Re: Compilation failure

pngdbl.c:7:17: png.h: No such file or directory
pngdbl.c:17: error: parse error before "png_uint_32"
pngdbl.c:17: warning: no semicolon at end of struct or union

Let's start with this first error.

The fact it doesn't recognize the png.h that's because you didn't include it
make file.
First find out if you have installed libpng.a/.so and png stuff.
find / -name "png.h" -print

Once you find out where it is, 
in your gcc command line:
gcc -I/yourpngincludepathhere lkj.c lkjs.c -L/yourpnglibpathhere -lpng
That's it.
You're also going to have to do it with 
export PATH=$PATH:/home/david/gcc31tars/gcc-3.1/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/david/gcc31tars/gcc-3.1/lib
gcc -I ../../ming-0.2a/ -L ../../ming-0.2a/ astral.c -lming -lm
a

In my makefile I have this:
CC = gcc -g -Wall -I /home/david/devstuff/flashstuff/ming-0.3a/ming/ -L
/home/david/devstuff/flashstuff/ming-0.3a/ming/

makefdb: blocktypes.o makefdb.c read.o
	${CC} makefdb.c read.o blocktypes.o -o makefdb -lming -lm -lz -lungif -lpng

gif2mask: gif2mask.c
	${CC} gif2mask.c -o gif2mask -lungif -lm -lz

Notice png ungif and the rest aren't in the -I and -L switches that's because
they are in the default include and lib directories for my linux box.  Depending
on what version of linux they get install in few different places:
/usr/include
/usr/lib
/usr/share/sdfslfkj/include
/usr/share/sdflkj/lib
/usr/local/include
/usr/local/lib
It just depends on your machine.

one more thing.  Read up on ldconfig and ldd.  They are helpful also but I
personal prefer LD_LIBRARY_PATH because the libs are only for the process you
are in.  I don't want to make this stuff global for every process.  You can
though.

When you're doing this make a note of the following in order for everybody else
here:
1)what's your os and version
2)what your compiler and version
3)mods you made to the makefile and the rest of the ming cvs source tree.  There
are ways to diff an entire tree and send the results to a text file which can be
applied to ming cvs later by the authors.

If your source tree was checked out of CVS, 
cvs diff -u >my.unified.diff.patch

will create the patch in the correct format.

Here is a demonstration of what I mean:
