| 5 | # The programs built by this makefile are described in the book,
|
|---|
| 6 | # "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and
|
|---|
| 7 | # Associates, 1999). Go buy a copy, eh? Well, OK, it's not
|
|---|
| 8 | # generally for sale anymore, but it's the thought that counts,
|
|---|
| 9 | # right? (Hint: http://www.libpng.org/pub/png/book/ )
|

| 10 | #
|
|---|
| 11 | # Invoke this makefile from a DOS prompt window via:
|
|---|
| 12 | #
|
|---|
| 13 | # %devstudio%\vc\bin\vcvars32.bat
|
|---|
| 14 | # nmake -nologo -f Makefile.w32
|
|---|
| 15 | #
|
|---|
| 16 | # where %devstudio% is the installation directory for MSVC / DevStudio. If
|
|---|
| 17 | # you get "environment out of space" errors, create a desktop shortcut with
|
|---|
| 18 | # "c:\windows\command.com /e:4096" as the program command line and set the
|
|---|
| 19 | # working directory to this directory. Then double-click to open the new
|
|---|
| 20 | # DOS-prompt window with a bigger environment and retry the commands above.
|
|---|
| 21 | #
|
|---|
| 22 | # This makefile assumes libpng and zlib have already been built or downloaded
|
|---|
| 23 | # and are in subdirectories at the same level as the current subdirectory
|
|---|
| 24 | # (as indicated by the PNGPATH and ZPATH macros below). Edit as appropriate.
|
|---|
| 25 | #
|
|---|
| 26 | # Note that the names of the dynamic and static libpng and zlib libraries
|
|---|
| 27 | # used below may change in later releases of the libraries. This makefile
|
|---|
| 28 | # builds statically linked executables, but that can be changed by uncom-
|
|---|
| 29 | # menting the appropriate PNGLIB and ZLIB lines.
