How to create a CMakeLists.txt in order to compile a PNaCl program?

I have a PNaCl program that I'm trying to compile using CMake.

I included the following lines but doest not work at all:

# disable compiler detection
include(CMakeForceCompiler)
CMAKE_FORCE_C_COMPILER("${CMAKE_C_COMPILER}" Clang)
CMAKE_FORCE_CXX_COMPILER("${CMAKE_CXX_COMPILER}" Clang)

# specify cross-compilers
set(NACL_BIN /usr/local/share/nacl_sdk/pepper_43/toolchain/mac_pnacl/bin)
set(CMAKE_C_COMPILER "${NACL_BIN}/pnacl-clang" CACHE PATH "gcc" FORCE)
set(CMAKE_CXX_COMPILER "${NACL_BIN}/pnacl-clang++" CACHE PATH "g++" FORCE)
set(CMAKE_AR "${NACL_BIN}/pnacl-ar" CACHE PATH "archive" FORCE)
set(CMAKE_LINKER "${NACL_BIN}/pnacl-clang++" CACHE PATH "linker" FORCE)
set(CMAKE_RANLIB "${NACL_BIN}/pnacl-ranlib" CACHE PATH "ranlib" FORCE)

Error printing: pnacl-ld: Unrecognized option: -search_paths_first

Solution

  • Based on Derek's answer: set(CMAKE_SYSTEM_NAME "Generic" CACHE STRING "Target system.")

    Otherwise, CMAKE will use specific flag.
