[Buildroot] Building opencv for OMAP4430 / Armv7 / Cmake problem

[Bruno Niklaus]

Hi @all

i tried to build opencv for armv7 / omap4430 processor, i'm using
codesourcery toolchain with neon optimations enabled.
when cmake tries to build opencv i allways get strange error with
*"z_offset64_t"*
The generated "toolchainfile.cmake" file in the "buildroot/outpout"
directory sets additional CMAKE_C_FLAGS and CMAKE_CXX_FLAGS at the end:
*"-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64"*
I dont think these are the right flags, if i delete them and rebuild opencv
i runs trough without any errors.
but i dont know where the toolchainfile.cmake is generated? Where should i
apply a patch?
And is it okay to just delete the flags or should there be other flags?

best regards
Bruno
