[Buildroot] OpenCV compilation Error

[Buildroot] OpenCV compilation Error

[Parsa Panahi]

 

Hi 

I checked opencv to be included in my kernel but When I make the
buildroot it gives the following error for the opencv package. 

It seems it didn't find the gcc/cmake cannot compile the package. what's
wrong and what should I do ?

This is a strange name for the g++ compiler. Can you share your .config file?

It seems the toolchainfile.cmake is wrongly generated.
Could you share your .config file?

Also could you tell us more about the step you've done to setup your
configuration (e.g.: "make blabla_defconfig", then: "make menuconfig"
and change this and that toolchain options)?


As a quick fix, you can try the following:
rm /home/parsa/Software/buildroot/buildroot-2014.02/output/host/usr/share/buildroot/toolchainfile.cmake
then, rerun the build

All right, I've attached my config file.
