Inquiry Regarding UID Conflict in Libuipc Project - UID 18 Already Exists

[zhangchi20021216]

I'm writing to respectfully seek your guidance regarding a build error I've encountered related to a ​​UID (Unique Identifier) conflict​​.

When compiling the project (specifically when trying to run uipc_info.py), the process fails with the following assertion error:

[error] Assertion it == m_uid_to_info.end() failed. UID 18 already exists, name=AffineBodyRevoluteJoint, yours UID 18, name=StrainLimitingBaraffWitkinShell

This error occurs in the file: /src/core/builtin/uid_register.cppat line 9.

From my understanding, this suggests that both AffineBodyRevoluteJointand StrainLimitingBaraffWitkinShellare attempting to register with the same UID value of 18, which violates the requirement for unique identifiers.

I have tried to locate the source of this conflict by searching for the definitions of these UIDs within the codebase but would greatly appreciate your insight or direction on how to properly resolve this.

Could you please advise on the correct way to handle this UID conflict? Specifically:

•

Is there a designated process or a central file for assigning UIDs to prevent such conflicts?
•

Should one of these UIDs be changed, and if so, what value would be appropriate to ensure uniqueness?

Thank you for your time and assistance. I appreciate your work on this project and any help you can provide.

Sincerely,

[KemengHuang]
