Hello all together!
Currently I am trying to get the ti-cgt 5.2.5 compiler working with CMake.
Therefore, I use the blinky sample project from TivaWare.
To keep it simple in a first try, I added all the original flags from the code composer project into a toolchain file:
#include(CMakeForceCompiler)
set(CMAKE_SYSTEM_NAME Generic)
set(COMPILER_PATH "C:/git/saveris/toolchains/") # TODO
set(TI_CGT_PATH "${COMPILER_PATH}/arm-ti-cgt-5.2.5")
# specify the cross compiler
SET(CMAKE_C_COMPILER ${TI_CGT_PATH}/bin/armcl.exe)
SET(CMAKE_CXX_COMPILER ${CMAKE_C_COMPILER})
SET(CMAKE_ASM_COMPILER ${TI_CGT_PATH}/bin/armasm.exe)
#ENABLE_LANGUAGE(ASM)
# skip compiler tests
set(CMAKE_ASM_COMPILER_WORKS 1)
set(CMAKE_C_COMPILER_WORKS 1)
set(CMAKE_CXX_COMPILER_WORKS 1)
set(CMAKE_DETERMINE_ASM_ABI_COMPILED 1)
set(CMAKE_DETERMINE_C_ABI_COMPILED 1)
set(CMAKE_DETERMINE_CXX_ABI_COMPILED 1)
# Add the default include and lib directories for tool chain
include_directories(${TI_CGT_PATH}/include)
link_directories(${TI_CGT_PATH}lib)
# set target environment
set(CMAKE_FIND_ROOT_PATH ${TI_CGT_PATH})
set(PLATFORM_CONFIG_C_FLAGS "-mv7M4 --code_state=16 --float_support=FPv4SPD16 --abi=eabi -me -O2 -g --include_path=C:/TI/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/include --include_path=C:/TI/TivaWare_C_Series-2.1.0.12573 --gcc --define=ccs=ccs --define=PART_TM4C1294NCPDT --diag_warning=225 --display_error_number --diag_wrap=off --gen_func_subsections=on --ual" CACHE STRING "platform config c flags")
# combine flags to C and C++ flags
SET(CMAKE_C_FLAGS "${PLATFORM_CONFIG_C_FLAGS} ${CMAKE_C_FLAGS}" CACHE STRING "platform config c flags")
SET(CMAKE_CXX_FLAGS "${PLATFORM_CONFIG_CXX_FLAGS} ${CMAKE_CXX_FLAGS}" CACHE STRING "platform config c flags")
SET(CMAKE_EXE_LINKER_FLAGS "-mv7M4 --code_state=16 --float_support=FPv4SPD16 --abi=eabi -me -O2 -g --define=ccs=\"ccs\" --define=PART_TM4C1294NCPDT --diag_warning=225 --display_error_number --diag_wrap=off --gen_func_subsections=on --ual -z --stack_size=256 -mblinky_ccs.map --heap_size=0 -iC:/TI/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/lib -iC:/TI/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/include --reread_libs --warn_sections --display_error_number --diag_wrap=off --xml_link_info=blinky_linkInfo.xml --rom_model" CACHE STRING "platform config linker exe files")
Then, when I run CMake and try to build it with make, I get this error:
<Linking>

I found out, that in the build.make file, there are some additional flags added to the call of the compiler (--run_linker….) that are not there in the makefile generated from code composer. “mv7M4” should be the first flag. When I remove the from CMake added flags in between “armcl.exe” and “mv7M4”, the errors disappear:
cd C:/git/saveris/build/none/debug/app/ethernet2cloud && C:/git/saveris/toolchains/arm-ti-cgt-5.2.5/bin/armcl.exe --run_linker --output_file=../../bin/ethernet2cloud --map_file=../../bin/ethernet2cloud.map --search_path=C:/git/saveris/toolchains/arm-ti-cgt-5.2.5lib -mv7M4 --code_state=16 --float_support=FPv4SPD16 --abi=eabi -me -O2 -g --define=ccs="ccs" --define=PART_TM4C1294NCPDT --diag_warning=225 --display_error_number --diag_wrap=off --gen_func_subsections=on --ual -z --stack_size=256 -mblinky_ccs.map --heap_size=0 -iC:/TI/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/lib -iC:/TI/ccsv6/tools/compiler/ti-cgt-arm_5.2.5/include --reread_libs --warn_sections --display_error_number --diag_wrap=off --xml_link_info=blinky_linkInfo.xml --rom_model $(ethernet2cloud_OBJECTS) $(ethernet2cloud_EXTERNAL_OBJECTS)
As a comparison, the flags when I use gcc:
cd C:/git/saveris/build/none/debug/app/ethernet2cloud && C:/git/saveris/toolchains/arm-none-eabi-gcc-4.8/bin/arm-none-eabi-gcc.exe -O0 -fprofile-arcs -ftest-coverage -g -gdwarf-2 -lgcov --coverage $(ethernet2cloud_OBJECTS) $(ethernet2cloud_EXTERNAL_OBJECTS) -o ../../bin/ethernet2cloud
My question is now: Do anyone ever try to use CMake with the TI compilers?
Has anyone over done similar experiences?
Thank you all for you answers
