Build error for fletch/Qt on MacOS 10.15

[eclairamb]

Hi,
I'm facing issues trying to build VIAME on MacOS 10.15. In fletch build step, Qt Configure step raises the following compilation error :

Creating qmake. Please wait...
clang: warning: include path for libstdc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead [-Wstdlibcxx-not-found]

Here is my cmake command :

Force to use -stdlib=libc++" option on this platform. I'm using clang compiler.

It seems that qmake is not aware of CXX_FLAGS ...

Could you please help me, I have to build VIAME on this platform to be used by an interesting project about shark underwater recognition.
Many thanks for your help.

Eric.

Hi, Sorry for the delay .. I was trying to reproduce this issue on the Mac I have but needed to overcome a few other Qt build issues first. I'm a little confused by the issue as written up. Can you explain why you need to pass *-DCMAKE_CXX_FLAGS:STRING='-stdlib=libc++'*? Is this an issue building Fletch alone or something to do with the VIAME superbuild? I am able to build Fletch's Qt on my mac without passing any flags into CMake. It does require #683, but that patch has nothing to do with this issue. My Mac is a bit older though, ProductVersion: 10.15.7. If you could try building Fletch with that PR or wait a few days until it lands in master, and see if it works without any addition flags added. Ideally, just build Qt. You can configure all packages and `make -jxx Qt` to build it and its dependencies without other potentially problematic packages. Reporting back with those answers and results will help us diagnose the issue. if that works, it might have something to do with the VIAME superbuild rather than Fletch itself. In that case, @mattdawkins would be better able to assist. Thanks, Dave

Hi David ,

Thanks for your answer and sorry for this late one. I was a little bit out of the project for a time, but I'm now back.
I've successfully build Qt using "release" branch Fletch build yesterday without passing any specific flags into CMake. :-)

So, issue seems to be related to VIAME superbuild. I'm contacting @mattdawkins about it.

Thanks for your help,
Eric
