Hello,
I have built RTEMS 5 and its tools for the Xilinx Zynq Zedboard and installed
the BSP and tools at a certain position on my machine.
The tools are added to the PATH variable and RTEMS_BSPS is also available in
the environment.
Now we need to build a library for the use with RTEMS via CMake.
For this we wanted to use the toolchain files.
Does anybody know how to correctly setup such a toolchain file using the RTEMS
compiler?
We managed to get a toolchain file working which at least built the library.
But when we wanted to link to this library during compilation of a RTEMS
application we got a bunch of errors due to undefined references to standard
library functions.
Does anybody has a clue where this might origin from?
Building a RTEMS application which does not use the own library works fine.
Our toolchain file looks like this:
# CMake toolchain file for ARM
# The compiler is based on
# The RTEMS_BSPS environment variable is expected to be set.
set(ARCH arm)
set(CMAKE_SYSTEM_NAME RTEMS5)
set(CMAKE_CXX_FLAGS "" CACHE STRING "ARM RTEMS5 gcc additional compiler flags"
FORCE)
set(RTEMS_TOOLS_PATH $ENV{RTEMS_BSPS}/../../tools/bin)
set(CMAKE_C_COMPILER ${RTEMS_TOOLS_PATH}/arm-rtems5-gcc CACHE PATH "ARM RTEMS5
gcc" FORCE)
set(CMAKE_CXX_COMPILER ${RTEMS_TOOLS_PATH}/arm-rtems5-gcc CACHE PATH "ARM

set(CMAKE_CXX_COMPILER_AR ${RTEMS_TOOLS_PATH}/arm-rtems5-gcc-ar CACHE PATH "ARM
