i follow what the book says (C a modern approach, king, 2ed) and type

gcc -o load histogram.c jpeg32.o Lenna.jpg.

it gives an error

Lenna.jpg: file not recognized: File format not recognized.

i used #include "/MinGw/bin/jpeg.h" in the header. the file jpeg.h is in c:\\MinGw\bin\

is this not correct?
