Missing `advapi32.lib` and `uuid.lib` when compiling with dune

panglesd commented 2 years ago

I did a fresh instal of the dkml distribution of OCaml in the windows virtual machine "MSEdge on win 10" available here.

The install went well, the toplevel works, and dune is installed. However, when I generate a helloworld example using dune init proj helloworld and try to build it, I have some errors about missing .lib files: advapi32.lib and uuid.lib.

Here is the complete output:

PS C:\Users\IEUser\barouf> dune init proj he
Success: initialized project component named he
PS C:\Users\IEUser\barouf> cd he

Err ... I can't recreate your situation. I put some mitigations below, but I'd appreciate if you can first copy-and-paste what you get in the Command Prompt when you run:

C:\Users\IEUser\barouf\he>opam switch
C:\Users\IEUser\barouf\he>where.exe dune
C:\Users\IEUser\barouf\he>where.exe dune-real
C:\Users\IEUser\barouf\he>dune clean   
C:\Users\IEUser\barouf\he>set DKML_BUILD_TRACE=ON
C:\Users\IEUser\barouf\he>set DKML_BUILD_TRACE_LEVEL=2
C:\Users\IEUser\barouf\he>dune build

Mitigation 1

~~That won't work without doing the equivalent of eval $(opam env) on Windows.~~

~~I now see I've got some documentation wrong ...~~

if you are following https://diskuv.gitlab.io/diskuv-ocaml/doc/BeyondBasics.html then:

Open the Command Prompt (press the Windows key ⊞ and R, and then type “cmd” and ENTER).

should really be

Open the x64 Native Tools Command Prompt (press the Windows key ⊞, and then type “x64 native” and ENTER).

Mitigation 2

Or do a opam switch and follow the instructions (ex. for /f "tokens=*" %i in ('opam env') do @%i) in a regular Command Prompt or a PowerShell session.

panglesd commented 2 years ago

Thanks a lot for your answer!

Following your suggestion, I opened the x64 native tool command prompt, dune init proj a new project and built: It worked! Confused, I made more extensive tests, that I now report:

In a "freshly" opened x64 native tool OR cmd OR powershell, if I just create a dune project and build it, it works
In a cmd OR powershell (but NOT a x64 native tool command), if I open a "fresh" window, follow the advice given in opam switch to update my configuration, create a new project and tries to build it, it fails!

Eval environment, init proj, dune build

On the other hand, in a x64 native tool command, if I open a "fresh" window, follow the advice given in opam switch to update my configuration, create a new project and tries to build it, it works!
If I open a new powershell/cmd window, create a new switch with opam dkml init, and eval the environment (necessary, it continues to fail when coming from a failing environment), it works!

create new switch, eval environment, init project, build

So it seems that evaluating the environment to the playground switch (after a successfull build in a newly created switch, I tried to go back to the playground switch with (& opam env --switch=playground) -split '\r?\n' | ForEach-Object { Invoke-Expression $_ }) clean and build again, and it failed!

(By the way, the documentation says:

Notice how the switch was created with opam dkml init, and also notice how opam switch tells you in its [NOTE] that it knows which switch should be used based on the current directory.

If we want our my-first-switch to be remembered regardless what the directory currently is, we can follow the [WARNING] and add the option --set-switch.

But, from the last experiment, it seems that even if we are in the directory, if we do not update the environment, it won't use the local switch...

Also, when creating a new switch with opam dkml init, the message is to use eval $(opam env), which won't work on windows...

PS C:\Users\IEUser\switch_experiment> opam dkml init

Thanks for the detailed report!! I missed that you were using PowerShell, so the trace statements did not work.

Is it possible that you can repeat the following commands in PowerShell ... you will get a lot of output:

dune clean

Remove-Item -Recurse "$(opam var prefix)\.dkml\compiler-cache"

$env:DKML_BUILD_TRACE="ON"
$env:DKML_BUILD_TRACE_LEVEL=2
dune build

jonahbeckford commented 2 years ago

Bugs to be fixed (so far):

[ ] opam dkml init shows eval $(opam env). Either display nothing (see next TODO which may eliminate the need for eval) or the correct evaluation command.
[ ] Document that being in a Opam switch directory is not sufficient (you need equivalent of eval $(opam env) or make the Opam and Dune wrappers auto-select the Opam switch directory automatically. Root cause: In Windows the MSVC compiler has many environment variables that need to be set for it to work correctly, in contrast to Unix. And in Unix, you must do eval $(opam env) to get a functional dune build (same as Windows today). If Windows Dune wrapper is changed to auto-select the Opam environment, then Windows will have less commands to build projects than Unix.

It is a bit strange... Actually I do not get any output, apart from the copy-pasted error...

Which made me remark that the usual dune information are also not displayed (the kind of "progress bar). It is as if the standard output were redirected elsewhere...

This happens only in the faulty environment (powershell or bash with environment synced with playground).

I made a recording of what happens (you can ignore the first 40 seconds where my machine was lagging a bit) MSEdge - Win10.webm

jonahbeckford commented 2 years ago

Thanks for the recording! I can recreate the problem now. This will take a bit of time to figure out the solution.

jonahbeckford commented 2 years ago

There was a race condition during installation of the Dune shim; the compilation was changing based on the existence of an external file. I'm testing and packaging up Diskuv OCaml 1.0.1 which will fix this issue permanently.

For now, running the following in PowerShell inside any broken switch (ex. playground) should fix it:

opam repository set-url diskuv-1.0.0 git+https://github.com/diskuv/diskuv-opam-repository.git#v1.0.1-prerel1
opam pin add dune -k version 2.9.3+shim.1.0.1

jonahbeckford commented 2 years ago

@panglesd The new Diskuv OCaml 1.0.1 fixes this bug. I've updated the ocaml.org PR as well. https://github.com/diskuv/dkml-installer-ocaml/releases/download/v1.0.1/setup-diskuv-ocaml-windows_x86_64-1.0.1.exe

panglesd commented 2 years ago

Thanks a lot! I wanted to test your workaround but for some reason the virtual machine refused to launch... I'll definitely check the new diskuv version!

Doesn't look like a problem anymore. Can re-open if it still is an issue.
