[Buildroot] opencv with glibc

[Samuel Martin]

hi,

Ozgun: you want to use a glibc toolchain, right?

your .config file say that, contrary to your logs:
>> CMake Error: your CXX compiler:
>> "/usr/src/br/buildroot/output/host/usr/bin/i686-unknown-linux-uclibc-g++"
>> was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or

before changing your configuration to build a ct-ng glibc toolchain,
did you run 'make clean', 'make distclean' ?
if yes, then there is a bug in BR that does not delete the
toolchainfile.cmake when calling clean/distclean target.

btw, removing the buildroot/output/toolchainfile.cmake  and running
make again should fix your issue.

regards,

Sam
