cargo-c v0.7.1+cargo-0.49: compiling fails (de.rs:530:63 - type annotations needed)

cargo-c issue 159 - suggested workaround: cargo install cargo-c --locked

ab-suite.rust.install.log

PS: cargo issue 9101 - may get fixed upstream soonish

Not sure that posting an issue due to an external dependency of a dependency is broken, but sure.
I tried running cargo install cargo-c --locked in the mintty environment but a different error came up.

You can still build FFmpeg but you need to explicitly disable the building aom, rav1e1, dav1d, and libavif=2 in build/media-autobuild_suite.ini and build/ffmpeg_options.txt. The names are different in in the build/ffmpeg_options.txt file, so here's how they map out:

library	media-autobuild_suite.ini	ffmpeg_options.txt
aom	set aom=2	change --enable-libaom to --disable-libaom
dav1d	set dav1d=2	change --enable-libdav1d to --disable-libdav1d
rav1e	set rav1e=2	change --enable-librav1e to --disable-librav1e
avif	set libavif=2	No changes needed

Then retry the build and cargo-c won't be a problem since it's only used to build the above libraries.

I mainly posted it to report that I already investigated a bit about the reason, and it is not the fault of the suite... so the main solution (if you want to build anything that depends on rust) is "patience".

This "different error" is an interesting one... essentially:

  = note: ld: cannot find -lntdll

cargo-c.install-locked.log

Maybe it requires custom directory variables.

Solved.
