Hi Mackie, I'll check it and let you know as soon as I have it.

Thanks for the report, makie.
I was able to reproduce the Makeobj build failure on both GCC and MSVC. It was a regression introduced in r12234: the headless

Code Select

image_t no longer contains

Code Select

len and

Code Select

zoomable, while Makeobj was still using an

Code Select

image_t instance as temporary writer state.
I have fixed this by keeping that metadata local to

Code Select

image_writer.cc, without adding anything back to the headless

Code Select

image_t.
The fix is now in trunk as r12235.
I also verified that Makeobj builds correctly again and that the generated

Code Select

.pak output is byte-identical to the pre-regression version.
