Re: [CMake] cmake create executable Undefined symbols for architecture x86_64:

[Sean Wayland]

Thanks Micha,
The head developer managed to get it to compile under clion on the
weekend, I suspect he may have cleaned up his source code a little
bit. I also suspect listing the source code and targeted libraries in
the correct order may have helped. Thanks for all your help!
Best Sean

Re: [CMake] cmake create executable Undefined symbols for architecture x86_64:

[Sean Wayland]

Hi Micha,
Thanks very much for the email. That seemed to make a small
difference! With both those lines commented out these errors are
generated ( below my email ) .
I still have included
project(CATSMAT)
at the top line of the cmake file in the catsmat directory

I tried commenting out each of those language type definitions
separately but it didn't seem to help.
The code compiles under xcode. Those language types ( C++14) are
specified in Xcode so I was trying to find a way to copy what is in
xcode.

Is there a maximum number of "errors" before the clion compiler will
spit the dummy ?

Another executable will compile with lots and lots of warnings but no "errors"

I don't know much about C++ unfortunately. These errors look like
simple errors which I could see might be generated if the syntax of
the language had changed slightly from one version to the next ..

Thanks for you help!

Sean

Hi Micha,
Thanks very much I tried that .. I added it to the application
directory cmakelists.txt file . Same issue .. It's already in the top
level cmake file which looks like this ..

project(CATSMAT)
cmake_minimum_required(VERSION 3.6.3)


if (APPLE)

set(CMAKE_C++_FLAGS -mmacosx-version-min=10.4)
endif (APPLE)


include_directories("catsmat/libIMUSANT")

add_subdirectory (catsmat/googletest-master/googletest)
add_subdirectory (catsmat/libMusicXMLv3/libmusicxml-3.00-src/cmake)
add_subdirectory (catsmat/libIMUSANT/cmake)
add_subdirectory (catsmat/libIMUSANT_Tests/cmake)
add_subdirectory (catsmat/catsmat/cmake)

set(CMAKE_CXX_STANDARD 14)
