Hello,
Since the recent addition of resman.c and embedding of
graph.{html,css} some of the Windows builds fail. There seems to be a
regression in path joining, caused by \ / mismatch.
Generally those issues were never a problem and I would prefer to keep
it this way. This configuration has always been flaky and undertested.
I could set-up a pipeline to report to the fate server if that's
something that would help stabilize it.
Example of failure:
```
BIN2C fftoolsresourcesgraph.html.c
BIN2C fftools/resources/graph.html.c
SED fftoolsresourcesgraph.css.min
sed: can't read /c/a/FFmpeg/FFmpeg/fftoolsresources/graph.css: No such
file or directory
SED fftools/resources/graph.css.min
make: *** No rule to make target 'fftools\resources\graph.html.c',
needed by 'fftools/resources/graph.html.o'. Stop.
make: *** Waiting for unfinished jobs....
HOSTCC tests/videogen.o
rm fftools\resources\graph.css.min fftools/resources/graph.html.c
```
Note that BIN2C is called twice, once with the correct path and with
the wrong one.
Removing resman.c fixes the build. This has to be done forcefully in
the code, because there is no configure option to disable this
html/css embedding.
You can see the details and whole failing build logs here:
code: https://github.com/kasper93/FFmpeg/tree/gha
build:
https://github.com/kasper93/FFmpeg/actions/runs/15653223193/job/44100735119

--host_extralibs='' --toolchain=msvc && make -j`nproc` && make

fate
Here is exactly the same pipeline with removed graph.{html,css}
https://github.com/kasper93/FFmpeg/tree/gha2
https://github.com/kasper93/FFmpeg/actions/runs/15656127992
Builds just fine.
Ignore win32 (windows-11-arm, arm64, --toolchain=msvc) failure, as
this is affected by unrelated regression in dxvenc.c on arm64 target,
but the build itself is passing just fine.
Any ideas how we can restore the ability to build ffmpeg on Windows?
Thanks,
Kacper
