运行该工程需要安装opencv，先要安装opencv。

opencv安装成功后，下载linux下的源码，之后make发生以下错误

wenbo@wenbo-computer:~/学习/特征提取/sift/sift/src$ make

gcc -I../include `pkg-config --cflags opencv gtk-engines-2` -c imgfeatures.c -o imgfeatures.o

Package gtk-engines-2 was not found in the pkg-config search path.

Perhaps you should add the directory containing `gtk-engines-2.pc'

to the PKG_CONFIG_PATH environment variable

No package 'gtk-engines-2' found

In file included from imgfeatures.c:9:

../include/utils.h:12: fatal error: cxcore.h: 没有那个文件或目录

compilation terminated.

make: *** [imgfeatures.o] 错误 1

找不到gtk-engines-2，可以找到/usr/lib/pkgconfig/gtk+-2.0.pc，所以将gtk-engines-2该为gtk-2.0。

wenbo@wenbo-computer:~/学习/特征提取/sift/sift/src$ make

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` -c imgfeatures.c -o imgfeatures.o

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` -c utils.c -o utils.o

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` -c sift.c -o sift.o

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` -c kdtree.c -o kdtree.o

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` -c minpq.c -o minpq.o

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` -c xform.c -o xform.o

ar rc ../lib/libfeat.a imgfeatures.o utils.o sift.o kdtree.o minpq.o xform.o

ranlib ../lib/libfeat.a

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` siftfeat.c -o ../bin/siftfeat -L../lib -lfeat `pkg-config --libs opencv gtk+-2.0`

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` match.c -o ../bin/match -L../lib -lfeat `pkg-config --libs opencv gtk+-2.0`

gcc -I../include `pkg-config --cflags opencv gtk+-2.0` dspfeat.c -o ../bin/dspfeat -L../lib -lfeat `pkg-config --libs opencv gtk+-2.0`

成功！
