Hi!
I'm just playing around with cmake for a new embedded project using a
STM32 ARM Cortex-M3 processor.
I have installed cmake 2.6.0-patch 2 from the cygwin distribution and
use a windows gcc toolchain from www.codesourcery.com.
After reading the manual and FAQ, i created a CodeSourcery.cmake file:
# the name of the target operating system
#
set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_VERSION 1)
set(CMAKE_SYSTEM_PROCESSOR arm-eabi)
# which compilers to use for C and C++
#
set(CMAKE_C_COMPILER arm-none-eabi-gcc)
set(CMAKE_CXX_COMPILER arm-none-eabi-g++)
# adjust the default behaviour of the FIND_XXX() commands:
# search headers and libraries in the target environment,
# search programs in the host environment
#
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
and a CMakeLists.txt in my project directory:
project(STM32 C)
cmake_minimum_required(VERSION 2.6)
set(CMAKE_TOOLCHAIN_FILE CodeSourcery.cmake)
set(COMPILE_DEFINITIONS_DEBUG -O0 -g3 -DDEBUG)
set(COMPILE_DEFINITIONS_RELEASE -O2)
add_definitions(
-Wall
-Wshadow
-Wcast-qual
-Wwrite-strings
-Winline
-std=gnu99
-DSTM32F10X_HD # for peripheral library
-DUSE_STDPERIPH_DRIVER
-DGCC_ARMCM3 # for FreeRTOS
)
include_directories(
${STM32_SOURCE_DIR}/.
${STM32_SOURCE_DIR}/fwlib
${STM32_SOURCE_DIR}/fwlib/inc
${STM32_SOURCE_DIR}/FreeRTOS/Source/include
)
link_directories(
${STM32_BINARY_DIR}/fwlib
)
add_executable(stm32test
bigfont.c
bitmap.c
enc28j60.c
graphics.c
lcd7565.c
main.c
syscalls.c
sysfont.c
systick.c
uart.c
)
target_link_libraries(stm32test libstm32fw.a)
...
The problem is: It doesn't work:
$ cmake -DCMAKE_TOOLCHAIN_FILE=CodeSourcery.cmake .

cmake tries to use cygwin-style absolute "/home/tkindler.." paths, which
arm-none-eabi-gcc doesn't seem to like (being a native win32 program).
My old makefile used relative paths to invoke the compiler. How can I do
this in cmake generated makefiles?!
Prepending "c:/cygwin/" to all paths should also solve the problem.
greetings,
