'cargo test' fails on Windows with PCRE2 errors

[gvanem]

What version of ripgrep are you using?

ripgrep 13.0.0
-SIMD -AVX (compiled)
+SIMD +AVX (runtime)

How did you install ripgrep?

I built it myself. A cargo build --release works fine.

What operating system are you using ripgrep on?

Win-10. 21H1. Build 19043.1706.

Describe your bug.

Running a cargo test --release, causes this link failure:

....

All in all, these 19 symbols are missing:

I even did a rustup update w/o any help.

This looks like an environment issue on Windows. Sadly, I'm not equipped to debug it as I don't use Windows.

I will say that I find it a little suspicious that it is trying to build with PCRE2 even though you didn't enable it. So if you truly are just running cargo test --release and aren't enabling the pcre2 feature, then that's the first thing to figure out.

I'm moving this to a Discussion question.

.. to build with PCRE2 even though you didn't enable it.

I thought PCRE2 was bundled in. But after a make realclean, the cargo test works now (!?)

Wat. ripgrep doesn't have a Makefile...

I'll mark this as the answer since you appear to have a strange setup.

PCRE2 support and how to build it is documented in the README and it is very clearly not enabled by default: https://github.com/BurntSushi/ripgrep#building
