Hi,
The problem is partially due to where the -lname bits are. They should
be put at the end of the line (after all options and stuff). You also
needed to include libz (-lz) and libjpeg (-ljpeg).
This worked for me:
$ gcc -static -o tifft tifft.c -lm -ltiff -ljpeg -lz
P.s. I renamed your file to tifft.c, still using your code.
