Finally I took the time to write some documentation about how the assembler support in cmake works: http://www.cmake.org/Wiki/CMake/Assembler I think you should create an assembler "dialect" for sdcc, which handles assembler files appropriately. Please let me know if that helps, if there are things unclear or missing on the wiki page etc. Bye Alex ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake

I.e. enable_language(ASM...) I will have a closer look in the next days. You can have a look at the other assembler support files in CMake/Modules/. I guess we'll have to create a ASM_SDCC "language". Alex ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
Re: [CMake] Linking object files into executable target
I asked a similar question about a month ago. The response can be found in
the archive:
http://www.cmake.org/pipermail/cmake/2008-November/025541.html
I tried it on VS, and it seem to work (though I had to use .obj instead of
.o to make it work).
Perhaps you could take the response as a start and work back to your project
a little at a time.

I forgot to include the CMake/SDCC toolchain file I'm using, which
might be of help:
# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Generic)
# which compilers to use for C and C++
SET(CMAKE_C_COMPILER sdcc)

[CMake] Linking object files into executable target
I'm using CMake and SDCC to build a project for the 8051
microcontroller. CMake has been working great for this so far, but now
I need to link in an object file that I've assembled with SDCC's
"asx8051" assembler, and I am not able to get CMake to explicitly add
an object file to the list of objects to be linked into a target.
The problem is that CMake is *silently* ignoring the request to link the
object file into the executable target with ADD_EXECUTABLE().
First, I am using ADD_CUSTOM_COMMAND to assemble the assembly code into
an object file (".rel" extension, as are the object files produced by
SDCC for compiled C code). The custom command is resulting in the
object file being produced properly.
Next, my ADD_EXECUTABLE() call simply names the object file in addition
to the C source files that I already am specifying. However, while the
C source files are compiled and linked with into the target executable,
the '.rel' object file is not being added into the list of objects to
link into the executable.
I think that the GENERATED=TRUE and EXTERNAL_OBJECT=TRUE source
properties on the generated object file should cause CMake to link it.
Is there something I'm doing wrong?
Here's my CMakeLists.txt:
-
CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
PROJECT(timertest C)
SET(CMAKE_ASM_OUTPUT_EXTENSION ${CMAKE_C_OUTPUT_EXTENSION})
SET(MY_SRCS main.c)
SET(MY_ASM_SRCS sleep_timer_get.asm)
FOREACH(ASMFILE ${MY_ASM_SRCS})
GET_FILENAME_COMPONENT(BASENAME ${ASMFILE} NAME_WE)
SET(SRC ${CMAKE_CURRENT_SOURCE_DIR}/${ASMFILE})
SET(OBJ
${CMAKE_CURRENT_BINARY_DIR}/${BASENAME}${CMAKE_ASM_OUTPUT_EXTENSION})
SET_SOURCE_FILES_PROPERTIES(${OBJ} PROPERTIES
GENERATED TRUE
EXTERNAL_OBJECT TRUE)
ADD_CUSTOM_COMMAND(OUTPUT ${OBJ}
MAIN_DEPENDENCY ${SRC}
COMMAND asx8051-wrapper
ARGS -I${CMAKE_CURRENT_SOURCE_DIR}
-o ${OBJ} ${SRC})
LIST(APPEND MY_ASM_OBJS ${OBJ})
ENDFOREACH(ASMFILE ${MY_ASM_SRCS})
MESSAGE(STATUS "MY_ASM_OBJS is ${MY_ASM_OBJS}")
ADD_EXECUTABLE(timertest main.c ${MY_ASM_OBJS})
-
I have attached the output I get when I build using this file.
I have spent all day and most of the night trying to get this to work,
and I've already started working on a Makefile to replace CMake for
this, though I really would hate to give up CMake; however, this silent
failure by CMake is creating an impossible-to-track-down problem.
Thanks for any help.
