[yocto] CMake project not building; building from local git repo possible

Tue May 30 02:28:40 PDT 2017

Hi Marek,

Thanks for your answer!
I did use a local repo folder since I find it more convenient to make 
quick changes that way, as it is the case right now.

I applied your changes but I still get the same bitbake errors as 
before, as shown below. The CMake Error log says:
...
error: unrecognized command line option '-Wmissing-variable-declarations'
...
error: unrecognized command line option '-Wshorten-64-to-32'
...

I tried to coment out the addition of the corresponding flags (in 
cmake/CFlags.cmake) with no improvement.

Now I compiled with another arm-gcc version (digi embedded version of 
arm-gcc, 6.2.0) and I get a different error -.- :
| DEBUG: Executing python function sysroot_cleansstate
| DEBUG: Python function sysroot_cleansstate finished
| DEBUG: Executing shell function do_configure
| CMake Error: The source directory 
"/home/jakob/workspace/newuvalue/tmp/work/cortexa7hf-neon-dey-linux-gnueabi/stlink/0.1-r0/git" 
does not appear to contain CMakeLists.txt.
| Specify --help for usage, or press the help button on the CMake GUI.
| WARNING: exit code 1 from a shell command.
| ERROR: Function failed: do_configure (log file is located at 
/home/jakob/workspace/newuvalue/tmp/work/cortexa7hf-neon-dey-linux-gnueabi/stlink/0.1-r0/temp/log.do_configure.3539)

I have no idea why, but in the original source folder the CMakeLists.txt 
is there...

Cheers,
Jakob
