zig build config panic due to invalid object name on windows

[bbodi]

Hi,

• zig version: 0.7.0+6e2e747b0
• zls version: bf4f653

Running zig build config run into panic on my machine due to a weird path name while it was looking for zig.exe.

Output:

Welcome to the ZLS configuration wizard! (insert mage emoji here)
Looking for 'zig' in PATH...

I debugged and the problematic path was this: C:\Program Files (x86)\Gpg4win\..\GnuPG\bin\zig.exe

I am also running into this issue. Exact same problematic path on my machine.

hmm, I had this problem too, but with a different path, and I was able to debug it. Curiously, I actually went looking into issues because I'm having trouble getting this to build on Linux, but I got it to build on Windows just fine; I then tinkered to try to reproduce your error and was able to reproduce it.

I compiled zls just fine on windows by following the current provided instructions in the readme, reproduced here for posterity:

git clone --recurse-submodules https://github.com/zigtools/zls
cd zls
zig build -Drelease-safe
zig build config # Configure ZLS

This was using zig 0.7.1 from zls commit d5aa131 on Windows. I ran this successfully inside of git bash inside of terminal.exe.

I was also able to reproduce your bug, by doing the exact same thing ... in cmd.exe. Oddly, it does not work in cmd.exe, but DOES work in Git Bash.

I also debugged this and found a problematic search path: C:\Program Files (x86)\ChucK\/bin\zig.exe (related to ChucK). I'm not sure why the ChucK installer put a backwards slash in my path, I'll file that separately over on their project.

um, do you have a directory on your path that has a .. component in it? Try removing that. Alternatively, try running this inside of git bash.

I believe this is the related issue in zig itself: ziglang/zig#6044

Does this still happen as of the latest commit?

[tau-dev]

I will try to repro this and #158 as soon as I get my installation of Windows running again.

Closed in #286, please reopen this if you still are facing issues.
