 #error Target architecture was not detected as supported by Double-Conversion.

Tried to compile with 'QT5BASE_CONFIGURE_OPTS += -no-doubleconversion', but gives:

Qt Core:
  DoubleConversion ....................... no
    Using system DoubleConversion ........ no

[...]

ERROR: Your C library does not provide sscanf_l or snprintf_l.
You need to use libdouble-conversion for double/string conversion.

Disable BR2_PACKAGE_QT5_VERSION_LATEST for xtensa (or xtensa/uClibc combination)?


Similare failure for arc:

Or add support to the double-conversion code?

For example, m68k support was contributed upstream:

  https://github.com/google/double-conversion/commit/da11179623145f53b204105a93b8bbca431141da

But indeed, for the release, disabling unsupported architectures is
probably best. Can you send a patch?

Thanks,

Thomas

Same for nios2:

Seems simple ;-), but I think it should be done by someone with access to the target arch who can
run the double-conversion test suite...

Can do..., depending on BR2_xtensa or (BR2_xtensa && BR2_TOOLCHAIN_USES_UCLIBC)?

Is it C library specific? I don't think it is.

Also, it's not only xtensa, but also arc and nios2 (at least).

This can be fixed by adding the following two lines to package/libv4l/libv4l.mk:

LIBV4L_CONF_ENV += CXXFLAGS="$(TARGET_CXXFLAGS) -std=gnu++0x"
LIBV4L_CONF_ENV += LDFLAGS="$(TARGET_LDFLAGS) -latomic"

This forces the same compile/link flags as would be used when (successfully)
compiling using the libv4l-1.12.2/utils/qv4l2/qv4l2.pro file...

I am not sure if this is a feasible solution? And when yes on which config
parameters this additional compile/link flags should depend?


ifeq ($(BR2_TOOLCHAIN_GCC_AT_LEAST_4_8)$(BR2_PACKAGE_QT5_VERSION_5_6),yy)
LIBV4L_CONF_ENV += CXXFLAGS="$(TARGET_CXXFLAGS) -std=gnu++0x"
ifeq ($(BR2_TOOLCHAIN_HAS_LIBATOMIC),y)
LIBV4L_CONF_ENV += LDFLAGS="$(TARGET_LDFLAGS) -latomic"
endif
endif


Regards,
Peter

This normally indicates that a dependency on BR2_TOOLCHAIN_HAS_SYNC_4
is missing.

Hum, so using gnu++0x forces to use __atomic built-ins instead of
__sync built-ins ?

Yes, seems so (and is the same as is done when configuring via qmake)...
