Patch 1478 Compile error on AIX 4.3 with zlib and IBM C-Compiler
As reported in bug 1478, I've also encountered the same problem on AIX 5
with openssl-0.9.8d.
Firstly, it is very important the OpenSSL package use the correct library
paths when referencing the zlib components, as it is very common for
multiple versions of the zlib libraries to exist on AIX. For example:
[1] AIX 5 ships the older version 1.2.2 zlib libraries as part of rpm.rte
package. These are located as /usr/lib/libz.a ->
/usr/opt/freeware/lib/libz.a
[2] Downloading the zlib 1.2.3 source and compiling using defaults places
the library in /usr/local/lib.
Knowing this, I believe I've identified some defects in the Makefiles that
enable me to resolve the problem described in bug 1478 as well as identify
the correct zlib libraries. The resolution was to perform the following
changes:
1) extract the source code for openssl-0.9.8d
2) Insert a new line 183 to file openssl-0.9.8d/Makefile.org
ZLIB_INCLUDE='${ZLIB_INCLUDE}' LIBZLIB='${LIBZLIB}' \
3) Edit line 1115 of file openssl-0.9.8d/Configure
from:
$lflags = "$lflags -lz";
and change to:
$lflags = "$lflags -L" . $withargs{"zlib-lib"} . " -lz";
4) Edit line 13 of file openssl-0.9.8d/crypto/comp/Makefile
from:
CFLAGS= $(INCLUDES) $(CFLAG)
and change to:
CFLAGS= $(INCLUDES) $(ZLIB_INCLUDE) $(CFLAG)
5) Run the Configure as follows:
./Configure aix-cc zlib \
--with-zlib-lib=/usr/local/lib \
--with-zlib-include=/usr/local/include
6) Make and run the tests as normal.
All seems to be fine so far. Hope this proves useful for a formal patch.
Regards,
Kieron Curtis.
