Custom C++ Toolchain

[Azrathud]

This is awesome, and I hope I'll be programming on Linux come next season.

I'm trying to set up this toolchain on a 64-bit install of Archlinux, and I'm getting some errors after

• Running the build script for downloading and patching gcc for vxworks
• Editing the toolchain(changing gccdist to true, setting deploy ip)
• Creating a CMakeLists.txt file based off your example
• Running cmake

Maybe this is something of note: while running

cmake /home/azrathud/vxworks-c++-toolchain/project -DCMAKE_TOOLCHAIN_FILE=/home/
azrathud/vxworks-c++-toolchain/cmake_vxworks/vxworks_toolchain.cmake

Cmake outputs that CMAKE_TOOLCHAIN_FILE is not used



I'm trying to compile last season's code which is in the src directory specified in the CMakeLists.txt

From the errors, I think gcc cannot find the header files in /usr/local/powerpc-wrs-vxworks/sys-include

I included what I pulled from your WPIlib github repo in the CMakeLists.txt locally, but I looks like from your cmake toolchain file, that I should be placing them in the place under /local .. include/WPILib, yes? Also, I added the sys-include to the list of includes, but it didn't look like it did anything to help.

cmake_minimum_required(VERSION 2.8)

project(FRC)

aux_source_directory(./src FRC_SOURCES) # I'll just run cmake all the time to
        # make sure new files are added

set(FRC_INCLUDES ${WPILIB_INCLUDE_DIR} wpilib ${TOOLCHAIN_PREFIX}/sys-include ) #defined by toolchain
set(FRC_LIBS ${WPILIB_LIBRARY}) # defined by toolchain

add_executable(FRC_UserProgram ${FRC_SOURCES})
set_target_properties(FRC_UserProgram PROPERTIES SUFFIX .out)
target_link_libraries(FRC_UserProgram ${FRC_LIBS})
include_directories(${FRC_INCLUDES})

I think the problem may relate to that I haven't compiled the wpilib into a shared library, like the toolchain suggests. (I have no ${TOOLCHAIN_PREFIX}/lib/libWPILib.a) How would I go about correctly including the patched WPILib and allow that to be linked correctly, etc?
