Oh, sorry, I missed the attachments in the previous email. Here we have the
likely problem: you're running GCC 4.1. That's not supported, it's too old. At
least 4.2 is necessary, and that's for Mac OS X's sake.
I highly recommend you upgrade, to at least 4.4. I do notice that you're
running RHEL 5 and, given the kernel's compilation date, you're still getting
updates. In turn, I must conclude that RH is not giving updates on the
compiler. That's unfortunate.
Still, can you try changing the line in question to be:
static const TestData inNativeEndian = { Q_UINT64_C(0x0123456789abcdef),
0x00c0ffee, 0xcafe, 0xcf, '\0' };
Yes, that does allow it to compile.
If that works, we should apply the fix. It's the right thing to do anyway.
If it doesn't, I'm not sure we should do anything, actually. This is a unit
test and I don't expect anyone to be concerned about running the tests with
GCC 4.1. Aside from miscompilation issues, the result of the tests is the same
no matter what compiler you use.
