Undefined reference to 'gnu_get_libc_version' error when using alpine:3.16
as target image
#1582
Comments
Cross works by mounting the host toolchain into the image, that means you don't need rust in the image itself, only cross-compilation tools for other languages. I recognize this error, and had a way to solve it, but I can't remember where I documented it (I think the fix was installing some glibc compat package). Anyway, you should be able to get away from this by using a If you want to use a musl rust toolchain instead, use [target.x86_64-unknown-linux-musl]
image.name = "alpine:3.16"
image.toolchain = ["x86_64-unknown-linux-musl"] |
If I use the following cross configuration: [target.x86_64-unknown-linux-musl]
image.name = "alpine:3.16"
image.toolchain = ["x86_64-unknown-linux-musl"]
pre-build = [
"apk add --no-cache openssl-dev musl-dev build-base perl"
] I get the following error: Error:

oh yeah, sorry thought you were using cross from the main branch. You can install it with |

Yes, it will always do that, we dont support using rust installed in the image (although it is possible, but no reason to use the cross cli then) I'm not sure how to fix a nix rustup/rustc setup. Try setting the edit: actually, not needed, the error message suggests it's been loaded, but you can make sure with |
In the end, I was able to configure [target.x86_64-unknown-linux-musl]

Checklist
Describe your issue
I'm trying to compile a CLI that depends on
openssl
andfuse3
.I was able to statically build that CLI directly inside the docker container
alpine:3.16
.Now I would like to use
cross
for that so I've configuredtarget.x86_64-unknown-linux-musl.image
to usealpine:3.16
but when build the project I'm getting errors aboutundefined reference to 'gnu_get_libc_version'
.Another thing that's odd for me is that I've never configured the
target.x86_64-unknown-linux-musl.pre-build
to installrust
butcross
seems to use one anywaySo how
cross
is able to usecargo
if it's not provided by used the image?Is it possible to force
cross
to use what provided by the image and error out if something is missing?What target(s) are you cross-compiling for?
x86_64-unknown-linux-musl
Which operating system is the host (e.g computer cross is on) running?
What architecture is the host?
What container engine is cross using?
cross version
cross 0.2.5
Example
Execute the following commands:
Modify
src/main.rs
to be like the following:Add the following cross configuration file in
Cross.toml
Try to build with
cross build --release --target=x86_64-unknown-linux-musl
Additional information / notes
Output of:
cross b --release --target=x86_64-unknown-linux-musl
