System name: marathon
Type and version: SPARC/4 8.1.11 (with mkserv)
Display type: cgthree
What were you trying to do?
Use Solaris 2.5 make as documented
What's wrong:
_______________________________________________________________________________
( setenv MAKEFLAGS "CC=$COMPILER CC2=$COMPILER" ; make -f makefile.test test1 )
echo gcc gcc
gcc gcc
echo MAKEFLAGS=$MAKEFLAGS
MAKEFLAGS=
( setenv MAKEFLAGS "CC=$COMPILER CC2=$COMPILER" ; make -f makefile.test )
make -f makefile.test test1
echo cc cc
cc cc
echo MAKEFLAGS=$MAKEFLAGS
MAKEFLAGS=
echo MAKEFLAGS=$MAKEFLAGS
MAKEFLAGS=
_______________________________________________________________________________
makefile.test:
CC= cc
CC2= cc
all:
$(MAKE) -f makefile.test test1
echo MAKEFLAGS=$$MAKEFLAGS
test1:
echo $(CC) $(CC2)
echo MAKEFLAGS=$$MAKEFLAGS
_______________________________________________________________________________
What should have happened:
In both cases, "gcc gcc" should have been printed,
and the MAKEFLAGS environment variable should have been
preserved.
Please describe any relevant documentation references:
the man page:
The MAKEFLAGS variable will be accessed from the environment
before the makefile is read. At that time, all of the
options (except -f and - p) and command-line macros not
already included in MAKEFLAGS are added to the MAKEFLAGS
macro. The MAKEFLAGS macro will be passed into the environ-
ment as an environment variable for all child processes. If
the MAKEFLAGS macro is subsequently set by the makefile, it
replaces the MAKEFLAGS variable currently found in the
environment.
