1 week ago That looks like an issue with the Rust toolchain itself. The problem here is that the compiler is running in the aarch64 platform, but you are explicitly telling the compiler to build the binary for x86_64-unknown-linux-gnu. So, the compiler is trying to cross-compile the program for x86_64 by using the -m64 option, which is not supported by your compiler.

1 week ago hi @plusvic i have a macbook pro m1 with osx, run the dockerfile above to compile for linux amd64 (AMD64 = x86-64). did i install the wrong compiler?

1 week ago hi,
i got it to work:
Dockerfile:

}
time.Sleep(1000 * time.Second)
}build.sh:
app_name="yara_test:v1"
docker build -t ${app_name} . --platform linux/amd64output when executing the golang binary:
rule foo matched
rule bar matchedi run into a segfault with rustup - so i had to disable rosetta in the docker desktop (docker desktop 4.28.0 on my macbook pro m1): infos are here: https://github.com/rust-lang/rustup/issues/3902 and https://github.com/rust-lang/rust/issues/125430
could be helpful to add this into the docs...
how can i static link the lib libyara_x_capi to the golang app? also is there a way to use CGO_ENABLED=0 for that?

6 days ago For static link, did you tried go build -tags static_link?
https://github.com/VirusTotal/yara-x/blob/c45c8c7ad3c78174f981b6c74a5a3620c65b03d9/go/main.go#L4-L6
When you use the static_link build tag, CGO passes the --static argument to pkg-config, which means that your program will be linked with a static version of the library.
Regarding to CGO_ENABLED, it must be CGO_ENABLED=1, you can't disable CGO when you are building a Go module like this, that uses C code for interfacing with a C library.
hi,
i tried to build the lib for amd64 - but got the following error. any idea how to fix it?
docker file:
error:
