maybe you should add some library path by using the '-L' option to your
gcc command line, so that gcc can find the shared library?

I've just tried; the following compile command works:

gcc -L/sw/lib -I/sw/include -Wall -O2 -funroll-loops  -lppm ppmtoyuv4mpeg.c -o 
ppmtoyuv4mpeg

btw, the following makefile was used for creating the stills used in the
new test svcd's...

just put a pnm-file, e.g. mymenu.pnm (possibly w/ a 3:4 ratio) in the same
directory as the Makefile, and then just do a 'make mymenu_704_576.m2p'
for generating a hi-res SVCD still...

this makefile rules can be easily be developed into a more powerful
framework of rules...
