-Installing libpng version 1.2.20 - September 8, 2007
+Installing libpng
On Unix/Linux and similar systems, you can simply type
and ignore the rest of this document.
-If configure does not work on your system and you have a reasonably
-up-to-date set of tools, running ./autogen.sh before running ./configure
-may fix the problem. You can also run the individual commands in
-autogen.sh with the --force option, if supported by your version of
-the tools. If you run 'libtoolize --force', though, this will replace
-the distributed, patched, version of ltmain.sh with an unpatched version
-and your shared library builds may fail to produce libraries with the
-correct version numbers.
+If configure does not work on your system, or if you have a need to
+change configure.ac or Makefile.am, and you have a reasonably
+up-to-date set of tools, running ./autogen.sh in a git clone before
+running ./configure may fix the problem. To be really sure that you
+aren't using any of the included pre-built scripts, you can do this:
+
+ ./configure --enable-maintainer-mode
+ make maintainer-clean
+ ./autogen.sh --maintainer --clean
+ ./autogen.sh --maintainer
+ ./configure [--prefix=/path] [other options]
+ make
+ make install
+ make check
Instead, you can use one of the custom-built makefiles in the
"scripts" directory
make test
make install
-Or you can use one of the "projects" in the "projects" directory.
-
-If you want to use "cmake" (see www.cmake.org), copy CMakeLists.txt
-from the "scripts" directory to this directory and type
+The files that are presently available in the scripts directory
+are listed and described in scripts/README.txt.
- cmake . [-DPNG_MMX=YES] -DCMAKE_INSTALL_PREFIX=/path
- make
- make install
+Or you can use one of the "projects" in the "projects" directory.
Before installing libpng, you must first install zlib, if it
is not already on your system. zlib can usually be found
to have access to the zlib.h and zconf.h include files that
correspond to the version of zlib that's installed.
+If you wish to test with a particular zlib that is not first in the
+standard library search path, put ZLIBLIB, ZLIBINC, CPPFLAGS, LDFLAGS,
+and LD_LIBRARY_PATH in your environment before running "make test"
+or "make distcheck":
+
+ZLIBLIB=/path/to/lib export ZLIBLIB
+ZLIBINC=/path/to/include export ZLIBINC
+CPPFLAGS="-I$ZLIBINC" export CPPFLAGS
+LDFLAGS="-L$ZLIBLIB" export LDFLAGS
+LD_LIBRARY_PATH="$ZLIBLIB:$LD_LIBRARY_PATH" export LD_LIBRARY_PATH
+
+If you are using one of the makefile scripts, put ZLIBLIB and ZLIBINC
+in your environment and type "make ZLIBLIB=$ZLIBLIB ZLIBINC=$ZLIBINC test".
+
+If you want to use "cmake" (see www.cmake.org), type
+
+ cmake . -DCMAKE_INSTALL_PREFIX=/path
+ make
+ make install
+
You can rename the directories that you downloaded (they
-might be called "libpng-1.2.20" or "lpng109" and "zlib-1.2.1"
-or "zlib121") so that you have directories called "zlib" and "libpng".
+might be called "libpng-x.y.z" or "libpngNN" and "zlib-1.2.7"
+or "zlib127") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
README
*.h
*.c
+ CMakeLists.txt => "cmake" script
+ configuration files:
+ configure.ac, configure, Makefile.am, Makefile.in,
+ autogen.sh, config.guess, ltmain.sh, missing, libpng.pc.in,
+ libpng-config.in, aclocal.m4, config.h.in, config.sub,
+ depcomp, install-sh, mkinstalldirs, test-pngtest.sh

Copy the file (or files) that you need from the
scripts directory into this directory, for example
Read the makefile to see if you need to change any source or
target directories to match your preferences.
-Then read pngconf.h to see if you want to make any configuration
+Then read pnglibconf.dfa to see if you want to make any configuration
changes.
Then just run "make" which will create the libpng library in
Some also allow you to run "make test-installed" after you have
run "make install".
-If you encounter a compiler error message complaining about the
-lines
- __png.h__ already includes setjmp.h;
- __dont__ include it again.;
-This means you have compiled another module that includes setjmp.h,
-which is hazardous because the two modules might not include exactly
-the same setjmp.h. If you are sure that you know what you are doing
-and that they are exactly the same, then you can comment out or
-delete the two lines. Better yet, use the cexcept interface
-instead, as demonstrated in contrib/visupng of the libpng distribution.

+
+Using the ./configure script -- 16 December 2002.
+=================================================
+
+The ./configure script should work compatibly with what scripts/makefile.*
+did, however there are some options you might need to add to configure
+explicitly, which previously was done semi-automatically (if you didn't edit
+scripts/makefile.* yourself, that is)
+
+CFLAGS="-Wall -O -funroll-loops \
+-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
+--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
+
+You can alternatively specify --includedir=/usr/include, /usr/local/include,
+/usr/include/libpng%NN%, or whatever.
+
+If you find that the configure script is out-of-date or is not supporting
+your platform properly, try running autogen.sh to regenerate "configure",
+"Makefile.in", and the other configuration files. Then try configure again.
