| 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/ )

|
|---|
| 11 | # Invoke this makefile from a DOS-prompt window via:
|
|---|
| 12 | #
|
|---|
| 13 | # make -f Makefile.mingw32
|
|---|
| 14 | #
|
|---|
| 15 | # This makefile assumes libpng and zlib have already been built or downloaded
|
|---|
| 16 | # and are in subdirectories at the same level as the current subdirectory
|
|---|
| 17 | # (as indicated by the PNGDIR and ZDIR macros below). It makes no assumptions
|
|---|
| 18 | # at all about the mingw32 installation tree (W32DIR). Edit as appropriate.
|
|---|
| 19 | #
|
|---|
| 20 | # Note that the names of the dynamic and static libpng and zlib libraries
|
|---|
| 21 | # used below may change in later releases of the libraries. This makefile
|
|---|
| 22 | # builds both statically and dynamically linked executables by default.
|
|---|
| 23 | # (You need only one set, but for testing it can be handy to have both.)
