XCode build failed

[francoisreme]

Hi Matthiew.

I'm trying to build AudioTK on XCode.

I installed Boost, libsndfile et fftw via macports and the CMake generation process seem to work more or less, except for FFTW but I tried to run a build and hoped to see work not every module but at least get ATK Core to build.

My cmake output is :

_INFO Build shared libraries: ON
INFO Build static libraries: OFF
INFO Build tests: ON
Could NOT find FFTW (missing: FFTW_LIBRARY_FFTW3 FFTW_LIBRARY_FFTW3F FFTW_LIBRARIES FFTW_INCLUDES)

the build fails in TypedBaseFilter.cpp and there was to issue there :
At first in the with RValue constructor
template<typename DataType> TypedBaseFilter<DataType>::TypedBaseFilter(TypedBaseFilter&& other) :Parent(static_cast<Parent &&>(std::move(other))),

There was an error if I was not casting std::move(other) to RValue type.

I confess I'm not fluent at all with C++11 Feature and I'm lost there.

I hope you have a OS X and you could try a build on your machine, or maybe you got an idea of what's happenning ?

I'm on OS X El-Capitain. I use LLVM.

Thank you

By default, C++11 is not activated on the main compilers used by the users (although it starts coming with VS and GCC6).
In your case, you need to add -std=c++11 to the CMAKE_CXX_FLAGS and that should do the trick ;)

[francoisreme]

Thank you Matthiew ! I was this I had to enable C++ 11 option on every subtarget.
Strangely it's a custom post build who fails now : And builds fails after ATKCore !

That's annoying... There may be an issue with the dependency ordering at the moment. Is the file available in the build folder /Users/francoisreme/Project\ From\ Internet/AudioTK/build/ATK/Core?

Here come the content of the generated Core directory :

Sorry, the file is there but there is only an issue about his location !

[mbrucher]

I see, it's in the subfolder.
Well, I'll have to have a closer look later next week, I'm too busy to fix the issue in the next few days :/
What you can do is either use a release build, or you can change the main CMakeLists.txt to add Debug in the dsym working folder :/

[francoisreme]

Changing in main CMakeList to :
POST_BUILD
COMMAND dsymutil Debug/$<TARGET_FILE_NAME:${target}>
Works like a charm. Thank you for you help, I will now be able to perform tests !

Thanks !

[mbrucher]

Really strange, I can't reproduce the issue. Maybe because my xcode project lived through several CMake versions :/ I'll have to start from scratch one day :/

[mbrucher]

Oh!
You may have had CMAKE_BUILD_TYPE set to empty or not defined?

[francoisreme]

Yes, it's empty...and that's cool ?

[mbrucher]

It should be set to Debug or Release, depending on your build. That must be why you have that error.

[francoisreme]

Ok. It's works. I think there is a better way to handle this with CMake.
I mean because this kind of exe location path changes might depend from configuration, and can't be static on cmake configuration time (it's make "useless" the configuration thing of CMake)

I personnaly use the $<TARGET_FILE:tgt> command who work pretty well :
https://cmake.org/cmake/help/v3.0/manual/cmake-generator-expressions.7.html
(I have probleme to format the < on github using \ or not)
Cheers :-)
