no spaces allowed in folder names in project path

[poramasionwu]

The project fails to compile if there are spaces in any of the folder names leading to the build folder...

example: if try the make command in the folder "my arduino project/build", I get errors

Hi, could you please provide an example of your configuration.

@naismith15 : I just found arduino-cmake and am having fun with it - I saw your comment I thought I would try to reproduce your problem.

Something that gets me occasionally with CMake is that you need to quote file names with spaces or some punctuation - this is not unique to arduino-cmake.

I made a simple 'blinky light' project in a folder with a space in the name and a source file also with spaces in the name and it builds fine for me.

eg: this is my CMakeLists.txt and it is in a folder named test blink; note the quoted file in the SRCS section generate_arduino_firmware(testblink SRCS testblink.cpp "source with spaces.cpp" PORT /dev/ttyACM1 SERIAL "microcom -p @INPUT_PORT@ -s 57600" BOARD ethernet) My platform is linux, hope this helps...

I'm on Ubuntu 12.04.

I may just be missing the correct punctuation, I'm still new to cmake. My folder name is: test cmake

The error I get is:

    ~/arduino_projects/projects/test cmake/example/Blink/Blink.ino:8:20: fatal error: config.h: No such file or directory

my CMakeLists.txt is as follows:

    set(CMAKE_TOOLCHAIN_FILE ${CMAKE_SOURCE_DIR}/cmake/ArduinoToolchain.cmake)
    cmake_minimum_required(VERSION 2.8)
    #====================================================================#
    #  Setup Project                                                     #
    #====================================================================#
    project("test cmake" C CXX)
    print_board_list()
    print_programmer_list()
    add_subdirectory(example)   #add the example directory into build

[HappyHeyoka]

what this does: add_subdirectory(example) #add the example directory into build is direct CMake to process another CMakeLists.txt file in a subdirectory example

What is the content of that file and what source/headers are in that subdirectory...?

[poramasionwu]

I'm basically just running queezy's project and following his readme. So the other CMakeLists.txt essentially looks like as shown in:

https://github.com/queezythegreat/arduino-cmake/blob/master/example/CMakeLists.txt

Ok, I'm about stumped - not exactly a CMake expert and only a week into using arduino-cmake :-( So, last suggestions:

• you obviously moved the example out of the original hierarchy... so the path for the toolchain stuff is good?
• did you remember to movie the 'config.h' file? (yeah, I know, but had to ask)
• I put my simple project in a repository called 'test-blink'... try that and see how you go (better or worse...)

Hi,

Sorry for responding so slowly, I've been a little bit busy. So I have tried to reproduce your problem, and I think I've reproduced it, although I got a different error. Here is what I did:

mkdir -p "dev/path with spaces"
cd "dev/path with spaces"

git clone git://github.com/queezythegreat/arduino-cmake.git
cd arduino-cmake

mkdir build
cd build

cmake ..
make

Configuration of the project worked as a charm, no errors. Building of the Arduino libraries worked without any errors. As the first firmware image was being built I got the error you describe:

-- The C compiler identification is GNU 4.7.0
-- The CXX compiler identification is GNU 4.7.0

I'm assuming that the error I got is the same as yours.

The error stems from the improper way the compiler options where being generated. I have fixed the problem, and the new version of arduino-cmake should be availabe under the develop branch.

Could you please confirm that this fiexes your problem.
