    Hello!

    I'm trying to compile sendmail 8.11.7 on my aix 5.2 ml6 test box. I'm
    doing this to try and prove that it's not really the sendmail binary that
    is core dumping on me. SPecifically, the default Sendmail is providing me
    with messages like this periodically.

    My first thought was that it was paging space. But I'm in good shape on
    that ( or so I think!) :

    # lsps -a
    Page Space Physical Volume Volume Group Size %Used Active Auto Type
    paging00 hdisk1 rootvg 16384MB 2 yes yes lv
    hd6 hdisk0 rootvg 512MB 64 yes yes lv

    So I started compiling my own Sendmail using the 8.11.7 sources, since I
    don't really want to move to 8.12 or 8.13 . I'm using the IBM C compiler
    and gcc.

    vac.C 6.0.0.12 COMMITTED C for AIX Compiler

    # gcc -v
    Reading specs from /usr/local/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.4/specs
    Configured with: ../gcc-3.3.4/configure --disable-nls
    --enable-languages=c,c++
    Thread model: aix
    gcc version 3.3.4

    If I try and compile with the IBM C compiler I get the following messages
    very quickly :

    make[1]: Entering directory
    `/usr/local/src/sendmail-8.11.7/obj.AIX.5.2.PPC/libsmutil'
    cc -g -I. -I../../sendmail -I../../include -DNDBM -DNIS -D_AIX3
    -DNOT_SENDMAIL -c -o debug.o debug.c
    "../../sendmail/sendmail.h", line 2166.17: 1506-343 (S) Redeclaration of
    unsetenv differs from previous declaration on line 464 of
    "/usr/include/stdlib.h".
    "../../sendmail/sendmail.h", line 2166.17: 1506-050 (I) Return type "void"
    in redeclaration is not compatible with the previous return type "int".
    make[1]: *** [debug.o] Error 1

    In order to get around that, I added this line to my site.config.m4 file :

            APPENDDEF(`confENVDEF', `-DHASUNSETENV')

    Now when I compile it, I get these messages :

    cc -g -I. -I../../sendmail -I../../include -DNDBM -DNIS -D_AIX3
    -DHASUNSETENV -DNOT_SENDMAIL -c -o snprintf.o snprintf.c
    "snprintf.c", line 60.1: 1506-343 (S) Redeclaration of snprintf differs
    from previous declaration on line 267 of "/usr/include/stdio.h".
    "snprintf.c", line 60.1: 1506-378 (I) Prototype for function snprintf
    cannot contain "..." when mixed with a nonprototype declaration.
    "snprintf.c", line 60.1: 1506-376 (I) Redeclaration of snprintf has a
    different number of fixed parameters than the previous declaration.
    make[1]: *** [snprintf.o] Error 1

    If instead of the IBM C compiler I use gcc I get ...

    gcc -g -I. -I../../sendmail -I../../include -DNDBM -DNIS -D_AIX3
    -DNOT_SENDMAIL -c -o debug.o debug.c
    In file included from debug.c:15:
    ../../sendmail/sendmail.h:2166: error: conflicting types for `unsetenv'
    /usr/local/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.4/include/stdlib.h:489:
    error: previous declaration of `unsetenv'
    make[2]: *** [debug.o] Error 1

    Which goes away when I add this line to my site.config.m4:

            APPENDDEF(`confENVDEF', `-DHASUNSETENV')

    Using gcc, it then goes on to compile and work nicely. Except I need to
    add NEWDB support to it. So I compiled and installed the Berkeley Library
    and added it to my sit.config.m4 file as below :

            APPENDDEF(`confINCDIRS', `-I/usr/local/BerkeleyDB.4.3/include')
            APPENDDEF(`confLIBDIRS', `-L/usr/local/BerkeleyDB.4.3/lib')

    So now, when I try and compile it, I get :

    gcc -g -I. -I../../sendmail -I../../include
    -I/usr/local/BerkeleyDB.4.3/include -DNEWDB -DNDBM -DNIS -D_AIX3
    -DHASUNSETENV -DNOT_SENDMAIL -c -o smdb2.o smdb2.c
    smdb2.c: In function `smdb_db_open_internal':
    smdb2.c:533: warning: passing arg 2 of pointer to function from
    incompatible pointer type
    smdb2.c:533: error: incompatible type for argument 4 of indirect function
    call
    smdb2.c:533: error: too few arguments to function

    Which looks bad to me. :-)

    Anyone seen this before ?

    Thansk!
