Build issues with version 0.33 on Windows (0.32 works fine)

[MSoegtropIMC]

I just upgraded a meta project containing ott from version 0.32 to version 0.33. I am experiencing build issues on Windows which did not appear with 0.32.

The error is:

#=== ERROR while installing ott.0.33 ==========================================#
Some files in C:/bin/cygwin64_coq_platform/home/Michael/.opam/CP.2023.03.0~8.17~2023.03+beta1/.opam-switch/install/ott.install couldn't be installed:
  - C:/bin/cygwin64_coq_platform/home/Michael/.opam/CP.2023.03.0~8.17~2023.03+beta1/.opam-switch/build/ott.0.33/src/ott to C:/bin/cygwin64_coq_platform/home/Michael/.opam/CP.2023.03.0~8.17~2023.03+beta1/bin
  -

The reason that the ott binary cannot be copied to bin is that it is named ott.opt while install expected the name ott. The proper name on Windows would be ott.exe .

In version 0.32 the installed binary has the name ott.exe.

@palmskog : FYI

P.S.: I double checked that in exactly the same environment opam install ott.0.32 succeeds and opam install ott.0.33 fails.

I don't see any changes to the executable names between versions; it was ott.opt and opt in 0.32 too. I think it's more likely that the generation of ott.opt has failed. opam should tell you where to find a more complete log of the failed build, could you take a look at it?

[MSoegtropIMC]

The generated ott.opt file is there under src. Also opam says that the build step succeeded successfully - otherwise it would not even start the install step and the failure is in opam's install step.

Also with 0.32 the file ending up in the bin folder (=install target folder for the executable) is definitely named ott.exe (on Windows).

That's very strange - the build step should include copying the file, it's part of the make world. Does it tell you which commands make ran?
