Losing euid

make -v gives:

uname -a gives:

AIX enterprise2 2 4 002034865900

I believe this means version 4 release 2 of AIX.


I'm trying to run "make" from a process which has the effective user id set, 
but once in "make" this is lost.

To demonstrate this I have a script, "runmake.sh" that contains:

#!/bin/sh
id
make

and a Makefile that contains:

all:
        @echo In Makefile
        @id

and a binary executable, "runmake", which simply calls execv for "runmake.sh".  
"runmake" has setuid set.

When "runmake" is executed I get the following output:

$ runmake
Running runmake.sh
uid=233(mr) gid=261(tardis) euid=234(mint) groups=1(staff)
In Makefile
uid=233(mr) gid=261(tardis) groups=1(staff)
$ 

Note the euid is lost once in the Makefile.

I had an identical problem on Solaris a year back with version 3.78.1and it was 
solved.  I don't know if this is a similar problem on AIX but here is the 
solution given followed by my current config.h.

I found the problem.

If you have autoconf installed, you can edit configure.in and reverse
the lines:

  AC_FUNC_GETLOADAVG
  AC_CHECK_LIB(kstat, kstat_open)

so they read:

  AC_CHECK_LIB(kstat, kstat_open)
  AC_FUNC_GETLOADAVG

Then re-run autoconf ("autoconf"), then remove the config.cache file and
re-run configure.

That should do it.

Or, you can use the workaround I cited in my previous message, and
hand-edit config.h.

The next version of GNU make will contain this fix.
