Re: Problem sending double with GDbus

[elboulangero <elboulangero gmail com>]

Hi,
I'm facing the same problem, which version of glib are you using ? I'm using
the 2.28.8, and I'm working on embedded ARM device.

I tried to run the test gdbus-serialization, first on my computer (x86_64)
and there is no problem.
Then I run it on the target I'm working on (armv5tejl), and I got this
result :

ERROR:gdbus-serialization.c:600:check_serialization: assertion failed (s ==
expected_dbus_1_output):
value 0:   string: `this is a string'
value 1:   object_path: `/this/is/a/path'
value 2:   signature: `sad'
value 3:   byte: 0x2a
value 4:   bool: true
value 5:   int16: -42
value 6:   uint16: 60000
value 7:   int32: -44
value 8:   uint32: 100000
value 9:   int64: -34359738368
value 10:   uint64: -1
value 11:   double: 7.521667
==
value 0:   string: `this is a string'
value 1:   object_path: `/this/is/a/path'
value 2:   signature: `sad'
value 3:   byte: 0x2a
value 4:   bool: true
value 5:   int16: -42
value 6:   uint16: 60000
value 7:   int32: -44
value 8:   uint32: 100000
value 9:   int64: -34359738368
value 10:   uint64: 18446744073709551615
value 11:   double: 42.500000


We can see the value 10 and 11 are wrong.

Regards,
