#2908: Cactus: Fixed arg list too long error.

Reporter: Max Morris Status: open Milestone: Version: Type: bug Priority: major Component:

Comment (by Roland Haas):

The key line in the proposed change is

``` OBJS-bytes := $(shell (echo -n $(OBJS) | wc --bytes) 2>/dev/null || echo -1) ```

However making a small dummy Makefile:

``` # make a long set of arguments >2million OBJS=$(shell awk 'BEGIN{for(i=0;i<200000;i++) print "01234567890";exit'})

OBJS-bytes := $(shell (echo -n $(OBJS) | wc --bytes) 2>/dev/null || echo -1)

$(info $(OBJS-bytes)) ```

and running via

``` make -f Makefile ```

on my Debian based Linux box I get:

``` haengie2: ~/tmp$ make -f Makefile make: /bin/sh: Argument list too long

make: *** No targets. Stop. ```

ie not the expected output of either `-1`or the length of `OBJS`. So this does not seem to work for me.
