This is not a bug, I think. Just requires to specify additional options for proper cross-compiling.

I'm not trying to cross-compile. I'm building an x86 lldb on x86 Windows. Are you saying there's some flag I need to pass for this?

This worked before and doesn't anymore, so seems like a bug to me.

Setting CMAKE_SYSTEM_PROCESSOR to X86 explicitly should help in this case, but it is rather a temporary workaround.

It seems like a CMake bug which has not been fixed yet: https://gitlab.kitware.com/cmake/cmake/issues/15170

[labath]

So, what the linux versions of these files do, is they list all files unconditionally in cmake, but then the entire contents of the files is wrapped in "#ifdef ARCH". It's not the most principled solution, but it's probably more robust...

[zmodem]

Building with -DCMAKE_SYSTEM_PROCESSOR="X86" works for me, so that unblocks the release.

labath's suggestion in #​5 sounds like a good idea though. Is anyone implementing it?

I spoke too soon. Turns out my build worked because I had commented out the part that checked out lldb. In fact, the build fails with the same error.

This means rc1 is shipping without lldb binaries for Windows.

[tkrasnukha]

Did you also set CMAKE_SYSTEM_NAME to Windows? As I understand, this option is required too. This is also important to clean the build directory (or at least, to delete CMakeCache).

I'm going to.

I tried that last night. Cmake now goes down the cross-compilation path and fails because it's not passing -DPYTHON_HOME and -DPYTHON_EXECUTABLE to the sub-build (see below).

I think it was a mistake that r365155 wasn't reverted immediately when this problem came up, but since it seems we have a fix in progress I'm willing to wait another couple of days.

Hans, I am not sure if you were following along, but I believe r367414 is supposed to have fixed this problem.

Seems to be working. Thanks everyone!

I've merged it to release_90 in r367523.
