Re: [CMake] add_library without source code

Is there any way to get that work, without creating a dummy source file? AFAIK no. If you want, you can create that dummy file e.g. with file(WRITE ...), so it doesn't have to go into version control. lib1 and lib2 are shared libs, right ? Alex No they are static libraries. I recognized that i have the same problem with add_executable, there is also at least one source file necessary and i don't like to make dummy files for nothing. But maybe the configuration of my build is unusual for CMake. I've configured them like in my old Make Projects: I organize different software modules in subdirectories, so i have e.g. /modul1/modul1.c /modul1/CMakelists.txt /modul2/modul2.c /modul2/CMakelists.txt /CMakelists.txt The CMakelists is in the project root directory and adds the subdirectories (there are also CMakeLists.txt in the subdirectories) In the Subdirectories, I make libraries (e.g. add_library(modul1 modul1.c)), and in the root directory i'd like to link all libraries to a big library or to a executable. I tried to use add_library only with the library name and too use target_link_libraries to add the libraries of the su-modules, which didn't work. I don't like to have source files in the root directory, so i don't have source files for the commands add_library or add_executable in the root CMakeLists.txt file. How is somethiong like that usually done with CMake?

I'd like to use the Softune toolchain (for Fujitsu Microcontrollers), and the librarian
can only add object files to an library with the "-a" command line option. All
object files must have that flag. It could be done with wrapper shell scripts, but shells
are platform specific and so it's for me a no go. It's no problem if you use only one
build plattform, but if not so, you would have to write several shell scripts, or add the
shell executable for each build plattform.
I've already put it in as a feature request yesterday
(http://public.kitware.com/Bug/view.php?id=10588)
I also want to use Keil Compiler with CMake, but i would also need wrapper
scripts for the compiler, librarian and linker, because of the non standard way
of command line options. (It uses brackets, something like: cc
-o{obj1.o,obj2.o,...})
It would be nice to have the latter approach of my feature request (with
regular expressions), because it would be highly customizable. Someone could
even change slashes to backslashes, which could be handy if a windows tool is
used within cygwin or msys, which requires backslashes (slashes are standard on
cygwin or msys).
Matthias.
You don't have to use shell wrapper scripts. CMake is a portable (rather
quirky) scripting language ;-) I often do something like this:
add_custom_command(OUTPUT something
COMMAND "${CMAKE_COMMAND}" -DSOME=VALUE -P
"${CMAKE_CURRENT_BINARY_DIR}/some_configured_script.cmake"
DEPENDS "${CMAKE_CURRENT_BINARY_DIR}/some_configured_script.cmake"
WORKING_DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}"
COMMENT "Doing something incredibly smart"
VERBATIM
)
You can also modify CMAKE__CREATE_STATIC_LIBRARY to suit your needs,
perhaps something like this:
set(CMAKE_C_CREATE_STATIC_LIBRARY
"${CMAKE_COMMAND} -DOBJECTS=\"\" -DLIBRARY=\"\" -P
${CMAKE_BINARY_DIR}/create_archive.cmake")
where create_archive.cmake is configured to contain the full path to the
librarian tool (using @ONLY) and perhaps with other things. E.g.
create_archive.cmake.in might contain (untested):
set(ARGS)
foreach(o IN LISTS OBJECTS)
set(ARGS "${ARGS} -a ${o}")
endforeach()
set(ARGS "${ARGS} ${LIBRARY}")
execute_process(
COMMAND "@LIBRARIAN_EXECUTABLE@" ${ARGS}
RESULT_VARIABLE RES
OUTPUT_VARIABLE OUT
ERROR_VARIABLE OUT)
if(RES)
message(FATAL_ERROR "@LIBRARIAN_EXECUTABLE@ failed to create archive
${LIBRARY}."
"The output message was\n"
"${OUT}")
endif()
I tried that, and could get it working. I needed seperate_arguments to
get a list of the objects and had to remove the quotes, so that every
option was a list element. Otherwise it didn't work.
It's not very compfortable (you need a seperate cmake file, and you must
be careful with the quotes), but it doesn't depend on the platform and
it works. :)
Thanks,
Matthias.

[CMake] Slash, Backslash trouble with MSYS and Windows Compiler/Linker
Hello!
I`m using the Softune-Compiler under CMake with MSYS on Windows. (I'v e
written the Plattform files by myself)
The Softune Compiler (For Fujitsu Microcontrollers) requires Backslashes
for paths in the options, but Cmake generates slashes as it is usual in
MSYS.
e.g.
The linker must be called:
flnk907s -cpu MB90F345 -a -o otuput.abs main.o -l mylibrary\mylibrary.a
(it finds the library in the directory mylibrary)
but it is called like this
flnk907s -cpu MB90F345 -a -o output.abs main.o -l mylibrary/mylibrary.a
(it doesn't find the library in the directory mylibrary)
Is there any option to change the slashes with cmake to backslashes?
---
My Plattform file for the compiler looks like this:
MESSAGE(STATUS "Fujitsu_16LX-fcc907s.cmake loaded")
# This file implements support for the Softune Compiler

Another question: Are such plattform ports welcome in the cmake
distribution? If yes, I'll put it in as feature request, when my port is
functional.
BTW: Are there any naming conventions for new plattforms?
Cheers,
Matthias.

Yes, I tried that. Just for reference, my plattform file looks like this:

Without the -cpu option, the assembler can't assemble a file. So i tried
to set the flags within the INIT-Variables, but when i run make (I use
MSYS Makefiles), the assembler is called without the -cpu command line
option (snipped of the output of make VERBOSE=1):
cd /C/Projekte/Software/Gen/Src/Processor &&
/C/Projekte/Tools/Softune/V30/bin/FASM907S.EXE

[CMake] Lint Integration
Hi,
I´d like to integrate PC-Lint (www.gimpel.com, a source code checker for
C/C++) to my cmake build system
(Cross-Compile for an embedded Power PC with WindRiver Compiler, which is
running on Windows).
My first idea was to add a command to CMAKE_C_COMPILE_OBJECT, but I don't
know how to extract the include and definition command line options from
or .:
SET(CMAKE_C_COMPILE_OBJECT
" -Wa,-l -o -c
"
"${PCLINT_EXECUTABLE} +v -iC:\Lint std.lint )
How could i do this (is there a possibility to make string manipulation?),
or is there an other way to integrate lint?
PC-Lint should check each c-File, which is compiled by the Compiler.
Thanks a lot
