hi, today tried compile opencv raspberry pi on pc, there 1 error, can't fix...

toolchain file i'm using file /platform/linux/arm-gnueabi.toolchain.cmake have made couple of changes in beginning of file

set(cmake_system_name linux)
set(cmake_system_version 1)
set(cmake_system_processor arm)

set(gcc_compiler_version "4.8.3" cache string "gcc compiler version")
set(float_abi_suffix "hf")

set(cmake_c_compiler arm-linux-gnueabihf-gcc)
set(cmake_cxx_compiler arm-linux-gnueabihf-g++)
set(arm_linux_sysroot /home/hristov/workspace/rootfs)

set(cmake_cxx_flags "" cache string "c++ flags")
set(cmake_c_flags "" cache string "c flags")
set(cmake_shared_linker_flags "" cache string "shared linker flags")
set(cmake_module_linker_flags "" cache string "module linker flags")
set(cmake_exe_linker_flags "-wl,-z,nocopyreloc" cache string "executable linker flags")

set(cmake_cxx_flags "${cmake_cxx_flags} -fdata-sections -wa,--noexecstack -fsigned-char -wno-psabi")
set(cmake_c_flags "${cmake_c_flags} -fdata-sections -wa,--noexecstack -fsigned-char -wno-psabi")

set(cmake_shared_linker_flags "-wl,--fix-cortex-a8 -wl,--no-undefined -wl,--gc-sections -wl,-z,noexecstack -wl,-z,relro -wl,-z,now ${cmake_shared_linker_flags}")

set(cmake_module_linker_flags "-wl,--fix-cortex-a8 -wl,--no-undefined -wl,--gc-sections -wl,-z,noexecstack -wl,-z,relro -wl,-z,now ${cmake_module_linker_flags}")

set(cmake_exe_linker_flags "-wl,--fix-cortex-a8 -wl,--no-undefined -wl,--gc-sections -wl,-z,noexecstack -wl,-z,relro -wl,-z,now ${cmake_exe_linker_flags}")

compilation fails, when tries make ".a" static library file object files, can't understand file cannot found ? of object files or other ?
