[Bug]: libuuid undefined reference to 'uuid_unpack'

[daohu527]

What happened?

When building with bzlmod libuuid the following error occurs.

bazel-out/k8-fastbuild/bin/external/libuuid~/_objs/uuid/gen_uuid.pic.o:gen_uuid.c:function __uuid_generate_random: error: undefined reference to 'uuid_unpack'
bazel-out/k8-fastbuild/bin/external/libuuid~/_objs/uuid/gen_uuid.pic.o:gen_uuid.c:function uuid_generate_md5: error: undefined reference to 'uuid_unpack'
bazel-out/k8-fastbuild/bin/external/libuuid~/_objs/uuid/gen_uuid.pic.o:gen_uuid.c:function uuid_generate_sha1: error: undefined reference to 'uuid_unpack'

How to reproduce

No response

Any other information?

I find modules/libuuid/2.39.3/patches/add_build_file.patch missing

+        "libuuid/src/predefined.c",
+        "libuuid/src/unpack.c",
+        "libuuid/src/unparse.c",

and 2.39.3.bcr.1 already added. Should we change to 2.39.3.bcr.1 then

Regarding this part:

I find modules/libuuid/2.39.3/patches/add_build_file.patch missing

+        "libuuid/src/predefined.c",
+        "libuuid/src/unpack.c",
+        "libuuid/src/unparse.c",

and 2.39.3.bcr.1 already added. Should we change to 2.39.3.bcr.1 then

we can add a new version (2.39.bcr.2) with updates to the patch.

[daohu527]

I'm not expressing clear. I mean 2.39.3.bcr.1 will work. But the link https://registry.bazel.build/modules/libuuid will also recommend version 2.39.3, so do we need to confirm which version is available and which has bugs and must be upgraded.

Previously, you required that the version must be updated forward

[Wyverald]

Ah, I see. The fact that registry.bazel.build thinks 2.39.3 is the newer version is a bug, tracked at bazel-contrib/bcr-ui#142.

OK, then close
