Hi All,
Could qt4.8 build on mips 64 bits platform?
I searched qt-project.org and no such related information.
And then grep the source codethat no such mips64 keyword in file
qmake.conf under directory mkspecs. In contrast there are mips32 related
flags in mkspecs/qws/linux-mips-g++/qmake.conf.
Does that mean we still can't build qt 4.8 on mips64?
Thanks a lot.

I don't have any specific knowledge here; I'd suggest trying it. If additional
patches are needed the best thing would be to try and get those merged
upstream.
Cheers,

Thanks a lot. I'll try to build it on mips 64.

The background here is that we encountered many painful build problems
with qt-4.7 on mips64 in oe-core-1.2. We tried to fix them initially
but investigations from 6 months ago indicated that the qt upstream
did not support mips64. Kai will dig into the current situation
but I expect that little will have changed.
We ended up with horrid bbapends such as:
---
#Valid for all arches except mips64 with 64bit userspace
# mips64 with n32 has host: mips64-wrs-linux-gnun32
# mips64 with n64 has host: mips64-wrsmllib64-linux
# qemumips has host: mips-wrs-linux
# qemumips-64 has host: mips64-wrs-linux
COMPATIBLE_HOST =
'((x86_64.*|i.86.*|powerpc.*|arm.*|mips-.*|mips32.*)-linux|mips64.*-linux-gnun32)'
---
so we'll likely need a clue on how to declare a host as incompatible
or introduce an INCOMPATIBLE_HOST variable.

I suspect something like this should work:
COMPATIBLE_HOST_mips64 = ""

Thanks.
We still need include such packages on mips64 with 32 bits filesystem.
So the following is needed:
COMPATIBLE_HOST_mips64 = "mips64.*-linux-gnun32"
I am little worried that "-gnun32" is a standard name then I'll figure it out.
