Hi, I wanted to ask here before opening an issue in GH.
I'm trying out source-based coverage with nightly-2020-11-14 (on Windows and WSL).
On Windows, I have LLVM 11 installed, and on WSL I'm relying on
When trying to use llvm-profdata on Windows, to merge profraw fiies, I get:
warning: default.profraw: Profile uses zlib compression but the profile reader was built without zlib support warning: arrow/default.profraw: Profile uses zlib compression but the profile reader was built without zlib support error: No profiles could be merged.
On WSL, I get:
warning: arrow/default.profraw: Failed to uncompress data (zlib) error: No profiles could be merged.
I can get that both issues are related to LLVM being built without
zlib support, but given that i'm getting related zlib errors on both a preinstalled LLVM, and the tools that come with nightly;
Is there a solution to this issue? Or would users who want to try out the coverage have to build LLVM ourselves?
