not - in the case where there is a makefile, but not a configure script, should it pass along CC etc?

Running setenv('CC', 'gcc') prior to pkg install and it will install ok.

Using mxe-octave, running in Windows 7.

>> pkg install -verbose -forge nan
.
.
.
cc -fopenmp -Wall -Wextra -Wconversion -O2  -fopenmp  -c svm.cpp
make: cc: Command not found
make: *** [svm.o] Error 127
.

3.0 fails at the same place.

2.8.1 installs ok.
