The CMAKE_{AR,LINKER,NM,OBJCOPY,OBJDUMP,RANLIB,STRIP} cmake variables
are currently set to values like CMAKE_LINKER-NOTFOUND for native
recipes because the host paths are not searched. This is because the
CMAKE_FIND_ROOT_PATH_MODE_PROGRAM cmake variable is set to ONLY.
To resolve this, explicitly set the variables using FIND_PROGRAM and
pass the CMAKE_FIND_ROOT_PATH_BOTH option so the host paths are also
searched.
Can you please debug the issue. Regarding my current check the
variables are set in CMakeFindBinUtils.cmake and this is included by
CMakeDetermineCCompiler.cmake. The later set
_CMAKE_TOOLCHAIN_LOCATION based on the CMAKE_C_COMPILER variable and
this is used as search location for the find_program calls. Can you
check the value of _CMAKE_TOOLCHAIN_LOCATION?
Within the context of the CMakeLists.txt file:
CMAKE_C_COMPILER is /usr/bin/gcc.
_CMAKE_TOOLCHAIN_LOCATION is not set to anything.
If I add message(test) to
build/tmp/sysroots/x86_64-linux/usr/share/cmake-2.8/Modules/CMakeDetermineCCompiler.cmake,
it doesn't get printed out when running cmake on CMakeLists.txt (cmake
is build/tmp/sysroots/x86_64-linux/usr/bin/cmake).

For:
find_program(CMAKE_AR NAMES
${_CMAKE_TOOLCHAIN_PREFIX}ar${_CMAKE_TOOLCHAIN_SUFFIX} HINTS
${_CMAKE_TOOLCHAIN_LOCATION})
It seems the ${_CMAKE_TOOLCHAIN_LOCATION} hint is not used when
CMAKE_FIND_ROOT_PATH_MODE_PROGRAM is set to ONLY.
Test case (CMakeLists.txt):
cmake_minimum_required(VERSION 2.8)
set(CMAKE_FIND_ROOT_PATH /var/empty)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)
FIND_PROGRAM(LD NAMES ld HINTS /usr/bin)
message(${LD})
Running cmake displays:
LD-NOTFOUND
If "set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)" is commented out, it
displays /usr/bin/ld.
Regards,
Jonathan
