Yes, I saw that. I also tried to port changes at some point to newer gcc, but eventually I had problems with some dll's so I kept using older builds. > > Now, with WinPhone8 it rejects the libs as invalid.

Yes, it seems that WinPhone8 sdk uses almost identical build of cl for arm as Windows8 (only a couple of revisions different and some CRT quirks as usual). I tried to see why exiting pure arm libs from WinCE aren't acceptable by tools from WinPhone8 and it seems that the issue is only in that Machine type header: now it needs to be IMAGE_FILE_MACHINE_ARMNT (for Thumb-2, value is 0x01c4, not sure if it's already published) instead of IMAGE_FILE_MACHINE_ARM or IMAGE_FILE_MACHINE_THUMB. Otherwise, it's pretty much the same. So, cegcc tools could be patched to use different value for machine type and possibly it could be accepted by tools from WP8. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
