The toolchain was a great suggestion. I am still having problems, but at least I know I am using the right toolchain: Currently, this is what I have for my toolchain:
set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_PROCESSOR arm) set(TOOLCHAIN_PATH /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi) # where is the target environment set(CMAKE_FIND_ROOT_PATH /opt/toolchains/arm-2008q3/arm-none-linux-gnueabi) # specify the cross compiler set(CMAKE_CXX_COMPILER /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-g++) set(CMAKE_C_COMPILER /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-gcc) #set(CMAKE_AR /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-ar) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY) set(COMPILE_FLAGS "-lrt -Wall -lpthread") I run cmake with the reference to that toolchain file, cmake –DCMAKE_TOOLCHAIN_FILE=cmake/toolchain.cmake I can see it finds the right toolchain and compilers. Now I am having some issues where it is getting conflicted between using sys or linux headers…. Is this just a header issue? CMAKE question: What is the difference between the two variables? TOOLCHAIN_PATH CMAKE_FIND_ROOT_PATH Should they be the same reference location? This is the folder structure at the /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi /bin /include /lib /libc Thoughts? Thanks!

I personally use cmake with multiple cross toolchains successfully. I guess it depends on what you are trying to achieve. I prefer it because I can use the same CMakeLists.txt to build natively on linux/mac/windows, as well as cross-compile against an embedded arm linux. I'd also agree with the previous discussion about using a toolchain file for your platform, it does simplify things.
