The problem in building opencv via eclipse

[茂实丁]

Hello everybody!

I'm trying to compile opencv example in eclipse enviroment.I followed the doc https://community.freescale.com/docs/DOC-106613

.I modified  the  makefile.am like the following :

------------------------------------------------------------

bin_PROGRAMS = opencv_sample

opencv_sample_SOURCES = opencv_sample.cpp

AM_CXXFLAGS = @opencv_sample_CFLAGS@ -I/home/ding/fsl-community-bsp/buildimx/tmp/sysroots/imx6sxsabresd/usr/include

AM_LDFLAGS = @opencv_sample_LIBS@   -L/opt/poky/1.8/sysroots/armv7a-vfp-neon-poky-linux-gnueabi/opencvlib  -lopencv_core  -lopencv_highgui  -lopencv_imgproc -lopencv_photo

CLEANFILES = *~

-------------------------------------------------------------------------------------

but the eclipse console always says:

-------------------------------------------------------------------------------------

make  all-recursive

make[1]: 正在进入目录 `/home/ding/workspace/opencv_sample'

What's the problem? ?

Best regards!  Thank you!

PS :I can build "hello world " successfully. If i add -L/opt/poky/1.8/sysroots/armv7a-vfp-neon-poky-linux-gnueabi/opencvlib ,file /lib/libc.so.6 .etc will missed.  If delete -L/XXX/XXX ，it can't find the library path. I have modifid ld.so.conf file in sysroots ，but it's useless .

What is the right way to add library path in eclipse?

Best  regards！

Thank you yuri!   I used the wrong tool-chain.:smileyblush:
