nativesdk-qtbase 5.9.2 C++11 errors with gcc 6.3?

nativesdk-qtbase 5.9.2 C++11 errors with gcc 6.3?

[Denys Dmytriyenko]

Martin, Khem,

Have you tried building Qt 5.9 with gcc 6.3 from oe-core? I'm seeing bunch of 
what seems to be C++11 related errors during do_configure of nativesdk-qtbase. 
Target qtbase builds fine and switching to gcc 7.2 seems to resolve it as well.

Any ideas or pointers? Thanks!

Re: nativesdk-qtbase 5.9.2 C++11 errors with gcc 6.3?

[Denys Dmytriyenko]

Khem,

I tried following on your suggestion to add #include <cmath>, but it is 
already there in src/corelib/global/qnumeric_p.h

Not sure why target qtbase builds fine with oe-core gcc 6.3.0, but 
nativesdk-qtbase fails with this error... Any more ideas? Thanks.

Do you use uninative ? if not then try with uninative. 
It seems to be mixing headers from your build host and nativesdk sysroot
there could be several reasons for that. You can also try to build on
a different distro on host may be one which has gcc6 as host gcc.

[Tim Orling]

Or use one of the CROPS docker containers with gcc6

Tried uninative - didn't help, same issue.

I'm not so sure host headers are getting in the mix - it's Ubuntu 16.04 with 
gcc 5.4 on it, while switching between gcc 6.3 and gcc 7.2 in oe-core/master 
works with 7.2, but not 6.3.

I can see if I can try on a host with gcc 6...

So, it does look like a host contamination in Ubuntu 16.04 with gcc 5.4.
But why didn't uninative help?

And gcc 6.4 from 2 patches above didn't help on Ubuntu 16.04...

I'm getting the same error when building qemu 2.8.0 for intel-corei7-64 
with gcc 6.3.0.

The reason seems to be that somewhere there's a
  #define isnan __builtin_isnan
which doesn't work in C++ because std::__builtin_isnan    does not
exist.

I'm still looking for the define... if someone has suggestions, I'm all
ears.

Seems to be from /usr/include/math.h, which gets included by the
corresponding C++ header /usr/include/c++/6.3.0/cmath.

C++ explicitly states that cmath exposes functionality of math.h inside
the std namespace (https://stackoverflow.com/questions/32606023/when-us
ing-c-headers-in-c-should-we-use-functions-from-std-or-the-global-na),
so the QEMU code is correct.

To me this is starting to look like a bug in the toolchain.
