interactive shell is incorrect

[David Thompson]

Hi,

Could someone explain this behavior?

The first question I have is on line 49, here is my setup,

     1  $ uname -a
     2  Linux proton 2.4.18-27.7.xsmp #1 SMP Fri Mar 14 05:52:30 EST 2003 i686
       
     3  $ config.guess --timestamp
     4  2003-05-22
       
     5  $ config.guess
     6  i686-pc-linux-gnu
       
     7  $ cd ~/tmp
     8  $ mkdir foo
     9  $ cd foo
    10  $ cp ../Makefile.a .
    11  $ cp ../Makefile.b .
       
    12  $ cat Makefile.a
    13  all:
    14          gmake -f Makefile.b SHELL=/usr/local/bin/bash
       
    15  $ cat Makefile.b 
    16  TOPDIR := $(shell /bin/pwd)
    17  all:
    18          echo TOPDIR = $(TOPDIR)
       
    19  $ ls -la
    20  total 92
    21  drwxrwxr-x   2 davidt   eng   4095 Jun  4 22:03 .
    22  drwxrwxrwx   7 davidt   eng  86016 Jun  4 22:01 ..
    23  -rw-rw-r--   1 davidt   eng     52 Jun  4 22:01 Makefile.a
    24  -rw-rw-r--   1 davidt   eng     58 Jun  4 22:02 Makefile.b
       
    25  $ echo $SHELL
    26  /usr/local/bin/ksh
       
    27  $ echo ${.sh.version}
    28  Version M 1993-12-28 m+
       
    29  $ ls -l ~/.bash*
    30  -rw-r--r--   1 davidt   eng     24 Jun  4 22:08 
/home/davidt/.bash_profile
    31  -rw-r--r--   1 davidt   eng     18 Jun  4 22:09 /home/davidt/.bashrc
       
    32  $ cat ~/.bash_profile
    33  echo Hello bash_profile
       
    34  $ cat ~/.bashrc
    35  echo Hello bashrc
       
    36  $ bash --version
    37  GNU bash, version 2.05.0(1)-release (i686-pc-linux-gnu)

    39  $ make --version

    45  $ pwd
    46  /home/davidt/tmp/foo
       
    47  $ make -s -f Makefile.a
    48  Hello bashrc
    49  TOPDIR = Hello bashrc /home/davidt/tmp/foo
                 ^^^^^^^^^^^^
Why is the shell invoked interactively?  I mean, bash sources
the ~/.bashrc file only if bash is interactive, right?  So,
line 48 and 49 are clearly wrong.  But line 49 looks worse.
       
    50  $ make -s -f Makefile.b
    51  TOPDIR = /home/davidt/tmp/foo

Note how Makefile.b has no problems.
       
    52  $ make -s -f Makefile.a SHELL=/usr/local/bin/bash
    53  Hello bashrc
    54  TOPDIR = /home/davidt/tmp/foo

Note how line 54 differs from line 49.
       
    55  $ make -s -f Makefile.a SHELL=/usr/local/bin/ksh 
    56  Hello bashrc
    57  TOPDIR = Hello bashrc /home/davidt/tmp/foo

Note how line 57 differs from line 54, but is the same as
line 49.

Can someone explain this behavior?  And what is the correct
behavior?  I assume only line 51 shows correct behavior.

Is this 0, 1, or 2 bugs?  Is this a known bug?
