zlib

Compilation (V1.2.3,V1.2.5,V1.2.7)

1. Unpack the sources, e.g.:

   gunzip -c zlib-1.2.3.tar.gz | tar -xvf -
   cd zlib-1.2.3
   

2. configure and run the Makefile:

                               # AIX 6.1, C 9.0; AIX 7.1, C 12.1 
   export CC=cc; export CFLAGS="-O2 -D_THREAD_SAFE -D_LARGE_FILES"; ./configure --static --prefix=/tmp/zlib-1.2.7
                               # AIX 4.1, C 3.6.6
   export CC=cc; export CFLAGS="-O2 -qmaxmem=-1"; ./configure --static --prefix=/tmp/zlib-1.2.5
                               # HP-UX 11.x
   export CC=cc; export CFLAGS="-O2";             ./configure          --prefix=/tmp/zlib-1.2.3
                               # HP-UX 11.x, shared library
   export CC=cc; export CFLAGS="-O2 +z";          ./configure --shared --prefix=/tmp/zlib-1.2.3
                               # HP-UX 10.20
   export CC=cc; export CFLAGS="-O -Ae";          ./configure          --prefix=/tmp/zlib-1.2.3
                               # HP-UX 10.20, shared library
   export CC=cc; export CFLAGS="-O -Ae +z";       ./configure --shared --prefix=/tmp/zlib-1.2.3
                               # HP-UX  9.10, vsnprintf() not supported
   export CC=cc; export CFLAGS="-O -Aa +e  -D_XPG2 -D_INCLUDE_POSIX_SOURCE -D_INCLUDE_HPUX_SOURCE -D_INCLUDE_XOPEN_SOURCE -D_INCLUDE_AES_SOURCE"; ./configure --prefix=/tmp/zlib-1.2.3
   
   make clean
   make
   make install 
   

   Note: The configure script has a bug for --static, the generated Makefile uses the variable SHAREDLIBV, which naturally is undefined in this case. Correct manually.
3. Copy installation to its final location, e.g.

   cp -p -r -h /tmp/zlib-1.2.3 /opt
   

   For easier version control it is convenient to place links ("stow") like

   ln -s /opt/zlib-1.2.3/lib/libz.a      /opt/lib/libz.a
   

   and refer to these links only.

1. Unpack the sources, e.g.:

   gunzip -c zlib-1.2.3.tar.gz | tar xvf -
   cd zlib-1.2.3
   

2. configure and run the Makefile:

   export CC=cc ; ./configure --prefix=/local
   make
   make install prefix=
   make clean
   

3. For easier version control it is convenient to place links ("stow") like

   ln -s /opt/zlib-1.2.3/lib/libz.a      /opt/lib/libz.a

Checking for snprintf() in stdio.h... No.
  WARNING: snprintf() not found, falling back to sprintf(). zlib
  can build but will be open to possible buffer-overflow security
  vulnerabilities.
Checking for return value of sprintf()... No.
  WARNING: apparently sprintf() does not return a value. zlib
  can build but will be open to possible string-format security
  vulnerabilities.
