opam 2.2.0 beta1 compile and install old ocaml version(4.11.0) failed on windows. #5873

Open fenginsc opened 6 months ago

fenginsc commented 6 months ago

I'm trying to use the latest opam 2.2.0 beta1 and have successfully installed ocaml 5.0.0 and ocaml 5.1.0. The repository https://github.com/dra27/opam-repository#windows-5.0 is used. I also tried using the https://github.com/fdopen/opam-repository-mingw.git#opam2 repository and successfully compiled and installed ocaml version 4.12.0 - 4.14.0. But I failed to compile and install an older version of ocaml 4.11.0, is this normal? Or am I missing some installation dependency?

>opam switch create ocaml.4.11.0 --package=ocaml-variants.4.11.0+mingw64

If opam 2.2.0 is officially released is there no need for these third party repositories? Then it seems will be easier to install and use ocaml on windows in the future!

Can you show the full error message (from the file in C:\Users\<your username>\AppData\Local\opam\log\ocaml-variants-7884-26640c.out) ?

Otherwise I'm not sure what is the state of the pre 4.12 compilers in the temporary repositories. cc @dra27

Yes, the work to make the default opam-repository compatible is ongoing and there will indeed be no need for external repositories once 2.2.0 is out.

Yes, I uploaded the file directly since it is very long. ocaml-variants-7884-26640c.zip

ah yes, that sounds like a bug in the configure script of the compiler that might have to be patched. I'm not sure if the plan to bring the compilers to opam-repository include patching OCaml < 4.12 though. In the first phase, I believe (I'm not sure though) that only 4.13 and up will be covered.

illegal backslash escape in string. This error, if it is so common, I think it can be fixed uniformly, it should be unix-like system use /, while windows use \ cause, now how do I manually fix this error, try to see if it can be compiled properly?
