Unable to cross compile yara for windows on ubuntu about go-yara HOT 5 CLOSED

Why are you not using YARA 4.x? Please refer to https://pkg.go.dev/github.com/hillu/go-yara/v4#section-readme for the current version.

from go-yara.

I was getting an error while installing the package which stated that YARA version was 3 required

from go-yara.

Yes its true @preranaprabhu02
Even i wasn't able to import or use github.com/hillu/go-yara/v4
I went the other way round by cloning your git repo, and running your example, which also does'nt recognise yara package

*i have installed libyara and its working fine too.

This is a different problem than what @preranaprabhu02 reported. We really should move it to a new issue. Do you have gcc installed on your Windows system?

from go-yara.

@preranaprabhu02 I have fixed the issue on the v1.x branch and tagged v1.3.1. So, provided that you update your go.mod file to point to the 1.3.1 release (using go get github.com/hillu/[email protected]), this problem should be gone.

If you still get compiler errors such as

libyara/.libs/libyara.a(pe.o):pe.c:(.bss+0x0): multiple definition of `yr_cryptprov'; libyara/.libs/libyara.a(libyara.o):libyara.c:(.bss+0x208): first defined here

you should patch the yr_cryptprov definition in your YARA 3.11 sources, see: VirusTotal/yara#1416.

This being said, I still recommend against using YARA 3 (and go-yara 1.x) for any new projects because in the meantime quite a few security problems that might lead to code execution through maliciously crafted files have been fixed in YARA. Just use YARA 4.x (4.3.2 at the moment) and github.com/hillu/go-yara/v4.
