hi i'm having troubles in eclipse including opencv library. follow lot of tutorials can't compile anything. here output console.

building file: ../hand.c invoking: cygwin c compiler gcc -o2 -g -wall -c -fmessage-length=0 -mmd -mp -mf"hand.d" -mt"hand.d" -o"hand.o" "../hand.c" cygwin warning:   ms-dos style path detected: d:\eclipse_workspace_c++\helloworld\default   preferred posix equivalent is: /cygdrive/d/eclipse_workspace_c++/helloworld/default   cygwin environment variable option "nodosfilewarning" turns off warning.   consult user's guide more details posix paths:     http://cygwin.com/cygwin-ug-net/using.html#using-pathnames ../hand.c:3:16: fatal error: cv.h: no such file or directory compilation terminated. subdir.mk:18: recipe target `hand.o' failed make: *** [hand.o] error 1

i'm using opencv2.0.

i configured in proyect properties c/c++ build -> settings -> tool settings tab -> compiler , linker add library , headers of opencv can not compile it.

screenshoot of eclipse project.

enter image description here

solved!

steps configure eclipse , opencv 2.4.5 in windows

1) after installing opencv include in environment path directory opencv installed, mine opencv\opencv2.4.5\build\include

2) use cygwin compile c files. configure eclipse using cdt cygwin , in project setting put next configuration.

settings compiler

settings linker

if using mingw put there in linker settings. me it's vc9.

3)my source file like

  #include <stdio.h>     #include <stdlib.h>      #include <cv.h>      int main(void) {         puts("hello world!!!");         return exit_success;     }
